Given a minimum support threshold of 25% and a minimum confidence threshold of 50%, is this association rule strong? (b) Based on the given data, is the purchase of hot dogs independent of the purchase of hamburgers? If not, what kind of correlation relationship exists between the two? (c) Compare the use of the all_confidence, max_confidence, Kalczynski, and cosine measures with lift and correlation on the given data. 6.15 Implementation project The DBLP data set (www.informatik.uni-trier.de/~ley/db/) consists of over one million entries of research papers published in computer science conferences and journals. Among these entries, there are a good number of authors that have coauthor relationships. (a) Propose a method to efficiently mine a set of coauthor relationships that are closely correlated (e.g., often coauthoring papers together). (b) Based on the mining results and the pattern evaluation measures discussed in this chapter, discuss which measure may convincingly uncover close collaboration patterns better than others. (c) Based on the study in (a), develop a method that can rapidly predict advisor and side relationships and the approximate period for such advisory supervision. 6.6 Bibliographic Notes Association rule mining was first proposed by Agrawal, Imieliński, and Swami [AIS93]. The Apriori algorithm discussed in Section 6.2.1 for frequent itemset mining was presented in Agrawal and Srikant [AIS94]. A variation of the algorithm using a similar pruning heuristic was developed independently by Mannila, Tioven, and Verkamo. ``` #################### File:

Saunasteuergerät gewährleistet werden. Mit Ihrem Saunasteuergerät „bedienen“ Sie Ihre Saunaanlage und mit den vielen individuellen Programmiermöglichkeiten werden Sie sicher schnell die Einstellungen finden, bei denen Sie sich am wohlsten fühlen.Das Empfinden in der Sauna ist subjektiv, da-her bedarf es wirklich des eigenen Empfindens oder des der Familie, um die optimalen Einstel-lungen zu finden. Die Steuergeräte werden mit den voreingestell-ten typischen Klimawerten für eine klassische finnische Sauna bzw. bei Modellen mit Feuch-teregelung auch für eine Sauna mit Feuchtebe-trieb geliefert. In dieser Bedienungsanweisung ist beschrie-Allgemeine Hinweise zum SaunabadenVorwortben, wie Sie „Ihr Klima“ in der Kabine vorwählen können. Lesen Sie diese Anweisungen sorgfäl-tig durch, damit Sie schnell und einfach durch die Programmierung finden.Beachten Sie beim Saunabaden, dass es unter-schiedliche Temperaturen in der Kabine gibt. So ist es direkt unter der Kabinendecke am hei-ssesten, während zum Fußboden hin ein deut-liches Temperaturgefälle vorhanden ist. Umge-kehrt verhält es sich mit der relativen Feuchte, die unter der Kabinendecke am geringsten und zum Fußboden hin am höchsten ist.Aus Sicherheitsgründen ist der Temperatur-fühler mit der Übertemperatursicherung im Bereich über dem Ofen an der Kabinendecke angeordnet, da sich hier üblicherweise die hei-ßeste Zone in der Kabine befindet.Somit wird es vom Temperaturfühler des Steu-ergerätes zu Ihrem Anzeigethermometer in der Kabine immer Temperaturunterschiede geben.So kann z.B. bei einer Temperaturvorwahl von 100 °C durchaus auf Ihrem Anzeigethermome-ter ein Wert von 85°C - 90°C angezeigt werden. Dies entspricht dann auch den üblichen Klima-werten in der Kabine.Achten Sie immer auf Hygiene. Legen Sie im-mer Hand- oder Badetücher unter, damit kein Schweiß auf das Holz tropft.Bei Saunen mit Feuchtebetrieb empfehlen wir nach jedem Feuchtebad ein Nachheizen bzw. ein Nachtrocknen