Let’s begin by understanding a Matrix. Well, a Matrix is an array of numbers, in a combination of rows and columns. The size of a matrix is defined by the number of rows and columns that it contains. A matrix with an m rows and n columns is called an m x n matrix or m-by-n matrix, while m and n are called its dimensions, denoted by [a_ij]
Though we have all heard of Data Analytics, many of us are a bit unclear as to how it can really help transform businesses. Well this recent article in EnterpriseAppsToday shares four clear examples that will help us understand the ‘funda’.
Way back in 1830, Joseph Jagger, an engineer with an analytical mind, began researching the mechanisms of roulette wheels, one of his passions. He suspected that the results of each roulette spin might not be the result of purely random sequences. He wondered, “Is there a system, do the balls have a pattern, were some numbers likely to come up more than others?”
What did he do next? Watch this video and find out
I recently read an article in Diginomica, where Geoffrey Taylor, academic program manager at business analytics firm SAS was quoted as saying “Those precious few with the knowledge and experience to drive analytics without crashing – the data scientists – are as rare as “unicorns”. It’s true…It’s not technology that is holding back organizations trying to get the most out of Big Data analytics, but a lack of talent. Almost every big organization today has got on the Big Data wagon and is spending big money on Big Data projects. This means that all these companies are looking for Big Data specialists. They are willing to pay them high salaries but the problem is that there just aren’t enough unicorns to fill these positions.
Sentiments expressed in online news, comments, reviews, etc plays a vital role in today’s business. The public is increasingly more likely to buy the product of a business, when it has positive reviews on e-commerce and social media websites. For instance, people tend to buy a book which has 4 and up star rating on sites such as Flipkart and Amazon.
However awareness is spreading about bought and paid reviews on the web and today many customers have started to think, “Is this review a fake one?” Yes, its hard to believe but true! Services such as buyazonreviews.com and buyamazonreviews.com will give you a good review; for a price ofcourse.
Sohini Bagchi in her article in CXO yesterday, talks about what is fueling the booming e-commerce sector in India today. She says that the ‘Hyper growth of mobile customers’ is definitely one of the main reasons. She goes on to quote Gaurav Vohra, CEO Jigsaw Academy as saying, “As more people are logging on to e-commerce portals, companies are hiring aggressively and are also offering lucrative salaries to attract the right technology talents, in the areas of cloud, analytics and data mining,”
Fun Fact- Do you know that the first published picture of a regression line illustrating this effect, was from a lecture presented by Sir Francis Galton in 1877. In fact it is said that it is he, who first coined the term linear regression. Galton was a pioneer in the application of statistical methods to measurements in many branches of science. He spent years studying data on relative sizes of parents and their offspring in various species of plants and animals. One of his most famous observations was that: a larger-than-average parent tends to produce a larger-than-average child, but the child is likely to be less large than the parent in terms of its relative position within its own generation.
Well today Linear Regression Models are widely used by Data Scientists everywhere for varied observations. In this blog post I am going to let you into a few quick tips that you can use to improve your linear regression models.
Fit many models
Firstly build simple models. Using many independent variables need not necessarily mean that your model is good. Next step is to try and build many regression models with different combination of variables. Then you can take an ensemble of all these models. This might help you arrive at a good model.

A lot of working women take a 1 to 5 year mid-career break in order to look after their children when they are very young. Once the kids grow up, many women want to resume their careers, but very often hit a wall – their skills (especially if in the technical field) are considered obsolete, or they may not have experience with the latest tools or practices prevalent in their industries.

This past week all our thoughts and prayers have been with the people of Nepal. Though rescue efforts continue day and night, the death toll is rising, and many remote areas are still not accessible. With India and other neighboring countries, countless NGO’s and foreign governments, as well as the UN on the ground, doing their best in a race against time, we can only hope that may more are saved and that the herculean task of rebuilding their lives can begin.
Through it all, it has been heartening to see that Data has and will continue to play a crucial role in the whole rescue effort. We came upon a fascinating article in Wired, that talks about how to date, 2,182 digital volunteers have been trawling 14,700 km2 worth of high resolution satellite imagery to identify 3,128 damaged buildings. Using data and satellite maps they helped the first responders’ even before they hit the ground.
In the past 2 years, the share of search through Mobile has gone up and so have the Social Media advertising revenues.
