1. A neurosynaptic system comprising:
- a first set of hardware neurosynaptic core circuits configured to;
receive input data comprising different input regions, wherein the input data comprises at least one of audio data or visual data; and
extract a first set of features from the input data, wherein features of the first set are computed based on the different input regions; and
a second set of hardware neurosynaptic core circuits configured to;
receive the first set of features; and
generate output data comprising a second set of features, wherein the second set of features are linear combinations computed by combining the first set of features based on synaptic connectivity information of the second set of hardware neurosynaptic core circuits, and each feature of the second set of features represents a characteristic across the different input regions;
wherein the output data is provided to a classifier comprising a third set of hardware neurosynaptic core circuits for object classification, the classifier configured to classify each object of interest within the input data based on the output-data; and
wherein each hardware neurosynaptic core circuit comprises a plurality of electronic neurons, a plurality of electronic axons, and a plurality of electronic synapses for interconnecting the neurons with the axons.

Abstract
Embodiments of the invention provide a neurosynaptic system comprising a first set of one or more neurosynaptic core circuits configured to receive input data comprising multiple input regions, and extract a first set of features from the input data. The features of the first set are computed based on different input regions. The system further comprises a second set of one or more neurosynaptic core circuits configured to receive the first set of features, and generate a second set of features by combining the first set of features based on synaptic connectivity information of the second set of core circuits.
