ml.dtw: Unable to Map Input #133

Closed jcurtis-cc closed 6 years ago

jcurtis-cc commented 7 years ago

Attempting to follow the helpfile, receiving "error ml.dtw: unable to map input"

Training phase needs much better clarification in the helpfile:

Procedurally, where exactly should the line objects be triggered? How does the 'Test' subpatch relate to the main patch? When are these operations intended to be triggered to train correctly?

Also: send objects are labeled [s mlp] instead of [s dtw]

jcurtis-cc commented 7 years ago

Unable to Map input occurs when recording is off (contrary to help file)

@jamiebullock Can you please elaborate whether recording should be on during mapping: bug or feature?

Test one and two both map to 1. Correct? Seems odd

Finally, how do you suggest training multiple examples for gesture recognition within ml.dtw?

If you can provide me clear examples on how to get this running correctly I'd be glad to create a clear helpfile for you!

Hi @JCurtisRMIT, sorry for the slow reply!

This issue is now duplicated by a more recent issue (#145)

The helpful is basically misleading. Record needs to be toggled on / off for each training example. Additionally, it should be used for segmentation during map. So the typical sequence is:

record 1 add <class 1> ... record 0 record 1 add <class 2> ... record 0

etc

train

record 1 map <observations 1> record 0 record 1 map <observations 2> record 0

etc

I explain this in more detail in #145. In an upcoming release the helpfile will be improved. Does this answer the question?
