Frequently Asked Questions about Keras
What is Keras?
Keras is an open-source, high-level deep learning API written in Python. It provides a user-friendly interface for building and training neural networks, running on top of TensorFlow, Theano, or CNTK backends.
What are the primary use cases for Keras?
Image classification and object detection. Natural language processing (NLP). Reinforcement learning prototypes. Time series forecasting. Educational purposes and research experiments
What are the strengths of Keras?
Easy to learn and use. Rapid prototyping of deep learning models. Highly modular and extensible. Strong community and documentation. Backend-agnostic (primarily TensorFlow)
What are the limitations of Keras?
Less control for low-level custom operations compared to raw TensorFlow. Primarily Python-based. Not ideal for highly optimized production pipelines without TensorFlow knowledge. Limited support for non-TensorFlow backends in recent versions. Scaling very large models requires careful backend management
