Engineering Efficient Self-Play Chess: Search, Replay, and Throughput Under Limited Compute
Bertil Braun
How strong can an AlphaZero-style chess system become under limited training compute when its entire learning loop is engineered for efficiency? We train from random initialization…
Identity-Consistent Analysis of Long-Shot Windsurfing Video: A Domain-Specific Offline Tracking System
Bertil Braun
Long-shot windsurfing video combines small targets, large camera pans, prolonged overlaps, and rapidly changing backgrounds. The desired output is not a generic MOT trace but a sep…
Voice-Light: A Full-Duplex Cascaded Voice Agent with Causal Turn-Taking and Speculative Generation
Bertil Braun
Natural spoken interaction requires more than streaming ASR, language generation, and speech synthesis: a system must react to overlap without canceling on every acknowledgment, pr…
(Towards) Scalable Reliable Automated Evaluation with Large Language Models
Bertil Braun, Martin Forell
Evaluating the quality and relevance of textual outputs from Large Language Models (LLMs) remains challenging and resource-intensive. Existing automated metrics often fail to captu…
A Graph-Based Control Interface for Traffic Signals on Heterogeneous Road Networks
Bertil Braun
We present a traffic-signal control interface in which a shared graph neural network assigns scores to individual traffic movements. Each junction converts these scores into its ow…
