In this work, we develop a general framework for modeling set-valued data in continuous-time, compatible with any intensity-based recurrent neural point process model.

Given a pre-trained classifier and multiple human experts, we investigate the task of online classification where model predictions are provided for free but querying humans incurs a cost.

Deep, overparameterized regression models are notorious for their tendency to overfit.

Continuous-time event sequences, i. e., sequences consisting of continuous time stamps and associated event types ("marks"), are an important type of sequential data with many applications, e. g., in clinical medicine or user behavior modeling.

In reasoning about sequential events it is natural to pose probabilistic queries such as "when will event A occur next" or "what is the probability of A occurring before B", with applications in areas such as user modeling, medicine, and finance.

Since practitioners face speed versus accuracy tradeoffs in these models, variational inference (VI) is often the preferable option.

We consider the problem of online learning in the presence of distribution shifts that occur at an unknown rate and of unknown intensity.

Modeling such data can be very challenging, in particular for applications with many different types of events, since it requires a model to predict the event types as well as the time of occurrence.

This work introduces the Generative Conversation Control model, an augmented and fine-tuned GPT-2 language model that conditions on past reference conversations to probabilistically model multi-turn conversations in the actor's persona.
