Hi all,
A component of my trading system uses a Coputational Network Toolkit model (https://www.cntk.ai/). To make a prediction requires sending it transformations of the current period's close, for each instrument in my universe.
I've thought of two ways I could consult my model, and I wanted to know whether either is possible, given QC's data restrictions.
1. Host the model (<1MB) and CNTK (290MB) within a QC VPS and communicate with CNTK via its C# wrapper. NB: CNTK doesn't require installation, but needs 64-bit Windows; and,
2. Use Azure (https://azure.microsoft.com/en-us/) to deploy the model via a website (there may be other ways to publish models).
This second option is my preference as I wouldn't need to update software, etc. Might it be possible to whitelist a custom Azure website? I'm pretty sure I can turn off data persistency in Azure, but I'm not sure (yet) how I could provide QC surety of this.
I appreciate that this should be possible using LEAN, but I'd like to leverage the QC Prime service.
Any thoughts appreciated; Thanks,
Gavin.
NB: I'm not looking to use QC compute resources to build models, I can do that on my local machine.

Hi @GavinMillynn! You can make a REST interface to your model and have the algorithm consult it for decisions? Would this suit? (The only limitation is that you couldn't use any QC data for the decision making). If your data period is daily you could use an external source like Yahoo to do your model updates.
The backend is Mono / linux based and we couldn't install it if it requires windows.

Thanks @Jared, I just needed to know the limits/parameters of the QC system, before I headed down wrong path.
Have a good one mate.

I am also interested in understanding if we can use CNTK (which is just a set of 64-bit DLLs) on the QC environment. This question was asked 2 years ago, hopefully there is a different answer than exposing an API. (BTW I tend to use F# so great to see that an F# environment is now available)

As it stands today, CNTK is not supported on Mac (but is supported on Linux) and I am not sure if it runs under Mono.
Another possibility is to use TensorflowSharp

Thank you Faisal Waris! We're making some progress and will soon merge in the recent library requests. Those interested can follow along on Github:
