Episode notes
Human-Guided AI Wins Over Blind Modeling
- Versor treats AI and alternative data as tools to solve human-defined problems rather than blind pattern hunts.
- Research starts with a hypothesis, then finds features and models to test that causal idea.
Start With A Written Hypothesis
- Begin research with a clear hypothesis and a written research specification before modeling.
- Ask what data generation process could drive returns and design experiments to test it.
Frame The Problem Before Modeling
- Framing the right problem changes what data and models you use and unlocks better signals.
- Example: merger-arb is not binary; modeling three outcomes (success, failure, competing bid) improves edge.
