Most of the other replies to you, except for the one by tempusalaria, are not really answering the question.

Broadly, while there was a lot of initial excitement - it simply does not seem like offline + off-policy RL can beat online + on-policy RL methods like PPO. Sampling trajectories from the actual model you are training and scoring them seems like it works much better in practice, never mind the additional flexibility methods like PPO provide over the form of the reward function.

What's _online_ RL for an LLM? Saw this on the llama 3.3 reports too...

You take the action which you computed to be optimal under the hypothetical of your posterior sample; this then yields a new observation. You add that to the dataset, and train a new NN.

ah, so observe the reward and then take a gradient step

if you have an NN that is probabilistic, how do you update the prior after sampling from the posterior?

ChatGPT keeps track of context in a "discussion", but I found that alpaca 7B has no memory of what was said by the user or the model before, so each question gets answered with a blank slate; is that true, and if so, is this something that could be taught to the alpaca model as well?

to add state (memory), u can either:

* inject the running chat log into the prompt * inject the summary of the chat into the prompt

What's the main criticism?
eggie5 · 3 years ago
I think the main criticism is portability of skills, ie everyone wishes ebay would just use react.

> Why should I question it. His error does me no injury

Isn't that an incredibly dangerous behavior especially in political debates ? I mean, wrong political opinions do injure people. Maybe not the other people in the room but the people who elected them.

Do I miss something ?

As Adams agreed, it was quite the perplexing philosophy. However, who won in the end? The firebrand Adams or stoic Jefferson???
