What You Will Learn

Simple Linear Regression in Python

Experience hands-on training by using Python to implement a simple linear regression model. Explore a real dataset to predict sales based on TV ad spend using libraries like Pandas and sklearn.

Topics Covered:

  • Reading & Understanding the Data
    Data preparation is crucial in regression modeling. In this topic, we’ll use Python's Pandas library to read and explore the dataset, examining the relationship between advertising spend and sales. Learn techniques like data cleaning, handling missing values, and basic data visualization to understand the dataset’s structure.

  • Hypothesis Testing
    Hypothesis testing helps validate the assumptions of regression models. You’ll learn how to test the statistical significance of your predictor variable (e.g., TV advertising budget) using t-tests and p-values. This will allow you to determine if the predictor variable has a meaningful relationship with the dependent variable (sales).

  • Building a Linear Model
    We’ll guide you through the process of building a simple linear regression model using the statsmodels and scikit-learn libraries. Learn to interpret model outputs like coefficients, intercepts, and p-values, and understand how these components contribute to the prediction process.

  • Linear Regression using SKLearn
    Using scikit-learn, a popular Python library for machine learning, we’ll walk you through training a linear regression model, making predictions, and evaluating model performance using metrics like Mean Absolute Error (MAE) and R-squared. Learn how to split the dataset into training and testing sets for better validation.

Multiple Linear Regression

Learn how to build more complex models using multiple variables, such as TV, radio, and newspaper marketing budgets. Master the challenges and techniques for selecting optimal features.

Topics Covered:

  • Multicollinearity
    Multicollinearity occurs when independent variables are highly correlated with each other, causing instability in regression models. We’ll cover how to detect multicollinearity using metrics like the Variance Inflation Factor (VIF), and strategies to address it, such as removing redundant variables or applying principal component analysis.

  • Dealing with Categorical Variables
    Many datasets include categorical data (e.g., gender, region, product type) that cannot be used directly in regression models. Learn techniques like one-hot encoding, label encoding, and ordinal encoding to convert categorical variables into numerical representations, making them usable in regression analysis.

  • Model Assessment
    Learn how to assess the performance of your multiple regression model. We'll cover important evaluation metrics such as Adjusted R², F-statistics, and the Root Mean Squared Error (RMSE), which give deeper insights into how well your model generalizes to unseen data and whether any adjustments are needed.

  • Feature Selection
    In multiple regression models, having too many variables can lead to overfitting, where the model is too complex and fits the noise in the data. Learn methods like stepwise regression, backward elimination, and forward selection to identify the most important predictors, ensuring a simpler and more efficient model.

Multiple Linear Regression in Python

Learn to implement a multiple linear regression model using a real dataset. Use Python’s data analysis tools to prepare data, build models, and assess performance.

Topics Covered:

  • Data Preparation
    In this section, we’ll focus on preparing a real-world dataset, such as housing prices, for analysis. Learn how to clean the data, deal with missing values, and scale features before fitting a regression model. We’ll also cover feature engineering techniques like creating new variables that improve model performance.

  • Building the Model
    Once the data is prepared, we’ll guide you through the process of building a multiple linear regression model using Python’s scikit-learn. You’ll learn to fit the model on training data and use it to make predictions. We’ll also discuss how to interpret model coefficients and assess the goodness-of-fit.

  • Residual Analysis & Predictions
    After building the model, it’s crucial to perform residual analysis to check for patterns that indicate model weaknesses, such as heteroscedasticity or non-linearity. Learn how to visualize residuals and refine the model for better predictive power, ensuring that the predictions are accurate and reliable.

  • Variable Selection using RFE
    Recursive Feature Elimination (RFE) is a method for improving model accuracy by selecting only the most important features. We’ll show you how to use RFE to iteratively remove features and select the best subset of variables for your model, improving performance while reducing overfitting.

Industry Relevance of Linear Regression

Understand how linear regression models are applied across various industries. Explore case studies and learn to use regression for decision-making in business scenarios.

Topics Covered:

7What do you mean by linear regression?

Linear regression is a statistical technique that models the relationship between a dependent variable and one or more independent variables. It assumes that there is a linear relationship between the inputs and the output, and it tries to fit the best line (called the regression line) to predict the output based on the inputs. It’s one of the simplest forms of predictive modeling.

8What is the application of linear regression?

Linear regression is widely used in prediction and forecasting. For instance, it can predict house prices based on various factors (square footage, location, etc.), forecast sales based on advertising spend, or predict stock market prices. Essentially, any problem that involves predicting a continuous outcome based on input variables can benefit from linear regression.

9What is linear regression in machine learning?

In machine learning, linear regression is a supervised learning technique used to model the relationship between a dependent variable and one or more independent variables. The goal is to train the model on historical data and then use it to predict the dependent variable for new data. It’s often one of the first models used in machine learning because of its simplicity and effectiveness.

10What are the types of regression?

There are several types of regression, each suited to different data structures:

  1. Simple Linear Regression: Models the relationship between two variables (one independent and one dependent).

  2. Multiple Linear Regression: Extends simple linear regression to predict outcomes based on multiple independent variables.

  3. Logistic Regression: Used for binary classification problems (e.g., yes/no outcomes).

  4. Polynomial Regression: Models non-linear relationships by introducing polynomial terms in the regression equation. Each type has specific use cases, depending on the nature of the data and the problem.

11What is the p-value in regression?

The p-value in regression tests the null hypothesis that the predictor variable has no effect on the dependent variable. A small p-value (typically less than 0.05) suggests that the predictor is statistically significant and is likely to contribute meaningfully to the model. In contrast, a large p-value indicates that the predictor may not be useful, and further analysis might be required.


12What tools and frameworks will I learn to build Generative AI models?

The course introduces industry-standard frameworks like TensorFlow, PyTorch, and Hugging Face Transformers for building and fine-tuning generative models. You'll also gain hands-on experience with tools such as Google Colab, OpenAI APIs, and Diffusers for developing applications across text, image, and audio generation.

13How can I fine-tune a pre-trained Generative AI model for my specific use case?

You’ll learn how to fine-tune pre-trained models (like GPT, BERT, and Stable Diffusion) using your own dataset. The course covers essential techniques including transfer learning, parameter-efficient fine-tuning (PEFT), prompt engineering, and data augmentation, allowing you to adapt foundational models for custom content generation tasks like chatbots, product descriptions, and visual design.

14Can I deploy my Generative AI models into production using this course?

Yes. The course guides you through deploying generative models using Docker, Streamlit, and Flask APIs, along with integration into cloud platforms such as AWS, Google Cloud, and Hugging Face Spaces. You’ll learn to package your models, monitor performance, and implement safeguards like rate-limiting and content moderation filters to ensure safe, scalable deployment.
