|I want to take a minute to highlight one of the apps of Deep Learning Toolbox: Deep Network Designer. This app can be useful for more than just building a network from scratch, plus in 19a the app generates MATLAB code to programatically create networks! I want to walk through a few common uses for this app (and perhaps some not-so-common uses as well!)|
net = googlenet; net.LayersSeries? DAG? How about when I show you this portion of the network in the app? You can quickly see this is definitely not a series network. (It's DAG!) The app lets you quickly visualize what the network looks like, and see which connections are made. This can be helpful for a deeper understanding of the network, or simply getting a high level overview of the structure. 4. What went wrong? Though not technically the Deep Network Designer*, there is a button that launches the deep network analyzer. Occasionally, I will get a question such as, "Why is my network erroring out?" and I always start the investigation with the analyzer. This will check for problems before you start training which eliminates the not-so-attractive red error message in the command window. *you can also get to the Network Analyzer programatically:
analyzeNetwork(net);5. Learning more about deep learning This is not an official benefit of the app, but something I'll mention because it's helped me. Before I started using the app, I wouldn't have been able to tell you anything about "Leaky ReLU layers", since I didn't know they existed! By taking a look at all the different layers on the left**, I can pinpoint new layers I may want to learn about, then go to the documentation to learn more! For example, A leaky ReLU layer will take any input value less than zero and multiply it by a fixed scalar. In comparison, a regular ReLU will set anything less than zero to zero. **If you are looking for every layer that exists in MATLAB, here is a link to all layers in documentation. Hopefully you feel compelled to try the app right now. As always, you can get a free trial of all our deep learning tools to try the latest functionality: Link to Trial Do you like this app, or like another app better? Let me know in the comments below.
