Core Concepts of AI

Core AI concepts provide the fundamental building blocks for developing intelligent systems, which are essential for any AI practitioner.

1. Introduction to AI

Artificial Intelligence (AI) involves creating algorithms that allow computers to perform tasks that typically require human intelligence. Key areas include natural language processing, image recognition, and decision-making systems.

2. Supervised Learning

Supervised learning is a type of machine learning where models are trained using labeled data. The goal is to learn a mapping from inputs to outputs based on example input-output pairs.

Common algorithms include:

Example of supervised learning with linear regression:


from sklearn.linear_model import LinearRegression

# Sample data
X = [[1], [2], [3], [4]]
y = [1, 2, 3, 4]

# Create and train the model
model = LinearRegression()
model.fit(X, y)

# Predicting a value
prediction = model.predict([[5]])
print(prediction)  # Outputs: [5.]

    

3. Unsupervised Learning

Unsupervised learning involves training models on data without labeled responses. The goal is to discover underlying patterns or groupings in the data.

Common algorithms include:

Example of K-Means clustering:


from sklearn.cluster import KMeans
import numpy as np

# Sample data
X = np.array([[1, 2], [1, 4], [1, 0], [4, 2], [4, 4], [4, 0]])

# Create and fit the model
kmeans = KMeans(n_clusters=2)
kmeans.fit(X)

# Predicting cluster for new data
prediction = kmeans.predict([[0, 0]])
print(prediction)  # Outputs: [1] (indicating which cluster it belongs to)

    

4. Reinforcement Learning

Reinforcement learning is a type of machine learning where an agent learns to make decisions by taking actions in an environment to maximize cumulative reward.

Key concepts include:

Example of reinforcement learning with Q-learning:


import numpy as np

# Q-learning parameters
Q = np.zeros((state_space_size, action_space_size))
learning_rate = 0.1
discount_factor = 0.9

# Example update rule
# Assume state and action are given
Q[state, action] += learning_rate * (reward + discount_factor * np.max(Q[next_state]) - Q[state, action])

Policy and Value Iteration are iterative algorithms used to find optimal policies in MDPs. These algorithms update value functions and policies until convergence.

    
    // Pseudocode for Value Iteration
    Initialize V(s) arbitrarily
    Repeat until convergence:
        For each state s:
            V(s) = max_a ( R(s, a) + γ * Σ P(s'|s, a) * V(s') )
    
    

4. Q-Learning

Q-Learning is a model-free reinforcement learning algorithm that learns the value of actions in states. It uses the Q-value to update action preferences based on received rewards.

    
    Q(s, a) ← Q(s, a) + α [ R(s, a) + γ max_a' Q(s', a') - Q(s, a) ]
    
    

5. Sarsa

Sarsa (State-Action-Reward-State-Action) is an on-policy reinforcement learning algorithm that updates Q-values based on the action taken by the current policy.

    
    Q(s, a) ← Q(s, a) + α [ R(s, a) + γ Q(s', a') - Q(s, a) ]
    
    

6. Deep Q Networks

Deep Q Networks (DQNs) leverage deep learning techniques to approximate Q-values, enabling reinforcement learning to be applied to complex environments with high-dimensional state spaces.

    
// Pseudocode for DQN training
Initialize replay buffer and neural network
For each episode:
    Initialize state
    While state is not terminal:
        Select action using ε-greedy policy
        Execute action, observe reward and next state
        Store experience in replay buffer
        Sample mini-batch from replay buffer
