Role of normalization By transforming the input of the hidden layer to a distribution with mean value of 0 and variance of 1, it is ensured that the input distribution of each layer will not cause excessive jitter due to the different distribution of different mini batches. It avoids that the network parameters need to […]

Introduction:This paper will introduce hologres’s implementation of ultra-high cardinality UV calculation based on roaringbitmap Roaringbitmap is a compressed bitmap index. Its data compression and de duplication features are very suitable for UV computing under big data. The main principles are as follows: For 32bit number, roaringbitmap will construct 2 ^ 16 buckets, corresponding to the […]

Squeezenet series is an early and classic lightweight network. Squeezenet uses fire module for parameter compression, and squeezenext adds separation convolution to improve it. Although the squeezenet series is not as widely used as mobinet, its architecture idea and experimental conclusions can be used for reference.

Shufflenet series is a very important series in lightweight networks. Shufflenetv1 puts forward channel shuffle operation, so that the network can use packet convolution to accelerate, while shufflenetv2 pushes down most of the designs of V1, puts forward channel split operation from reality, accelerates the network and reuses features at the same time, and achieves […]
