devinterp 1.2.0

A library for doing research on developmental interpretability

DevInterp

A Python Library for Developmental Interpretability Research

DevInterp is a python library for conducting research on developmental interpretability, a novel AI safety research agenda rooted in Singular Learning Theory (SLT). DevInterp proposes tools for detecting, locating, and ultimately controlling the development of structure over training.

:warning: This library is still in early development. Don't expect things to work on a first attempt. We are actively working on improving the library and adding new features.

Installation

To install devinterp, simply run pip install devinterp. (Note: This has PyTorch as a dependency.)

Minimal Example

from devinterp.slt.sampler import  sample, LLCEstimator
from devinterp.optim import SGLD
from devinterp.utils import default_nbeta

# Assuming you have a PyTorch Model assigned to model, and DataLoader assigned to trainloader
llc_estimator = LLCEstimator(..., nbeta=default_nbeta(trainloader))
sample(model, trainloader, ..., callbacks = [llc_estimator])

llc_mean = llc_estimator.get_results()["llc/mean"]

Advanced Usage

To see DevInterp in action, check out our example notebooks:

• Introduction
• Normal Crossing Demo
• Grokking Demo

For more advanced usage, see the Diagnostics notebook and for a quick guide on picking hyperparameters, see the above Grokking Demo or the the Calibration notebook. . Documentation can be found here.

Known Issues

• LLC Estimation is currently more of an art than a science. It will take some time and pain to get it work reliably.

If you run into issues not mentioned here, please first check the github issues, then ask in the DevInterp Discord, and only then make a new github issue.
