The One-Stop Shop for Big Data Today, I’m going to explain in plain English the top 10 most influential data mining algorithms as voted on by 3 separate panels in this survey paper. Once you know what they are, how they work, what they do and where you can find them, my hope is you’ll have this blog post as a springboard to learn even more about data mining. What are we waiting for? Let’s get started! Here are the algorithms:

New Tool Puts Dollar Value on Social Projects Measuring the social impact of building low-cost housing, child-care centers, and health clinics in poor neighborhoods isn’t easy. But a new online tool takes a stab at putting a dollar value on such building projects, based on the best available social-science research. The Social Impact Calculator is the result of the Low Income Investment Fund’s effort to measure the effect of its own work. The fund couldn’t afford to do long-term studies on the people whose lives have been touched by the apartment buildings, schools, and clinics it finances. So the group sought out high-quality research that allows it to estimate a monetary value, says Nancy O. Andrews, chief executive of the Low Income Investment Fund.
Data journalism at the Guardian: what is it and how do we do it? Data journalism. What is it and how is it changing? Photograph: Alamy Random forest The selection of a random subset of features is an example of the random subspace method, which, in Ho's formulation, is a way to implement classification proposed by Eugene Kleinberg. History The early development of random forests was influenced by the work of Amit and Geman which introduced the idea of searching over a random subset of the available decisions when splitting a node, in the context of growing a single tree. The idea of random subspace selection from Ho was also influential in the design of random forests. In this method a forest of trees is grown, and variation among the trees is introduced by projecting the training data into a randomly chosen subspace before fitting each tree.

Larger values were represented by small dark gray or black squares (pixels) and smaller values by lighter squares.
Accelerating Social Impact CCC Pollster Doug Miller in his recently published book, “Can the World be Wrong?” predicts social enterprise ‘as the next big thing’ as we face “the ever-increasing pressure on business to act better in society’s interest…” His prediction just might be confirmed by the amazing shifts and developments in the social enterprise arena across Canada in 2015. We have witnessed public policy changes, market growth, increased social impact reporting and emerging new partnerships all contributed to a more vibrant social enterprise sector. Some of what we’ve witnessed in 2015…
Starting Your Big Data Lab for a POC In continuation of my previous blog post, “6 Steps to Start Your Big Data Journey,” I want to address here the question “How should you start your big data journey?” What is the Big Data Lab? The Big Data Lab is a dedicated development environment, within your current technology infrastructure, that can be created explicitly for experimentation with emerging technologies and approaches to big data and analytics. Should foundations be playing a greater role in social investment? Just when you think you have dealt with one issue, for example, the availability of regular loans to charities, through Charity Bank, up pops another challenge – what about smaller, unsecured loans? Just when we’ve done that, through the Social Investment Business (SIB) and CAF Venturesome, along come charities and social enterprises asking “What about some finance involving equity, where I only start repaying you when the income stream we grow is up and running?” A raft of social enterprise venture funds later, along come community groups looking to raise community shares. So how do we support that?
