> Project: Ignite
> Issue Type: Improvement
> Components: ml
> Reporter: Aleksey Zinoviev
> Assignee: Aleksey Zinoviev
> Priority: Major
>
> The main idea to add a few strategies of indexing: sorting and so on.
> Currently it supports only one strategy (most popular with zero and less popular with the max index size).
> There are can be a few options
> * 'frequencyDesc': descending order by label frequency (most frequent label assigned 0)
> * 'frequencyAsc': ascending order by label frequency (least frequent label assigned 0)
>
> Please, update the method **transformFrequenciesToEncodingValues and add the strategy as a parameter of trainer.
