This applies to many tech job interviews. But here we provide specific advice for data scientists and other professionals with a similar background. More advice is being added regularly.
Here's the list:
So far in 2016, we’ve heard a lot about Big Data, the Internet of Things, and the hottest new marketing technique on the block: ‘hyper-personalised’ marketing. Marketers are increasingly interested in focusing their efforts on individuals, not database segments, because that all-important personal attention is shown to increase engagement, inspire customer loyalty and…

Internet of Things (IoT) is a network that is embedded with sensors, electronics, network connectivity, and software enabling physical objects to gather and exchange data. As IoT rises into dominance, sensors are playing a pivotal role for measuring the physical quality of objects and enumerating it into a value, which can be read by another device or user. IoT devices are equipped with sensors which are capable of registering changes in pressure, temperature,…Continue

You have gathered gigabytes or terabytes of unstructured text, for instance scraping the Internet, or pieces of email from your employees or users, or tweets, or millions of products that you want to categorize (only product description and product name is available - sometimes with typos). Now you want to make sense of it, and extract value, possibly design a nice search engine so that your customers can easily find your products. The core algorithm that you need is an automated cataloguer,…Continue
And creates the first legit, private lottery company. The winning numbers, to be published each week, are just as random and unpredictable (if not more) than winning numbers from state lotteries. It can be designed so that the expected gains for participants are far more favorable and more closely aligned with what casinos offer: in short, the odds of winning and multiplying your (say) $20 bet by (say) 10 or 100, can easily be made much higher than in traditional lotteries. It even beats the…Continue
If you are a start-up director in 2016, not a week goes by without someone talking to you about unicorns.
It is difficult to imagine the feeling of riding a unicorn. Do you feel the wind of success rush against its skin? Do you fear the arrows and traps of pitiless hunters? Do you feel a special sense of excitement when you get to the end of the rainbow of profits?
I find it easier to imagine the state of mind of the directors of Cloudera, Hortonworks or MapR, who are now the…Continue

It is not a huge stretch to say that almost any industrial activity or even a private activity in the entire world is impossible without oil and gas. These resources are not only used in heat and power space but also in everyday items like Manufacturing, Apparel and Transportation. Oil & Gas is acting as a lubricant to smoothen the operation in several industries. However, Oil & Gas industry in itself has undergone most difficult phases in past compared to other industries. The…Continue

Let me clarify something before my friends who work for cross channel attribution companies try to kill me. I don’t think that the market for cross-channel attribution is inherently dead, but I do believe that the way most vendors offer those services today is dead.
I believe that the markets for marketing mix modeling and cross channel attribution are going to merge…Continue
Every January, mighty crowds of electronics and IT professionals descend on Las-Vegas, Nevada to attend the annual Consumer Electronics Show.

The education system used to have two streams. Bright students went to schools of higher learning – universities and colleges, where, among other things, they learned how to design stuff. So-so students were filtered into professional schools, where they became plumbers, carpenters, and factory machinists. In other words, these “average” students became the makers of things. This dual educational stream – creators and makers – has served the society well.…Continue

It’s all well and good to ask if androids dream of electric sheep, but science fact has evolved to a point where it’s beginning to coincide with science fiction. No, we don’t have autonomous androids struggling with existential crises — yet — but we are getting ever closer to what people tend to call “artificial intelligence.”
Machine Learning is a sub-set of…Continue

Summary: Artificial General Intelligence (AGI) is the long sought after ‘brain’ that brings together all the branches of AI into a general purpose platform that can perform with human level intelligence in a broad variety of tasks. Will it free us or replace us? It’s closer than you think.Continue
Andrej Karpathy’s post “The Unreasonable Effectiveness of Recurrent Neural Networks” made splashes last year. The basic premise is that you can create a recurrent neural network to learn language features character-by-character. But is the resultant model any different from a Markov chain built for the same purpose? I implemented a character-by-character Markov chain in R to find out.…Continue
