Sony patents camera tech that tracks neural network activity to prevent errors
Sony describes an imaging device that uses a neural network to process images. It includes a unit that calculates statistics on the network's output signals over a specific time frame to monitor performance.
In the filing’s own words
To suppress performance degradation when sparsity is improved in an imaging device using a neural network. The imaging device includes a predetermined number of output-side neurons and a statistic calculation unit. In this imaging device, each of the output-side neurons generates an output signal on the basis of an input signal from an intermediate layer every time a predetermined unit time elapses. The statistic calculation unit performs, for each output-side neuron, a calculation of a statistic of the output signals generated within a predetermined frame period longer than the unit time.
What exactly they claim (claim 1)
1. An imaging device comprising a simple detector, wherein the simple detector includes a predetermined number of output-side neurons each configured to generate an output signal on the basis of an input signal from an intermediate layer every time a predetermined unit time elapses; and a statistic calculation unit configured to perform, for each of the output-side neurons, a calculation of a statistic of the output signals generated within a predetermined frame period longer than the unit time.
