WebDec 7, 2024 · The answer is that we utilize the final layer in our siamese network implementation, which is sigmoid activation function. The sigmoid activation function has an output in the range [0, 1], meaning that when we present an image pair to our siamese network, the model will output a value >= 0 and <= 1. dark couch light coffee tablesWebHere is a schema from a super medium link to understand and apply a classic Siamese Network with Tensorflow.
