Weight-shifting mechanism for convolutional neural networks
Ayose Falcón,Marc Lupon,Herrero Abellanas Enric,Pedro Lopez,Fernando Latorre,Frederico Pratas,Georgios Tournavitis +6 more
TL;DR: A processor includes a processor core and a calculation circuit as discussed by the authors, which includes logic to determine a set of weights for use in a convolutional neural network (CNN) calculation and scale up the weights using a scale value.
Proceedings ArticleDOI
Fine-grain Parallelism Using Multi-core, Cell/BE, and GPU Systems: Accelerating the Phylogenetic Likelihood Function
TL;DR: This paper focuses on exploiting fine-grain parallelism for a demanding Bioinformatics application - MrBayes - and its Phylogenetic Likelihood Functions (PLF) using different architectures and general-purpose multi-core processors prove to be simpler to program and provide the best balance between an efficient parallel and serial execution.
Patent

Method and apparatus for distributed and cooperative computation in artificial neural networks
Frederico Pratas,Ayose Falcón,Marc Lupon,Fernando Latorre,Pedro Lopez,Enric Herrero Abellanas,Georgios Tournavitis +6 more
TL;DR: In this paper, an apparatus and method for distributed and cooperative computation in artificial neural networks is described, which comprises an input/output (I/O) interface, a plurality of processing units communicatively coupled to the I/O interface to receive data for input neurons and synaptic weights associated with each of the input neurons, each unit processing at least a portion of the data for the inputs and weights to generate partial results.
