New York City taxi trips For several years, taxis in New York City have had GPS receivers to record the location of the start and end of every trip, but the data has never been made available to the general public. Chris Whong and Andrés Monroy used New York’s Freedom of Information Law to request a copy of the taxi records from 2013 and publish them on the web. New York taxi pickups and dropoffs It is a fascinating data set, one of the densest I’ve ever seen.

The Great Wave of Kanagawa The Great Wave off Kanagawa The Great Wave off Kanagawa (神奈川沖浪裏) is one of the most well-known Japanese prints of all time. It’s also a great metaphor for better understanding the diverse nature of data visualization. Created around 1830 by Japanese artist Katsushika Hokusai (1760–1849), The Great Wave is a remarkable example of the ukiyo-e style, an expressive genre of woodblock printing that flourished in 17th-century Japan. Application of Pascal’s Triangular Plus Monte Carlo Analysis to Appraise the Wisdom of Crowds Following to the article of “Application of Pascal’s Triangular Plus Monte Carlo Analysis to Calculate the Risk of Expected Utility” on link: the purpose of this article is to appraise the wisdom of crowds by using of a simulation model which is the combination of Pascal’s Triangular method and Monte Carlo simulation model. The most important finding is to be proved the research study conducted in 1906 by the British scientist Sir Francis Galton (1822 – 1911) in the case of the Wisdom of Crowds in which we can say there is a very good adaptability between the mathematical models and Human’s sense. I think that we can also use from this simulation model for Market Predictions.
Making Business Decisions Easier with Data Visualizations Informed decision making is the foundation upon which successful businesses are built. As a decision maker for your business, you need access to highly visual business intelligence tools that can help you make the right decisions quickly. As your organization grows, so does the amount of collected information. If this data is delivered to you in spreadsheets or tabular reports, it becomes more and more challenging to find the patterns, trends and correlations necessary to perform your job well. Effective data visualization is an important tool in the decision making process.
Info - Latests News about MongoDB Nearest neighbor models are conceptually just about the simplest kind of model possible. The problem is that they generally aren?t feasible to apply. Or at least, they weren?t feasible until the advent of Big Data techniques. This talk will describe some of the techniques used in the knn project to reduce thousand-year computations to a few hours.
World Map of Social Networks January 2017: a new edition of my World Map of Social Networks, showing the most popular social networking sites by country, according to Alexa & SimilarWeb traffic data (caveat: it’s hard to understand the impact of Google+ because it is part of Google domain traffic). There are a lot of news since last January: Facebook is still the leading social network in 119 out of 149 countries analyzed, but it was stopped in 9 territories by Odnoklassniki, Vkontakte and Linkedin. It’s interesting to see that in some countries, like Botwana, Mozambique, Namibia, Iran e Indonesia, Instagram wins and that some African territories prefer LinkedIn. Overall LinkedIn conquers 9 countries, Instagram 7, meanwhile VKontakte and Odnoklassniki (part of the same group Mail.ru) grow up in Russian territories.
High crime rates explained by gasoline lead. Really? Crime rates in big cities (where gasoline concentration is high) peaked about 20 years after lead was banned in gasoline, according to an econometric study by Rick Nevin. The 20 year time lag being the time elapsed between lead exposure at birth, and turning into a 20 year old criminal. At least, that's the argument proposed by some well known econometricians, based on crime rates analysis over time in large cities. In my opinion, this is another example of of study done using the wrong kind of design of experiment, where statistical science is being abused or misused by people who claim to be experts.
