Regression and Classification Metrics Dashboard for Model Evaluation

Added Jun 2025 3 design docs

Model evaluation is where data science becomes accountable: a single accuracy number hides more than it reveals, and practitioners need fluency across regression and classification metrics to judge a model honestly. This project builds the tool that makes those metrics concrete and comparable. The intern creates a Streamlit dashboard where users upload model predictions alongside true values and instantly receive the appropriate evaluation suite. For regression tasks the app computes MAE, MSE, and R-squared with pandas and scikit-learn, pairing the numbers with plots that show how errors are distributed; for classification it renders an annotated confusion matrix and derived metrics so users can see exactly where a model confuses one class for another. The dashboard validates uploads gracefully before computing anything, handling mismatched lengths and malformed files the way a real tool must. The project drills the vocabulary every data scientist is tested on — what each metric measures, when it misleads, and how to read a confusion matrix at a glance — while giving the intern experience building a small, genuinely reusable analytics utility they can point at the outputs of any future model.

Beginner-Friendly Voting and Stacking Classifier Builder

Ensemble learning is usually taught as a formula, but the underlying idea is simple: several weak opinions, combined well, beat one confident guess. This project turns that idea into an application a beginner can experiment with directly, making one of machine learning's most powerful techniques concrete. The intern builds a Streamlit application where users train several simple scikit-learn classifiers on a chosen dataset and combine their predictions using hard and soft voting, stacking, and blending strategies. The interface shows each base model's individual accuracy next to the combined result, so the effect of ensembling is visible immediately rather than taken on faith. Users can swap base models in and out and watch how diversity among the learners changes the ensemble's performance, with Python handling training and evaluation behind a clean interactive front end. The project cements the intern's understanding of why and when ensembles work, gives them working knowledge of scikit-learn's ensemble APIs, and provides practice in building approachable educational tooling — demonstrating they can both apply a core machine learning technique and explain it to someone newer than themselves.

Class Imbalance Correction Demo Using SMOTE Oversampling

Fraud detection, medical screening, and defect prediction all share an inconvenient property: the events worth catching are rare, so naive models score high accuracy by ignoring them entirely. Handling class imbalance is one of the first hard lessons in applied machine learning, and this project teaches it by demonstration rather than by warning. The intern builds a Streamlit application that trains a scikit-learn classifier on an imbalanced dataset twice — once on the raw data and once after applying SMOTE to synthesize minority-class examples — and presents the two results side by side. The app visualizes the class distribution before and after oversampling and reports precision, recall, and F1 for both runs, making it obvious how a model that looked accurate was actually blind to the minority class, and exactly what resampling recovers. Users can adjust the imbalance ratio and resampling settings to explore edge cases interactively. The intern finishes understanding evaluation beyond accuracy, the mechanics and pitfalls of synthetic oversampling, and how to design a demonstration that makes a subtle statistical issue unmistakable to a general audience — a valuable communication skill in any data role.

SHAP Value Explorer for Understanding Model Predictions

A model that predicts well but cannot say why quickly runs into trouble — users distrust it, stakeholders question it, and debugging it becomes guesswork. SHAP values have become the standard first answer to that problem, and this project gives an intern direct working experience with them on data they choose themselves. The intern builds a Streamlit application where users upload a tabular dataset, train a simple scikit-learn model, and immediately explore SHAP explanation plots: summary plots ranking which features matter most overall, and per-prediction views showing how each feature pushed an individual output higher or lower. The app guides users through reading these plots correctly, turning SHAP from an intimidating acronym into a practical everyday tool, with Python handling the modeling pipeline end to end behind the interactive interface. The project builds fluency in model interpretability — a topic employers increasingly treat as core data science rather than a specialty — and gives the intern practice at packaging an explanation workflow into an accessible tool, plus a portfolio piece showing they think critically about what models learn instead of just training them.
