Hi  ,

Thanks for your message. Can you confirm you’re using ‘metric’: ‘CS’ in your definition to assign cosine similarity?

And can you give us some more information to we can try recreate this?

• index config
• server version
• client version
• descriptive stats on inserted data data (dimension, outliers, presence of constant vectors)
• descriptive stats on query data data (dimension, outliers, presence of constant vectors)
• are there any outlier values in the data

Would also like to know

• if indexes look off or is it just distances
• how far off 1/-1 are distances

Feel free to email me lkerr@kx.com,  or send me a DM in the community if you’d prefer to.

Thanks,

Laura
