CHANGES
Support a new sampler based on Sobol's Quasi-random Sequence
Goptuna now supports Sobol based sampler. See the paper S. Joe and F. Y. Kuo, Remark on Algorithm 659: Implementing Sobol's quasirandom sequence generator, ACM Trans. Math. Softw. 29, 49-57 (2003). for details.
np.random.rand() (seed=0) |
Sobol (Goptuna) |
|---|---|
 |
 |
Usage is like this:
import (
"github.com/c-bata/goptuna"
"github.com/c-bata/goptuna/sobol"
)
func main() {
study, err := goptuna.CreateStudy(
"goptuna-example",
goptuna.StudyOptionRelativeSampler(sobol.NewSampler()), // Set Sobol based sampler.
)
...
}Add github.com/c-bata/gorm/rdb.v2
Add rdb.v2 package built on gorm v2.
So github.com/c-bata/goptuna/rdb package is now deprecated.
- Use gorm v2 package (#124).
- Fix duplicate trial numbers are assigned on parallel execution (#130).
- Add CASCADE ON DELETE constraints (#170).
- Drop schema compatibility with Optuna (#166).
Dashboard
- Add datetime_start column on top page of Dashboard (#169).
- Put select box to change the reload interval time on AppBar (#176).
Minor compatibility changes
- Include the upper bound of uniform/loguniform distributions (#205)
v0.7.1
New features
Dashboard: filtering trials by state
You can now walk through trials by filtering and sorting.
Dashboard: Add button to delete a study
You can delete a study from dashboard.
v0.7.0
New feature
Built-in Web Dashboard (#157)
You can download standalone binaries (JavaScript files are also embedded in these binaries) via GitHub release, then you can open Web dashboard like following command.
$ goptuna --version
goptuna version 0.7.0 (rev: e8db5dc)
$ goptuna dashboard --storage sqlite:///example.db --host 127.0.0.1 --port 8000Goptuna's RDB storage backend is compatible with Optuna. So this CLI is able to visualize Optuna's optimization results.
Improvements
- Faster TPE categorical sampling (#152)
Bug fixes
ʕ◔ϖ◔ʔ v0.6.0
New feature
- Support IPOP-CMA-ES and BI-POP-CMA-ES algorithm (#131, #135, #136, #141)
- Please check the benchmark results on two-dimensional Rastrigin function at #141.
- Auger, A., Hansen, N.: A restart CMA evolution strategy with increasing population size. In: Proceedings of the 2005 IEEE Congress on Evolutionary Computation (CEC’2005), pp. 1769–1776 (2005a)
- Hansen N. Benchmarking a BI-Population CMA-ES on the BBOB-2009 Function Testbed. In the workshop Proceedings of the Genetic and Evolutionary Computation Conference, GECCO, pages 2389–2395. ACM, 2009.
- Add BlackHoleStorage towards 100k+ evaluations (#105)
- Add TPE sampler options (#127)
API changes
Pruning (Early-stopping) APIs are changed without backward compatibility.
While I added an example which uses successive halving pruner at #120, I found a lot of issues. I'm sure that nobody uses pruning functionalities (I also confirmed that Kubeflow/Katib and sile/kurobako-go does not use pruning functionalities). So I fixes those issues. And I merge it without backward compatibility.
- Fix typo of
OptionSetReductionFactor - Alter the argument of
trial.ShouldPrune()and removetrial.Report().
Some APIs are renamed without breaking changes.
These changes are added with backward compatibilities. Older functions are deprecated.
- Rename RandomSearchSampler to RandomSampler (#137).
- Rename StudyOptionSetDirection to StudyOptionDirection (#138).
- Rename StudyOptionSetTrialNotifyChannel to StudyOptionTrialNotifyChannel (#138).
Minor bug fixes
- Fix
IntUniformDistribution.ToExternalRepr()(#102) - Fix
IntUniformDistributions.Contains()(#103) - Fix a bug when set attrs multiple times (#121)
- CMA-ES: fix numerical overflow errors (#126)
- Fix a bug of successive halving pruner (#120)
Example
ʕ◔ϖ◔ʔ v0.5.1
ʕ◔ϖ◔ʔ v0.5.0
From this release, new suggest API SuggestStepInt for step-interval integer parameter is available.
SuggestUniform, SuggestLogUniform and SuggestDiscreteUniform are deprecated. These APIs are renamed to Suggest...Float API.
New feature
- Suggest int parameter with step (#98)
API changes
- Rename SuggestUniform to SuggestFloat (#96)
