WebFirst, we adopt the Gumbel- softmax [11] trick to make the retrieval process differentiable, thus enable op- timizing the embedding through the end-to-end training. Second, we design an iterative retrieval process to select a set of compatible patches (i.e., objects) for synthesizing a single image. Webducing the complexity of the softmax function to O(p N) without signiﬁcantly compromising on accuracy [16]. This approach uses Gumbel random variables, a Maximum In-ner Product Search (MIPS) data structure and random sam-pling to estimate an O(p N) sized subset of the dataset for use in estimating the output of the softmax function. With
