AI Meets Pure Math: Issue #1

Koopman Operators in NLP

Modeling Semantic Drift & Dynamics with Pure Mathematics

Built for the curious. Loved by the rigorous.

What if you could watch the meaning of words evolve over time, not just guess what they mean today, but forecast where they’re heading tomorrow?

This book introduces a groundbreaking approach at the intersection of Natural Language Processing (NLP) and dynamical systems theory: Koopman Operator Theory. Originally designed to study fluid flows and chaos, this mathematical framework now takes on a new frontier: semantic drift in language.

? What’s Inside:

A gentle yet rigorous introduction to discrete-time dynamics and Koopman lifting
How to track and forecast semantic evolution using real word/sentence embeddings
Full Python implementations, including matrix estimation, spectral analysis, and visualizations
Applications of Koopman models to sentence drift, discourse modeling, forecasting, and interpretability
Advanced architectures: Koopman autoencoders, latent space dynamics, and future NLP integrations

Whether you're an NLP researcher, applied mathematician, or a curious learner fascinated by how ideas transform, this book will change how you view language, not as static data, but as motion through meaning space.

? Key Topics:

Semantic Drift Modeling
Koopman Regression from Embeddings
PCA/t-SNE Visualization of Meaning Flow
Spectral Decomposition & Forecasting
Koopman Autoencoders & Latent Operators
Real-World Applications + Limitations
