HUMAN DATA ANALYTICS

Second cycle degree in DATA SCIENCE

Campus: PADOVA

Language: English

Teaching period: Second Semester

Lecturer: MICHELE ROSSI

Number of ECTS credits allocated: 6


Syllabus
Prerequisites: A basic course on probability theory is recommended. A basic programming course is also advised for a correct comprehension of the material.
Examination methods: The exam will be a written project where the student will have to solve a selected classification problem for a given dataset. The student will have to work on the code (software), produce and discuss the results.
Course unit contents: Part I – Introduction
- Intro: course outline, grading rules, office hours, etc.
- Applications: health, activity-aware services, security and emergency management, authentication systems, analyzing human dynamics

Part II - Tools
- Vector quantization (VQ):
-- Aims, quality metrics
-- Unsupervised VQ algorithms:
--- Self-Organizing Maps (SOM), Time Adaptive-SOM (TASOM)
--- Gas Neural Networks (GNG)

- Deep Neural Networks (DNN)
-- Neural networks brief: concept, examples, training
-- Convolutional Neural Networks (CNN): structure, training

- Sequential Data Analysis:
-- Hidden Markov Models (HMM):
--- Maximum Likelihood for the HMM
