comment:20 Changed 3 years ago by gkronber
r17683: deleted branch
comment:21 Changed 3 years ago by gkronber
r17684: include correct files in .csproj
comment:22 Changed 3 years ago by gkronber
The problem instances provider should not be the default selected one. Instead CSV should be the default. Right now AI is ordered first.
comment:23 Changed 2 years ago by gkronber
Discovered problem instance providers are ordered by Name in ProblemView line 70:
problemInstanceProviderComboBox.DataSource = ProblemInstanceProviders.OrderBy(x => x.Name).ToList();
comment:24 Changed 2 years ago by gkronber
r17804: start Name of CVS instance provider with a space to make sure it is ordered first.
comment:25 Changed 2 years ago by gkronber
- Use the same noise levels and calculation as in our experiments for the IEEE TeC paper.
- Reorder instances by name first and noise level second.
- Remove number of samples from the name.

comment:27 Changed 22 months ago by mkommend
r17966: Changed Feynman problem instances to new normal distributed RNG.
comment:28 Changed 22 months ago by mkommend
r17967: Add GlobalSuppression file to HL.Problems.DataAnalysis.Instances to prevent persistence analyzer messages about missing StorableTypeAttributes.
comment:29 Changed 22 months ago by mkommend
r17969: Correct project file for HL.Problems.Instances.DataAnalysis.
comment:30 Changed 21 months ago by chaider

Check and adapt (if necessary) noise ratios of Feynman instances so that these are equivalent to the noise ratios of the Friedman problems.
If the different calculation has been introduced on purpose, we should define what we understand under noise ratio and how to calculate it.

r18032 noise generation method to ValueGenerator; use same method for generating noise in friedman and feynman instances
comment:34 Changed 19 months ago by chaider
- Status changed from assigned to accepted
comment:35 Changed 14 months ago by gkronber
Noise generation introduced in r18032 does not work for noise ratio = 1 (which means no signal left)
comment:36 Changed 14 months ago by gkronber
r18106: changed noise levels for Feynman instances.
r17635 branched trunk
