Personalizing blood sugar prediction with a custom AI trained on 115 days of data
115 days of personal CGM data, plus a synthetic training set representing 19,200 years of simulated diabetes, and the result is a 31,253-parameter transformer that predicts blood sugar two hours ahead. What stands out is the model's ability to infer time of day from glucose patterns alone, a capability that emerges only with longer context windows. It is still less reliable than the user for near-term hypoglycemia, which is an honest and human-centered admission.
Scaling demand forecasting across 40 locations starts with one smart model choice
Scaling demand forecasting across 40 locations starts with one smart model choice. A single global model with strong location features can learn regional patterns without averaging them out, especially if you include location embeddings and demographic indicators. Grouping similar locations as a hybrid approach is worth exploring too. On synthetic data, hold out entire locations during validation to test real generalization. Time-series cross-validation with temporal splits prevents leakage. Consider gradient-boosted trees or a Transformer-based architecture for capturing both local trends and cross-location patterns.
When AI Sounds Confident, Verify It Knows the Answer
Arun Mishra's eval harness exposed a flaw that should worry any team shipping LLM-assisted tools: the model was most confident precisely when it was most wrong. Qualitative review caught nothing because the explanations sounded authoritative. That is the trap. We test for fluency when correctness is what matters. Mishra's approach, measuring accuracy against synthetic ground truth, reveals the gap between plausible and correct. It is tedious work, but skipping it means deploying tools that fail quietly.