der Kabine, um Ihre Kabine vor möglichen Schäden durch den Feuchtebe-trieb zu schützen. Zusätzlich kann in schlecht belüfteten Räumlichkeiten ein Lüfter zum Ab-führen der verbrauchten feuchten Luft verwen-det werden.Um Zugerscheinungen in der Kabine zu ver-meiden, sollte eine Lüfterfunktion während des Saunabadens möglichst vermieden werden. Sie sollte nur eingesetzt werden, wenn es vom Kabinenhersteller empfohlen wird.Sehr geehrte Kundin, sehr geehrter Kunde,Sie haben ein hochwertiges technisches Gerät erworben, mit welchem Sie lange Jahre Freude haben werden. Dieses Gerät wurde nach den aktuellen europäischen Sicherheitsnormen konstruiert, geprüft und im Herstellerwerk nach der Qualitätsmanagementnorm DIN EN ISO 9001:2015 gefertigt.Zu Ihrer Information ist diese ausführliche Montage- und Gebrauchsanweisung für Sie erstellt worden. Beachten Sie insbesondere die wichtigen Hinweise und die Angaben zum elektrischen Anschluss.Wir wünschen Ihnen eine anregende Erholung und ein erlebnisreiches Wellness-Bad. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 74 Context: coveringregressionandothertopicsinstatis-ticalanalysis,suchasMathematicalStatistics:BasicIdeasandSelectedTopicsbyBickelandDoksum[BD01];TheStatisticalSleuth:ACourseinMethodsofDataAnalysisbyRamseyandSchafer[RS01];AppliedLinearStatisticalModelsbyNeter,Kutner,Nacht-sheim,andWasserman[NKNW96];AnIntroductiontoGeneralizedLinearModelsbyDobson[Dob90];AppliedStatisticalTimeSeriesAnalysisbyShumway[Shu88];andAppliedMultivariateStatisticalAnalysisbyJohnsonandWichern[JW92].Researchinstatisticsispublishedintheproceedingsofseveralmajorstatisticalcon-ferences,includingJointStatisticalMeetings,InternationalConferenceoftheRoyalStatisticalSocietyandSymposiumontheInterface:ComputingScienceandStatistics.OthersourcesofpublicationincludetheJournaloftheRoyalStatisticalSociety,TheAnnalsofStatistics,theJournalofAmericanStatisticalAssociation,Technometrics,andBiometrika.TextbooksandreferencebooksonmachinelearningandpatternrecognitionincludeMachineLearningbyMitchell[Mit97];PatternRecognitionandMachineLearningbyBishop[Bis06];PatternRecognitionbyTheodoridisandKoutroumbas[TK08];Introduc-tiontoMachineLearningbyAlpaydin[Alp11];ProbabilisticGraphicalModels:Principles #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 664 Context: HAN20-ch13-585-632-97801238147912011/6/13:26Page627#4313.7Exercises62713.6(Researchproject)Buildingatheoryofdataminingrequiressettingupatheoreticalframeworksothatthemajordataminingfunctionscanbeexplainedunderthisframework.Takeonetheoryasanexample(e.g.,datacompressiontheory)andexaminehowthemajordataminingfunctionsfitintothisframework.Ifsomefunctionsdonotfitwellintothecurrenttheoreticalframework,canyouproposeawaytoextendtheframeworktoexplainthesefunctions?13.7Thereisastronglinkagebetweenstatisticaldataanalysisanddatamining.Somepeoplethinkofdataminingasautomatedandscalablemethodsforstatisticaldataanalysis.Doyouagreeordisagreewiththisperception?Presentonestatisticalanalysismethodthatcanbeautomatedand/orscaledupnicelybyintegrationwithcurrentdataminingmethodology.13.8Whatarethedifferencesbetweenvisualdatamininganddatavisualization?Datavisu-alizationmaysufferfromthedataabundanceproblem.Forexample,itisnoteasytovisuallydiscoverinterestingpropertiesofnetworkconnectionsifasocialnetworkishuge,withcomplexanddenseconnections.Proposeavisualizationmethodthatmayhelppeopleseethroughthenetworktopologytotheinterestingfeaturesofasocialnetwork.13.9Proposeafewimplementationmethodsforaudiodatamining.Canweintegrateaudioandvisualdataminingtobringfunandpowertodatamining?Isitpossibletodevelopsomevideodataminingmethods?Statesomescenariosandyoursolutionstomakesuchintegratedaudiovisualminingeffective.13.10General-purposecomputersanddomain-independentrelationaldatabasesystemshavebecomealargemarketinthelastseveraldecades.However,manypeoplefeelthatgenericdataminingsystemswillnotprevailinthedataminingmarket.Whatdoyouthink?Fordatamining,shouldwefocusoureffortsondevelopingdomain-independentdataminingtoolsorondevelopingdomain-specificdataminingsolutions?Presentyourreasoning.13.11Whatisarecommendersystem?Inwhatwaysdoesitdifferfromacustomerorproduct-basedclusteringsystem?Howdoesitdifferfromatypicalclassificationorpredictivemodelingsystem?Outlineonemethodofcollaborativefiltering.Discusswhyitworksandwhatits #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 663 Context: esearchpapers,conference,authors,andtopics).Whatarethemajordifferencesbetweenmethodologiesforminingheterogeneousinformationnetworksandmethodsfortheirhomogeneouscounterparts?13.4Researchanddescribeadataminingapplicationthatwasnotpresentedinthischapter.Discusshowdifferentformsofdataminingcanbeusedintheapplication.13.5Whyistheestablishmentoftheoreticalfoundationsimportantfordatamining?Nameanddescribethemaintheoreticalfoundationsthathavebeenproposedfordatamin-ing.Commentonhowtheyeachsatisfy(orfailtosatisfy)therequirementsofanidealtheoreticalframeworkfordatamining. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 118 Context: # 2.7 Bibliographic Notes Methods for descriptive data summarization have been studied in the statistics literature long before the onset of computers. Good summaries of statistical descriptive data mining methods include Freedman, Pisani, and Purves [FP07] and Devore [Dev95]. ## 2.6 Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8): 1. Compute the Euclidean distance between the two objects. 2. Compute the Manhattan distance between the two objects. 3. Compute the Minkowski distance between the two objects, using \( q = 3 \). 4. Compute the supremum distance between the two objects. ## 2.7 The median is one of the most important holistic measures in data analysis. Propose several methods for median approximation. Analyze their respective complexity under different parameter settings and decide to what extent the real value can be approximated. Moreover, suggest a heuristic strategy to balance between accuracy and complexity and then apply it to all methods you have given. ## 2.8 It is important to define or select similarity measures in data analysis. However, there is no commonly accepted subjective similarity measure. Results can vary depending on the similarity measures used. Nonetheless, seemingly different similarity measures may be equivalent after some transformation. Suppose we have the following 2-D data set: | | A₁ | A₂ | |-----|-----|-----| | x₁ | 1.5 | 1.7 | | x₂ | 2.2 | 1.9 | | x₃ | 1.6 | 1.8 | | x₄ | 1.2 | 1.5 | | x₅ | 1.5 | 1.0 | 1. Consider the data as 2-D data points. Given a new data point, \( x = (1.4, 1.6) \) as a query, rank the database points based on similarity with the query using Euclidean distance, Manhattan distance, supremum distance, and cosine similarity. 2. Normalize the data set to make the norm of each data point equal to 1. Use Euclidean distance on the transformed data to rank the data points. #################### File: ECON_D1-R4.35_-_MA_de.pdf Page: 23 Context: # Individuelle Einstellungen Im Folgenden zeigen wir Ihnen Möglichkeiten, die Ihnen die Anpassung der Steuerungen an Ihre individuellen Bedürfnisse erlauben.

