"In this notebook, you will fine-tune a FLAN-T5 model to generate less toxic content with Meta AI's hate speech reward model. The reward model is a binary classifier that predicts either \"not hate\" or \"hate\" for the given text. You will use Proximal Policy Optimization (PPO) to fine-tune and reduce the model's toxicity."

"### 2.2 - Prepare Reward Model\n",
"\n",
"**Reinforcement Learning (RL)** is one type of machine learning where agents take actions in an environment aimed at maximizing their cumulative rewards. The agent's behavior is defined by the **policy**. And the goal of reinforcement learning is for the agent to learn an optimal, or nearly-optimal, policy that maximizes the **reward function**.\n",
"\n",
"In the [previous section](#2.1) the original policy is based on the instruct PEFT model - this is the LLM before detoxification. Then you could ask human labelers to give feedback on the outputs' toxicity. However, it can be expensive to use them for the entire fine-tuning process. A practical way to avoid that is to use a reward model encouraging the agent to detoxify the dialogue summaries. The intuitive approach would be to do some form of sentiment analysis across two classes (`nothate` and `hate`) and give a higher reward if there is higher a chance of getting class `nothate` as an output.\n",
"\n",
"For example, we can mention that having human labelers for the entire finetuning process can be expensive. A practical way to avoid that is to use a reward model.\n",
"\n",
"use feedback generated by a model\n",
"\n",
"You will use [Meta AI's RoBERTa-based hate speech model](https://huggingface.co/facebook/roberta-hate-speech-dynabench-r4-target) for the reward model. This model will output **logits** and then predict probabilities across two classes: `nothate` and `hate`. The logits of the output `nothate` will be taken as a positive reward. Then, the model will be fine-tuned with PPO using those reward values.\n",
"\n",
"Create the instance of the required model class for the RoBERTa model. You also need to load a tokenizer to test the model. Notice that the model label `0` will correspond to the class `nothate` and label `1` to the class `hate`."

"### 2.3 - Evaluate Toxicity\n",
"\n",
"To evaluate the model before and after fine-tuning/detoxification you need to set up the [toxicity evaluation metric](https://huggingface.co/spaces/evaluate-measurement/toxicity). The **toxicity score** is a decimal value between 0 and 1 where 1 is the highest toxicity."
