• Authors: Narges Tabari, Sandesh Swamy, Rashmi Gangadharaiah
• Abstract summary: We explore an automated approach to identifying user personas by leveraging high dimensional trajectory information from user sessions on webpages. Our method introduces SessionBERT, a Transformer-backed language model trained from scratch on the masked language modeling (mlm) objective. Our results show that representations learned through SessionBERT are able to consistently outperform a BERT-base model.

• Abstract: Providing a personalized user experience on information dense webpages helps users in reaching their end-goals sooner. We explore an automated approach to identifying user personas by leveraging high dimensional trajectory information from user sessions on webpages. While neural collaborative filtering (NCF) approaches pay little attention to token semantics, our method introduces SessionBERT, a Transformer-backed language model trained from scratch on the masked language modeling (mlm) objective for user trajectories (pages, metadata, billing in a session) aiming to capture semantics within them. Our results show that representations learned through SessionBERT are able to consistently outperform a BERT-base model providing a 3% and 1% relative improvement in F1-score for predicting page links and next services. We leverage SessionBERT and extend it to provide recommendations (top-5) for the next most-relevant services that a user would be likely to use. We achieve a HIT@5 of 58% from our recommendation model.

  We propose the Frequent Attribute Pattern Augmented Transformer (FAPAT) FAPAT characterizes user intents by building attribute transition graphs and matching attribute patterns. We demonstrate that FAPAT consistently outperforms state-of-the-art methods by an average of 4.5% across various evaluation metrics.

• Explainable Active Learning for Preference Elicitation [0.0]
  We employ Active Learning (AL) to solve the addressed problem with the objective of maximizing information acquisition with minimal user effort. AL operates for selecting informative data from a large unlabeled set to inquire an oracle to label them. It harvests user feedback (given for the system's explanations on the presented items) over informative samples to update an underlying machine learning (ML) model.

• Latent User Intent Modeling for Sequential Recommenders [92.66888409973495]
  Sequential recommender models learn to predict the next items a user is likely to interact with based on his/her interaction history on the platform. Most sequential recommenders however lack a higher-level understanding of user intents, which often drive user behaviors online. Intent modeling is thus critical for understanding users and optimizing long-term user experience.

  We develop a hierarchical Bayesian model termed ordinal graph factor analysis (OGFA), which jointly models user-item and user-user interactions. OGFA not only achieves good recommendation performance, but also extracts interpretable latent factors corresponding to representative user preferences. We extend OGFA to ordinal graph gamma belief network, which is a multi-stochastic-layer deep probabilistic model.

  Click-through rate (CTR) prediction, whose goal is to predict the probability of the user to click on an item, has become increasingly significant in recommender systems. Recent deep learning models with the ability to automatically extract the user interest from his/her behaviors have achieved great success. We propose a novel approach under the framework of the wrapper method, which is named Meta-Wrapper.

  In Machine Learning scenarios, privacy is a crucial concern when models have to be trained with private data coming from users of a service. We propose Federated Learning (FL) as a means to build ML models based on private datasets distributed over a large number of clients. A central coordinating server receives locally computed updates by clients and aggregate them to obtain a better global model.
