Title: Circuitry for providing an output voltage
Inventor: JOHN BRUCE BOWLERWELL
IPC: H03F1/52
Filed: 2020-05-20
Abstract: Circuitry for providing an output voltage to a load connected to node 120 comprises a voltage generator such as amplifier 110, a current limiter circuit such as controllable switch 140a, a circuit to detect when the load voltage reaches a target voltage and a delay circuit to deactivate the current limiting a delay period after the target voltage is reached. Amplifier 110 providing the voltage may be dynamically reconfigurable to operate in a second of two modes when the current limiter has been activated. The second amplifier mode may compensate for the absence of a load coupled to its output by adjustment of a parameter such as power consumption, noise, accuracy, stability or output voltage. Logic circuitry 920 may switch the amplifier to the second mode when current limitation is active at any of plural output nodes and switch it to a normal or default mode when current limit is disabled at a node. Controllable switch 140 may be a MOSFET that operates in either a current limiting mode or a fully on mode, the current limiter may comprise a current mirror and the delay circuit may comprise analogue or digital circuitry.

Title: Feature engineering in neural networks optimization
Inventor: CRAIG TRIM
IPC: G06N20/00
Filed: 2020-06-12
Abstract: A transitive closure data structure is constructed for a pair of features represented in a vector space corresponding to an input dataset. The data structure includes a set of entries corresponding to a set of all possible paths between a first feature in the pair and a second feature in the pair in a graph of the vector space. The data structure is reduced by removing a subset of the set of entries such that only a single entry corresponding to a single path remains in the transitive closure data structure. A feature cross is formed from a cluster of features remaining in a reduced ontology graph resulting from the reducing the transitive closure data structure. A layer is configured in a neural network to represent the feature cross, which causes the neural network to produce a prediction that is within a defined accuracy relative to the dataset.
