Learner Reviews & Feedback for Classify Radio Signals with PyTorch by Coursera Project Network

About the Course

In this 2-hour long guided-project course, you will load a pretrained state of the art model CNN and you will train in PyTorch to classify radio signals with input as spectogram images. The data that you will use, consists of spectogram images (spectogram is a representation of audio signals) and there are targets such as ( Squiggle, Noises, Narrowband, etc). Furthermore, you will apply spectogram augmentation for classification task to augment spectogram images. Moreover, you are going to create train and evaluator function which will be helpful to write training loop. Lastly, you will use best trained model to classify radio signals given any 2D Spectogram of radio signal input images....

It was a wonderful project which not only covers a few concepts of signal processing but also sheds light on transfer learning with Pytorch.

I feel the instructor put in very little effort. Usually in other courses the instructor provides an Completed Copy of the entire code .

There was an entire section of code and video which the instructor seems to have missed altogether.

The instructor seems to just copy the spec_augment library from some GitHub repository without showing which package to install. Overall I would say this was very poorly executed.

Very little discussion was spent into why spec-augment was used at all? Even a signle statement saying that the masking improves the Robustness of the Acoustic model (without the LM) on datasets such as Librispeech without any noise aware training shows good results would have sufficed.
