Abstract
Techniques are disclosed for debugging a neural network execution through operation backtracking. Operations of a neural network may be executed using an array of processing elements based on an input feature map to generate an output value of an output feature map. The operations may also be executed using a reference processor based on the input feature map to generate a reference output value. A first set of operations may be identified that relate a first set of contributing values of a first intermediary feature map to the output value. A second set of operations may be identified that relate a second set of contributing values of a second intermediary feature map to the first set of contributing values. The second set of contributing values may be compared to a second set of reference contributing values to detect a computation error related to the neural network execution.
