Abstract: Systems and methods for gradient-to-parameter ratio guided feature alignment for model adaptation. To adapt an artificial intelligence (AI) model to different domains, activation statistics for the AI model can be computed from collected domain data. Weights of the AI model can be adjusted based on the activation statistics of the training gradients. The AI model can be fine-tuned by focusing adaptation intensity to layers with attention mechanism by using a ratio of gradient norm over parameter norm to obtain a fine-tuned AI model. The fine-tuned AI model can be employed to perform downstream tasks such as cell segmentation from medical images.
