Learning to Infer User Hidden States for Online Sequential Advertising

Nancy J. Delong

In on the web promotion, the optimization of the promotion method is important. Though only knowing click on and buy steps, it is essential to predict user psychological states or intents.

A recent examine released on arXiv.org indicates applying current advances of deep learning methods to interpret the consumer’s psychological states. The likelihood of these hidden states is believed by learning from big-scale authentic-globe details, in its place of aggregating the consumer’s historical behaviors straightforwardly.

Depending on the user browsing actions, the customers’ psychological condition is determined as awareness, curiosity, or look for condition. Then, attainable condition transitions are believed and the promotion method which sales opportunities to the biggest reward is chosen. In the course of an experiment in the are living ad platform, nine.02 % far more earnings was generated with the exact spending budget price as opposed with a baseline method.

To travel buy in on the web promotion, it is of the advertiser’s wonderful curiosity to improve the sequential promotion method whose overall performance and interpretability are both critical. The absence of interpretability in existing deep reinforcement learning solutions can make it not effortless to have an understanding of, diagnose and further improve the method. In this paper, we propose our Deep Intents Sequential Promotion (DISA) strategy to tackle these troubles. The critical aspect of interpretability is to have an understanding of a consumer’s buy intent which is, even so, unobservable (termed hidden states). In this paper, we model this intention as a latent variable and formulate the problem as a Partially Observable Markov Selection Method (POMDP) exactly where the underlying intents are inferred dependent on the observable behaviors. Significant-scale industrial offline and on the web experiments show our method’s top-quality overall performance above several baselines. The inferred hidden states are analyzed, and the final results show the rationality of our inference.