![Visualization of the Iris data set using a scatter-plot matrix.](http://support.sas.com/documentation/callen/grstatproc/61984/HTML/default/images/ggscanct.gif) **Figure 2.15** Visualization of the Iris data set using a scatter-plot matrix. Viewing large tables of data can be tedious. By condensing the data, Chernoff faces make the data easier for users to digest. In this way, they facilitate visualization of regularities and irregularities present in the data, although their power in relating multiple relationships is limited. Another limitation is that specific data values are not shown. Furthermore, facial features vary in perceived importance. This means that the similarity of two faces (representing two multidimensional data points) can vary depending on the order in which dimensions are assigned to facial characteristics. Therefore, this mapping should be carefully chosen. Eye size and eyebrow shape have been found to be important. Asymmetrical Chernoff faces were proposed as an extension to the original technique. Since a face has vertical symmetry (along the y-axis), the left and right side of a face are identical, which wastes space. Asymmetrical Chernoff faces double the number of facial characteristics, thus allowing up to 36 dimensions to be displayed. The stick figure visualization technique maps multidimensional data to five-piece stick figures, where each figure has four limbs and a body. Two dimensions are mapped to the display (x and y axes) and the remaining dimensions are mapped to the angle. Image Analysis: ## Image Analysis ### 1. Localization and Attribution - **Image 1**: The entire page consists of six scatter plots in a matrix formation with descriptive text at the bottom. ### 2. Object Detection and Classification - **Image 1**: Detected objects include scatter plots with data points and text legends. - Objects: Scatter plots, data points, axes, and legends. ### 3. Scene and Activity Analysis - **Image 1**: The scene consists of scatter plots comparing four flower attributes in the Iris dataset: sepal length, sepal width, petal length, and petal width. The plots are used to analyze the relationships between these attributes. ### 4. Text Analysis - **Image 1**: The detected text includes the titles of the scatter plots, such as "Sepal length (mm)" and "Petal width (mm)," as well as species categories (Iris Setosa, Versicolor, Virginica). - The text provides labels and context for each plot and how data points are categorized by species. ### 5. Diagram and Chart Analysis - **Image 1**: The diagrams illustrate scatter plots of the Iris dataset. - **Axes**: Each plot has an x-axis and y-axis, measured in millimeters. - **Legend**: Indicates the species classification for data points. - **Key Insights**: The scatter plots reveal correlations and variances between different flower attributes across species. ### 12. Graph and Trend Analysis - **Image 1**: Trends indicate clustering of species based on attributes: - **Sepal length vs. Sepal width**: Some overlap with distinct clustering. - **Petal length vs. Petal width**: Clear separation among species. ### Abläufeprozesse und Prozessbeschreibungen (Process Flows and Descriptions) - **Image 1**: The process involves visualizing data to identify patterns and relationships within the Iris dataset. ### Trend and Interpretation - **Image 1**: The scatter plots suggest patterns in the Iris data that could help in predicting species based on flower measurements. ### Contextual Significance - **Image 1**: This visual content is likely part of a data visualization section in a document, illustrating how to use scatter plots to understand multidimensional data. Overall, the scatter plots provide a visual analysis method to assess relationships between different attributes of the Iris dataset, offering insights into data clustering and species differentiation. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 11 Context:

However, the shorter term, **knowledge mining**, may not reflect the emphasis on mining from large amounts of data. Nevertheless, mining is a vivid term characterizing the process that finds a small set of precious nuggets from a great deal of raw material (Figure 1.3). Thus, such a misnomer carrying both “data” and “mining” became a popular choice. In addition, many other terms have a similar meaning to data mining—for example, **knowledge mining from data**, **knowledge extraction**, **data/pattern analysis**, **data archaeology**, and **data dredging**. Many people treat data mining as a synonym for another popularly used term, **knowledge discovery from data**, or **KDD**, while others view data mining as merely an essential step in the process of knowledge discovery.

