Month 1: Introduction to AI & Basic Concepts
Module 1: Introduction to Artificial Intelligence
What is AI?
Definition: AI refers to creating machines or software that can perform tasks that typically require human intelligence (e.g., visual perception, speech recognition, decision-making).
Types of AI:
Weak AI (Narrow AI): Designed to perform a specific task (e.g., voice assistants, image recognition).
Strong AI (General AI): Has the potential to perform any intellectual task that a human can do (still theoretical).
Example: Siri or Google Assistant is an example of Weak AI.
Module 2: Python for AI
Installing Python and Libraries:
Install Python and set up essential libraries: NumPy, Pandas, Matplotlib, Scikit-learn, TensorFlow, Keras.
Example:
bash
CopyEdit
pip install numpy pandas matplotlib scikit-learn tensorflow keras
Data Structures in Python:
Lists, tuples, dictionaries, sets for data storage and manipulation.
Example:
python
CopyEdit
my_list = [1, 2, 3, 4]
my_dict = {"name": "Alice", "age": 25}
Basic Algorithms: Introduction to basic algorithms and how they work with Python.
Example:
python
CopyEdit
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)
print(factorial(5)) # Output: 120
Month 2: Core AI Techniques
Module 3: Machine Learning Basics
Introduction to Machine Learning:
Definition: Machine Learning (ML) is a subset of AI that focuses on building algorithms that learn from data and make predictions.
Types of ML:
Supervised Learning: Model is trained with labeled data (e.g., regression, classification).
Unsupervised Learning: Model is trained with unlabeled data (e.g., clustering).
Reinforcement Learning: Learning through trial and error (e.g., self-driving cars).
Example: Predicting house prices using supervised learning.
Supervised Learning:
Regression: Predicting continuous values.
Classification: Categorizing data into predefined classes.
Example (Linear Regression):
python
CopyEdit
from sklearn.linear_model import LinearRegression
import numpy as np
# Sample Data: House size vs Price
X = np.array([[1000], [1500], [2000], [2500], [3000]]) # Square footage
y = np.array([200000, 250000, 300000, 350000, 400000]) # Price in dollars
model = LinearRegression()
model.fit(X, y)
predicted_price = model.predict([[1200]]) # Predict price for 1200 sqft
print(predicted_price) # Output: 220000
Module 4: Data Preprocessing and Feature Engineering
Data Preprocessing:
Cleaning data (handling missing values, outliers).
Normalizing data (scaling values between 0 and 1).
Example:
python
CopyEdit
from sklearn.preprocessing import StandardScaler
scaler = StandardScaler()
scaled_data = scaler.fit_transform(data) # Scaling the data
Feature Engineering:
Feature Selection: Choosing relevant features for the model.
Feature Extraction: Transforming raw data into usable features.
Module 5: Supervised Learning Algorithms
Linear Regression:
Predicts continuous values based on input features.
Example:
python
CopyEdit
from sklearn.linear_model import LinearRegression
model = LinearRegression()
model.fit(X_train, y_train) # Train the model
predictions = model.predict(X_test) # Make predictions
Logistic Regression:
Used for binary classification problems (e.g., predicting whether an email is spam or not).
Example:
python
CopyEdit
from sklearn.linear_model import LogisticRegression
model = LogisticRegression()
model.fit(X_train, y_train)
predictions = model.predict(X_test)
Decision Trees: Classifies data based on feature values by constructing a tree-like model.
Example:
python
CopyEdit
from sklearn.tree import DecisionTreeClassifier
model = DecisionTreeClassifier()
model.fit(X_train, y_train)
Month 3: Advanced AI Techniques & Projects
Module 6: Unsupervised Learning and Clustering
K-Means Clustering:
A method for partitioning data into clusters based on similarity.
Example:
python
CopyEdit
from sklearn.cluster import KMeans
# Data points for clustering
data = [[1, 2], [1, 4], [1, 0], [4, 2], [4, 4], [4, 0]]
model = KMeans(n_clusters=2)
model.fit(data)
clusters = model.predict([[0, 0], [4, 4]])
print(clusters) # Output: [1, 0] (cluster assignments)
Module 7: Deep Learning Fundamentals
What is Deep Learning?:
A subset of machine learning using neural networks with multiple layers (also called deep neural networks).
Introduction to Neural Networks:
Perceptrons: A basic neural network model for binary classification.
Example: Simple neural network using Keras.
python
CopyEdit
from keras.models import Sequential
from keras.layers import Dense
model = Sequential()
model.add(Dense(units=10, activation='relu', input_dim=5)) # Hidden Layer
model.add(Dense(units=1, activation='sigmoid')) # Output Layer
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
model.fit(X_train, y_train, epochs=10, batch_size=32)
Module 8: Natural Language Processing (NLP)
Introduction to NLP:
Text Processing: Tokenization, stemming, lemmatization, and stopword removal.
Example (Tokenization):
python
CopyEdit
from nltk.tokenize import word_tokenize
text = "AI is transforming the world!"
tokens = word_tokenize(text)
print(tokens) # Output: ['AI', 'is', 'transforming', 'the', 'world', '!']
Text Classification: Use machine learning to classify text into categories.
Example (Sentiment Analysis):
python
CopyEdit
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.naive_bayes import MultinomialNB
# Sample data
X = ["I love programming", "I hate bugs", "Python is great", "I dislike errors"]
y = [1, 0, 1, 0] # 1 = positive, 0 = negative
vectorizer = CountVectorizer()
X_transformed = vectorizer.fit_transform(X)
model = MultinomialNB()
model.fit(X_transformed, y)
sentiment = model.predict(vectorizer.transform(["I love coding"]))
print(sentiment) # Output: [1] (positive sentiment)
