摘要:

正如语义哈希可以加速信息检索一样,二进制值嵌入可以显著减少图形数据检索的延迟。我们引入一个简单但有效的模型来学习图中节点的二进制向量。通过将嵌入想象为具有不同偏差的独立硬币翻转,可以将连续优化技术应用于近似的预期损失。以这种方式优化的嵌入在各种数据集的排名和预排名任务上始终优于谱图嵌入和各种学习的实值嵌入的量化。

英文摘要:

Just as semantic hashing can accelerate information retrieval, binary valued embeddings can significantly reduce latency in the retrieval of graphical data. We introduce a simple but effective model for learning such binary vectors for nodes in a graph. By imagining the embeddings as independent coin flips of varying bias, continuous optimization techniques can be applied to the approximate expected loss. Embeddings optimized in this fashion consistently outperform the quantization of both spectral graph embeddings and various learned real-valued embeddings, on both ranking and pre-ranking tasks for a variety of datasets.
