QuantSynth scores forecasts on decisions, not RMSE

QuantSynth is a forecast evaluation tool that replaces traditional metrics like RMSE with decision-aligned scores (FIS and CER) that measure whether a prediction would have led to a correct real-world action. Built by an MLE in finance who found that low-error models kept losing money in production, it also runs a pre-modeling dataset diagnostic to catch leakage, wrong splits, and target column errors before training begins.

// ANALYSIS

The insight is real and widely felt — directional accuracy often matters more than numerical closeness in applied ML — but QuantSynth is essentially proposing proprietary metrics with no peer-reviewed backing yet.

–FIS (Forecast Investment Score) and CER (Confidence Efficiency Ratio) are QuantSynth-coined terms; the underlying ideas (IC, economic loss functions) predate this, so adoption depends on whether practitioners trust the framing
–The dataset diagnostic layer is the more immediately practical pitch — catching leakage, temporal split errors, and wrong target columns before training is a real pain point most MLEs recognize
–The tool is upload-only (max 6 columns, in-memory, no storage), which limits its use to evaluation and EDA; it's not a full ML pipeline
–Very early stage: near-zero Reddit traction (score 0, 10 comments), no Product Hunt listing, no external press
–Roadmap includes AutoML on top of the dataset intelligence layer, which would be a much bigger product if executed
