Columbia-Capstone

Final Capstone Project for Columbia University

Problem Statement

30% of users falsely fill out psychometric surveys

How can we validate these user survey responses?

Research Questions

1. Mouse Activity: How do we use user mouse activity to validate survey answers to psychometric questions?
2. Response Time: Does the variability in survey response time indicate suspicious behavior?
3. Survey Question: Does the level of suspicious behavior vary across different types of survey questions?

Approach

Apply unsupervised & supervised learning techniques to identify users who exhibit suspicious behavior in survey completion

Expected Results

• Create a model that outperforms current validation methods
• Indentify rates of Fraudulent Response
• Reduce survey cost by at least 30%
