Bayesian Probability

The sigmatoid Bayesian, according to SEP, connects to a reverend called Thomas Bayes (circa 1700).

Bayesian Probability is like a reaction to the Mathematical Probability: what about our…

Basics of Bayesian Decision Theory

The use of formal statistical methods to analyse quantitative data in data science has increased considerably over the last few years. One such approach, Bayesian Decision Theory (BDT), also known as Bayesian Hypothesis Testing and Bayesian inference, is a fundamental statistical approach that quantifies…

Machine Learning Algorithms: Which One to Choose for Your Problem

When I was beginning my way in data science, I often faced the problem of choosing the most appropriate algorithm for my specific problem. If you’re like me, when you open some article about machine learning algorithms, you see dozens of detailed descriptions. The paradox is that they don’t ease the choice.

In this article, I will try to explain basic concepts and give some intuition of using different…

Price Optimisation Using Decision Tree (Regression Tree) - Machine Learning

INTRODUCTION TO THE RESEARCH QUESTION

The research was conducted to find out what price  maximises profit without sacrificing the high demand for the product due to the price being too high nor sacrificing the margins on the product due to the price being too low. 

The goal is to experiment with different price levels for the same product in one market place and country to see how sales volumes change with prices and which volume level of…

Finding and Using Data That Matters – 6 Things to Think About

Search any data related posting and you’ll soon be up to your eyeballs in reports on the promise of the new data era, techniques to help build a better data engine or incorporate new data widgets, and infographics and visualizations showing the kinds of insights you can get with the right mix of techniques.

Got it. Data is big. It’s expected to grow in volume to 35 to 45 zetabytes by 2020. As in seven sets of three zeros big.

It’s also transforming business processes big.…

Logistic Regression Vs Decision Trees Vs SVM: Part I

Classification is one of the major problems that we solve while working on standard business problems across industries. In this article we’ll be discussing the major three of the many techniques used for the same, Logistic Regression, Decision Trees and Support Vector Machines [SVM].

All of the above listed algorithms are used in classification [ SVM and Decision Trees are also used for regression, but we are not discussing that today!]. Time and again I have seen people asking which…

The Decision Frame

There are a number of movies that I consider much more suitable for television than theatre: Alien Versus Predator; Doom; Snakes on a Plane; The Cave; The Colony. The stories of these movies play out in environmentally-limited sometimes enclosed settings. In the theatre, I considered Alien Versus Predator the worst movie I ever had to sit through in my entire life, second perhaps only to the original Tron. But at home on a 36-inch display, it has become one of my all-time favourites. On the…

Bigdata Analytics and Supply chain management

     I am a newbie to Bigdata and would like to highlight some significant advantages if incorporated in a company's supply-chain management strategies, expecting the reader's views and suggestions.

     Because, in recent past I have developed a online supply-chain management systems in which sellers and customers are matched using an algorithm. It acted as a decision support system and I needed to dig deeper on the available data to get more insights over the data pattern (even for…

How Cross Pollination Helps Organizations to Ideate & Innovate?

One of the marvels that the age of data and technology presents is the ability to analyze and determine the minutest of details in the world today. Several of these innovative breakthroughs pass unnoticed under the gaze of daily life. Yet it is this dissemination of data and integration of innovation that is intrinsic the modern world. One field which has risen from the fore of the data deluge is ‘…

Seek the grail up the Knowledge Pyramid, not down

In following the big data 'buzz' and trends, it appears that there is a disconnect between our analytical goals (i.e., the types of questions our customers are trying to answer) and the computational substrate on which we build in order to answer them.

NoSQL technologies, while being far more…

First the data, then the decision, then the profit.

Working and valorising Big Data is business-as-usual for companies that have built their business model on it. For companies that don’t compete on analytics, that is for whom analytics is not a core element of their strategy, it’s a huge challenge.

But Big Data is the talk of town nowadays. I think that a part of the growing management interest is due to two factors:

  1. The relentness search for cost efficiency and growth in the current economic downturn;
  2. A…

Less data, more insight, better decisions

Big Data can help in mapping and understanding customer behaviors, and in developing one-to-one marketing programs or innovative services. However, Big Data is too often presented as a technological capability subsequently requiring armies of data scientists to mine and analyse data.

Yes, managing and exploiting the growing amount of internal and external data is a necessary condition to steer business performance. But it is far from a sufficient condition.

In a recent meeting…
