I’ve been working on a fun problem lately that involves estimating a scalar parameter from a set of repeated observations. It turns out that in certain circumstances, the presence of noise in the system can actually make the estimate more accurate, which is a little counterintuitive and also kind of cool. In my case, I... View Article

I’ve got a new blog post up at EE Times, talking about how to build video devices for the Internet of Things: Video cameras are uniquely compelling sensors because vision is our dominant sense.

I was interviewed by Xconomy today in a piece entitled “Could Fallout from Aereo Ruling Have “Chilling Effect On Startups?” Here’s a little more analysis than what was covered in the Xconomy article. The question of how the decision would affect innovation was raised immediately after the ruling by Chet Kanojia, Aereo’s CEO, when he... View Article

Recently we tweeted an interesting article on big data, from the Financial Times. The author’s key point is that sampling bias and sampling error are possible even with large data sets. As illustration, the author discusses a classic case where the Literary Digest incorrectly predicted that Alf Landon would beat FDR in the 1936 election.... View Article

I had the pleasure of attending and speaking at the EE Live Internet-of-Things conference in San Jose last month. Since then, I’ve been reflecting on some of the bleeding edge technical concepts that were discussed there. It occurs to me that many of the IoT devices we are asked to design act as a standalone...
