Becoming a Data Scientist: What a Data Scientist ISN’T

If you’re reading this you probably already have an inkling of what a data scientist is. Have you ever considered what a data scientist isn’t? According to Vincent Granville, author of Developing Analytic Talent: Becoming a Data Scientist, data scientists are: Not statisticians Not data analysts Not computer scientists Not software engineers Not business analysts Data scientists do have some knowledge in each of these areas but also some outside of these areas. NEITHER STATISTICIANS NOR DATA ANALYSTS: One reason the gap between statisticians and data scientists has grown over the last 15 years is that academic statisticians, who publish theoretical articles (sometimes not based on data analysis) and train statisticians, are… not statisticians anymore. Also, many statisticians think that […] Continue Reading

Normal Distribution Curve

In the orange juice problem, you’re trying to blend juices to take out variability, so is it reasonable to expect that the product you’re getting from your suppliers In the orange juice problem, you’re trying to blend juices to take out variability, so is it reasonable to expect that the product you’re getting from your suppliers won’t have variable specs? Chances are that shipment of Biondo Commune orange juice you’re getting from Egypt won’t have an exact 13 Brix/Acid ratio. That may be the expected number, but there’s probably some give around it. And oftentimes, that wiggle room can be characterized using a probability distribution. A probability distribution, loosely speaking, gives a likelihood to each possible outcome of some situation, […] Continue Reading

Becoming A Data Scientist: Corporate and Association Training Programs

A few universities and other organizations have started to offer data science degrees, training, and certificates. Conferences and competitions also exist for people serious about adding credentials as data scientists. Corporate and Association Training Programs, Conferences and Competitions Both private companies and professional organizations offer certifications or training. Here are a few of them: INFORMS (Operations Research Society): Analytics certificate Digital Analytics Association: certificate TDWI (The Data Warehousing Institute): Courses; focus is on database architecture American Statistical Association: Chartered statistician certificate Data Science Central: Data science apprenticeship International Institute for Analytics: More like a think tank.

Optimization Modeling: Because That Fresh Squeezed Orange Juice Ain’t Gonna Squeeze Itself

When you were a child, perhaps there came that day when someone explained to you that Santa Claus didn’t exist, outside of men with bad rosacea dressed up at the mall. Well, today I’m going to shatter another belief: your not-from-concentrate premium orange juice was not hand squeezed. In fact, the pulp in it is probably from different oranges than the juice, and the juice has been pulled from different vats and blended according to mathematical models to ensure that each carafe you drink tastes the same as the last. Consistent taste in OJ year round isn’t something that just anyone can pull off.  Oranges aren’t in season in Florida year round. And at different times of the year, different […] Continue Reading

Communication – How to Optimise Businesses

What moves faster the denser you go into it…communication My name is Simon Lavender a Data Scientist at Hunterlodge Advertising (and yes, I came from a science background).   Standardising methodology, using communication allows for better reinvestment of time…it is time that is a finite resource and in an ever more open world, competition is just as large. However, from a background initially in charity (having graduated in Quantitative Genetics) I realised it was the awareness that was key…for 10 years you could go travel an inefficient way to work, then realise a better way.  To you, that route was fine/adequate/efficient, amongst other reasons you didn’t have time to consider it.   Step back, challenge the status quo.  Reflect and consider […] Continue Reading

Cool Infographics: Effective Communication with Data Visualization and Design

Wiley extracts at Big Data Week – the Big Data Week team will be posting extracts from great books and resources available through Wiley during the festival. Today we’re looking at infographics. By Randy Krum ISBN: 978-1-118-58230-5 Extract taken from Chapter 4: Infographic Resumes The definition of an infographic resume is: A visual account of an individual’s history and abilities that uses data visualization design to communicate key portions of a job candidate’s skills, history, education, or other relevant information. The key distinction that makes infographic resumes unique is that the graphic elements visualize important information and help tell a better story about the job candidate. It’s not just about adding graphic elements but communicating data or information more effectively. […] Continue Reading

Inside Big Data Week Chicago 2014: Loyola University Wants to Help Businesses Understand How to Interpret their Data

From 1 pm to 5 pm on Tuesday May 6, 2014, the Center for Risk Management at Loyola University’s Quinlan School of Business is presenting “Translating Big Data into Business Decisions.” The goal of the event is to highlight how the value of Big Data is not derived solely from statistics, but from an established business process that requires sound managerial judgment to guide the analytics. This process is what allows managers to leverage their big data to identify the actionable insights to drive better business decisions. We asked Fady Harfoush, PhD, and Director of Quinlan’s Financial Services & Business Analytics Lab a few questions about the event, why it is vital to establish a process when implementing a big […] Continue Reading

Grains of Data from the Sahara

Co-founder of Big Data Week, Ande Gregson, will be one of the many competitors joining the annual gathering in Morocco in the Sahara desert for the Marathon des Sables in April 2014: A six-day, 250k self sufficient ultra marathon, which is the equivalent of six regular marathons, considered to be the toughest foot race on Earth. However, unlike most of the competitors, he’ll be using a number of wearable devices to measure his physiological attributes as part of Quantified Self project tracking his heart rate, breathing rate, race pace, marathon speed and all round performance; coupling the vital statistics and with HD video footage from his own perspective to produce a short documentary of the experience. Running with an 8kg […] Continue Reading
