-** ... a new kind of professional has emerged, the data scientist, who combines the skills of software programmer, statistician and storyteller/artist to extract the nuggets of gold hidden under mountains of data. Hal Varian, Google’s chief economist, predicts that the job of statistician will become the "sexiest" around. Data, he explains, are widely available; what is scarce is the ability to extract wisdom from them. **

-La grande disponibilità di dati provenienti da database relazionali, dal web o da altre sorgenti motiva lo studio di tecniche di analisi dei dati che permettano una migliore comprensione ed un più facile utilizzo dei risultati nei processi decisionali. L'obiettivo del corso è quello di fornire un'introduzione ai concetti di base del processo di estrazione di conoscenza, alle principali tecniche di data mining ed ai relativi algoritmi. Particolare enfasi è dedicata agli aspetti metodologici presentati mediante alcune classi di applicazioni paradigmatiche quali il Basket Market Analysis, la segmentazione di mercato, il rilevamento di frodi. Infine il corso introduce gli aspetti di privacy ed etici inerenti all’utilizzo di tecniche inferenza sui dati e dei quali l’analista deve essere a conoscenza.  Il corso consiste delle seguenti parti:
+====== Hours and Rooms ======
-  - i concetti di base del processo di estrazione della conoscenza: studio e preparazione dei dati, forme dei dati, misure e similarità dei dati;
-  - le principali tecniche di datamining (regole associative, classificazione e clustering). Di queste tecniche si studieranno gli aspetti formali e implementativi;
-  - alcuni casi di studio nell’ambito del marketing e del supporto alla gestione clienti, del rilevamento di frodi e di studi epidemiologici.
-  - l’ultima parte del corso ha l’obiettivo di  introdurre gli aspetti di privacy ed etici inerenti all’utilizzo di tecniche inferenza sui dati e dei quali l’analista deve essere a conoscenza

+The dates relating to the start of the three exams are/will be published on the online platform
+https://esami.unipi.it/. Within each session, we will identify dates and slots in order to distribute the
+various orals. The dates and slots to take the exam will be published on the course page by the end of
+May. Each student must also register on https://esami.unipi.it/. The examination can only be carried out after the delivery of the project. The project must be delivered one week before when you want to take the exam. Group oral discussions will be preferred in respect of the project groups in order to parallelize any discussion on the project. It is not mandatory to take the oral exam together with the other members of the group.
+In the event that the oral exam is not passed, it will not be possible to take it for 20 days. If the project is not considered sufficient, it must be carried out again on a new dataset or a very updated version of the current one.

-===== Exam DM part II (DMA) ======
+  * **Dataset**
+    - Assigned: 18/02/2026
+    - MidTerm Submission: 07/05/2026
+    - Final Submission: one week before the oral exam (complete project required).
+    - Dataset: TBD
-The exam is composed of three parts:
+** DM2 Project Guidelines **
+See TBD.
-  * A **written exam**, with exercises and questions about methods and algorithms presented during the classes. It can be substitute with the first and second mid-term tests of April and June.
-  * A small **online test** for the data ethics part. The test can be taken at the following link: [[https://thinfi.com/2etq|Link to "First Aid for Data Scientist" web site]] (pwd: datamining_2018). Register, and enroll to the "First Aid for Data Scientist" course. Take the quizzes of the 3 units. Then, download your certificate and send it to [[mirco.nanni@isti.cnr.it]] before the oral exam.
-  * An **oral exam**, that includes: (1) discussing the project report with a group presentation; (2) discussing topics presented during the classes, including the theory of the parts already covered by the written exam.
-  * A **project** consists in exercises that require the use of data mining tools for analysis of data. Exercises include: sequential patterns, time series, classification (alternative methods and validation), outlier detection. The project has to be performed by max 3 people. It has to be performed by using Knime, Python, other software or a combination of them. The results of the different tasks must reported in a unique paper. The total length of this paper must be max 20 pages of text including figures.  The project must be delivered at least 2 days before the oral exam:
-     * **Time series**: given the 50+ years long history of stock values of a company, split it into years, and study their similarities, also using clustering. **Objectives**: compare similarities, compute clustering. **Dataset**: {{ :dm:dm2018_project_1.zip |IBM stocks}} (source: [[https://finance.yahoo.com/quote/IBM/history?period1=-252378000&period2=1523656800&interval=1d&filter=history&frequency=1d&guccounter=1|Yahoo Finance]]), includes a Python snippet to read and split the data. Dataset obtained from Yahoo!Finance service.
-     * **Sequential patterns**: discover patterns over the stock value time series above. Before that, preprocess the data by splitting it into monthly time series and discretizing them in some way. **Objective**: find Motifs-like patterns (i.e. frequent contiguous subsequences) of length at least 4 days. **Dataset**: same as the point before.
-     * **(Alternative) Classification methods**: test different classification methods over a simple classification problem. **Dataset**: the [[https://archive.ics.uci.edu/ml/datasets/Abalone|UCI Abalone dataset]], containing various features of abalones, including the age -- to be inferred by the number or rings. **Objective**: (i) discard the "Infant" abalones; (ii) discretize the attribute "Number of rings" into 2 classes; (iii) try at least 3 different classification methods (among those discussed in DM2, including ensemble methods) on the resulting dataset, using the discretized n. of rings as class, and evaluating them with cross-validation.
-     * **Outlier detection**: from the Abalone dataset used above, identify the top 1% outliers. **Objective**: adopt at least two different methods belonging to different families (i.e. model-based, distance-based, density-based, angle-based, ...) to identify the 1% of input records with the highest likelihood of being outliers, and compare the results. **Dataset**: same as the point before.

+** ... a new kind of professional has emerged, the data scientist, who combines the skills of software programmer, statistician and storyteller/artist to extract the nuggets of gold hidden under mountains of data. Hal Varian, Google’s chief economist, predicts that the job of statistician will become the "sexiest" around. Data, he explains, are widely available; what is scarce is the ability to extract wisdom from them. **
