I think the most important takeaway from this semester is how important data and understanding it is. This course has given me basic but important skills that I’ve already been able to utilize in group projects and at my job. I would say this course is about introducing basic computational style thinking and methods. Having gone through this…[Read more]

A data driven service I use regularly is Adobe Kuler. Kuler allows people to create and share 5 color schemes and is very useful for graphic artists. The rows in the spreadsheet would represent each color scheme that is created. The columns would represent things like what 5 colors make up the scheme, how many times the scheme is clicked, how many…[Read more]

I thought this article was interesting because it gives fairly good evidence that working longer hours does not always relate to increased productivity. The British munitions factory workers had about 44 good working hours a week before productivity…[Read more] -

A KPI I use on a regular basis is Lifts/Average At Strength Level. It is specific because it can set specific standards in pounds for the next gym session. It’s measurable because it uses my direct input in pounds, which are clearly labeled on weights, and compares it to a database of other users. I use it often to set attainable and measurable…[Read more]

I have a horrible habit of not backing up the work that I do. In one case, I had been working on a statement of values worksheet for one of my company’s largest clients. Naturally there were thousands of rows, and the project was going to take me a few weeks to get through. There were multiple times where I realized that I had either been p…[Read more]

Data collected from the Compact Muon Solenoid experiement (a main detector in the Large Hadron Collider) was released to the public through the CERN Open Data Portal. In the field of particle physics, open data has not been widely used for fear of…[Read more] -

I think “Explore” is the most important principle on data visualization. Having the ability to create something like a heat-map or other type of exploratory data visualization can help us discover things we might have had trouble discovering otherwise. This explore principle would come in handy for problems that are hard to solve by directed…[Read more]

From what I’ve seen data science is having a large impact in the risk management and insurance industry. Insurance carriers continue to use more advanced data analysis and science to underwrite more effectively and also to optimize their reserves. This interest in data science and analytics has also lead to the growth of the “insurtech” segment of…[Read more]

I found a data set from OpenDataPhilly listing the aggregate energy usage and environmental impact of different types of public and private sector buildings in Philadelphia. I thought the associated map and data visualization were very interesting and showed, in an interactive way, which types of buildings were using the most energy and giving off…[Read more]

Facial Recognition technology is rapidly improving and is approaching the ability that humans have of reading faces. This could potentially have a huge impact on privacy as facial recognition is unlike any other kind of biometric…[Read more] -

A piece of conventional wisdom I’ve heard is “past performance of active managers is indicative of future performance.” The data I would collect to test the theory is the annual returns of different actively managed funds to see how many were consistent over time.
