Abstract: The present disclosure describes techniques of performing machine unlearning in a recommendation model. An unlearning process of the recommendation model may be initiated in response to receiving a request for deleting a fraction of user data from any particular user. The recommendation model may be pre-trained to recommend content to users based at least in part on user data. Values of entries in a matrix corresponding to the fraction of user data may be configured as zero. The matrix may comprise entries denoting preferences of users with respect to content items. Confidence values associated with the fraction of user data may be configured as zero to block influence of the fraction of user data on performance of the recommendation model. The unlearning process may be implemented by performing a number of iterations until the recommendation model has converged.

Abstract: An in vitro release test (IVRT) method and system is provided for drug release testing. The IVRT method, referred to herein as adaptive perfusion, employ tangential-flow filtration (TFF), where released drug products that are smaller than a molecular weight cutoff (MWCO) of a membrane filter pass therethrough into the permeate. Unreleased drug products are retained by the pores of the filter and are recirculated to a retentate reservoir. Fresh media is provided to the retentate in order to maintain a constant total volume for the sample as well as to maintain sink conditions for the drug release. Drug concentration in the retentate and permeate are evaluated by in situ monitoring with one or more sensors and/or by periodic removal of aliquots from the respective reservoirs. In some embodiments, the membrane filter can be conditioned prior to use in order to improve the accuracy, precision, or both of the subsequent testing.
