Unequal Error Protection Querying Policies for the Noisy 20 Questions Problem

2017 · IEEE Transactions on Information Theory

In this paper, we propose an open-loop unequal-error-protection querying policy based on superposition coding for the noisy 20 questions problem. In this problem, a player wishes to successively refine an estimate of the value of …

Graph Filters and the <italic>Z</italic>-Laplacian

2017 · IEEE Journal of Selected Topics in Signal Processing

In network science, the interplay between dynamical processes and the underlying topologies of complex systems has led to a diverse family of models with different interpretations. In graph signal processing, this is manifested in the …

On Generating Characteristic-rich Question Sets for QA Evaluation

2016

We present a semi-automated framework for constructing factoid question answering (QA) datasets, where an array of question characteristics are formalized, including structure complexity, function, commonness, answer cardinality, and paraphrasing. Instead of collecting questions and manually …
