In this article, I explain how to build a tool to detect faces in a picture. This article is a sort of how-to design and implements a tool by using a neural network. For the design part, I describe how to: build the business model thanks to a neural network; adapt the network to the specific domain of face detection by changing its knowledge; use the resulting domain with a go-based infrastructure; code a little application in Go to communicate with the outside world.
In the previous post, I made an introduction and a POC to interact with ONNX models and Go. I have decoded the information to reconstruct a graph. Now I propose to expand the principle and to create a proper execution backend based on Gorgonia. This post is a bit more technical than the previous one because all the concepts needed to work should be present in the last article.
This year has started with a lot of deep thoughts about the software 2.0. My conclusion (which is slightly different from Andrej Karpathy’s consideration) is that a software 2.0 is a combination of a Neural network model and its associated weights. This is a concept; now the question is: how to materialize the idea? What artifact represents a software 2.0. I emitted several ideas and tried one of them: to serialize the mathematical model and the weights.
