2. Setting Up a Basic Neural Network with Theano

Let’s start by setting up a simple neural network using Theano. This network will have an input layer, one hidden layer, and an output layer.

Step 1: Import Required Libraries

import theano
import theano.tensor as T
import numpy as np

Step 2: Define the Network Structure

Here, we’ll define the input, weights, and biases for our neural network.

# Define input and output variables
X = T.dmatrix('X')
y = T.dmatrix('y')

# Define weights and biases
W1 = theano.shared(np.random.randn(3, 4), name='W1')
b1 = theano.shared(np.random.randn(4), name='b1')
W2 = theano.shared(np.random.randn(4, 1), name='W2')
b2 = theano.shared(np.random.randn(1), name='b2')

Step 3: Construct the Neural Network

# Define the hidden layer
hidden_layer = T.nnet.sigmoid(T.dot(X, W1) + b1)

# Define the output layer
output_layer = T.nnet.sigmoid(T.dot(hidden_layer, W2) + b2)

Step 4: Define the Cost Function

The cost function will measure how well our neural network performs. We’ll use the Mean Squared Error (MSE) for this purpose.

cost = T.mean(T.square(output_layer - y))

Step 5: Backpropagation

We need to compute the gradients of the cost function with respect to the weights and biases. Theano’s automatic differentiation makes this easy:

gradients = T.grad(cost, [W1, b1, W2, b2])
updates = [(W1, W1 - 0.01 * gradients[0]),
           (b1, b1 - 0.01 * gradients[1]),
           (W2, W2 - 0.01 * gradients[2]),
           (b2, b2 - 0.01 * gradients[3])]

Step 6: Compile the Training Function

The training function will update the weights and biases based on the gradients computed during backpropagation.

train = theano.function(inputs=[X, y], outputs=cost, updates=updates)

3. Training the Neural Network

To train our neural network, we’ll pass the training data through the network multiple times (epochs) and update the weights and biases accordingly.

Example Training Loop:

# Dummy training data
X_train = np.array([[0, 0, 1],
                    [1, 0, 0],
                    [0, 1, 1],
                    [1, 1, 0]])
y_train = np.array([[0], [1], [1], [0]])

# Train the network
for epoch in range(1000):
    cost_value = train(X_train, y_train)
    if epoch % 100 == 0:
        print(f'Epoch {epoch}, Cost: {cost_value}')

In this example, we train the network for 1000 epochs. Every 100 epochs, we print the cost to monitor the training process.

4. Evaluating the Model

After training, you can evaluate the model by using the trained weights and biases to make predictions on new data.

Prediction Function:

predict = theano.function(inputs=[X], outputs=output_layer)

# Predict on new data
new_data = np.array([[0, 1, 0]])
prediction = predict(new_data)
print(f'Prediction: {prediction}')

5. Conclusion

Using Theano for neural network implementation provides a deep understanding of the mechanics behind neural networks. While modern frameworks like TensorFlow and PyTorch offer higher-level abstractions, Theano’s symbolic approach is excellent for learning and building custom models from scratch.

By following this tutorial, you should now have a solid understanding of how to use Theano for neural network construction and training. Keep experimenting with different architectures and datasets to enhance your skills further.
