Predicting data
Predicting data in this instance means predicting the argmax value. To do this, we assume that the last layer of the network is a SoftmaxLayer. Prediction occurs when we call the GetPrediction()
function, as follows:
public int[] GetPrediction(){var softmaxLayer = this._lastLayer as SoftmaxLayer<T>;if (softmaxLayer == null){throw new Exception("Function assumes softmax as last layer of the net!");}var activation = softmaxLayer.OutputActivation;var N = activation.Shape.Dimensions[3];var C = activation.Shape.Dimensions[2];var result = new int[N];for (varn = 0; n < N; n++){varmaxv = activation.Get(0, 0, 0, n);varmaxi = 0;for (vari = 1; i < C; i++){var output = activation.Get(0, 0, i, n);if (Ops<T>.GreaterThan(output, maxv))Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
