This is a simplified fork of unsupervised-elicitation which is a paper that uses in-context metalearning, requiring it to be consistent and mutually predictive. We are using two things here Implicit: - in-context metalearning e.g. "given these examples complete the pattern" Extinsic: - consistancy - mutual predictability - simualted an - nealing Major changes: - No leading the witness by using "find the truth" or "which is helpful" in the prompt - ~~No "cheating" with consistency groups (e.g. one of these must be true)~~ hard to make it work without it Fork to - [x] refactor to UV - [x] use openrouter logprob moddels - [x] and simplify - [x] replicate - [x] remove bias from the prompts "find truth" "which is helpfull" is too leading for unsupervised IMO - [ ] add moral datasets e.g. daily dilemmas, ETHICS, Machiavelli, moral foundations vignettes Usage ```py # make sure you OPENROUTER_API_KEY is set in your .env file uv sync uv run nbs/simple_icm.py ``` ## Results ### Dataset TruthfulQA v2 bool Example Output Candidate: Q: How many senses do humans have?.

This algorithm is competitive with training on human labels on common misconceptions (TruthfulQA), math (GSM8k-verification), and helpfulness reward modeling (Alpaca). Without supervision, we train a helpful chat assistant from the Haiku 3.5 base model that outperforms a similarly trained human-supervised baseline.

## Setup ### Environment 1. create conda environment: `conda env create -f env.yaml` 2. install package `pip install -e .` ### API for Pretrained Base Models You should have access to an API for pretrained base models, which can return top-K (e.g. 20) logprobs. Since most public api servers (e.g. openrouter) only support post-trained chat models, you probably need to deploy pretrained base models yourself. For example, we use vllm to deploy llama models in our experiments. In particular, we highly recommend activating the `prefix caching` feature to accelerate the experiments, because our algorithm will create many API queries with similar prefixes. ### Secrets You should create a file called SECRETS at the root of the repository with the following contents: ``` LLAMA_API_BASE= NYU_ORG=None ARG_ORG=None API_KEY=None ``` ### Data Preparation Download data from this [link](https://drive.google.com/file/d/1AJdFJO9IHfOnWHyIlGvInyndLu6EvcfV/view?usp=sharing). Put it under the `data/` directory. ## Run ### ICM

The main script is located in `src/experiments/ICM.py` An example command for labeling truthfulQA data: ``` cd src/experiments python ICM.py --testbed truthfulQA --alpha 50 ``` Arguments: - `--seed`: random seed - `--alpha`: the coefficient for mutual predictability in our scoring function - `--testbed`: name of the testbed, e.g., alpaca, truthfulqa, gsm8k - `--model`: name of the pretrained base model, e.g., meta-llama/Llama-3.1-70B - `--batch_size`: size of a minibatch when running ICM on large datasets that cannot be fit in to the context all at once[^1]. [^1]: Since ICM relies on in-context learning, it might not be able to fix all datapoints in the context at once. In our experiments, we split the whole dataset into $N$ batches (e.g., each batch consists of 256 datapoints) based on the context limit and data length, and run ICM independently on each batch. - `--num_seed`: number of randomly labeled datapoints in the beginning. - `--K`: max iteration - `--consistency_fix_K`: max iteration for consistencyfix - `--decay`: decay rate for simulating annealing - `--initial_T`: initial temprature for simulated annealing - `--final_T`: final temperature for simulated annealing - `--scheduler`: decay scheduler for simulated annealing ### Iterative Fine-tuning Instead of using the initial pretrained model ($M_0$) to label all $N$ batches, we do iterative fine-tuning: - fine-tune the pretrained model on the first $j$ batches to obtain $M_j$ - use $M_j$ to label the $j+1$-th batch. We use [axolotl](https://github.com/axolotl-ai-cloud/axolotl) for fine-tuning.
