I don’t believe the issue of stock market noise has received much attention from professionals in the investment industry. I am uncertain if it is much of a topic even among traders. It certainly wouldn’t be unusual for noise to be discussed among data scientists. Consider the implications of the suggestion that some trading days provide better guidance than other days – and that analysts should be focused on days that contain less “noise.” The quality of one’s guidance becomes…Continue

Perhaps to no one’s surprise, the growth in companies implementing Big Data and Analytics projects continues to climb – as evidenced by the continued growth in data lakes. As most companies begin to implement their Big Data and Analytics strategy, they struggle to show value for their efforts. This can come from several areas:

Introduction: Deriving meaningful information out of heap of data is the minimal requirement for any establishment today for its survival & sustenance. There are many terminologies and buzz words related to this area that blurs the meaning leaving people confused, such as Bigdata, Data Ware house (DWH), BI analytics, AI (Artificial…Continue

I read an article this morning, about a top Cornell food researcher having 13 studies retracted, see here. It prompted me to write this blog. It is about data science charlatans and unethical researchers in the Academia, destroying the value of p-values again, using a well known trick called p-hacking, to get published…Continue
Conversational user interface (UI) is changing the way that we interact. Intelligent assistants, chatbots and voice-enabled devices, like Amazon Alexa and Google Home, offer a new, natural, and intuitive human-machine interaction and open up a whole new world for us as humans. Chatbots and voicebots ease, speed up, and improve daily tasks. They increase our efficiency and compared to humans, they are also very cost effective…Continue

There has been much hype surrounding deep learning and data science learning in recent times, and one of the cornerstones of deep learning is the neural network. In this article, we will look at what a neural network is and get familiar with the relevant terminologies.
In simplest terms, a neural network is an interconnection of neurons. Now the question arises, what is a neuron? To understand neurons in deep learning, we first…Continue

Feature selection and engineering are the most important factors which affect the success of predictive modeling. This remains true even today despite the success of deep learning, which comes with automatic feature engineering. Parsimonious and interpretable models provide simple insights into business problems and therefore they are deemed very valuable. Furthermore, in many occasions the underlying size and structure of the data being analyzed may not allow the use…Continue

Data Scientists are considered to be highly technical professionals and are typically seen exercising their talent in conventional business industries. However, Data Science is a problem-solving field. Therefore, it can be applied in any field that uses set of data and determines patterns to make decisions. For this reason, Data Scientists have the ability to add value to non-profit organizations.
Like many other business organizations,…Continue

Guest blog post by Zied HY. Zied is Senior Data Scientist at Capgemini Consulting. He is specialized in building predictive models utilizing both traditional statistical methods (Generalized Linear Models, Mixed Effects Models, Ridge, Lasso, etc.) and modern machine learning techniques (XGBoost, Random Forests, Kernel Methods, neural networks, etc.).…Continue
Okay, I am weird (tell me something that I don’t know, say most of my friends). For Christmas I wanted a Nike Apple Watch to go with my existing FitBit and Garmin fitness trackers (I look sort of like a cyborg in the photo below…which is always cool).
While I was intrigued by the ability to do all sorts of cool things on the…Continue

Today’s Artificial Intelligence (AI) discussions remind me of a Steve Martin skit from the early Saturday Night Live days (1979). In the skit titled “What the Hell is that?”, Steve Martin, later joined by Bill Murray, is looking in the distance at something, repeatedly asking the question “What the hell is that?” The skit reminds me of today’s AI discussions about “What the hell is AI?”, which distracts from…Continue

For most businesses, machine learning seems close to rocket science, appearing expensive and talent demanding. And, if you’re aiming at building another Netflix recommendation system, it really is. But the trend of making everything-as-a-service has affected this sophisticated sphere, too. You can jump-start an ML initiative without much investment, which would be the right move if you are new to data science and just want to grab the low hanging fruit.
One of ML's…Continue

On Linkedin, many Data Science enthusiasts who aspire to be Data Scientists follow me.
One person asked the question:
What do I need to know to get a $150K job as a Data Scientist?
It’s a good question
Because you can find Data Scientist jobs paying as little $30K and…Continue
Recently, I encountered the mystery of a stock trading algorithm that habitually makes the wrong investment decision. It is usually wrong 55 to 60 percent of the time. This algorithm makes use of simulated traders – usually a thousand of them. Each trader is triggered to do buy and sell orders using a purely technical approach – that is to say, by analyzing the price. I call the simulated traders that make money “the Nogs.” By definition, all of the Nogs are winners. …Continue

Scene from The Incredibles 2
Promising data-minded individuals are easy to spot from the distance: curious detailed-oriented thinkers, energized by uncertainty, open to opposed opinions and willing work in team iteratively to produce insightful recommendations, but still with feet on the ground.
The analytics job market is nascent and…Continue
