fine-tuning and in-context learning
Pre-training, fine-tuning and in-context learning in Large Language Models (LLMs)
Since the advent of Transformers in 2017, Large Language Models (LLMs) have completely changed the process of training ML models for language tasks. Earlier, for a given task and a given dataset, we used to play around with various models like RNNs, LSTMs, Decision Trees, etc by training each of them on a subset of the data and testing on the rest. And whichever model gave the best accuracy was chosen as the winner. Of course, a lot of model hyper-parameters also needed to be tuned and experimented with. And for many problems, feature engineering was also necessary.
