FAQ

Launcher

What is the difference between New Project and Only Training?

Both create a local project. Only Training is a faster launcher path into the training workflow, but it still uses the normal 6-step structure (Steps 1–5).

What is the difference between Open Project and Only Prediction?

Open Project restores a full .dvp project at the step where it was last saved. Only Prediction starts a project shell with only Step 6 active and is meant for .dvm inference use cases.

Can I open a .dvp by double-clicking it?

Yes, if file associations are set up on your operating system. The desktop app also supports opening .dvp and .dvm files from the command line.

Files

Where are desktop projects stored?

On the local filesystem as .dvp files at the path you choose when creating the project.

Can I export a trained model separately?

Yes. After training in Step 4, export the active model as a .dvm file.

Do I need a .dvp project to use Only Prediction?

No. The desktop app creates a minimal project shell and then lets you load a .dvm.

Can I use a .dvm without a full project?

Yes. That is exactly what Only Prediction is for.

Application menu

What does Clear Invalid Data do?

It removes generated artifacts (trained models, predictions, analysis results) and resets steps 4–6 to their initial state. Use it when you want to start training fresh without re-importing data.

Where do I configure the backend URL?

Use Settings > Backend in the application menu. The configuration window includes a connection test.

Workflow

Should I use Fast or Robust validation?

• Fast for quick baselines and large datasets
• Robust for more reliable model selection and smaller datasets

When should I use the Optimizer?

Use it after a manual baseline when you want automated hyperparameter search. Start with a preset in basic mode, then switch to advanced mode when you need more control over the search space.

What does the execution preview show?

The execution preview box on the Model Design page summarizes the total training effort: how many runs per trial for tuning, how many additional runs for reporting, and the final model training. It updates live as you change settings.

What is the difference between Basic and Advanced optimizer mode?

Basic mode offers curated presets — select one and start. Advanced mode exposes full control over trials, timeout, sampler, pruner, direction, seed, optimize metric, and per-parameter search ranges.

Prediction

Can I predict without retraining?

Yes. Load a .dvm file and run Step 6 directly.

Can I enter values manually instead of uploading a CSV?

Yes. The prediction table supports manual input rows for quick scenario testing. Numeric columns show a text input and categorical columns show a dropdown with the known class options.

What do the red-highlighted cells in the prediction table mean?

They indicate values outside the range seen during training. These are extrapolation candidates and the prediction may be less reliable.
