Update: Our code for a new preprint improves the generation/data processing pipeline in this repository (as well as other things like support for greedy decoding and new baselines). Please check it out!

Quick Start

We provided a simple evaluation in notebook/demo.ipynb using 500 samples and the corresponding responses. Note that to get the automatic evaluation based on GPT, you would need to update keys.json with your API keys first.

Replicate Our Experiments

First, set the corresponding paths in _settings.py.

Generate the Responses

Use the llama-13b-hf, opt-13b or gpt-3.5-turbo for model, and coqa, triviaqa and nq_open for the dataset below. (You need to download the LLaMA weight first).

python -m pipeline.generate --model llama-13b-hf --dataset coqa

For gpt-3.5-turbo experiments, please update keys.json with your API keys first.

Update GEN_PATHS in _settings.py for next steps.

(You could find the exact generatoins we used in our paper here in "output".)

Run UQ Experiments

You can run dataeval/load.py to cache down results first. (We have uploaded the cache in persist_to_disk to this link in "persist_to_disk". Once you download the cache, you should be able to directly run dataeval/load.py without missing the cache.) I use persist_to_disk to cache experiment results (i.e. those @ptd.persistf decorators and ptd.manual_cache calls).

Then, please refer to notebook/main.ipynb for an example.

Reminder

As many may have noticed, gpt-3.5-turbo's performnace dropped a lot recently. All experiments in this manuscript were carried out (and could be replicated) using gpt-3.5-turbo-0301 instead of the latest version.
