OpenAI’s approach to Q-Learning has been drawing significant attention recently.
However, there’s a fundamental issue in the way Q-learning is typically implemented in deep learning and neural network environments. This concern is highlighted in the award-winning paper “Non-delusional Q-learning,” presented at NeurIPS.
The paper suggests a fundamental flaw in the blind application of Q-learning updates to deep neural networks. It points out that such updates can create a self-contradictory scenario where improving the network for the current batch of data inadvertently makes it less effective for other batches. This is akin to a situation in supervised learning where optimizing a network for a specific set of data may degrade its performance on other datasets.

I’m curious about others’ views on this topic. What do you think about the implications of these findings for the future of Q-learning in deep learning environments?
We don’t even know whether it’s actually an RL approach lol
it’s very likely something like this: https://arxiv.org/pdf/2305.18290.pdf
Or finetuning on high quality datasets
what is the basis on which you judge it “very likely”. The only information is a leaked rumor that there is something with the name “Q*”. How do we get from that to DPO?
