====== Learning goals – Obiettivi del corso ======
… 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.
Data, data everywhere. The Economist, Special Report on Big Data, Feb. 2010.
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:
- 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

====== Exams ======
===== Exam DM part I (DMF) ======
The exam is composed of three parts:
* 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 November and December.
* An oral exam (optional) , 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. It is optional for students passing the written part by ONLY mid-term tests.
* A project consists in exercises that require the use of data mining tools for analysis of data. Exercises include: data understanding, clustering analysis, frequent pattern mining, and classification. The project has to be performed by min 3, max 4 people. It has to be performed by using Knime, Python 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 paper must emailed to datamining [dot] unipi [at] gmail [dot] com. Please, use “[DM 2018-2019] Project 2” in the subject. Students who will decide to perform the project during the winter exam sessions, or summer exam sessions will find the dataset of the project online after 31/05/2019. In this case the project must be delivered at least 2 days before the oral exam.
Tasks of the project:
- Data Understanding (Collective discussion on: 19/10/2018): Explore the dataset with the analytical tools studied and write a concise “data understanding” report describing data semantics, assessing data quality, the distribution of the variables and the pairwise correlations. (see Guidelines for details)
- Clustering analysis (Collective discussion on: 21/11/2018): Explore the dataset using various clustering techniques. Carefully describe your's decisions for each algorithm and which are the advantages provided by the different approaches. (see Guidelines for details)
- Classification (Collective discussion on: 12/12/2018): Explore the dataset using classification trees and random forest. Use them to predict the target variable. (see Guidelines for details)
- Association Rules (Collective discussion on: 12/12/2018): Explore the dataset using frequent pattern mining and association rules extraction. Then use them to predict a variable either for replacing missing values or to predict target variable. (see Guidelines for details)
* Project 1
- Dataset: Credit Card Default
- Assigned: 01/10/2018
- Deadline: 05/01/2019, 09/01/2019
- Link: https://www.kaggle.com/t/5d7277746f8d45d6a10686506f602a9b
* Project 2
- Dataset: Telco Customer Churn
- Assigned: 10/01/2019
- Deadline: 31/05/2019
- Link: https://www.kaggle.com/blastchar/telco-customer-churn
Guidelines for the project are here.
===== Exam DM part II (DMA) ======
The exam is composed of three parts:
* 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: 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 [dot] nanni [at] isti [dot] cnr [dot] 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: IBM stocks (source: 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 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.
