Censored Data as Evidence: Time-to-Event Modeling Across Grid, EdTech, and Healthcare Prediction Problems

Most fault-prediction, churn-prediction, and risk-prediction work defaults to binary classification: will this thing happen in the next N days, yes or no. That framing throws away information. An asset that hasn’t failed yet, a student who hasn’t dropped out yet, a patient who hasn’t had a recurrence yet — none of those are missing data points. They’re censored observations, and each one bounds the outcome even without an event attached to it. I’ve built this reframe myself for one of these problems. It turns out the same shape already exists, as documented published work, in two other domains I care … Continue reading Censored Data as Evidence: Time-to-Event Modeling Across Grid, EdTech, and Healthcare Prediction Problems

Podcast: Machine Learning and the Electric Grid with Aaron Epel from Stem

Aaron Epel, Senior Data Scientist at Stem, discusses the impact of machine learning on fault prediction, asset failure prediction, and preventive maintenance scheduling for energy grid operators. The conversation covers the challenges of data science in handling rare events and imbalanced datasets, as well as the future potential of ML in this field.
