What is Multitask Learning?
Multitask learning is a machine learning approach where a single model is trained to perform multiple tasks simultaneously. The idea behind multitask learning is that the model can leverage shared knowledge and representations across tasks, leading to better generalization and improved performance on individual tasks.
Benefits of Multitask Learning
Improved generalization: By learning multiple tasks, the model can gain a more comprehensive understanding of the data, reducing the risk of overfitting and improving generalization.
Efficient training: Training a single model for multiple tasks can be more efficient than training separate models for each task.
Knowledge transfer: Learning multiple tasks can help the model transfer knowledge from one task to another, improving performance on related tasks.
Examples of Multitask Learning in NLP
BERT (Bidirectional Encoder Representations from Transformers): A pre-trained language model that can be fine-tuned for various NLP tasks, such as sentiment analysis, named entity recognition, and question answering.
T5 (Text-to-Text Transfer Transformer): A pre-trained language model designed for multitask learning by casting all NLP tasks as text-to-text problems, enabling the model to perform tasks like translation, summarization, and classification.
