DESCRIPTION

This is a talk I gave on Jan 31, 2014 as part of Harvard's Institute for Applied Computational Science (IACS) seminar series. Abstract: When solving problems, data scientists often encounter added layers of complexity when the problems to be solved are not well defined, and their solutions unclear. In these cases, standard, more straightforward approaches fall short, as they are not amenable to vague problems, and are thus not guaranteed to reliably produce useful results. At Datascope Analytics, we adopt methodologies from the design community and use a "continuous feedback loop" to iteratively improve dashboards, algorithms, and data sources to ensure that the resulting tool will be useful and well received. During this talk, I will illustrate our approach by sharing a detailed example from one of our projects.

data science & the design process fickleness and how we solve it

design is a process.

the data

•  every person has attributes: function, location, division, etc

the data •  everyone is encouraged to write about their

work •  when people write, they are encouraged to

write together •  most people took a survey

On Chemical X and its Y-related effects on diaper absorption

Lorem Ipsum is a dummy text used when typesetting or marking up documents. It has a long history starting from the 1500s and is still used in digital millennium for typesetting electronic documents, page designs, etc. In itself, the original text of Lorem Ipsum might have been taken from an ancient Latin book that was written about 50 BC. Nevertheless, Lorem Ipsum's words have been changed so they don't read as a proper text.  Naturally, page designs that are made for text documents must contain some text rather than placeholder dots or something else. However, should they contain a proper English words and sentences almost every reader will deliberately try to interpret it eventually missing the design itself.  However, a placeholder text must have a natural distribution of letters and punctuation or otherwise the markup will look strange and unnatural. That's what Lorem Ipsum helps to achieve.

I would like to thank Peppermint Patty for her support on studying Chemical X, as well the infinite wisdom of

Linus van Pelt and his willingness to use his blanket in my experiments.
