Alright; so this whole input pipeline thing in pretty much every framework is the most undocumented thing in the universe. So this article is about demystifying it. We can break down the process into a few key steps:
Acquire & Label Data
Process Label Files for Record Conversions
Process Label Files for Training a Specific Network Interface
Train the Specific Network Interface
This is part 1. We will focus on the 3rd item in this list; processing the files into TF Records. Note you can find more associated code in the TensorFlow section of this git repository: https://github.com/drcrook1/CIFAR10
So you likely will run into this at some point. You are reading data from somewhere and it is relative path based; but that doesn’t necessarily always help load data in especially if you are storing data and your code in separate paths (which is common) or if you are sharing data with a team; or even if your data is just somewhere totally different.
Anyways; this article will help convert a .csv label file with actual named labels to a label file with full path with a numerical label that can be more easily one hot encoded during the reading process. Note for deep learning often this is a two step process. Step 1: Convert from relative pathing to specific pathing & numerical labels. Step 2: Convert to framework specific storage format for input reading pipeline (which varies framework to framework). Here we cover Step 1. We will be using the CIFAR 10 data set which can be downloaded from here: https://www.kaggle.com/c/cifar-10/data
I’m not sure the title really nailed it well enough, but we are going to talk about solving VERY big problems as fast as we possibly can using highly sophisticated techniques. This blog article is really a high level overview of what you want to set up as opposed necessarily to the usual how to set it up. There are a ton of steps to the actual how to; I thought it best to just provide an overview in this article to what you want to do instead of how to do it.
If you are not familiar with Microsoft CoCos, you should be. Its a treasure trove of data for your learning pleasure! There just happens to be one pesky problem with it, and that is the fact that when attempting to find the files for training/testing; the Annotation file that ships with MS CoCo does not include the actual file name, but rather the image id. This sounds fine, except the data when you download it has a bunch of trailing stuff! In this article we will go through how to get it ready.
In this article I’m going to go through how to set up CNTK with Visual Studio Code and take advantage of those PASCAL GPUs I know everybody has these days. I will also do a breif overview of what CNTK and Visual Studio Code are and why they are so incredible for machine learning scientists.
So today I have decided to actually begin a write up on where I’m headed. Its taken a long while to come up with what my next adventure after food trucks was going to be, especially with all of the things you can do with embedded technologies and machine learning. So here it is, a self driving race car.
In this article I aim to lay out the high level plan of attack for what my team and I are building and some of the direction on where we are headed.
