摘要:

在本文中,我们开发了一种新的推荐模型,明确地将时间信息。该模型依赖于嵌入层和TSL注意力机制,在不同的向量空间中具有内积,这可以被认为是多头注意力的修改。这种机制允许模型有效地处理不同长度的用户行为序列。我们研究我们的国家的最先进的模型的统计设计的数据集的属性。此外,我们表明,它优于更复杂的模型,更长的序列长度上的淘宝用户行为数据集。

英文摘要:

In this paper we develop a novel recommendation model that explicitly incorporates time information. The model relies on an embedding layer and TSL attention-like mechanism with inner products in different vector spaces, that can be thought of as a modification of multi-headed attention. This mechanism allows the model to efficiently treat sequences of user behavior of different length. We study the properties of our state-of-the-art model on statistically designed data set. Also, we show that it outperforms more complex models with longer sequence length on the Taobao User Behavior dataset.
