Greetings and Welcome!
My name is Ryan Anderson. I'm a founding investor and board member of Dream to Learn. I am also a very keen Data Analytics and Visualization "enthusiast"
I founded this community for two main reasons :
- To seek (and offer) knowledge related to the huge variety of tools available on the web, and create a community of like-minded people who were just as keen on data, analytics and visualizations as I am. What I lack in expertise, I hope to make up for in enthusiasm.
- To exercise the Dream to Learn platform during Alpha testing, late in 2013, and beyond. I believe this is a great topic, as it's got a large following, as well as huge potential for both curation of existing web assets, and also generation of new thought pieces and information for community members.
We are very excited about the community. I'm not sure exactly what shape it will have in 2 weeks, 2 months or 2 years, but there are a few areas I've been exploring recently that I'm going to focus on initially, that I hope will be of interest to others:
- Visualization League Table: D3 http://d3js.org/ and Raphael are just a couple of amazing tools that exist for data viz. I'm going to
- Topological Data Analysis (TDA) - http://en.wikipedia.org/wiki/Topological_data_analysis . In a nutshell, it's showing high-dimensional structure in low-dimensional visualizations. Put another way, imagine you have a data set with lots of dimensions (i.e. columns) - and want to distill it down to a 3-D or 2-D image, using a lens that focuses on things that matter. That's TDA.
- Excel - I've been using excel for many years, and it's powerful and useful - especially for a first cut of a data set, to start to get a feel for what you're looking at.
- R Programming Language - I'm still a novice with R http://www.r-project.org/ and http://en.wikipedia.org/wiki/R_(programming_language) but I have had success with it, and it's got a very active community in many dispersed groups. It's my hope that this Dream to Learn community will help augment other communities, or perhaps serve as a hub for some.
- Data checking and Data Cleanup tools - Like OpenRefine (ex-Google Refine) http://openrefine.org/ ; also http://jsonlint.com/
- Machine Learning - I have friends at http://about.wise.io/ Wise.IO who are very skilled at working with data. They've got a pretty cool beta tool that is ML as a service (MLaaS). If you're keen to be doing handwriting recognition (predicting digits from written samples) in less than 20m, this is a fun area to explore. The random forest classification and prediction is a very adaptable tool for many problems.
I hope you enjoy the community - if questions or suggestions on ways to improve it, please let us know,
