Assignment 1 [5 Marks]
Identify and describe 5 applications of machine learning in the education sector. For each application, provide a detailed explanation and include examples of how it benefits students, teachers, or educational institutions. Include relevant references.
Assignment 2 [25 Marks]
Your task is to select a dataset from HND assignment help that involves a multi-class classification problem. You will apply three different supervised learning algorithms to solve the problem. You are required to document and explain every step of the machine learning process, from data preprocessing to model evaluation. This assignment aims to assess your understanding of the machine learning workflow and your ability to implement and optimize machine learning models for multi-class classification.
1. Dataset Selection:
- Choose a multi-class classification dataset from Kaggle. Ensure the dataset has more than two classes in the target variable.
Provide a brief description of the dataset, including its features, target variable, and any relevant context.

- Handling Missing Values: Describe how you handled any missing data in the dataset and justify your approach.
- Normalization: Explain how you normalized the data, and why it was necessary for your selected algorithms.
- Feature Selection: Identify and select the most relevant features for your models. Explain the technique you used for feature selection.
Handling Imbalanced Classes: If your dataset has imbalanced classes, explain the technique you used to address this issue.
- Apply three different supervised learning algorithms suitable for multi-class classification.
- Split the data into training and testing sets. Justify your choice of split ratio.
Train each model on the training data and test it on the testing data.
- Discuss the hyperparameter tuning process for each model and the methods you used.
Compare the performance of the models before and after optimization, focusing on how well they handle the multi-class problem.
- Explain the evaluation metrics used for multi-class classification (e.g., Accuracy, Precision, Recall, F1-Score and Confusion Matrix).
Provide a comparative analysis of the models based on these metrics, discussing which model performed best and why.
