Abstract: A method, system, and computer program product for evaluating a geographic atrophy lesion. An image of a geographic atrophy (GA) lesion is received. A first set of values is determined for a set of shape features using the image. A second set of values is determined for a set of textural features using the image. GA progression for the GA lesion is predicted using the first set of values and the second set of values.

Abstract: A data set can be provided that includes an input data element and one or more label data portion definitions that each identify a feature of interest within the input data element. A machine-learning model can generate model-identified portions definitions that identify predicted feature of interests within the input data element. At least one false negative (where a feature of interest is identified without a corresponding predicted feature of interest) and at least one false positive (where a predicted feature of interest is identified without a corresponding feature of interest) can be a identified. A class-disparate loss function can be provided that is configured to penalize false negatives more than at least some false positives. A loss can be calculated using the class-disparate loss function. A set of parameter values of the machine-learning model can be determined based on the loss.