Because data mining is a relatively young discipline with wide and diverse applications, there is still a nontrivial gap between general principles of data mining and application-specific, effective data mining tools. In this section, we examine several application domains, as listed in Figure 13.12. We discuss how customized data mining methods and tools should be developed for such applications. ## 13.3.1 Data Mining for Financial Data Analysis Most banks and financial institutions offer a wide variety of banking, investment, and credit services (the latter include business, mortgage, and automobile loans and credit cards). Some also offer insurance and stock investment services. ![Figure 13.11 Perception-based classification, an interactive visual mining approach.](path/to/image) - Attribute: Records: 937 - Tools: - File - Options - View - Help - Operations: - Work in progress - Work in progress - Work in progress Relaxing than visual mining.

For example, the data distribution in a set of attributes can be displayed using colored sectors (where the whole space is represented by a circle). This display helps users determine which sector should first be selected for classification and where a good split point for this sector may be. An example of this is shown in **Figure 13.11**, which is the output of a perception-based classification (PBC) system developed at the University of Munich. - **Audio data mining** uses audio signals to indicate the patterns of data or the features of data mining results. Although visual data mining may disclose interesting patterns using graphical displays, it requires users to concentrate on watching patterns and identifying interesting or novel features within them. This can sometimes be quite tiresome. If patterns can be transformed into sound and music, then instead of watching pictures, we can listen to pitch, rhythm, tune, and melody to identify anything interesting or unusual. This may relieve some of the burden of visual concentration and be more effective. Image Analysis: ## Localization and Attribution: - **Image 1:** Located centrally on the page, consisting of multiple panels and graphs. ## Object Detection and Classification: - **Image 1:** - **Graphs and Charts:** Multiple graph panels display data points, trends, and scatter plots. - **Tables:** Numerical data is organized in tabular form, indicating various data categories. ## Diagram and Chart Analysis: - **Image 1:** - **Scatter Plots:** Display relationships between different variables, useful for identifying patterns in data mining. - **Tables:** Present numerical data, possibly summarizing data statistics or categorizing information related to the visualizations. ## Text Analysis: - **Text Excerpt:** Describes the use of interactive visual data mining tools to assist users in making data-driven decisions, highlighting the significance of visual aids in understanding complex data. ## Contextual Significance: - **Image Contribution:** Demonstrates how SAS Enterprise Miner is used for visualizing data mining results, illustrating several types of data relationships and results analytics. Overall, the visual content demonstrates the application of visual tools in SAS Enterprise Miner to facilitate decision-making in data mining through graphical representations of data patterns and trends. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 117 Context: # Chapter 2 Getting to Know Your Data ## 2.2 Data Analysis: Attribute Age Suppose that the data for analysis includes the attribute age.

that effectively capture the meaning of the given patterns. The experiment demonstrates the effectiveness of semantic pattern annotation to generate a dictionary-like annotation for frequent patterns, which can help a user understand the meaning of annotated patterns. The context modeling and semantic analysis method presented here is general and can deal with any type of frequent patterns with context information. Such semantic annotations can have many other applications such as ranking patterns, categorizing and clustering patterns with semantics, and summarizing databases. Applications of the pattern context model and semantics analysis method are also not limited to pattern annotation; other example applications include pattern compression, transaction clustering, pattern relations discovery, and pattern synonym discovery. ## 7.6.2 Applications of Pattern Mining We have studied many aspects of frequent pattern mining, with topics ranging from efficient mining algorithms and the diversity of patterns to pattern interestingness, pattern #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29%281%29.pdf

Image Analysis: 1. **Localization and Attribution:** - Image 1: The entire page contains a single aerial image. 2. **Object Detection and Classification:** - The image features several identifiable objects including: - A runway and associated airport structures. - Areas of dense greenery, possibly a golf course. - Housing and miscellaneous buildings surrounding the central structures. 3. **Scene and Activity Analysis:** - The scene appears to be an aerial view of an airport and its surrounding areas. The runway is prominent, indicating aviation activities. There are no visible activities due to the scale and nature of the image. 8. **Color Analysis:** - Dominant colors include various shades of green, indicative of vegetation and fields. - Greys and blacks are present, representing the runway and roads. - Red and orange hues can be noticed in the roofings and some areas around buildings, typical of urban housing. 9. **Perspective and Composition:** - The image is taken from a bird’s eye view, capturing a wide expanse of land including the airport, adjacent green areas, and urban development. - The composition is centered on the runway, with other elements such as housing and fields forming an outer frame. 10. **Contextual Significance:** - This image potentially contributes to a geographical or urban planning document, providing an overview of infrastructural layout and land use around an airport. It gives insights into the blend of aviation, recreational, and residential spaces. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 99 Context: # Chapter 2 Getting to Know Your Data ## Figure 2.16 Here is a visualization that uses parallel coordinates.

