# SiameseNet-Search

Search can be performed in various ways and using various architectures. In the following repository embeddings are created by using  an non-cnn **base embedding model** which is tuned using a *Siamese Neural Net*  with *Triplet Loss* inspired from [F. Schroff, D. Kalenichenko and J. Philbin, "FaceNet: A unified embedding for face recognition and clustering," 2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), Boston, MA, 2015, pp. 815-823.  ](https://arxiv.org/pdf/1503.03832.pdf) paper from Google , on **10K MNIST digits** images from train-set.The trained model is used to create embeddings for *entire* train-set and then Indexed using [Approx Nearest Neighbours](https://github.com/spotify/annoy) being faster than K-NN.

More like a prototype.

### Embedding Space Visualized

PCA used for visualizing the embedding space of **10K images** of different classes.
