Abstract: Injecting generated data samples into a minority data class of an imbalanced training data set is provided. In response to receiving an input to balance the imbalanced training data set that includes a majority data class and the minority data class, a set of data samples is generated for the minority data class. A distance is calculated from each data sample in the set of generated data samples to a center of a kernel that includes a set of data samples of the majority data class. Each data sample in the set of generated data samples is stored within a corresponding distance score bucket based on the calculated distance of a data sample. Generated data samples are selected from a number of highest ranking distance score buckets. The generated data samples selected from the number of highest ranking distance score buckets are injected into the minority data class.

Abstract: A server and/or a client stores a metadata hash map that includes one or more entries associated with keys for data records stored in a cache on a server, wherein the data records comprise a directed acyclic graph (DAG), and the directed acyclic graph is comprised of a collection of one or more nodes connected by one or more edges, each of the nodes representing one or more tasks ordered into a sequence, and each of the edges representing one or more constraints on the nodes connected by the edges. Each of the entries stores metadata for a corresponding data record, wherein the metadata comprises a server-side remote pointer that references the corresponding data record stored in the cache.
