WebFrom the lesson. Siamese Networks. Learn about Siamese networks, a special type of neural network made of two identical networks that are eventually merged together, then build your own Siamese network that identifies question duplicates in a dataset from Quora. Week Introduction 0:46. Siamese Networks 2:56. Architecture 3:06. Cost Function 3:19. WebInstead, the Siamese network can determine if two images are in the same class. The network does this by reducing the dimensionality of the training data and using a distance-based cost function to differentiate between the classes. This example uses a Siamese network for dimensionality reduction of a collection of images of handwritten digits.
