Quantifying User Behavior Patterns to Build Better Predictive Features
Simply knowing a user’s clicks—like a 35-year-old male in Seattle clicking 12 times last month—reveals little about their intent. Quantifying user behavior patterns, however, unlocks powerful predictive capabilities. We move beyond superficial metrics to analyze sequences, durations, and interactions, building features that genuinely anticipate user needs. This approach transforms raw data into actionable insights, driving more effective product development and personalized experiences.

MS in Operations Research vs Data Science
Choosing between an MS in Operations Research (OR) and Data Science after a Data Science undergraduate degree presents a strategic career decision. While specialization in Data Science offers continued focus, an OR degree can broaden your problem-solving toolkit and potentially unlock unique opportunities, especially given your current Operations Research Analyst role. OR is demonstrably math-intensive; beyond your existing calculus, linear algebra, and statistics foundation, expect to delve into optimization, stochastic modeling, and simulation.
Why Your Best Predictive Model Gives the Wrong Treatment Effect
Even the most accurate predictive models can mislead when estimating treatment effects. Relying solely on prediction-driven variable selection often overlooks crucial confounders, leading to inaccurate conclusions about cause and effect. This stems from prediction models optimizing for accuracy, not causal inference. Bayesian Adjustment for Confounding offers a promising approach to mitigate this, systematically accounting for potential confounders.
