In one instance, one participant noticed the memory of the browser was reaching 3GB, and found this unusual, and also observed the consequences in training time.
Recommendation: Participants would benefit from API methods (namely in the training data class) that provide metrics about quantity or volume of data. This should help developers in design by making them explicit through the visual interface metaphors they develop. It should also be explained in the documentation the consequences of dealing with large data sets (e.g., training time, impact on the classification results outcomes, etc.)https://gitlab.doc.gold.ac.uk/rapid-mix/RAPID-MIX_API/-/issues/53Put homepage video behind a button2017-12-18T14:42:23ZMichael ZbyszyńskiPut homepage video behind a buttonIt is a little invasive to be hit by the "allow camera" dialog right on the front page of rapidmixapi.com.

In other words, this function gets input data frame-by-frame and buffers it into the right size series and calls dtw.run() every n number of frames.
Since this is going to co-exist with similar functions in Rapid-Mix API, we should come up with some general design for this kind of use.
@francisco This is basically what is happening when GVF is in following mode. AFAIK, GVF only does following -- there is no discreet mode for processing a pre-recorded input series.
@Joseph I think that hhmm.filter() is the same type of function as GVF.update() for continuous recognition?
This suggests to me that RapidLib/DTW should handle its own windowing.
I did consider a design that was some kind of windowedML object. That might take a pointer to a specific model and some window parameters. So something like:
```
temporalClassification myModel;
windowedMLObject myWindowThing(*myModel, <window size>, <hopsize>);
myWindowThing.continuousProcessMethod(<new data frame>);
```
That would need better names.
Is there any value in having this kind of object in the RAPID-MIX API?

Recommendation:
* Users will benefit from examples become building blocks that they can readily integrate in their code (scaffolding for capturing data, either to local storage or to a service)
* Some of the external libraries like the MYO have hidden global values it makes it difficult to use. The building blocks (i.e., sensor bridges) should have the exposed methods and state carefully designed, just as the API.
