My own experiments with DLK
Experiments Conducted in Discovering Latent Knowledge:
- [x] use pytorch lightning
- [x] batch hidden states 5x faster
- [x] use llama 13B, to see if larger models give better results
- [x] eval on some deceptive or misleading statements
- [x] debug by looking at model output
- [x] try ranking hidden state (on a branch)
- [x] try a tokenized autoencoder (on a branch)
- [x] try a sparse autoencoder (on a branch)
- Implemented PyTorch Lightning
- Batched hidden states for 5x speed improvement
- Utilized llama 13B to investigate if larger models yield better results
- Evaluated on various deceptive or misleading statements
- Debugged by examining model output
- Tested ranking of hidden state (on a separate branch)
- Experimented with a tokenized autoencoder (on a different branch)
- Explored a sparse autoencoder (on another branch)
I'm afraid none of these approaches have got the >90% out of distribution results I hope for. I beleive this to be because current models are too small to have internals that reliably produce deception.
Unfortunately, none of these approaches have achieved the desired >90% out-of-distribution results. The current hypothesis is that existing models are too small to possess internal structures that can reliably detect deception.
