ICCV 20192019We propose a novel approach for estimating the difficulty and transferability of supervised classification tasks. Unlike previous work, our approach is solution agnostic and does not require or assume trained models. Instead, we estimate these values using an information-theoretic approach: treating training labels as random variables and exploring their statistics. When transferring from a source to a target

KDD AdKDD 20192019We apply and extend recent results in feasible arm identification to quickly find a small set of bidding strategies that can simultaneously meet multiple business objectives. We formulate this as an any-m feasible arm identification problem, a pure exploration multi-armed bandit problem where each arm is a D-dimensional distribution represented by a mean vector. The goal is to identify m feasible arms,meaning

EMNLP 20192019Research in the social sciences and psychology has shown that the persuasiveness of an argument depends not only the language employed, but also on attributes of the source/communicator, the audience, and the appropriateness and strength of the argument’s claims given the pragmatic and discourse context of the argument. Among these characteristics of persuasive arguments, prior work in NLP does not explicitly

NeurIPS 20192019Motivated by the many real-world applications of reinforcement learning (RL) that require safe-policy iterations, we consider the problem of off-policy evaluation (OPE) — the problem of evaluating a new policy using the historical data obtained by different behavior policies — under the model of nonstationary episodic Markov Decision Processes with a long horizon and large action space. Existing importance

NeurIPS 2019 Workshop on Conversational AI2019Training dialog policies for speech-based virtual assistants requires a plethora of conversational data. The data collection phase is often expensive and time consuming due to human involvement. To address this issue, a common solution is to build user simulators for data generation. For the successful deployment of the trained policies into real world domains, it is vital that the user simulator mimics
