Keras
Definition
Keras is an open-source software library that provides a Python interface for artificial neural networks. Keras acts as an interface for the TensorFlow library. It is designed to enable fast experimentation with deep neural networks, focusing on being user-friendly, modular, and extensible.
Why It Matters
Keras dramatically simplifies the process of building and training neural networks. Its high-level, user-friendly API allows developers to create complex models with just a few lines of code, making deep learning more accessible.
Contextual Example
To build a simple image classifier, a developer using Keras can stack layers like building blocks: `model.add(Conv2D(...)); model.add(MaxPooling2D(...)); model.add(Dense(...))`.
Common Misunderstandings
- Keras is not a standalone framework; it is a high-level API that runs on top of a backend like TensorFlow.
- It is now officially part of the core TensorFlow project.
