Hi, thanks for these super-interesting thoughts.
Visualizations are key, and a hot topic here. Integrating with tensorboard is a neat idea and we'll definitely look into that.
We have a growing number of internal tools for doing the kinds of things you describe here that were using daily for customer projects. Coalescing them into something cogent and useful we can share as open-source is a stated goal of ours.
I appreciate you starting this conversation off, I'll be interested to see if others chime in; I bet we can end up with something pretty awesome.
I personally like the idea of decoupling things with clearly defined interfaces so that alternative visualisation approaches can be plugged in, especially if they have complex dependencies or environment setup requirements.
One general way to think about things would be to see training as a reduction process, such that:
@harold Would the code in the experiment folder be a good starting point to instrument a training cycle and stream out important metrics?
I didn't see (or find) a listener function (like test-fn) in the cortex/src itself. Is it likely to get added there?
Thanks!

I think so. The basic idea of experiment
is layer advanced functionality over, and capture best practices uses of, the core cortex api. train.clj
in experiment
does this for neural nets in general. The file you linked is specific to neural nets for classification (one specific type of problem they can be used to solve).

My guess would be no. The core functionality of training and running will be kept minimal in order to support various scenarios and remain minimal/composable/flexible.
@shark8me: Do you feel that your two recent tensorboard pull requests address this issue?
Yes, it fixes the issue, this can be marked as resolved.

Hi all,
Other neural network implementations have tools that aid visualization and debugging of a network while being trained. Specifically, I've found that the Tensorboard UI (from Tensorflow ) is quite capable.
The toolkit should be capable of turning on (or off) instrumentation for different parameters, such as
To enable the same kind of functionality in Cortex, there are a few design choices:
To me, the second approach is preferred for two reasons:
I would like to hear your thoughts on this topic
Thanks!
