Key Features of Keras

The popularity of Keras stems from its design, which strikes a balance between ease of use and flexibility. It allows users to experiment quickly while still being powerful enough for complex tasks. 

Developers prefer Keras because its clear syntax reduces development time and helps focus on building models rather than handling technical complications. These qualities have made Keras one of the leading tools in artificial intelligence projects worldwide.

Here are some key features of Keras:

• User-friendly API – Easy to learn and reduces coding complexity.
• Modular design – Models can be created by stacking and connecting layers.
• Multiple backends – Works with TensorFlow and supports CPU or GPU processing.
• Large community support – Extensive documentation and shared resources.

Components of Keras

Keras has several building blocks that enable the design and training of machine learning models. These components work together to define the model structure, train it, and evaluate its performance. 

By combining these elements, you can create anything from simple feedforward networks to advanced deep learning architectures used in computer vision and natural language processing.

The main components of Keras are:

• Models – Define how the network is structured.
• Layers – Include Dense, Convolutional, and Recurrent options.
• Optimisers – Algorithms like Adam and RMSprop improve model training.
• Loss functions – Measure the accuracy of predictions.
• Metrics – Help evaluate the performance of a model.
