How Does Keras Work?
Here is a detailed point-wise overview of how Keras works:
High-Level Building Blocks
Keras provides intuitive abstractions for the key components of neural networks like layers, models, optimizers, and losses. This allows you to quickly build models with just a few lines of Python code.
Configuration via Python
Models can be configured directly in Python instead of through lengthy configuration files. This is more concise and reduces errors.
Automatic Heavy Lifting
Keras handles lower level tensor manipulation and computation under the hood. This frees you to focus on the machine learning problem.
Reusable Parts
Common building blocks like convolutional layers or RNNs can be reused across models. This accelerates prototyping.
Customizable Training
Callbacks provide extensibility to customize training loops beyond the built-in fit method.
Extendable Architecture
Keras provides interfaces to extend it for new layers, losses etc. This facilitates creating innovative architectures.
TensorFlow/PyTorch Integration
Keras seamlessly integrates with TensorFlow or PyTorch backends. This provides flexibility to use either framework.
End-to-End Workflow
The intuitive abstractions cover the full deep learning workflow from configuring models to training to deployment.
Getting Started with Keras
Keras makes implementing deep learning highly accessible for data scientists. To begin, install Keras and its dependencies like TensorFlow using pip. Keras offers a sequential API ideal for most models:
```python
from keras.models import Sequential
model = Sequential()
```
Next, add layers specifying the number of hidden units. Convolutional layers excel for image data, recurrent layers for sequence data:
```python
from keras.layers import Dense
model.add(Dense(64, activation='relu', input_shape=(32,)))
model.add(Dense(10, activation='softmax'))
```
Compile the model with loss and optimizer functions:
```python
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
```
Now fit the model to training data in numpy arrays:
```python
model.fit(x_train, y_train, batch_size=32, epochs=5)
```
Evaluate on test data and make predictions:
```python
test_loss, test_acc = model.evaluate(x_test, y_test)
y_pred = model.predict(x_new)
```
That covers the basics - Keras puts the power of deep learning and neural networks into any Python developer’s hands.
