Abstract: Implementations are described herein for improving compliance with length constraints imposed on generative model output. In various implementations, a candidate generative model training example may be retrieved and include an input prompt and a generative model response that was generated by processing the input prompt using one or more generative models. The input prompt may be analyzed to identify length constraint(s) intended to be imposed on the generative model response. The generative model response may be evaluated for compliance with the length constraint(s). Based on a determination that the generative model response fails to comply with one or more of the length constraints, the candidate generative model training example may be modified to generate a synthetic generative model training example for which one or more length constraints are satisfied. The generative model(s) may be trained using the synthetic generative model training example.

Abstract: A system associated with quantifying a density level of tumor-infiltrating lymphocytes, based on prediction of reconstructed TIL information associated with tumoral tissue image data during pathology analysis of the tissue image data is disclosed. The system receives digitized diagnostic and stained whole-slide image data related to tissue of a particular type of tumoral data. Defined are regions of interest that represents a portion of, or a full image of the whole-slide image data. The image data is encoded into segmented data portions based on convolutional autoencoding of objects associated with the collection of image data. The density of tumor-infiltrating lymphocytes is determined of bounded segmented data portions for respective classification of the regions of interest. A classification label is assigned to the regions of interest. It is determined whether an assigned classification label is above a pre-determined threshold probability value of lymphocyte infiltrated.
