why batched_weighted_sum?

[joyousrabbit]

Hello, why use batched_weighted_sum instead of direct dot on all items?

[mhattingpete]

I believe its due to a dot product with large vectors could cause memory overflow so instead the use a way of looping through batches of data and computing the dot product

Yea the output is the same regardless of batch size, so probably what @mhattingpete said
