The Path to Start This Course

1. Building a Strong Foundation

The course begins with Module 1: Introduction to Machine Learning, where you learn the basics of machine learning and how it differs from rule-based systems. This module introduces the CRISP-DM framework, a structured approach to solving machine learning problems, and the model selection process.

Key Concepts

• Supervised vs. Unsupervised Learning.
• The importance of data in ML.
• Setting up your environment (Python, Jupyter Notebooks, etc.).

Mathematical Foundations

• Basic probability and statistics.
• Understanding data distributions and central tendency.

2. Mastering Regression and Classification

In Module 2: Machine Learning for Regression, you dive into your first project: Car Price Prediction. Here, you learn the fundamentals of linear regression, a cornerstone of machine learning.

Mathematical Foundations

• Linear regression equation:
  \(y = \beta_0 + \beta_1 x_1 + \beta_2 x_2 + \dots + \beta_n x_n + \epsilon\)
• Loss function (Mean Squared Error):
  \(MSE = \frac{1}{n} \sum_{i=1}^{n} (y_i - \hat{y}_i)^2\)
• Regularization techniques (Ridge and Lasso) to prevent overfitting.

In Module 3: Machine Learning for Classification, you work on a Churn Prediction Project. You learn about logistic regression, a key algorithm for binary classification.

• Logistic regression equation:
  \(P(y=1) = \frac{1}{1 + e^{-(\beta_0 + \beta_1 x_1 + \dots + \beta_n x_n)}}\)
• Cross-entropy loss function:
  \(L = -\frac{1}{n} \sum_{i=1}^{n} [y_i \log(\hat{y}_i) + (1 - y_i) \log(1 - \hat{y}_i)]\)

3. Evaluating Models

Module 4: Evaluation Metrics teaches you how to assess the performance of your models. You learn about metrics like accuracy, precision, recall, and ROC-AUC.

Mathematical Foundations

• Precision and Recall:
  \(Precision = \frac{TP}{TP + FP}, \quad Recall = \frac{TP}{TP + FN}\)
• ROC Curve and AUC (Area Under the Curve).

---

4. Deploying Machine Learning Models

In Module 5: Deploying ML Models, you learn how to take your models from development to production. This includes saving and loading models, building APIs with Flask, and deploying to the cloud using AWS.

Key Skills

• Containerization with Docker.
• Setting up virtual environments.
• Deploying models on EC2 instances and AWS Lambda.

---

5. Advanced Techniques: Decision Trees and Ensemble Learning

Module 6: Decision Trees & Ensemble Learning introduces you to more advanced algorithms like Random Forests and Gradient Boosting.

Mathematical Foundations

• Entropy and Information Gain for decision trees:
  \(Entropy(S) = -\sum_{i=1}^{c} p_i \log_2(p_i)\)
• Gradient Boosting minimizes the loss function using gradient descent:
  \(F_m(x) = F_{m-1}(x) + \gamma_m h_m(x)\)

---

6. Deep Learning and Neural Networks

In Module 7: Neural Networks & Deep Learning, you explore TensorFlow and Keras to build deep learning models. You learn about Convolutional Neural Networks (CNNs) and Transfer Learning.

Mathematical Foundations

• Forward and backward propagation.
• Activation functions (ReLU, Sigmoid, Softmax).
• Loss functions for neural networks (e.g., categorical cross-entropy).

---

7. Serverless and Scalable ML

Module 8: Serverless Deep Learning introduces you to serverless architectures using AWS Lambda and TensorFlow Lite. You learn how to deploy lightweight models for real-time inference.

---

8. Kubernetes and Model Serving

Finally, in Module 9: Kubernetes & TensorFlow Serving, you learn how to deploy machine learning models at scale using Kubernetes and TensorFlow Serving.

Key Skills

• Basics of Kubernetes (pods, services, deployments).
• Serving models with TensorFlow Serving.
