Kerasis an Open Source Neural Network library written in Python that runs on top of Theano or Tensorflow. It is designed to be modular, fast and easy to use. It was developed by François Chollet, a Google engineer. Keras doesn’t handle low-level computation. Instead, it uses another l...
Fine-tuning involves adapting a pre-trained model to a new dataset by continuing its training. This can be beneficial as it allows the model to use the knowledge it has already acquired, reducing the time and resources required to train a model from scratch. This can be especially useful whe...
