Abstract: A method for predicting a microsatellite instability (MSI) from a whole slide image based on a self-attention mechanism, in which an image of a tissue region obtained through cellular staining on a tissue sample of a patient serves as a target whole slide image to be predicted. The tissue region is segmented into tissue patches, and stain normalization is performed with staintools. N tumor patches are screened out from the tissue patches, and the N tumor patches are inputted to a preset feature extraction model. Each of the tumor patches are encoded as an M-dimensional feature vector, thereby obtaining a N×M feature matrix; and the N×M feature matrix is inputted to a pre-trained prediction model, such that the prediction model outputs an MSI score of the target whole slide image. The present disclosure predicts the MSI based on deep learning and the cellular staining.

Abstract: Provided are techniques for building and using a sparse Time Series Database (TSDB). Time series records are received from a native TSDB, where each of the time series records includes a timestamp and one or more tags. Timeslots are determined for shards for the sparse TSDB based on the timestamp included in each of the time series records. The sparse TSDB is built by creating the shards for the determined timeslots and storing the time series records in the shards, while filling in empty ranges in the shards. A query that specifies at least one of the one or more tags is received. It is determined whether to execute the query against the sparse TSDB, and, in response to a determination to execute the query against the sparse TSDB, the query is executed against the sparse TSDB to generate results that are returned.
