Coursera: Data Science in Education

Monica Rogati in The LinkedIn Blog on Coursera, which offers free online courses: “Coursera’s approach to feedback and assessment is a very interesting application of data science. Tests are either computer-graded or peer-graded — the latter following industry tested crowdsourcing best practices (clear instructions, gold standards, training, qualification tasks assessor agreement monitoring etc.). Peer grading isn’t just treated as a means for scaling — it is part of the learning process. One of Daphne’s charts showed that students significantly improved on subsequent tests after peer- and self-grading. Interestingly, the better students learned even more from self-grading than from grading others…    Continue reading

A Very Short History of Big Data

In addition to researching A Very Short History of Data Science, I have also been looking at the history of how data became big. Here I focus on the history of attempts to quantify the growth rate in the volume of data or what has popularly been known as the “information explosion” (a term first used in 1941, according to the OED). The following are the major milestones in the history of sizing data volumes plus other “firsts” or observations pertaining to the evolution of the idea of “big data.”

Imagination and Data Science

Today in 1833, Ada Byron (later Countess Lovelace) met Charles Babbage when visiting his house to see a portion the Difference Engine, or what her mother, Lady Byron, called his “thinking machine.” James Gleick writes in The Information: “Babbage saw a sparkling, self-possessed young woman with porcelain features and a notorious name, who managed to reveal that she knew more mathematics than most men graduating from university. She saw an imposing forty-one-year-old, authoritative eyebrows anchoring his strong-boned face, who possessed wit and charm and did not wear these qualities lightly. He seemed a kind of visionary–just what she was seeking. She admired the machine, too.”

With the Analytical Engine, Babbage imagined the modern computer. Gleick quotes Ada on imagination, from an essay she wrote in 1841: “It is that which penetrates into the unseen worlds around us, the worlds of Science. It is that which feels & discovers what is, the real which we see not, which exists not for our senses. Those who have learned to walk the threshold of the unknown worlds… may then with the fair white wings of Imagination hope to soar further into the unexplored amidst which we live.”

In this she anticipated Albert Einstein’s much-quoted observation: “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”

Note to Data Scientists (or more specifically, those making exaggerated claims about IBM’s Watson or the promise of “data-driven” science): Without our imagination, machines can’t learn.
