Abstract
We present the third version of the MemoriEase lifelog retrieval
system. This system is a conversational lifelog retrieval system built
on an embedding-based retrieval method. For LSC’25, we enhance
our system with a RAG approach to the question-answering task.
In addition, we also incorporate two embedding models, CLIP and
BLIP2, for the embedding-based retrieval. We improve our relevance feedback for visual similarity search by adjusting the query
embedding. We describe the results of our system at the LSC’25
challenge, where it achieved third place overall and second place
in the QA task. The enhancements in this version of the system
improve our performance in the LSC’25 challenge.
