Courses
- Fine-Tuning Open Language Models with LoRA: Decide when fine-tuning pays, prepare chat data properly, and fine-tune open models with LoRA and QLoRA, from the maths and a LoRA layer of your own to transformers, peft, evaluation and serving. (Advanced, about 19 hours)
- 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)
- 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)
