This PR uses (number of actual table) weighted average instead of
average without weights for table metrics.
- pages where there are ground truth tables the weight is proportional
to the number of ground truth tables in that page
- pages where there are no ground truth tables but has predicted tables
(false positive) are assigned as 1 table worth of weight for the whole
page for calculating the mean value of `table_level_acc`
- pages with false positive tables do not contribute to table structural
or table content metrics
## test
This PR updates the existing test for evaluating table metrics:
- adds a second file with just 1 table vs. the existing file with 2
tables
- test the weighted average is written to the report
The sample docs directory contains the following files:
example-10k.html - A 10-K SEC filing in HTML format
layout-parser-paper.pdf - A PDF copy of the layout parser paper
factbook.xml/factbook.xsl - Example XML/XLS files that you can use to test stylesheets
These documents can be used to test out the parsers in the library. In addition, here are
instructions for pulling in some sample docs that are too big to store in the repo.
