    Generative AI in Finance

    Why does every naive data scientist who tries to predict stock prices end up depressed? Finance systematically breaks standard AI. You'll discover the four methodological pitfalls: data scarcity (10 years of daily data = only 2,500 observations—laughably insufficient), look-ahead bias (accidentally using future data), the unconditional trap (models validate but can't predict what matters), and heavy tails (the rare crashes that define risk). The analogy that sticks: "It's like having an umbrella that doesn't work when it rains." But there's a solution. Task-driven training matches the P&L of benchmark strategies instead of learning impossible 10,000-dimensional distributions. You'll hear about dynamic portfolios that spontaneously switched hedging instruments during COVID, lasso regression for cost-effective hedging, and the "Persona Ledger" method—LLM-generated synthetic data with accounting rules as constraints. Finance breaks AI, but sophisticated methodologies are fixing it. Topics Covered - The "naive data scientist depression": why finance breaks standard AI - Four methodological pitfalls: data scarcity, look-ahead bias, unconditional trap, heavy tails - Task-driven training: matching strategy P&L instead of price prediction - Dynamic vs. static portfolios (encoding timing and regime changes) - Lasso regression for sparse hedging (minimizing transaction costs) - Agentic pipelines: GPU-accelerated end-to-end workflows - LLM challenges: time travel problem, implicit investment biases, stubbornness - Persona Ledger: LLM-generated synthetic data with stateful verification

  2. Foundation Models' Brain Body

    Foundation Models' Brain Body

    Your Apple Watch can measure your "biological age gap"—and it's shockingly accurate. Smokers appear 4-6 years older. Pregnancy temporarily ages you 3.5 years. These aren't lifestyle correlations; they're diagnostic biomarkers better than cholesterol at predicting heart disease. You'll discover how self-supervised learning unlocks this power from noisy brain and body signals without requiring expensive manual labels. An elegantly simple trick—teaching models which EEG windows are close or far apart in time—achieves massive data efficiency. But the real breakthrough? Brain-computer interfaces that read your subconscious "oops" signal. When you intend to click but your brain detects an error, the system suppresses it—boosting accuracy from 90% to 99%. The scaling is imminent: from dozens of hours of brain data to millions. Topics Covered - Self-supervised learning (SSL): learning data structure without labels - The relative positioning task for EEG: elegantly simple, incredibly powerful - Scaling laws: more hours per subject > more subjects (depth > breadth) - Dual-branch cognitive decoding: brain activity → semantic meaning - Image reconstruction from brain signals (proving semantic decoding works) - PPG age gap biomarker: 2x heart disease rate in young adults, better than cholesterol - BrainJapa and BrainHarmony for MCI prediction - Synchron's Stentrode: minimally invasive BCI via jugular vein - Error detection primitive: subconscious "oops" signal for 90% → 99% accuracy
