12+ min ago   (448+ words) The One-Line Summary: A model is "good enough" when it beats a reasonable baseline, meets business requirements, performs consistently across segments, fails gracefully, and the cost of its errors is acceptable. High accuracy alone means nothing without this context. Chef…...

32+ min ago   (853+ words) The tech leads behind IBM's new software library, Mellea, explain how it works and why giving language models explicit requirements can improve performance and lower costs. Large language models still dominate AI leaderboards, but a new class of lighter weight…...

56+ min ago   (799+ words) The One-Line Summary: AUC-ROC measures how well your model can distinguish between classes ACROSS ALL possible thresholds. An AUC of 1.0 means perfect separation. An AUC of 0.5 means your model is no better than random coin flips. It's the ONE number…...

1+ hour, 3+ min ago   (839+ words) The One-Line Summary: Accuracy measures how often you're right overall, but when 96% of your data is one class, a model that predicts that class every time gets 96% accuracy while being completely useless. Accuracy rewards laziness when classes are imbalanced. Maria…...

1+ hour, 6+ min ago   (591+ words) The One-Line Summary: Accuracy asks "how often are you right overall?" Precision asks "when you say wolf, are you sure?" Recall asks "did you catch all the wolves?" F1 asks "can you balance confidence with coverage?" Different questions, different answers, different…...
