This project is currently just a proposal.

About you

IRC: lpillsbury
Github: lpillsbury
School: Pasadena City College and Boston University before that
Country: United States
Primary language : English

Typical work hours : 9AM-5:30PM US Pacific, though I may be on Eastern time part of the summer
Previous GSoC participation: I haven't ever participated in GSOC; I am interested to do so to learn more about embedded software, improve my coding skills, and participate in the community. I use open source tools all the time, and it is really exciting to make something useful that other people would use too.

About your project

Project name: TensorFlow Lite Compatability with BeagleBone AI


While the specs of BeagleBone AI are awesome, it seems limiting for an AI board for the general public to not be able to access TensorFlow Lite. I would like to change that by choosing a current release of TensorFlow, and writing the code necessary to run it on the Arm M4 processors that the BeagleBone AI board has, and that should work with TensorFlow Lite. This project will be a combination of C coding, dealing with the Linux kernel, and doing some example cases with TensorFlow Lite in python. Obviously, given the diversion between OpenCL and TensorFlow, there is no perfect way to seamlessly integrate TensorFlow Lite, but there seem to be enough people in the community who want it, that it is worth at least making a gesture towards a compatibility solution. I first realized this was a problem when I decided I wanted to learn more about AI on the edge. One of the first things that comes up when I search for information on this topic is using TensorFlow Lite and the wide variety of other boards that it plays well with.

Ideally, I'd spend the first few weeks getting TensorFlow Lite working on a BBAI, document my hacking process, and then create a smooth stable way to make it work more out of the box. Then I'd spend the rest of the time doing examples that would be highlighted both on the BeagleBoard website, and also on the TensorFlow Lite Examples page by making a pull request to the owners of the github repo. Given that there are already examples of using TensorFlow Lite on Raspberry Pi, with picamera, the starting point would be to have equivalent BeagleBone examples, most likely doing image capture through OpenCV (OpenCV with BeagleBone Black). I'm also very interested in sound recognition, and if time allows I'd also like to do some examples in this area.


Provide a development timeline with a milestone each of the 11 weeks and any pre-work. (A realistic timeline is critical to our selection process.)

Experience and approach

In 5-15 sentences, convince us you will be able to successfully complete your project in the timeline you have described.


What will you do if you get stuck on your project and your mentor isn’t around?


BeagleBoard options are strong contenders with Raspberry Pi and Arduino as tools that are easy to use to do IoT and industrial projects. While BeagleBones are geared more towards engineers and have some special features that actually make them quite different than the others (PRUs, ability to do low level and high level control simultaneously, power usage etc), they often get compared with the other frameworks. Given that Raspberry Pi and Arduino have TensorFlow Lite compatibility, I think it is important for BeagleBones to do the same. Also, there are algorithms that are easier to access with TensorFlow Lite than in other settings.
