NDAB21005U Machine Learning A (MLA)
Bsc programme in Machine Learning and Data Science
The course introduces basic theory and algorithms of machine learning. The course covers the following tentative list of topics:
- Supervised learning setting
- Unsupervised learning setting
- Concentration of measure inequalities
- Analysis of generalization in classification
- Validation and cross-validation
- Generalisation bound for a single hypothesis
- Generalisation bound for a finite hypothesis class
- Occam's razor - generalisation bound for a countably infinite hypothesis class
- K-Nearest Neighbors
- Logistic Regression
- Linear Regression
- Feature transformations and classification/regression in transformed feature spaces
- Various forms of regularisation
- Regularization terms
- Dimensionality reduction
- Random Forests and Decision Trees
- Neural Networks and introduction to Deep Learning
- Principal Component Analysis (PCA)
- Assumptions behind the algorithms taught in the course, their
implications, and common pitfalls
- Internal overfitting within algorithms due to overly complex hypothesis spaces
- Extrenal overfitting outside algorithms due to application of an excessive number of algorithms to a dataset
- The i.i.d. assumption
- The i.i.d. assumption is behind everything taught in the course
- Consequences of violation of the i.i.d. assumption
- Special case: sampling bias
- Failure of generalisation guarantees
- Implications of the i.i.d. assumption
- Biases in the training data propagate into predictions
- Correlation ≠ Causality
- The course only studies statistical correlations / dependencies in the data. Causal inference is not covered in the course.
At course completion, the successful student will have:
- the basic principles of machine learning;
- basic probability theory for modelling and analysing data;
- the theoretical concepts underlying classification, regression, and clustering;
- the mathematical foundations of selected machine learning algorithms;
- basic assumptions behind the algorithms studied in the course, their implications and common pitfalls.
- proving generalisation bounds based on validation errors;
- proving generalisation bounds for countable hypothesis classes;
- applying linear and non-linear techniques for classification and regression;
- performing elementary dimensionality reduction;
- elementary data clustering;
- implementing selected machine learning algorithms;
- visualising and evaluating results obtained with machine learning techniques;
- using software libraries for solving machine learning problems;
- identifying and handling common pitfalls in machine learning.
- recognising and describing possible applications of machine learning;
- formalising and rigorously analysing machine learning problems;
- comparing, appraising and selecting machine learning methods for specific tasks;
- solving real-world data mining and pattern recognition problems by using machine learning techniques.
