Foundational knowledge for deep learning includes a set of diverse components, because deep learning “combines diverse components such as ==linear algebra, calculus, probabilities, optimization, signal processing, programming, algorithmics, and high performance computing==.”[‌:cite[1]{ln=3}‌] Below is a practical way to organize those foundations into areas you should know. [‌:cite[1]{ln=3}‌] 1) Mathematical foundations (for models and training) Linear algebra (e.g., vectors/matrices and the operations used throughout models).[‌:cite[1]{ln=3}‌] Calculus (needed for understanding and working with gradient based methods used in training).[‌:cite[1]{ln=3}‌] Probability (the book lists “probabilities” as a core component combined with deep learning).[‌:cite[1]{ln=3}‌] Optimization (central because training is framed as minimizing a loss).[‌:cite[1]{ln=3}‌], [‌:cite[2]{ln=2}‌] 2) Machine learning foundations (learning from data, objective functions) Training is described as choosing parameters to minimize a loss : the “notion of goodness” is formalized with a loss, and “training the model consists of computing a value \(w^\ \) that minimizes” that loss.[‌:cite[2]{ln=1}‌], [‌:cite[2]{ln=2}‌] Models are treated as parametric computer code with trainable parameters \(w\), fit using data pairs \((x n,y n)\).[‌:cite[3]{ln=1}‌], [‌:cite[3]{ln=2}‌] 3) Core training mechanics (gradient based training, backprop) The book explicitly highlights gradient descent and backpropagation as core training topics (they appear as named subsections in the Foundations/Training chapter sequence).[‌:cite[4]{ln=3}‌] 4) Computing and implementation foundations (scalable, efficient execution) From an implementation standpoint, deep learning is “about executing heavy computations with large amounts of data.”[‌:cite[5]{ln=1}‌] High performance computing is one of the diverse components deep learning combines.[‌:cite[1]{ln=3}‌] GPU/TPU style parallel hardware matters because GPUs enabled such computations on affordable hardware, shaping what can be done efficiently.[‌:cite[5]{ln=2}‌], [‌:cite[6]{ln=1}‌] Tensors and tensor operations are foundational in practice because computations can be decomposed into elementary tensor operations to avoid non parallel loops and poor memory management.[‌:cite[7]{ln=3}‌] 5) Algorithmic foundations The book includes algorithmics among the diverse components that make deep learning complicated to learn.[‌:cite[1]{ln=3}‌]
