Value Function Approximation

Value function approximation replaces a huge table of values with a small set of parameters that can generalize across similar states.

Manifold Learning

Manifold learning assumes high-dimensional data actually lies near a much lower-dimensional, smoothly curved surface embedded in a higher-dimensional space.

Neural Collapse

Neural Collapse describes what happens at the end of training: the penultimate-layer features of each class concentrate tightly around a class mean.

Metric Learning

Metric learning is about automatically learning a distance function so that similar items are close and dissimilar items are far in a feature space.

Transfer Learning Theory

Transfer learning theory studies when and why a model trained on a source distribution will work on a different target distribution.

Disentangled Representations

Disentangled representations aim to encode independent factors of variation (like shape, size, or color) into separate coordinates of a latent vector.

Self-Supervised Learning Theory

Self-supervised learning (SSL) teaches models to learn useful representations from unlabeled data by solving proxy tasks created directly from the data.

Contrastive Learning

Contrastive learning teaches models by pulling together similar examples (positives) and pushing apart dissimilar ones (negatives).

Embedding Spaces & Distributed Representations

Embedding spaces map discrete things like words or products to dense vectors so that similar items are close together.

Classifier-Free Guidance

Classifier-Free Guidance (CFG) steers diffusion sampling toward a condition (like a text prompt) without needing a separate classifier.

Energy-Based Models (EBM)

Energy-Based Models (EBMs) define probabilities through an energy landscape: low energy means high probability, with p(x) = exp(-E(x)) / Z.

Flow Matching

Flow matching learns a time-dependent vector field v_t(x, c) whose ODE transports simple noise to complex data, enabling fast, deterministic sampling.
