A technical analysis explored the efficacy of Jevíčko, a judgment API from TypeSafe AI's System One, comparing two methods for classification tasks. The first method, direct judgment, uses a single question per data point, while the second, feature extraction, employs 12-14 narrow questions per request and fits local regression models. Experiments revealed that for tasks with clear answers, direct judgment performed comparably or better than feature extraction. However, for more complex tasks relying on subtle stylistic cues, the feature extraction method, when combined with locally fitted weights, significantly outperformed direct judgment and a baseline naive Bayes model, though its confidence scores did not always align with correctness.
