**The Microsoft AI For Beginners repository contains over 50 executable hands-on projects spanning symbolic AI, neural networks, computer vision, natural language processing, reinforcement learning, genetic algorithms, and AI ethics, with each notebook offering parallel implementations in both PyTorch and TensorFlow.**

The microsoft/AI-For-Beginners curriculum is structured as a comprehensive, beginner-friendly journey through artificial intelligence fundamentals. Unlike theoretical courses, this repository delivers practical, self-contained projects primarily as Jupyter notebooks that learners can execute immediately. Each module builds upon the previous, progressing from classical symbolic reasoning to state-of-the-art multimodal AI systems.

## Symbolic AI and Expert Systems

The curriculum begins with classical AI approaches before diving into modern deep learning. The **Symbolic AI** module covers knowledge representation, expert-system reasoning, and ontology building.

- **`lessons/2-Symbolic/Animals.ipynb`** – Implements a rule-based expert system that classifies animals through logical inference, demonstrating how early AI systems encoded domain knowledge without machine learning.

## Neural Networks and Deep Learning Fundamentals

The repository provides extensive coverage of neural network foundations, from single-layer perceptrons to multi-layer architectures.

- **`lessons/3-NeuralNetworks/03-Perceptron/Perceptron.ipynb`** – Interactive visualization of the perceptron learning algorithm and its limitations on linearly separable data.
- **`lessons/3-NeuralNetworks/`** – Contains notebooks demonstrating overfitting patterns, activation functions, and framework basics for both **PyTorch** and **TensorFlow/Keras**.

## Computer Vision Projects

The Computer Vision module (`lessons/4-ComputerVision/`) offers the most diverse project collection, covering everything from traditional OpenCV operations to generative models.

- **`lessons/4-ComputerVision/07-ConvNets/ConvNetsPyTorch.ipynb`** – Complete CNN implementation for image classification using convolutional and pooling layers.

## Dual-Framework Implementation Strategy

Every major project in the AI For Beginners repository provides **parallel implementations** in the two most widely-used deep learning frameworks. When you open a lesson folder, you typically find:
- `LessonNamePyTorch.ipynb` – Native PyTorch implementation using `torch.nn` modules
- `LessonNameTensorFlow.ipynb` – Equivalent TensorFlow/Keras implementation using `tf.keras` layers

This approach allows learners to compare framework syntax while understanding that underlying algorithms remain consistent across platforms.

## Code Examples from the Repository

Below are executable snippets demonstrating the project's structure and coding standards. These examples reference the [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) dependencies and can be run after setting up the Conda environment.

### TensorFlow CNN for Image Classification

This example from the computer vision module demonstrates a convolutional neural network for CIFAR-10 classification:

```python
import tensorflow as tf
from tensorflow.keras import layers, models
import matplotlib.pyplot as plt

# Load the CIFAR-10 dataset (built-in)

(x_train, y_train), (x_test, y_test) = tf.keras.datasets.cifar10.load_data()
x_train, x_test = x_train / 255.0, x_test / 255.0

# Define a small ConvNet

model = models.Sequential([
    layers.Conv2D(32, (3,3), activation='relu', input_shape=(32,32,3)),
    layers.MaxPooling2D((2,2)),
    layers.Conv2D(64, (3,3), activation='relu'),
    layers.MaxPooling2D((2,2)),
    layers.Flatten(),
    layers.Dense(64, activation='relu'),
    layers.Dense(10, activation='softmax')
])

model.compile(optimizer='adam',
              loss='sparse_categorical_crossentropy',
              metrics=['accuracy'])

model.fit(x_train, y_train, epochs=10, validation_data=(x_test, y_test))

```

### PyTorch Reinforcement Learning

This snippet from `lessons/6-Other/22-DeepRL/CartPole-RL-PyTorch.ipynb` implements a policy gradient method for the CartPole environment:

```python
import gym, torch, torch.nn as nn, torch.optim as optim

env = gym.make('CartPole-v1')
obs_size = env.observation_space.shape[0]
n_actions = env.action_space.n

class Policy(nn.Module):
    def __init__(self):
        super().__init__()
        self.net = nn.Sequential(
            nn.Linear(obs_size, 128), nn.ReLU(),
            nn.Linear(128, n_actions), nn.Softmax(dim=-1)
        )
    def forward(self, x): return self.net(x)

policy = Policy()
optimizer = optim.Adam(policy.parameters(), lr=1e-2)

def select_action(state):
    probs = policy(torch.from_numpy(state).float())
    action = torch.multinomial(probs, 1).item()
    return action, probs[action]

for episode in range(200):
    state = env.reset()
    log_probs, rewards = [], []
    done = False
    while not done:
        action, prob = select_action(state)
        next_state, reward, done, _ = env.step(action)
        log_probs.append(torch.log(prob))
        rewards.append(reward)
        state = next_state
    # Simple policy-gradient update

    loss = -torch.stack(log_probs).sum() * sum(rewards)
    optimizer.zero_grad()
    loss.backward()
    optimizer.step()

```
