Abstract: Weighted population code for efficient data representation in neuromorphic systems. Input value is represented by spikes on axons, each of which has an associated weight. Weighted spikes are integrated/added, which may be over over multiple ticks, to give the input value. Requires less hardware for greater dynamic range compared to prior art. Can be converted to stochastic code by dividing value by size of dynamic range. Also disclosed is stochastic code corelet 206 on neuromorphic chip 205. Pre-processor 202 encodes input data to weighted population code for transfer onto neuromorphic chip, and corelet translates input to stochastic code for use by classifiers also on chip. This reduces the input bandwidth of the chip. Also disclosed is delaying sending of spikes to a neuron during a preload period. The spikes then affect the neuron during a subsequent setup period, before the neuron produces output. This means that input can be sent while the neuron is still producing the previous output, which reduces setup time and shortens processing cycle.

Abstract: Weighted population code in neuromorphic systems is provided. According to an embodiment, a plurality of input values is received. For each of the plurality of values, a plurality of spikes is generated. Each of the plurality of spikes has an associated weight. A consumption time is determined for each of the plurality of spikes. Each of the plurality of spikes is sent for consumption at its consumption time.

Abstract: Providing document access control based on document component layouts, a processor detects a layout of a document, the layout including one or more components of the document. The components maybe tables, figures, paragraphs and specific document sections. A processor defines an access policy to access the one or more components based on the layout. A processor authorizes a request to access the one or more components based on the access policy and the layout. A processor retrieves the one or more components based on the access policy and the authorized request, where retrieving the one or more components includes displaying them based on the access level. A layout similarity maybe determined between the document and a second document and based on a similarity threshold dynamically applying the access policy to the second document to retrieve a component of a second document based on the access policy.
