Operationalizing SKLearn with Azure Machine Learning

web_servic-ified

Hello World!

So I just completed an incredible project with Brain Thermal Tunnel Genix, where I learned so much about pattern recognition, machine learning and taking research and algorithms and pushing those into a production environment where it can be integrated into a real product.  Today’s article takes those lessons and provides a sample on how to perform complex modelling and operationalize it in the cloud.  The accompanying Gallery Example can be found here.

Arduino + Reinforcement Learning = Autonomous Robot

Herby_V1

Hello World,

So there are a ton of articles out there on the theory of Reinforcement Learning, but very few with an actual application.  I watched a few lectures from Berkley, and read a few articles by NVidia and thought, “Well, lets just give this a shot”.  8 hours later, this is what I had.

Herby V1 simply learns to go forward as much as possible while avoiding obstacles.

Functional Coding in Python – The right way

Hello World!

So I’ve been on a bender with this Python thing not having proper functional piping.  I just can’t beleive it was not built in.  Every language should have this.  It cleans up your code so much its unbeleive-able.  Fear not however, I have built one for Python :D.  Now I just need to figure out how to create pip packages.  Anyways, lets just do a quick walk through on what it is, how it works etc.

The Cognitive Revolution

Hello World!

So here is a pretty raw blog article; not unlike most of my articles.  The cognitive revolution.  I’m going to coin this term today.  What the heck is this thing?  What does it mean for you?  What does it mean for me?  Where did it come from?  What is it?  These are questions I aim to answer in this blog article.

Docker, Tensor Flow and Scientific Computing

Hello World,

So this blog post is to get you operational with Docker, image and volume management with a pivot towards scientific computing and tensor flow.  So I am working on building a Jupyter Notebook for the local mahcine learning meetup to learn the ins and outs of Tensor Flow and deploy this thing up to Azure.  Part of getting this to work is not only managing the Docker Containers, but also the data on the volumes so when we deploy up to Azure and somebody opens up the notebook it comes pre-loaded with all the necessary tutorial data.

Decoding Woes Solved – Python

Hello World,

This is a short post.  Basically I had a data set come in, where there were some funky characters involved.  I was getting “Can’t read this; doesn’t appear to be UTF-8”.  Looked around on stackoverflow for a while to little avail.  I came up with this, which works.

dataPath = "C:\\data\\CompanyA\\DavidCrook\\davidData_Session1.csv"
fil = open(dataPath)
txt = fil.readlines()
txt = ''.join(txt)
works = pd.read_csv(StringIO(txt), index_col = 0)
doesntWork = pd.read_csv(dataPath, index_col = 0)

Just read the sucker with the standard file open and line reader, push it into a StringIO and then read into a data frame.  Guess what I’m doing from now on.

Standardize Continuous Data Shape for Neural Networks

Hello World,

So this is an interesting problem.  You are collecting data from somewhere and you want to feed it into a neural network for classification.  There is one main problem with this.  The shape of the data!  Neural networks and really just anything require specifically shaped data, you can’t just like give it something of ambiguous size.  There are tons of papers out there on dimensionality reduction, but nothing on dimensionality reduction to a specified size.  This article explains my approach.

Time Series Discovery with Python

Hello World,

This article is loosely based on a time series challenge from customer data.  I have fabricated 3 data files such that they represent the same challenge and we will go through the process of discovering that data.  The primary challenge in this data set is that it is from a sleep study and the researchers left the date portion of the time stamp off.  What this means is that at midnight, the data plots at the beginning of the x-axis.  The second challenge is lining up data to see if there is anything interesting with the time.  So yes, you can simply plot using the index that python generates, however I’m also interested in the actual time itself as this is a study involving humans.

Data Science 101 – St. Pete .Net Talk

Hello World,

Here is the link to the slide deck.

Here is the description as it exists on meetup and here is the link to the meetup page.

This session is an introduction to data science and how it fits into the greater application development workflow. We will begin with an generic architecture overview followed by an actual implementation example using several Azure components. We will then make a dive into data insights and algorithm development.

Becoming a Functional Data Scientist

Hello World,

So today, I was asked to put some thought into what we should focus our entry level data scientists on in terms of tech skills.  After I put a bunch of thought into it, I ended up coming up with this.  I decided that the most important aspect of this was a few items fold

  1. Don’t overload them
  2. Can deliver to production where the target can be anything, including IoT.
  3. They will not be concerned with building front ends.

I have to say, the result greatly surprised me.
