----------------------------------
Summary: DL: performance improvements to fit transition function
Key: MADLIB-1418
URL: https://issues.apache.org/jira/browse/MADLIB-1418
Project: Apache MADlib
Issue Type: Improvement
Components: Deep Learning
Reporter: Nikhil Kak
Fix For: v1.17
{{We can speed up our per row/buffer time by not serializing the model weights
as part of state except for the last row. For all rows except the last row, all
we need from the model state is just the agg_image_count, so we can just set
the state to agg_image_count for all rows except the last row. For the last
row, the behavior remains the same as before}}
{{}}
{{With places10 20 msts gpdb6 (with 1 epoch for all msts), per iteration time
went down from around 1700-1800 secs to 1600-1700 secs. }}
{{This will be more pronounced when training with a bigger dataset like
places365/imagenet.}}
