Here, I've used the famous Iris Flower dataset to show the clustering in Power BI using R. I've used the K-means clustering method to show the different species of Iris flower.
About the dataset: The Iris dataset has 5 attributes (Sepal length, Sepal width, Petal width, Petal length, Species). The 3 different species are named as Setosa,…Continue
Background: Business intelligence software casts a wide net. Software for site selection, customer segmentation, marketing tests, employee productivity, operational metrics, sentiment analysis, profitability sectors and mapping tools all fall in this category.
Businesses are constantly challenged with business intelligence software questions such as:
· Should we “Build or Buy”?
· Should we “Retain, Upgrade, or Replace”…Continue

It seems like it has been a long time since big data was all the hype in tech. Over the past year, it’s blockchain that has been grabbing headline after headline. It does appear fitting since blockchain is proving to be quite the disruptive force. This, however, doesn’t mean that data stakeholders can just tune out all this blockchain frenzy. Data is still the lifeblood of modern tech. Disruptive technologies and data will inevitably have an interplay.…Continue

Tuesday of Strata Data Conference is my favorite of the four days. The calm before the storm of the keynotes and short presentations of Wednesday-Thursday, Tuesday revolves on half day training sessions that afford reasonably deep dives into technical data science topics. This year my choices were Using R and Python for scalable data science, machine…Continue

Summary: A major problem with chatbots is that they can only provide information from what’s in their knowledge base. Here’s a new approach that makes your chatbot smarter with every question it can’t answer, making it a self-learning lifelong learner.
If you’ve been keeping up with the…Continue
The problem this blockchain project is trying to solve is allowing a number of people to create a knowledge product in a decentralized way, without a person dictating who should contribute and who should not. Whose contribution to the knowledge product will be accepted or rejected is done by a consensus of all participating members. The system should allow transparently assessing and scoring the contribution of each of the participant to the final product. The system should also allow…Continue

As everyone knows Machine learning studies computer algorithms for learning to do stuff. We might, for instance, be interested in learning to complete a task, or to make accurate predictions, or to behave intelligently. The learning that is being done is always based on some sort of observations or data, such as examples…direct experience, or instruction. So in general, machine learning is about learning to do better in the future based on…Continue

Knowledge is power
With IDC estimating that the data mountain has now reached five zettabytes, it is not a case of a business not having enough data to make business decisions, but arguably knowing too much. For many, it is the old adage of not being able to see the wood from the trees. Armed with all this information, businesses should be able to operate more efficiently and accurately than ever before, but many simply don’t have the key to unlock valuable…Continue

"No one wants to be sold but everyone wants to buy."
Most of us hate being sold. The moment we know someone is selling something, we keep our guards up.
In the book, The Challenger Sale, authors Mathew Dixon and Brent Adamson surveyed over 6000 salespeople from around the world and found that ‘challenger salespeople’ outperformed every other group. Who are these challenger salespeople? These…Continue

Ask for feedback from just about any critic of the R statistical package and you'll hear two consistent responses: 1) R is a difficult language to learn, and 2) R's data size limitation to physical RAM consigns it to toy academic applications. Having worked with R for over 15 years, I probably shared those views to some extent early on, but no longer.
Yes, R's a language where array-oriented processing and functional…Continue
