We do data science.

Prior to Applying "Out-of-Bag" on the Recently Arrived Jetson TX1
Silverpond has been waiting for a Jetson TX1 Dev-Kit to arrive for the last couple of weeks in order to test out some new deep-learning models that we’ve been developing on a lower-power, smaller-form-factor board. Well here it is on my desk! What’s exciting about this computation format for us is that it allows the fairly computationally intensive tasks involved in deep-learning inference (and some backpropagation too) to be taken back out of the cloud and moved closer to the point of data-ingestion.
The marketing spiel goes like so:
The Jetson TX1 Developer Kit is a full-featured development platform for visual computing designed to get you up and running fast … This makes it ideal for all your applications requiring high computational performance in a low-power envelope.
Part of what makes deep-learning (and machine-learning in general) interesting, is that the refinement and development of the model can be decoupled from the use of the model for inference. In practice this means that once a neural-network has been trained, it can be used effectively for inference with much lower resource requirements than during training. Of course, this doesn’t mean that you’ll be able to do image classification with your Casio calculator, but you can certainly take advantage of lower power-factor computers to perform inference in the field.
This was the use-case that inspired us when we considered using the Jetson hardware. We’ve traditionally deployed a lot of our services to cloud infrastructure, but that won’t work in off-line environments. The kinds of use-cases that the Jetson facilitates are often especially interesting too, as one of the appeals of AI is that it can drive autonomy, and autonomy implies (though doesn’t necessitate) independence from the hive - remote services in this case.
The first model that we’re planning to run on our Jetson is still top-secret, however it is an extension of the pedestrian-detection demo that we’ve had online on our site for some time. We’ll be sure to tell you all about it as soon as possible. Stay tuned!
