PyTorch is a deep learning framework that enables building neural networks with ease. It is an open-source machine learning library developed by Facebook's AI research team. Fastai is a high-level library built on top of PyTorch that makes it easier to train neural networks by providing a set of abstractions for common tasks, such as data loading, transformation, and model training.
Fastai provides pre-built models for various tasks like image classification, text classification, and tabular data analysis. It also includes a set of pre-processing functions to transform data to the desired format. Fastai also provides an easy-to-use API for training models, including callbacks for monitoring and adjusting the model during training.
One of the key features of Fastai is its approach to transfer learning. It enables developers to take pre-trained models and fine-tune them on their specific datasets, reducing the amount of training required and improving the accuracy of the model.
Overall, PyTorch and Fastai are powerful tools for building machine learning models, especially for deep learning tasks. They provide a high degree of flexibility in model design and training, making it easier to experiment and iterate quickly.
