3 – Kernel Methods

Webinar 3: KERNEL METHODS

Kernel methods enable more powerful non-linear functions to be estimated using linear methods through the use of the so-called kernel trick. The lecture will introduce the principles behind this approach through the examples of kernel ridge regression and kernel perceptron algorithm.

9 – Reinforcement learning

Webinar 9: Reinforcement Learning

The session is designed to provide a comprehensive overview of RL, understanding its core concepts, key algorithms, practical applications, and the challenges it faces. We begin by defining RL and distinguishing it from other types of machine learning, namely supervised and unsupervised learning. The session includes a detailed explanation of Markov Decision Processes (MDPs), which serve as the mathematical framework for RL, highlighting states, actions, transition probabilities, and rewards. The concepts of policies, value functions, and the exploration-exploitation trade-off are also examined to give participants a robust understanding of how RL agents learn and make decisions. The core of the session focuses on key RL algorithms, starting with classical methods such as Dynamic Programming, including policy iteration and value iteration. We then explore Monte Carlo methods and Temporal Difference learning, with specific emphasis on Q-Learning and SARSA. Advanced methods such as Deep Q-Networks (DQN) method is also covered, illustrating how deep learning integrates with RL to solve complex problems.

8 – Learning Evaluation

Webinar 8: Learning Evaluation

Learning evaluation is crucial in assessing the performance and reliability of machine learning models. Trainees will grasp the importance of separating data into train, validation, and test sets to ensure unbiased evaluation. Performance metrics for classifiers and regressors, including error, precision, recall, and confusion matrix, will be elucidated to measure model effectiveness. Additionally, techniques such as cross-validation aid in robust performance evaluation. Trainees will learn to tune model parameters using validation sets and gain insights into understanding model behaviors, pitfalls, and implications of decisions. This session serves as a primer for trainees to navigate the intricacies of model evaluation, fostering informed decision-making in machine learning applications.

7 – AI-Search

Webinar 7: AI-SEARCH

AI-search is a foundational aspect of problem-solving, essential in modern AI applications. This session introduces trainees to key concepts such as state space representation, uninformed and heuristic graph search algorithms, and complexities analysis. Trainees will learn to navigate problem spaces efficiently through algorithms like breadth-first search, depth-first search, and A* search, balancing optimality and computational efficiency. Understanding the space and time complexities of these algorithms enables effective problem-solving strategy selection. Additionally, the session covers strategies for two-player adversarial games, including minimax search and alpha-beta pruning, enhancing trainees’ ability to compete in dynamic environments. Mastering these concepts equips trainees with essential skills for tackling diverse real-world challenges.
