Design Thinking:  Is it a Floor Wax or a Dessert Topping?

Do you old schoolers remember the Shimmer Floor Waxcommercial from the early (and best) days of the TV show “Saturday Night Live”?  In case folks don’t remember (because we are old) or never saw it (because you’re too uncool), the Shimmer Floor Wax commercial asked the question: “Is Shimmer a floor wax or a dessert topping?”…

Testing traditional Software vs. ML application - how to explain it to a non technical common man

With the increasing popularity of Machine learning today, it is important to focus the testing aspect of ML application. Testing of any ML application will not be same as testing traditional software. It has become a debatable topic. Many literature categorised ML application as non-testable. However, many are now trying to make it testable and coming up many innovative approaches. All are very much technical and normal users without technical knowledge find difficulties. Therefore,…

A Comprehensive Guide to Data Science With Python

A Hearty Welcome to You!

I am so thrilled to welcome you to the absolutely awesome world of data science. It is an interesting subject, sometimes difficult, sometimes a struggle but always hugely rewarding at the end of your work. While data science is not as tough as, say, quantum mechanics, it is not high-school algebra either.

It requires knowledge of Statistics, some Mathematics (Linear Algebra,…

Running Peta-Scale Spark Jobs on Object Storage Using S3 Select

When one looks at the amazing roster of talks for most data science conferences what you don’t see is a lot of discussion on how to leverage object storage. On some level you would expect to — ultimately if you want to run your Spark or Presto job on peta-scale data sets and have it be available to your applications in the public or private cloud — this would be the logical storage architecture.

While logical, there has been a catch, at least historically, and that is object storage…

New Square Method

Abstract

The “new square method” is an improved approach based on the “least square method”. It calculates not only the constants and coefficients but also the variables’ power values in a model in the course of data regression calculations, thus bringing about a simpler and more accurate calculation for non-linear data regression processes.

Preface

In non-linear data regression calculations, the “least square…

Recognizing Animals in Photos: Building an AI model for Object Recognition

Our model for recognizing specific animals in images is a neural network consisting of multiple layers, and the initial layers are already good at understanding the world in general. So instead of “re-inventing the wheel,” we only need to train the final layers.

I was excited to work on a recent project with one of our partners, Wild Detect, because it aligns with one of our goals at Appsilon — to use data science consulting to aid in the…
