Formatting of results column

[sjoerdvansteenkiste]

Currently floats that are displayed in the results column are not clipped up to a fixed decimal point. I.e. currently I see the following:

0.773208737373352,0.8946895003318787,2824.651123046875

and I would suggest something along the lines of

0.77,0.89,2824.65

Moreover, when saving multiple results in a list (as is the case in the above example) it would be nice to add some spacing.

0.77, 0.89, 2824.65

Hi,
thank for your idea. I originally expected the result field to contain only a single number but now I see it's not enough.

• Regarding clipping, the question is how to determine the number of digits to show.
• Spacing is obvious (for arrays), some formatting would be nice.

What about adding the result as a browsable element similarly to info or config in the run detail view?

I would have similar requirements like @sjoerdvansteenkiste , because I usually compute one or more metrics in addition to the cost-function. Unfortunately, It looks like sacredboard can only display a single scalar value in the list right now. Or am I missing something?

I tried to return a dictionary instead of a scalar, but this is only displayed as "object Object" and it is not possible to see values contained in the dictionary. Even when I return a dictionary with just a 'optimization_target' value, which is recommended when using labwatch also leads to the problem that no result value is shown in the table.
Returning multiple values as a list is a bad workaround in my opinion, because sorting of the "Results" column might then not be possible anymore.

My suggestion:

• when only a single value is returned
  • store the value in the results column
• when a dictionary is returned:
  • store the key "optimization_target" in the result column (to be compatible with sacred's labwatch extension)
  • create a new result column for every other key in the dictionary
• optional: when a list is returned:
  • Create a column for every value: Result, Result2, Result3, ...

This would have the advantage than you can sort the results according to every result. As an example, an experiment could return the following:

• loss
• metrics (accuracy, recall, precission)
• steps / epochs (how long did the training run until it was stopped due to the stopping criteria)

I am also interested in such a feature.

@bsautermeister: This will make the number of columns dynamic and it could be huge if you return too many values. Even though sorting regarding results would be nice.

The problem I see as well, is that not all your experiments might have the same result dictionary, so many columns would be empty.

Generally, I think that issue #24 does answer your problem and would be more generic.

The results should then be saved as @chovanecm proposed above:

Ok, so this looks like something that is really wanted.
For now, I would stay with the detail view similar to config view.

May I ask some of you to attach an experiment with such result structure to this ticket?

[chovanecm]

Should be done together with #24

[chovanecm]

At least the first step is done: result is now listed in the detail view and can be rendered properly for both complex and scalar values.
