Breakthrough Performance with Context Constrained Radiation Measurements

Noah Mcferran | 23-ERD-041

Executive Summary

We will develop new radiation detector algorithms and system designs that leverage a machine learning approach where training data can be limited in real time based on contextual information collected by non-radiation sensors or user observations. The real-time tuning of our machine learning analyses can dramatically improve performance of current and future radiation detector systems, and the machine learning developments will provide benchmarks to compare with other training data removal machine learning methods.
