Eigenvectors and Eigenfaces
2025-12-08 applications basics image math theory video Introduction to eigenvectors, which abstract the concept of an "axis" along or around which one might scale or rotate things. Illustrated by a 1991 paper on "eigenfaces," which applies this concept to recognizing faces in images. Access: $ Basic
Vision Transformers
2025-12-01 AIAYN BERT attention basics image What if we applied the "attention is all you need" architecture to images instead of language? That's the question considered in this paper from 2021, which laid the groundwork for today's multi-modal models. Access: $ Basic
Latent Diffusion
2025-08-25 model-intro image diffusion The highly abstract "diffusion" model concept gets one more significant development: wrapping the model inside an autoencoder that translates between the high-dimensional pixel space and a lower-dimensional latent space with semantic properties. Running a diffusion model inside the latent space has theoretical and practical advantages, and the authors of the paper apply that to a range of image-generation problems. Access: $$$ Pro
Original diffusion: Adding noise to remove it
2025-08-04 theory image diffusion Some of the underlying theory for diffusion-type models, which have become popular for image generation. This paper is one of the original sources for the diffusion approach, not introduction of a specific model but the very general abstract concepts used in subsequent models.

Features are not what you think
2025-08-01 theory security image Two interesting things about neural network image classifiers: one, the individual neurons don't seem to be special in terms of detecting meaningful features; and two, it's frighteningly easy to construct adversarial examples that will fool the classification.
