US 12,014,814 B2 · Methods and systems for tuning a static model

Abstract

Methods and systems are provided for tuning a static model with multiple operating points to adjust model performance without retraining the model or triggering a new regulatory clearance. In one embodiment, a method comprises, responsive to a request to tune a model, obtaining a tuning dataset including a set of medical images, executing the model using the set of medical images as input to generate model tuning output, and determining, for each operating point of a set of operating points, a set of tuning metric values based on the tuning dataset and the model tuning output relative to each operating point. An operating point from the set of operating points may be selected based on each set of tuning metric values and, upon a request to analyze a subsequent medical image, a representation of a finding output from the static model executed at the selected operating point.

A method, comprising:

responsive to a request to tune a pre-trained static model, obtaining a tuning dataset including a set of medical images;
executing the pre-trained static model using the set of medical images as input to generate model tuning output;
determining, for each operating point of a set of operating points, a set of tuning metric values based on the tuning dataset and the model tuning output relative to each operating point;
selecting a tuning metric;
automatically determining a target model operating point based on the selected tuning metric;
selecting an operating point from the set of operating points based on each set of tuning metric values, the set of operating points including the target model operating point that was automatically determined;
and
upon a request to analyze a subsequent medical image, outputting a representation of a finding output of the pre-trained static model executed at the selected operating point.
