Courses

  • Introduction to Neural Networks and TensorFlow: Build neural networks from the single neuron up: code a perceptron and backpropagation in NumPy, then train and evaluate feed-forward networks with TensorFlow and Keras. (Intermediate, about 13 hours)
  • Recommender Systems: From Collaborative Filtering to Two-Tower Models: Build, evaluate and improve recommenders in Python: neighbourhood methods, matrix factorisation, implicit ALS and two-tower retrieval in PyTorch, with honest offline evaluation and cold-start strategies. (Advanced, about 15 hours)
  • Reinforcement Learning: From Bandits to Policy Gradients: Learn how agents learn from reward, from bandits and dynamic programming through Monte Carlo, TD learning, SARSA and Q-learning to deep Q-networks and policy gradients in PyTorch. (Advanced, about 16 hours)
  • Training Deep Neural Networks: Diagnose and fix what stops deep networks learning: vanishing and exploding gradients, slow or unstable optimisation, overfitting and badly scaled activations, in TensorFlow and Keras. (Advanced, about 14 hours)
  • Rust Programming with RustRover: Write fast, memory-safe Rust in RustRover: ownership and borrowing, enums and pattern matching, traits and generics, iterators, tests and a command-line tool. (Intermediate, about 14 hours)
