LeanVec: Searching vectors faster by making them fit

1 code implementation26 Dec 2023 Mariano Tepper, Ishwar Singh Bhati, Cecilia Aguerrebere, Mark Hildebrand, Ted Willke

In this work, we present LeanVec, a framework that combines linear dimensionality reduction with vector quantization to accelerate similarity search on high-dimensional vectors while maintaining accuracy.

The present work describes new probabilistic image analysis methods for single-synapse analysis of synapse populations in both animal and human brains.

Fundamental Limits in Multi-image Alignment

no code implementations4 Feb 2016 Cecilia Aguerrebere, Mauricio Delbracio, Alberto Bartesaghi, Guillermo Sapiro

In this work, we tackle the problem of finding the performance limits in image registration when multiple shifted and noisy observations are available.
