Project Description

This project aims to predict university admissions based on historical data using several machine learning models. A dataset of over 10,000 student records was utilized, containing information such as GRE score, TOEFL score, CGPA, SOP, LOR, and research experience. Various machine learning algorithms were analyzed, including Decision Tree, Support Vector Machine (SVM), Naive Bayes, and Neural Networks, to determine the best-performing model for predicting admissions.

Models & Algorithms

1. Decision Tree: Built a model using a decision tree classifier to analyze the contribution of different factors. Good for interpreting key predictors but prone to overfitting.
2. Naive Bayes: Implemented Naive Bayes to predict admission probabilities. The model is fast but works better with categorical features.
3. Support Vector Machine (SVM): Used SVM to classify applicants based on their academic profiles. SVM was effective in handling nonlinear relationships in the dataset.
4. Gradient Boosting: Utilized gradient boosting to enhance the accuracy by reducing prediction errors. It outperformed other models in terms of precision.
5. Neural Networks: Employed a neural network to simulate complex patterns between admission features. The network provided the highest accuracy due to its deep learning structure.

Key Features of the Dataset:

• GRE Score: Standardized test score used for graduate admissions.
• TOEFL Score: English proficiency score.
• University Rating: Rating of the applicant's undergraduate institution.
• SOP: Statement of Purpose score.
• LOR: Letter of Recommendation score.
• CGPA: Cumulative Grade Point Average.
• Research Experience: Binary indicator of research experience.
• Chance of Admit: The target variable, indicating the likelihood of admission.

Visualization & Analysis

Visualizations were created to compare the performance of the different models:

• Accuracy: Neural Networks and Gradient Boosting had the highest accuracy.
• Confusion Matrix: Displayed to analyze false positives and false negatives.
• Feature Importance: GRE score, CGPA, and research experience were the top predictors of admission success.

Informal Description

This system predicts the likelihood of a student's acceptance to a university based on their academic performance and other relevant factors. It provides personalized insights for students, helping them understand their chances and allowing institutions to optimize their admissions process.

Formal Description

• Task (T): Predict admission outcomes using academic and extracurricular data.
• Experience (E): Historical admission data from over 10,000 applicants.
• Performance (P): The system's accuracy in predicting admissions, achieved 85% accuracy.

Assumptions

• Applicant Profile Stability: Assumes that students' academic and extracurricular profiles are stable.
• Sufficient Historical Data: Relies on the availability of relevant data for training.
• Incomplete Data: The system can still make accurate predictions even if some data is missing.

Benefits of the System

• For Applicants: Provides personalized insights, helping them improve their profiles for future applications.
• For Institutions: Optimizes the admissions process by providing data-driven decisions, improving transparency, and offering competitive insights into the applicant pool.

Conclusion

This project developed a comprehensive machine learning-based system for predicting university admissions, using a variety of models to ensure high accuracy. The insights gained will improve both student engagement and institutional decision-making.
