Welcome to another installment of deep learning in Ruby. Today, we’ll look at FER+, a deep convolutional neural network for emotion recognition developed at Microsoft. The project is open source, and there’s a pretrained model in the ONNX Model Zoo that we can get running quickly in Ruby. First, download the model and this photo of a park ranger. Photo from Yellowstone National Park We’ll use MiniMagick to prepare the image and the ONNX Runtime gem to run the model. gem "mini_magick" ge...
