Training Deep Neural Networks: Keras, TensorFlow, and Tabular Data
Training a neural network means turning a mathematical prediction rule into an experiment: prepare the data, choose an objective, update parameters, and measure performance on unseen…

Deep Learning for Computer Vision: Building Convolutional Neural Networks from Scratch
Images contain structure: neighboring pixels form edges, edges combine into shapes, and shapes help identify objects. A convolutional neural network, or CNN, builds that structure into…

Deep Learning for Computer Vision: Transfer Learning, Fine-Tuning, and Hugging Face
Training every visual feature from random initialization can be wasteful when you have only a few hundred labeled images. Transfer learning starts from representations learned on another…

Deep Learning for Natural Language: Word Embeddings
A word ID tells a model which token it has encountered, but says nothing about what that token means. Word embeddings replace isolated token indicators with learned dense vectors. This…

Deep Learning for Natural Language: Transformers
A static embedding gives a token one vector. A Transformer combines token representations with information about their positions and surrounding tokens, producing a contextual state at…

Deep Learning for Natural Language: Transformers and Self-Supervised Learning
A Transformer specifies how token representations interact. A learning objective specifies what those interactions should help predict. Self-supervised learning connects the two by…
