Doctoral defence of Federico Malato, MSc, 15.12.2025: Enhancing decision making with retrieval-learning hybrid agents MSc Federico Malato's doctoral dissertation explores a novel approach to augment decisions made by autonomous agents via active recall of past experiences.

Belated congratulations to Dr Federico Malato, one of the most active members of our StatML group, on earning his PhD on 15 Dec 2025! 👏🚀🎉

His dissertation explores retrieval learning hybrid agents: using a memory module + search to actively recall past experiences and improve decision making.

Generalizable speech deepfake detection via meta-learned LoRA Reliable detection of speech deepfakes (spoofs) must remain effective when the distribution of spoofing attacks shifts. We frame the task as domain generalization and show that inserting Low-Rank Adap...

Targeted Fine-Tuning of DNN-Based Receivers via Influence Functions We present the first use of influence functions for deep learning-based wireless receivers. Applied to DeepRx, a fully convolutional receiver, influence analysis reveals which training samples drive b...

1) “Targeted Fine-Tuning of DNN-Based Receivers via Influence Functions” by Tuononen, Penttinen, Hautamäki (StatML) arxiv.org/abs/2509.15950

Influence functions pinpoint the training samples behind bit decisions, enabling targeted fine-tuning that improves BER (single-target > random).
