AI and Machine Learning - Roadmap

Step 1: Fundamentals of AI and ML

1. Mathematics (Basics First)

• Linear Algebra (vectors, matrices, operations)
• Probability and Statistics (distributions, Bayes' theorem)
• Calculus (derivatives, integrals, optimization)
• Recommended Resources:
• Khan Academy Math Courses
• “The Elements of Statistical Learning” (Book)
• Programming SkillsLearn Python for ML: Focus on libraries like NumPy, Pandas, and Matplotlib.
• Practice with beginner projects.
• Resources:
• "Automate the Boring Stuff with Python" (Book)
• freeCodeCamp Python Tutorials

Step 2: Core ML Concepts

Data Preprocessing

• Cleaning and transforming datasets.
• Working with structured (CSV, databases) and unstructured (text, images) data.
• Tools: Pandas, NumPy, Scikit-learn.

Supervised Learning

• Algorithms: Linear Regression, Logistic Regression, Decision Trees, Random Forests.
• Concept of training, testing, and validating models.

Unsupervised Learning

• Algorithms: K-Means, Hierarchical Clustering, Principal Component Analysis (PCA).

Reinforcement Learning (Optional for Beginners)

• Learn the basics of agents and reward systems.

1. Resources:

• Courses: Andrew Ng’s ML Course
• Books: “Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow” by Aurélien Géron.

Step 3: Deep Learning

Neural Networks

• Basics of perceptrons, activation functions, backpropagation.
• Learn frameworks like TensorFlow and PyTorch.

Specialized Architectures

• Convolutional Neural Networks (CNNs): For image data.
• Recurrent Neural Networks (RNNs): For sequential data (e.g., text, time series).

Pre-Trained Models

• Use transfer learning with pre-trained models (e.g., ResNet, BERT).

Resources:

• Deep Learning Specialization by Andrew Ng (Coursera).
• "Deep Learning for Beginners" by François Chollet.

Step 4: Real-World Applications

Natural Language Processing (NLP)

• Basics of text analysis, sentiment detection.
• Tools: Hugging Face, NLTK, SpaCy.

Computer Vision

• Image classification, object detection (YOLO, OpenCV).

Recommendation Systems

• Collaborative filtering, content-based methods.

AI for Projects

• Build small projects like chatbots, image classifiers, or recommendation engines.

Step 5: Advanced Topics

Optimization Techniques

• Hyperparameter tuning (Grid Search, Random Search).
• Regularization techniques (L1, L2).

Productionizing ML Models

• Learn to deploy models with tools like Flask, FastAPI, or AWS SageMaker.
• Focus on MLOps concepts: CI/CD for ML, model monitoring.

Ethics in AI

• Bias in algorithms.
• Responsible AI practices.

Step 6: Building Your Portfolio

Create a GitHub repository with your projects.

• Example Projects:
• Predict house prices using regression.
• Classify images using CNNs.
• Build a sentiment analysis model.

Participate in competitions on platforms like Kaggle.
