LAK11: Big Data Small Data « Viplav Baxi's Meanderings - 0 views

  • which data is more appropriate - BIG or small
  • most discussion about big data centres on quantity
  • other elements you mention – implication, new models, new decision making approaches – all flow from this abundance of data.
  • ...15 more annotations...
  • Increased data quantity requires new approaches
  • Is small beautiful? Look at the following links. Big Data, Small Data New Age of Innovation (Prahalad) So you like Big Data
  • reading on Insurers and the work done by Levitt and Dubner on Freakonomics tells us clearly that data not earlier thought relevant or causal can be an efficient predictor.
  • Secondly, strategies designed on BIG data
  • may overpower small data strategies
  • Thirdly, BIG data also has BIG impacting factors.
  • Fourthly, actions taken on BIG data will have big consequences,
  • Lastly, if everybody, big or small, started using BIG analytics, to make decisions
  • companies would anyway lose the competitive differentiator that analytics brings to them.
  • Corresponding to the question, how big does BIG need to be, the question I have is - how small really is small.
  • defining patterns that emerge from very small pieces of data (e.g. synchronicity)
  • how tools for SNA and analysis of BIG data can apply to Learning and Knowledge Analytics
  • at the other end it embraces how small changes can cause long term variations
  • not easy to analyze the small data
  • data that is small enough not to be generalizable

Book Excerpt: The Numerati by Stephen Baker - BusinessWeek - 0 views

  •  
    BusinessWeek's 2006 Cover Story, "Math Will Rock Your World," announced a new age of numbers. With the rise of new networks, the story argued, all of us were channeling the details of our lives into vast databases. Every credit-card purchase, every cell-phone call, every click on the computer mouse fed these digital troves. Those with the tools and skills to make sense of them could begin to decipher our movements, desires, diseases, and shopping habits-and predict our behavior. This promised to transform business and society. In a book expanding upon this Cover Story, The Numerati, Senior Writer Stephen Baker introduces us to the mathematical wizards who are digging through our data to decode us as patients, shoppers, voters, potential terrorists-even lovers.

Nothing New About Asking Questions. The Right Ones. - Neoteny - 0 views

  •  
    There are plenty of reasons to be skeptical about the BD market. But big data probably deserves a place in overall enterprise IT strategy for generating business insight. Best practices include generating a list of important challenges or questions that the current approach to data does not address. Could big data deliver the answers enterprises are looking for? If so, then it's all about discipline. A disciplined, targeted approach to big data - one focused on answering very specific questions. (my emphasis - I'll get to those later)

Nuts and Bolts: How to Evaluate e-Learning by Jane Bozarth : Learning Solutions Magazine - 3 views

  • The linearity and causality implied within the taxonomy (for instance, the assumption that passing a test at Level 2 will result in improved job performance at Level 3) masks the reality of transferring training into measurable results. Many factors enable — or hinder — the transfer of training to on-the-job behavior change, including support from supervisors, rewards for improved performance, culture of the work unit, issues with procedures and paperwork, and political concerns
  • Robert Brinkerhoff takes a systems view of evaluation of training, believing it should focus on sustained performance rather than attempting to isolate the training effort:
  • learn best from the outliers
  • ...4 more annotations...
  • The method asks evaluators to: Identify individuals or teams that have been most successful in using some new capability or method provided through the training; Document the nature of the success; and Compare to instances of nonsuccess.

  • training as part of a system
  • a means of formative as well as summative evaluation.

Datawocky: More data usually beats better algorithms - 0 views

  • This simple change made Google's ad marketplace much more efficient than Overture's. Notice that the algorithm itself is quite simple; it is the addition of the new data that made the difference.
  • Of course, you have to be judicious in your choice of the data to add to your data set.
  •  
    But the bigger point is, adding more, independent data usually beats out designing ever-better algorithms to analyze an existing data set. I'm often suprised that many people in the business, and even in academia, don't realize this.
