NASimEmu: Network Attack Simulator & Emulator for Training Agents Generalizing to Novel Scenarios

2 code implementations26 May 2023 Jaromír Janisch, Tomáš Pevný, Viliam Lisý

Current frameworks for training offensive penetration testing agents with deep reinforcement learning struggle to produce agents that perform well in real-world scenarios, due to the reality gap in simulation-based frameworks and the lack of scalability in emulation-based frameworks.

Symbolic Relational Deep Reinforcement Learning based on Graph Neural Networks and Autoregressive Policy Decomposition

1 code implementation25 Sep 2020 Jaromír Janisch, Tomáš Pevný, Viliam Lisý

We focus on reinforcement learning (RL) in relational problems that are naturally defined in terms of objects, their relations, and object-centric actions.

Classification with Costly Features in Hierarchical Deep Sets

1 code implementation20 Nov 2019 Jaromír Janisch, Tomáš Pevný, Viliam Lisý

In this work, we extend an existing deep reinforcement learning-based algorithm with hierarchical deep sets and hierarchical softmax, so that it can directly process this data.

Classification with Costly Features as a Sequential Decision-Making Problem

2 code implementations5 Sep 2019 Jaromír Janisch, Tomáš Pevný, Viliam Lisý

This work focuses on a specific classification problem, where the information about a sample is not readily available, but has to be acquired for a cost, and there is a per-sample budget.

Classification with Costly Features using Deep Reinforcement Learning

1 code implementation20 Nov 2017 Jaromír Janisch, Tomáš Pevný, Viliam Lisý

We study a classification problem where each feature can be acquired for a cost and the goal is to optimize a trade-off between the expected classification error and the feature cost.
