AI & ML interests

We build tools to understand how models change during training, identify where regressions and unwanted behaviors emerge, localize meaningful changes within the model, and correct or remove learned behavior without full retraining.Our work spans training dynamics, model interpretability, machine unlearning, training-free model optimization, and AI governance.

Recover a Capability Lost During Fine-Tuning

Sequential fine-tuning quietly degraded a capability the model already had. Authentrics restores it — no retraining from scratch. • 1 item • Updated 22 days ago

Removing Memorized PII From a Fine-Tuned Model

A model fine-tuned on data containing PII memorized it. Authentrics locates and removes that influence — no retraining from scratch. • 1 item • Updated 22 days ago

Reading How a Mixture-of-Experts Model Routes Its Inputs

Reading how Mixtral-8x7B routes activations, and how that structure emerges across training — without moving weights off your hardware. • 1 item • Updated 22 days ago

Diagnosing What Changed Across a Model's Training Run

Tracking parameter and activation drift across the NVIDIA Nemotron Cascade 8B checkpoint lineage to see what changed, where, and when. • 1 item • Updated 22 days ago

Finding and Removing a Neural Network Backdoor

A BadNets backdoor is planted in one MNIST training epoch, localized via checkpoint drift, and removed with Authentrics — no retraining from scratch. • 2 items • Updated 22 days ago
