🧠 5. Advanced Machine Learning and AI
As you move beyond basic models like decision trees and linear regression, advanced machine learning and AI introduce more powerful, scalable, and intelligent systems for solving complex real-world problems.
🔍 What is Advanced Machine Learning?
Advanced ML includes algorithms and techniques that go beyond traditional models. It focuses on:
Improving prediction accuracy
Handling unstructured data (images, text, audio)
Making models more autonomous and adaptive
⚙️ Key Topics in Advanced Machine Learning and AI
1. Deep Learning
A subset of ML that uses neural networks with many layers (deep architectures).
Applications:
Image recognition (CNNs)
Natural language processing (RNNs, Transformers)
Speech recognition
Autonomous driving
Key Technologies:
TensorFlow, PyTorch
CNNs (Convolutional Neural Networks)
RNNs, LSTMs (Recurrent Neural Networks)
Transformers (used in models like BERT, GPT)
2. Ensemble Learning
Combines predictions from multiple models to boost accuracy.
Types:
Bagging (e.g., Random Forest)
Boosting (e.g., XGBoost, LightGBM, CatBoost)
Stacking (combining multiple models with a meta-model)
3. Unsupervised Learning
Used to find patterns in data without labeled outcomes.
Algorithms:
Clustering: K-Means, DBSCAN
Dimensionality Reduction: PCA, t-SNE, UMAP
Anomaly Detection
4. Reinforcement Learning (RL)
An agent learns to make decisions by interacting with an environment and receiving rewards or penalties.
Examples:
Game playing (e.g., AlphaGo)
Robotics
Trading algorithms
Key Concepts:
States, Actions, Rewards
Q-Learning, Policy Gradient, Deep Q-Networks (DQN)
5. Natural Language Processing (NLP)
