I'm a PhD student at the University of Amsterdam, working with Marcel Worring and Yuki Asano. I work on vision and language learning at the Informatics Institute, where I'm part of MultiX Amsterdam and AIMLab groups. In 2023 I spent time as a Research Scientist Intern in Meta GenAI, working on image generation and in-context learning. I obtained my master degree in Artificial Inteligence at the KU Leuven. Before that, I spent some time as a Software Engineer in Netcetera and I was an undergraduate student in Computer Science and Engineering at the FCSE at University ”Ss. Cyril and Methodius” in Skopje. Email / Twitter / Google Scholar / Github / LinkedIn |

My research is at the intersection of vision and language learning - with focus on designing efficient approaches for multimodal understanding and generative tasks. I'm interested in better understanding what large-scale models learn, and how to exploit that through in-context learning and prompting. Some of my work also includes automated linguistic interpretation of images, as well as its applications in the medical domain. |

Ivona Najdenkoska, Xiantong Zhen, Marcel Worring In ICLR 2023 paper | code We propose a method for bridging large-scale vision and language models to perform multimodal few-shot learning. The model meta-learns visual prefixes from frozen visual backbone, which are used as prompts to a large langauge model. |

Tom van Sonsbeek*, Mohammad M. Derakshani*, Ivona Najdenkoska*, Cees Snoek, Marcel Worring In MICCAI 2023, Oral paper | code We introduce a novel method for open-ended VQA suited for small, domain-specific, medical datasets. We employ parameter-efficient strategies for efficient tuning of the LMs. |

Ivona Najdenkoska, Xiantong Zhen, Marcel Worring, Ling Shao In Medical Image Analysis 2022, Best Paper Honorable Mention paper | code We present a probabilistic latent variable model for chest X-Ray report generation. We extend the VTI model by providing a fully Transformer-based definition and explore the trade-off between an LSTM- or Transformer-based decoder for generation of medical text. |

Ivona Najdenkoska, Xiantong Zhen, Marcel Worring, Ling Shao In MICCAI 2021, Oral + Travel Award paper | code We propose Variational Topic Inference (VTI), a probabilistic latent variable model for automatic report generation. We introduce a set of topics as latent variables to guide sentence generation by aligning image and language modalities in the latent space. |
