Accurate Deep Representation Quantization with Gradient Snapping Layer for Similarity Search

30 Oct 2016Shicong LiuHongtao Lu

Recent advance of large scale similarity search involves using deeply learned representations to improve the search accuracy and use vector quantization methods to increase the search speed. However, how to learn deep representations that strongly preserve similarities between data pairs and can be accurately quantized via vector quantization remains a challenging task... (read more)
