How models can adapt at inference time, what is learned during that process, and which trade-offs make adaptation reliable.
Serendeep Rudraraju / M.Sc. computer science
Test-time adaptation, interpretability, and long-context models.
I document independent study through technical writing, reproducible software, and structured reading notes.

Independent study
Research questions I am currently working through.
My current process is literature mapping, technical writing, and small implementations. These are study topics, not claims of completed research results.
Methods for understanding internal model behavior, connecting mechanisms to outputs, and separating useful evidence from plausible stories.