Figure 2.18 shows census data, where age and income are mapped to the display axes, and the remaining dimensions (gender, education, and so on) are mapped to stick figures. If the data items are relatively dense with respect to the two display dimensions, the resulting visualization shows texture patterns, reflecting data trends. Image Analysis: ### Localization and Attribution - **Image 1:** Top of the page, labeled as Figure 2.16. - **Image 2:** Below the first image, labeled as Figure 2.17. ### Diagram and Chart Analysis **Image 1 (Figure 2.16):** - **Type:** Parallel Coordinates Chart. - **Axes:** X1 to X10 on the horizontal axis; Y-axis ranges from -10 to 10. - **Data Trends:** The visualization connects data points to explore multi-dimensional data relationships. The crisscrossing lines represent different items or entities across ten attributes. The intricate pattern suggests variance and correlations among the data points. ### Object Detection and Classification **Image 2 (Figure 2.17):** - **Objects:** Chernoff faces. - **Classification:** Each face is an n-dimensional data representation. - **Key Features:** Faces have varying shapes, sizes, and expressions, representing different data dimensions like eyebrows, eyes, nose, and mouth. ### Scene and Activity Analysis **Image 1 (Figure 2.16):** - **Scene:** A technical graph demonstrating data visualization techniques using parallel coordinates. - **Activity:** The chart visualizes complex multi-dimensional datasets. **Image 2 (Figure 2.17):** - **Scene:** Visualization of data using human facial characteristics. - **Activity:** Chernoff faces are used to convey multivariate data, providing quick visual cues to identify patterns. ### Text Analysis - **Captured Text:** - "Figure 2.16 Here is a visualization that uses parallel coordinates. Source: www.stat.columbia.edu/~cook/movabletype/archives/2007/10/parallel_coordi.html." - "Figure 2.17 Chernoff faces. Each face represents an n-dimensional data point (n ≤ 18)." - **Significance:** The text explains the purpose and type of each visualization, indicating that these figures are used to better understand and communicate data sets. ### Trend and Interpretation - **Parallel Coordinates (Image 1):** Identify relationships across multiple dimensions, showcasing the interplay and variability between various attributes. - **Chernoff Faces (Image 2):** Simplifies complex data into intuitive visual patterns using facial characteristics, allowing for ease of interpretation in comparative analysis. These images contribute to the broader context by demonstrating advanced methods of data visualization, aiming to simplify and enhance understanding of multi-dimensional data sets for more informed

Compare the efficiency of the two mining processes. (b) List all the strong association rules (with support \( s \) and confidence \( c \)) matching the following metarule, where \( X \) is a variable representing customers, and \( item \) denotes variables representing items (e.g., "A", "B"): \[ V_{X} = \text{transaction}, \text{buy}(X, item), \text{buy}(X, items) \Rightarrow \text{buy}(X, items), \, [s, c] \] ## 6.7 Implementation Project Using a programming language that you are familiar with, such as C++ or Java, implement three frequent item mining algorithms introduced in this chapter: (1) Apriori [AS94], (2) FP-growth [HY00], and (3) Eclat [ZHak01] (mining using the vertical data format). Compare the performance of each algorithm with various kinds of large data sets. Write a report to analyze the situations (e.g., data size, data distribution, minimum support threshold setting, and pattern density) under which one algorithm may perform better than the others, and state why. ## 6.8 Database has four transactions. **min_sup = 60% and min_conf = 80%.** | cust_ID | TID | items.bought | |---------|------|----------------------------------------------| | 01 | T100 | {King's-Crab, Sunset-Milk, Dairyland-Cheese, Best-Bread} | | 02 | T210 | {Best-Cheese, Dairyland-Milk, Goldenrod-Apple, Tasty-Pie, Wonder-Bread} | | 03 | T300 | {Westcoat-Apple, Dairyland-Milk, Wonder-Bread, Tasty-Pie} | | 04 | T400 | {Wonder-Bread, Sunset-Milk, Dairyland-Cheese} | (a) At the granularity of `item.category` (e.g., item could be "Milk"), for the rule template: \[ V_{X} = \text{transaction}, \text{buy}(X, item), \text{buy}(X, items) \Rightarrow \text{buy}(X, items), \, [s, c] \] list the frequent k-itemset for the largest \( k \), and all the strong association rules (with their support \( s \) and confidence \( c \) including the frequent k-itemset for the largest \( k \). (b) At the granularity of `brand-item.category` (e.g., item could be "Sunset-Milk"), for the rule template: \[ V_{X} = \text{customer}, \text{buy}(X, item), \text{buy}(X, items) \Rightarrow

