为了适应下游任务,GPT-1模型需要对其网络结构进行一些修改,如图3-2的微调部分。假设有一个带有标签的数据集C,其中,词的序列为 u_1,u_2,...,u_m ,标签为 y。词序列首先输入到预训练好的GPT-1模型中,经过最后一层Transformer后得到输出 \bm{h}_l ,然后输入到下游任务的线性层中,得到最终的预测输出,...
ChatGPT API Moderation model OpenAI API provides the possibility to classify any text to ensure it complies with their usage policies, using a binary classification. This classification is integrated in their Moderation model that one can call using openai API in Python. 7 categories are used in ...
Train the model: We will use a Random Forest classifier, which is a powerful and versatile machine learning model that often performs well out of the box. Evaluate the model: We will evaluate the model's performance on the test set using appropriate metrics for binary classification problems, ...
