Pre-training tasks
Pre-training tasks are fundamental for developing universal language representations. After a model undergoes pre-training, various techniques are employed to adapt it for specific downstream applications. The pre-training tasks themselves are generally classified into three main types:
- Supervised learning: Training on data with explicit input-output pairs.
- Unsupervised learning: Discovering inherent knowledge from unlabeled data, such as through probabilistic language modeling.
- Self-Supervised learning: A hybrid approach where supervision signals are automatically generated from the data itself, as seen in masked language modeling (MLM).

A small biotech company wants to build an AI model to classify protein sequences for a very specific function. They have a high-quality, but small, labeled dataset of 10,000 sequences. They have limited computational resources and a tight deadline. Which of the following strategies represents the most effective and efficient approach for them to develop a high-performing model?

A research team is developing a new language model and is considering different pre-training approaches. Match each pre-training scenario below with the correct category of learning it represents.
A language model is being trained on a large corpus of text from the internet. The training process involves randomly hiding 15% of the words in each sentence and then tasking the model with predicting the original identity of these hidden words based on the surrounding context. Which category of pre-training task does this scenario best exemplify, and why?
