Match Your Loss to Your Cost: Asymmetric Losses and Conformal Capacity Bands for Backbone Traffic Forecasting

A network operator pays far more for a capacity shortfall than for spare headroom, so this trains the traffic forecaster on that real cost instead of on RMSE.

Mean overload rate against mean over-provisioning cost on Abilene as the training ratio is swept from 1:1 to 100:1. Overload falls by more than two orders of magnitude as cost rises, and the 1:1 point coincides with the MSE baseline.Mean overload rate against mean over-provisioning cost on Abilene as the training ratio is swept from 1:1 to 100:1.

Sweeping the training ratio on Abilene (DLinear, 20 seeds). The 1:1 point lands on the MSE baseline exactly, since α = β = 1 recovers MSE.

Scheduled Partial-Credit RL for Reliable Code Generation with Small Language Models (WIP)

Handing a small model from binary rewards to partial credit partway through training lifts its syntax-valid output from 18% to 63%.

Fixing Performance Bugs Through LLM Explanations

Training a model on written explanations of Java performance bugs, rather than on labels alone, raises detection accuracy from 67% to 84%.

Exhibit A

An AI code reviewer that may only report a bug when it can hand you a test that fails on the broken code and passes on the fix, and stays silent when it cannot.

Tollgate

An industrial inspection agent that sends a frame to the cloud based on what a mistake would cost, not on how confident the model happens to feel.

Accuracy against cloud spend for three routing modes. Local-only reaches 0.951 accuracy at zero cloud spend, the hybrid router 0.988 at 57% of cloud-only spend, and cloud-only 0.992 at full spend.Accuracy against cloud spend for three routing modes.

Accuracy vs cloud spend on MVTec, six categories. Routing by cost keeps 99.6% of cloud-only accuracy for 57% of the spend.
