AlexNet visualization


I’ve been diving into deep learning methods during the course of my PhD, which focuses on analyzing audio and video data to uncover patterns relevant to the dolphin communication. I obtained a NVIDIA Titan Z through an academic hardware grant and installed Caffe to run jobs on the GPU using Python.

As a first step, I have been utilizing Caffe’s implementation of AlexNet (original paper) to tackle dolphin detection in video using R-CNN (by Ross B. Girshick) and classifying whale calls in audio (work presented at DCLDE 2015).


For the conference presentation and eventually for my dissertation defense, I wanted to make use of a visualization of AlexNet. I was unable to find a satisfying visualization other than the original:

AlexNet from ImageNet 2012 (Implemented on 2 GPUs)

Another visualization of AlexNet is the graphical view (below), which also provides the difference between the original AlexNet and Caffe’s implementation (CaffeNet):

What I was really looking for was a visualization of AlexNet similar to the ones that exist for LeNet:

Here is my current visualization of AlexNet + SVM, a configuration I have been using for my specific classification tasks. I hope this can be useful for other researchers (give me a shout out someday) and I hope to update the image if anyone has helpful comments. Enjoy!

If you use this image in an academic context, please cite it. Thanks!
