Introduction to Reinforcement learning
Large Language Models (LLMs) however nascent have changed the way the white collar and creative workflows are structured. From drafting documents and emails to generating reports and even automating customer service, and summarizing large text data, LLMs have significantly increased efficiency in the workplace. However, as with any technology, there are challenges. Often, the inferences generated by LLMs do not meet user expectations. This could be due to misinterpretation of the user's input, insufficient training data, or biases in the model's predictions.
To overcome these challenges, some of the methods are being used are
Fine-Tuning: By training the models on specific domain-related data, we can fine-tune them to understand and generate better responses in that domain. This can be particularly beneficial in specialized fields such as law, medicine, and research where terminology and context can be complex.
Active Learning: This involves iteratively training the model, and using its predictions to generate new training examples. The idea is to let the model learn from its mistakes and improve over time.
Bias Mitigation Techniques: Several bias mitigation techniques are being developed to address the issue of bias in AI models. These include pre-processing methods to remove bias from the training data, in-processing methods to modify the learning algorithm, and post-processing methods to adjust the model's predictions.
Explainability and Transparency: By making the AI models more explainable and transparent, we can better understand why they make certain predictions. This can help the larger AI community in identifying and correcting errors in the model's reasoning.
Reinforcement Learning from Human Feedback (RLHF): RLHF is a powerful tool to align AI models with complex human values. Using human feedback as a measure of performance or as a loss function to optimize the model, can significantly improve the quality of inferences. The range of feedback that can be captured here can be from preferential responses to detailed feedback.
