More on Fully Automated Machine Learning

Summary:  Recently we’ve been profiling Automated Machine Learning (AML) platforms, both of the professional variety, and particularly those proprietary one-click-to-model variety that are being pitched to untrained analysts and line-of-business managers.  Since our first article, readers have suggested some additional companies we should look at which are profiled here along with some interesting observations about who is buying and why.

Manipulating and processing data in R

Manipulating and processing data in R

Data structures provide the way to represent data in data analytics. We can manipulate data in R for analysis and visualization.

One of the most important aspects of computing with data in R is its ability to manipulate data and enable its subsequent analysis and visualization. Let us see few basic data structures in R:

a. Vectors in R

These are…

Improving life with IoT and Analytics

Last weekend I went to attend one event hosted by GE digital in association with T-HUB and Idea labs.

The event was about industrial IoT and Predix Platform developed by GE Digital for IIOT.

It was a very much informative event, and I also had the privilege to meet some awesome people over there who are part of this platform development.

GE is the well-known company we all know.   

Now coming to the usage of IoT and analytics in this. GE Develops a lot of turbines…

Creating functions in R

Functions are used to simplify a series of calculations.

For instance, let us suppose that there exists an array of numbers which we wish to add to another variable. Instead of carrying out separate calculations for each number in the array, it would be much easier to simply create a function that does this for us automatically.

A function in R generally works by:

(a) Defining the variables to include in the function and the calculation. e.g. to add two…

Sequenced Differential Lattices and Randomness

The images on this blog are from an algorithmic environment that I first developed about 15 years ago - rendered using a graphical system that I wrote in Java.  A “differential lattice” is a structured array of differences between two points:  e.g. the difference between the closing price of a stock on day T-0 (today) and T-6 (a week ago).  Consequently, if the closing prices are $10.10, $10.20, $10.30, $10.40, and $10.50 (today), then 0/3 is from T-0/T-3 or $10.50 less $10.20 = $0.30.  A…

Dogs vs. Cats: Image Classification with Deep Learning using TensorFlow in Python

The problem

Given a set of labeled images of  cats and dogs, a  machine learning model  is to be learnt and later it is to be used to classify a set of new images as cats or dogs. 

  • The original dataset contains a huge number of images, only a few sample images are chosen (1100 labeled images for cat/dog as training…

Building Convolutional Neural Networks with Tensorflow

In the past year I have also worked with Deep Learning techniques, and I would like to share with you how to make and train a Convolutional Neural Network from scratch, using tensorflow. Later on we can use this knowledge as a building block to make interesting Deep Learning applications.

The contents of this blog-post is as follows:

  1. Tensorflow basics:
    • 1.1 Constants and Variables
    • 1.2 Tensorflow Graphs and Sessions
    • 1.3 Placeholders and…

Nice Generalization of the K-NN Clustering Algorithm -- Also Useful for Data Reduction

I describe here an interesting and intuitive clustering algorithm (that can be used for data reduction as well) offering several advantages, over traditional classifiers:

  • More robust against outliers and erroneous data
  • Executing much faster
  • Generalizing well known algorithms

You don't need to know K-NN to understand this article -- but click here if you want to…

Invest More beyond Tools to Improve Reporting Performance

As a type of front-end data service intended for end-users, reports in applications have received a lot of concerns about their performances.  It’s all users’ wish that parameters in and query and aggregate results out in no time. Though less than twenty seconds’ waiting time is within a tolerant range, three to five minutes will threaten to extend beyond a user’s patience with the worst product experience.

But why is a report so slow? And how shall we optimize its…
