The slide motivates the project by noting the global water crisis, where 2 billion people lack safe water per WHO, and the need for rapid, accurate potability tests. It proposes using ML to predict potability from chemical/physical parameters, improving health and cutting manual testing costs.

Project Motivation

• Global water crisis: 2B lack safe water (WHO)
• Need rapid, accurate potability tests
• ML predicts from chemical/physical parameters
• Improves health, cuts manual testing costs

The slide defines the problem as binary classification of water potability (1 for potable, 0 for non-potable). It notes challenges like imbalanced data and multicollinearity, targets >95% prediction accuracy, and emphasizes a deployable field-testing solution.

Problem Definition

• Binary classification: Potable (1) vs. Non-potable (0)
• Challenges: Imbalanced data, multicollinearity in features
• Goal: Predict potability with >95% accuracy
• Impact: Deployable solution for field testing

The slide details a dataset of 3276 water source samples with potability as the binary target, where missing values were handled in preprocessing. Key features include ph, Hardness, Solids, Chloramines, Sulfate, Conductivity, OrganicCarbon, Trihalomethanes, and Turbidity.

The slide presents a machine learning methodology workflow with five phases: Data Collection & EDA (dataset acquisition and exploratory analysis), Feature Engineering (scaling and feature selection), Model Training (cross-validation), Hyperparameter Tuning (GridSearchCV), and Evaluation & Selection (performance metrics and model selection). It uses a table format to pair each phase with its key techniques for clarity.
