Abstract: Systems and techniques are provided for a ranking approach to train deep neural nets for multilabel image annotation. Label scores may be received for labels determined by a neural network for training examples. Each label may be a positive label or a negative label for the training example. An error of the neural network may be determined based on a comparison, for each of the training examples, of the label scores for positive labels and negative labels for the training example and a semantic distance between each positive label and each negative label for the training example. Updated weights may be determined for the neural network based on a gradient of the determined error of the neural network. The updated weights may be applied to the neural network to train the neural network.

Abstract translation: 提供系统和技术用于排列方法来训练用于多标签图像注释的深层神经网络。 可以接收由用于训练示例的神经网络确定的标签的标签分数。 每个标签可能是培训示例的正标签或负标签。 可以基于针对训练样本的正标签的标签分数和训练样本的负标签的每个训练样本的比较以及训练样本的每个正标签和每个负标签之间的语义距离来确定神经网络的误差 例。 可以基于确定的神经网络的误差的梯度来确定神经网络的更新权重。 更新的权重可以应用于神经网络来训练神经网络。

Abstract: Separately optimizing angle error and magnitude error of a search query entered into a query database may be referred to as the “shape-gain” separation quantization. Each of a direction and a magnitude for each of a plurality of database vectors may be separately encoded. A query vector may be received. The query vector may include a query direction and a query magnitude. The separately encoded query direction, query magnitude, and each of the separately encoded direction and magnitude for each of the plurality of database vectors may be combined. Distances between the query vector and each of the plurality of database vectors may be determined. At least one of the plurality of database vectors that is similar to the query vector may be identified based on the determined distances.

Abstract translation: 单独优化输入查询数据库的搜索查询的角度误差和幅度误差可以称为“形状增益”分离量化。 可以分别编码多个数据库向量中的每一个的方向和幅度的每一个。 可以接收查询向量。 查询向量可以包括查询方向和查询量级。 可以组合用于多个数据库向量中的每一个的单独编码的查询方向，查询量级以及单独编码的方向和幅度中的每一个。 可以确定查询向量与多个数据库向量中的每一个之间的距离。 可以基于所确定的距离来识别类似于查询向量的多个数据库向量中的至少一个。
