Abstract: A connection between a user device and a network server is established. Via the connection, a deep learning network is formed for a processing task. A first portion of the deep learning network operates on the user device and a second portion of the deep learning network operates on the network server. Based on cooperation between the user device and the network server, a boundary between the first portion and the second portion of the deep learning network is dynamically modified based on a change in a performance indicator that could affect the processing task.

Abstract: First and second data representation are stored in first and second blocks of a non-volatile, solid-state memory. The first and second blocks share series-connected bit lines. The first and second blocks are selected and other blocks of the non-volatile, solid-state memory that share the bit lines are deselected. The bit lines are read to determine a combination of the first and second data representations. The combination may include a union or an intersection.
