If you are interested in initiating and organizing a community, you may be interested in this talk. For instance, why are some people volunteering to run a community conference like PyCon? One of the reason is "because it is fun". This talk will show you what's the fun and how to create the fun. ? 簡介 Description ? Emergence is commonly seen in the nature and humanity. For example, the stock market. The basic elements of social systems are human beings, and the mutual social bonds of human beings in the social system a.k.a. the stock market in our example, perpetually changes in the sense of the ongoing reconfiguration of the structure of the stock market. The stock market is the emergence of human beings in the end. Any kind of community is also the emergence of the human beings, including the community to organize a community conference. I have volunteered to organize a regional PyCon, PyCon Taiwan, for years. I observed some "small" and "big" emergences arising from the community, including the organizing team and general participants. Let me talk about what I have seen and how we may initiate the emergence of a community. ? 關於講者 About Speaker - Taihsiang Ho (tai271828) ? FLOSS contributor. Scientific computing amateur.

Speaker: Muyueh Lee http://blog.muyueh.com/real-time-visualization-with-python-and-d3-js/ Pyhton has great power in scrapping and analyzing data, and D3.js is a great tool for building visual interface. In the first part of the talk, I will demonstrate how to set up D3.js as an interactive layer on top of Python. In the second part of the talk, I will show what it can achieve, by using the "Taiwan Vegetable Auction" dataset (past 10 years transaction data of 127 kinds of vegetable, 1GB). The dataset is too large for human to see through, a machine learning algorithm will be able to fit a regression model on the dataset, but it can't make sense of it. For example, in the following graph: You can see the average price of green onion in different markets for the past 20 years, the fluctuation between different markets are similar, yet since 2010, there is a perfectly horizontal blue line: while price in the other markets have changes, price in "Taitung" has remained exactly the same, suggesting a possible case of monopoly. One can then asks the system to detect other cases of monopoly. This process of exploratory data analysis can only be possible with both machine and human. From a technical perspective, this talk can benefit front-end developer/data scientist to set up such a system. Yet a more profound value of the talk will be to explore how machine and human can work together. About the speaker Muyueh Lee (李慕約) is a programmer focus on Data Visualization, for profit and for fun, he hosts "Visualization Lighting Talk", a gathering for programmers doing data visualization work in Taiwan, and has been teaching Visualization in the graduate school of Journalism at National Taiwan University, in the DataScience Program by CfT and SYSTEX, and held various workshop in Guangzhou and Hong Kong.
