Many quant models fail because overlapping event samples are treated as equally important. This article explains Uniqueness, sample weights, and why this is a data structure issue — not a modeling trick. Read more: https://t.co/Uu3LO1uioS #QuantTrading #SampleWeights #Uniqueness

Most quant models fail not because of weak algorithms, but because event-based data is treated as i.i.d. This article explains sample overlap and why it’s a data structure issue — not tuning. Read more: https://t.co/NI9RybLs3U #QuantTrading #FinML #SampleOverlap
