C-MCTS: Safe Planning with Monte Carlo Tree Search

1 code implementation25 May 2023 Dinesh Parthasarathy, Georgios Kontes, Axel Plinge, Christopher Mutschler

We propose Constrained MCTS (C-MCTS), which estimates cost using a safety critic that is trained with Temporal Difference learning in an offline phase prior to agent deployment.

Augmented Random Search for Multi-Objective Bayesian Optimization of Neural Networks

no code implementations23 May 2023 Mark Deutel, Georgios Kontes, Christopher Mutschler, Jürgen Teich

Deploying Deep Neural Networks (DNNs) on tiny devices is a common trend to process the increasing amount of sensor data being generated.

Efficient Beam Search for Initial Access Using Collaborative Filtering

no code implementations14 Sep 2022 George Yammine, Georgios Kontes, Norbert Franke, Axel Plinge, Christopher Mutschler

Our algorithm is based on a recommender system that associates groups (i. e., UEs) and preferences (i. e., beams from a codebook) based on a training data set.

Overcoming Catastrophic Forgetting via Hessian-free Curvature Estimates

no code implementations25 Sep 2019 Leonid Butyrev, Georgios Kontes, Christoffer Löffler, Christopher Mutschler

Learning neural networks with gradient descent over a long sequence of tasks is problematic as their fine-tuning to new tasks overwrites the network weights that are important for previous tasks.
