In thi segment we analyse the relation between AI and neuroscience, learn how to build simple neural networks with code examples, and discover how these fields drive mutual progress.
The interplay between artificial intelligence (AI) and neuroscience has created a virtuous circle of innovation, where insights from one field accelerate progress in the other. For instance, neuroscience helps validate AI algorithms by showing how artificial models mimic biological processes, suggesting these methods are on the right track. Conversely, AI provides tools to simulate and analyze complex brain functions, advancing our understanding of cognition and perception.

In theory, neural networks try as best to replicate the functioning of actual neurons. Below is a minimal implementation of a perceptron, the simplest neural network model.
import numpy as np
# Define a perceptron function
def perceptron(input1, input2, output):
# Initialize weights and bias
weights = np.random.rand(3)
learning_rate = 0.1
epochs = 100
for _ in range(epochs):
# Forward pass
weighted_sum = input1 * weights[0] + input2 * weights[1] + 1 * weights[2]
prediction = 1 if weighted_sum >= 0 else 0
# Update weights
error = output - prediction
weights[0] += learning_rate * error * input1
weights[1] += learning_rate * error * input2
weights[2] += learning_rate * error * 1 # Bias update
return weights
# Train the perceptron to learn the AND gate
trained_weights = perceptron(1, 1, 1) # Input 1, Input 2, Expected Output
print("Trained Weights:", trained_weights)
