Siamese Network

Siamese networks are a type of neural network that is used to compare two or more inputs and determine their similarity or dissimilarity. They are often used for tasks such as face recognition, image retrieval, and natural language processing.

How Siamese Networks Work

Siamese networks consist of two or more identical subnetworks that share the same weights. These subnetworks are typically convolutional neural networks (CNNs), which are designed to extract features from images. The inputs to the Siamese network are two or more images, which are passed through the subnetworks.

The outputs of the subnetworks are then compared using a distance metric, such as the Euclidean distance or the cosine similarity. The distance metric measures the similarity or dissimilarity of the two inputs. The Siamese network is trained to minimize the distance between similar inputs and maximize the distance between dissimilar inputs.

Applications of Siamese Networks

Siamese networks have a wide range of applications, including:

• Face recognition: Siamese networks can be used to identify faces by comparing them to a database of known faces.
• Image retrieval: Siamese networks can be used to retrieve similar images from a large database of images.
• Natural language processing: Siamese networks can be used to compare text documents and determine their similarity or dissimilarity.
