Krikri: Advancing Open Large Language Models for Greek

EMNLP 2025

We introduce Llama-Krikri-8B, a cutting-edge Large Language Model tailored for the Greek language, built on Meta’s Llama 3.1-8B. Llama-Krikri-8B has been extensively trained on high-quality Greek data to ensure superior adaptation to linguistic nuances. With 8 billion parameters, it offers advanced

Investigating Personalization Methods in Text to Music Generation

ICASSP 2024accepted

In this work, we investigate the personalization of text-to-music diffusion models in a few-shot setting. Motivated by recent advances in the computer vision domain, we are the first to explore the combination of pre-trained text-to-audio diffusers with two established personalization methods. We ex…

Adapted Multimodal Bert with Layer-Wise Fusion for Sentiment Analysis

ICASSP 2023accepted

Multimodal learning pipelines have benefited from the success of pretrained language models. However, this comes at the cost of increased model parameters. In this work, we propose Adapted Multimodal BERT (AMB), a BERT-based architecture for multimodal tasks that uses a combination of adapter module…

Multi-Scale Compositional Constraints for Representation Learning on Videos

ICASSP 2023accepted

Combining simple concepts to form structured thoughts and decomposing complex concepts into their constituents is one key characteristic of human cognition. In this work we extract video representations by combining multi-scale processing with compositional constraints, i.e., we constrain the latent…

ADMM-DAD Net: A Deep Unfolding Network for Analysis Compressed Sensing

ICASSP 2022accepted

In this paper, we propose a new deep unfolding neural network based on the ADMM algorithm for analysis Compressed Sensing. The proposed network jointly learns a redundant analysis operator for sparsification and reconstructs the signal of interest. We compare our proposed network with a state-of-the…

Mmlatch: Bottom-Up Top-Down Fusion For Multimodal Sentiment Analysis

ICASSP 2022accepted

Current deep learning approaches for multimodal fusion rely on bottom-up fusion of high and mid-level latent modality representations (late/mid fusion) or low level sensory inputs (early fusion). Models of human perception highlight the importance of top-down fusion, where high-level representations…

UDALM: Unsupervised Domain Adaptation through Language Modeling

NAACL 2021long

In this work we explore Unsupervised Domain Adaptation (UDA) of pretrained language models for downstream tasks. We introduce UDALM, a fine-tuning procedure, using a mixed classification and Masked Language Model loss, that can adapt to the target domain distribution in a robust and sample efficient…
