Abstract: This specification describes systems, apparatus and methods for deploying Tsetlin machine models on resource-constrained devices. According to a first aspect of this specification, there is described apparatus comprising: one or more sensors; at least one processor; and at least one memory with storing instructions that, when executed by the at least one processor, cause the apparatus at to at least: collect one or more sets of sensor data using the one or more sensors; classify the one or more sets of sensor data using an encoded Tsetlin machine. The encoded Tsetlin machine comprises a compressed representation of a trained Tsetlin machine. The compressed representation is based on a number of exclude decisions of the trained Tsetlin machine being greater than a number of include decisions of the trained Tsetlin machine.

Abstract: Example embodiments describe an apparatus, method and computer program relating to cancellation of ultrasonic signals. The apparatus may comprise means for providing first data derived from a signal received by a microphone of a user device and means for providing second data representing mechanical oscillations within a gyroscope of the user device. The apparatus may also comprise means for detecting, based on the first data and the second data, that the signal received by the microphone comprises an ultrasonic signal, means for processing third data to generate fourth data representing an estimate of one or more audible sounds in the first data, wherein the third data is either the second data or is derived from the second data, and means for subtracting the fourth data from the first data to provide fifth data.

Abstract: Examples of the disclosure relate to selecting candidate devices for connecting with one or more portable devices. In examples of the disclosure two or more candidate devices that satisfy location criteria are identified. Microphones of a portable device are used to determine a location of a sound source relative to the at least one portable device and the location of the sound source is compared with respective locations for the two or more candidate devices. A candidate device for connecting to the at least one portable device is selected based, at least in part, on the comparison between the location of the sound source and a location for the selected candidate device.
