Re: N-dimensional Point Indexing

If you need them for scoring, then the natural choice would be to encode them in a BinaryDocValuesField. How do you plan to filter on these filter vectors? This is too many dimensions for points and doc values are not good at filtering. On Thu, Oct 18, 2018 at 2:32 AM Ken Krugler wrote: > > I’ve

Re: N-dimensional Point Indexing

I’ve been looking at directly storing feature vectors and providing scoring/filtering support. This is for vectors consisting of (typically 300 - 2048) floats or doubles. It’s following the same pattern as geospatial support - so a new field type and query/parser, plus plumbing to hook it into

Hi Lucene community, Is BinaryPoint limited up to 8 dimensions? Thanks, Luis Em 6 de fev de 2018 16:07, "Luís Filipe Nassif" escreveu: Is it limited up to 8 dimensions as described at https://www.elastic.co/blog/lucene-points-6.0? 2018-02-06 15:35 GMT-02:00 Luís Filipe Nassif : > Sorry, I wa

Re: N-dimensional Point Indexing

Sorry, I was looking at the wrong place. Should I use BinaryPoint ( https://lucene.apache.org/core/6_0_0/core/org/apache/lucene/document/BinaryPoint.html) ? 2018-02-06 14:17 GMT-02:00 Luís Filipe Nassif : > Hi all, > > Lucene is able to index generic n-dimensional points for efficient > similarit

N-dimensional Point Indexing

Hi all, Lucene is able to index generic n-dimensional points for efficient similarity or nearest neightbors search? I have looked at spatial package in the past but seems it is specific to geo points? The use case is to index image feature vectors to search for similar images in a corpus. Current