Mining data distributions in multidimensional space. Visual display can help give users a clear impression and overview of the data characteristics in a large data set. ## Data Mining Result Visualization Visualization of data mining results is the presentation of the results or knowledge obtained from data mining in visual forms. Such forms may include scatter plots and boxplots (Chapter 2), as well as decision trees, association rules, clusters, outliers, and generalized rules. For example, scatter plots are shown in Figure 13.6 from SAS Enterprise Miner. Figure 13.7, from MineSet, uses a plane associated with a set of pillars to describe a set of association rules mined from a database. Figure 13.8, also from MineSet, presents a decision tree. Figure 13.9, from IBM Intelligent Miner, presents a set of clusters and the properties associated with them. ## Data Mining Process Visualization This type of visualization presents the various processes of data mining in visual forms so that users can see how the data are extracted and from which database or data warehouse they are extracted, as well as how the selected data are cleaned, integrated, preprocessed, and mined. Moreover, it may also show which method is selected for data mining, where the results are stored, and how they may be viewed. Figure 13.10 shows a visual presentation of data mining processes by the Clementine data mining system. Image Analysis: **Localization and Attribution:** - **Image 1:** The image is positioned at the top of the page, labeled as "Figure 13.5." It corresponds to a graphical representation related to data mining methodologies. **Object Detection and Classification:** - The image contains graphical elements such as scatter plots and data charts commonly used in data mining visualization. These can be classified under data visualization tools. **Scene and Activity Analysis:** - The scene likely depicts a software interface or a visual tool for analyzing multidimensional data distributions. The activities seem to involve interaction with visual data representations for mining and analysis purposes. **Text Analysis:** - Text in the image includes technical terms like "scatter plots," "association rules," and references to "StatSoft" indicating the source. This text underlines the context of data mining methods and tools used for analysis. - The surrounding text explains the role of visualization in understanding data distributions and mining results, emphasizing its importance in data mining processes. **Diagram and Chart Analysis:** - The diagrams and charts in the image illustrate the distribution of data in a multidimensional space. Such visualizations are crucial for identifying patterns, clusters, and outliers in a large dataset. The overlays and structural design suggest different types of data associations and rules. **Contextual Significance:** - This image and its accompanying text are part of a broader document about data mining methodologies. The visual content helps convey complex data relationships in an accessible format, enhancing the reader's understanding of data analysis tools. **Perspective and Composition:** - The perspective appears to be a straightforward, front-facing view typical of software interface screenshots, providing clarity and focusing on the visualizations and data arrangement. **Trend and Interpretation:** - The visual content suggests interpretative insights into multidimensional data, highlighting trends such as clustering and distribution patterns. It aids in understanding how data mining processes extract and represent knowledge visually. #################### File:
