Machine Learning :classification and evaluation [ LINGI2262 ]

 > https://moodleucl.uclouvain.be/course/view.php?id=8900

• Learning as search, inductive bias
• Combinations of decisions
• Loss function minimization, gradient descent
• Performance assessment
• Instance-based learning
• Probabilistic learning
• Unsupervised classification

• understand and apply standard techniques to build computer programs that automatically improve with experience, especially for classification problems
• assess the quality of a learned model for a given task
• assess the relative performance of several learning algorithms
• justify the use of a particular learning algorithm given the nature of the data, the learning problem and a relevant performance measure
• use, adapt and extend learning software

• use the technical documentation to make efficient use of existing packages,
• communicate test results in a short report using graphics.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

The 4 mini-projects worth 30 % of the final grade, 70 % for the exam (closed-book).

The mini-projects can NOT be remade in second session
30 % are already set at the end of Q2 and included as such in the final score in the second session.

• Lectures
• Written assignment and/or Miniproject (2 students/group, from 1 to 3 weeks)
• Assignment feedback

• Decision Tree Learning: ID3, C4.5, CART, Random Forests
• Linear Discriminants: Perceptrons, Gradient-Descent and Least-Square Procedures
• Maximal Margin Hyperplanes and Support Vector Machines
• Probability and Statistics in Machine Learning
