In this paper, we propose Aggregation-based Graph Convolutional Hashing (AGCH) to tackle these obstacles. First, considering that a single similarity metric can hardly represent data relationships comprehensively, we develop an efficient aggregation strategy that utilises multiple metrics to construct a ...
If φ 2 = φ 2 = 1 then based on properties of count sketches in §3, we have K K P†Pφ, φ = Pφ, Pφ ∼N φ, φ , σ†2 , (13) where φ, φ is a point-wise convolution of feature vector φ with convolutional filter φ . It f...
