Keras Neural Networks: A Comprehensive Guide
🧠 Introduction to Keras
Keras is an open-source deep learning framework that simplifies building and training neural networks. It runs on top of TensorFlow, Theano, or CNTK, making it highly flexible for various machine learning tasks.
🔧 Key Features
- User-Friendly API: Easy to prototype and experiment with models
- Modular Architecture: Stack layers like building blocks
- Prebuilt Layers: Dense, Conv2D, LSTM, and more
- Support for Both CNNs and RNNs: Handles image and sequence data
📊 Getting Started
- Install Keras:
pip install keras
- Import libraries:
from keras.models import Sequential from keras.layers import Dense
- Build a simple network:
model = Sequential() model.add(Dense(32, activation='relu', input_dim=100)) model.add(Dense(1, activation='softmax')) model.compile(optimizer='adam', loss='binary_crossentropy')

💡 Tips for Effective Model Training
- Use
model.summary()
to visualize the network structure - Experiment with different activation functions (ReLU, Tanh, etc.)
- Regularly save checkpoints with
model.save()
