NEU: A Meta-Algorithm for Universal UAP-Invariant Feature Representation [article]

Anastasis Kratsios, Cody Hyndman
2021 arXiv   pre-print
We show that NEU can learn any feature map with these two properties if that feature map is asymptotically deformable into the identity.  ...  This paper introduces a meta-procedure, called Non-Euclidean Upgrading (NEU), which learns feature maps that are expressive enough to embed the universal approximation property (UAP) into most model classes  ...  The authors thank Alina Stancu (Concordia University) for helpful discussions, Josef Teichmann and the entire working group at ETH for their helpful feedback, and Behnoosh Zamanlooy for the Python guidance  ...

Smoothing Policies and Safe Policy Gradients [article]

Matteo Papini, Matteo Pirotta, Marcello Restelli
2022 arXiv   pre-print
Policy Gradient (PG) algorithms are among the best candidates for the much-anticipated applications of reinforcement learning to real-world control tasks, such as robotics.  ...  Through a joint, adaptive selection of these meta-parameters, we obtain a policy gradient algorithm with monotonic improvement guarantees.  ...  The authors would like to thank Gergely Neu for his suggestions on how to improve the Safe Policy Gradient algorithm and its theoretical analysis.  ...

Introduction to Online Convex Optimization [article]

Elad Hazan
2021 arXiv   pre-print
In many practical applications the environment is so complex that it is infeasible to lay out a comprehensive theoretical model and use classical algorithmic theory and mathematical optimization.  ...  It is necessary as well as beneficial to take a robust approach, by applying an optimization method that learns as one goes along, learning from experience as more aspects of the problem are observed.  ...  I am very thankful to Wouter Koolen-Wijkstra for a helpful suggestion in the analysis of the Online Newton Step algorithm.  ...

Entity Retrieval and Text Mining for Online Reputation Monitoring [article]

Pedro Saleiro
2018 arXiv   pre-print
Therefore, we address the problem of Entity-Relationship (E-R) retrieval in which the goal is to search for multiple connected entities.  ...  We argue that this format is too restrictive as end users often like to have the flexibility to search for entity-centric information that is not available in predefined charts.  ...  The framework is adaptable and can be reused in different application scenarios, such as finance and politics.  ...
