EventHorizon
An AI forecasting platform built by an independent developer. It covers demand forecasting for small businesses, cryptocurrency price direction prediction, and a model validation toolkit, with emphasis on model evaluation and real-world validation.
Timeline (last 90 days)
A 14-year-old independent developer spent 276 days building an AI forecasting platform called EventHorizon, covering demand forecasting, cryptocurrency direction prediction, and model validation tools.
On the M5 Walmart dataset, the EventHorizon demand forecasting model achieved a WAPE of 31.03%, while the baseline model's WAPE was 44.4%, achieving roughly a 30% error reduction relative to the baseline.
The EventHorizon model's improvements remained consistent across evaluations at all seven stores.
The developer points out that strong performance on benchmarks does not equal successful deployment in real business environments, and the M5 dataset cannot prove that the same performance can transfer to a specific bakery, flower shop, or other small business.
The short-term BTC/USDT price direction prediction system built by the developer uses a Transformer architecture combined with BiLSTM and cross-attention mechanisms, with about 1.5 million training samples, and the model's direction accuracy is about 60%, a clear improvement over the roughly 52% baseline.
After factoring in trading fees and execution-related costs, the BTC/USDT prediction system's roughly 60% direction accuracy is not economically viable.
The developer built a validation toolkit that includes forward rolling validation splits, block bootstrap and interval bootstrap procedures, permutation tests, and the WAPE and MASE evaluation metrics.
The developer proactively contacted small businesses (including bakeries and flower shops) to understand their needs, inventory, and daily production decisions, but the outreach has so far produced no paying customers or real pilots.
The principles the developer summarized include: define a baseline first, design validation around the data, distinguish technical progress from product progress, honestly document limitations, and talk to potential users earlier.
The core insight of the EventHorizon project is: building a model is an engineering task, while judging whether a model is trustworthy and whether it solves a real problem is a bigger challenge.
