Ray Kurzweil Ted Videos on Dinosaur Extinctions
Our of our most popular posts have touched on Ray Kurzweil themes of the Singularity as well as Ray Kurzweil’s decades-old ideas on wearables that appear to have inspired Google Glass. We noticed he’s done at least one additional Ted Talk since we ran our articles. (Oh. We needed a photo for an earlier version this, so we did this glitch art of the earlier Singularity-themed photo:) Kurzweil had quite a career. After coming to national prominence at an early age on a national quiz show for his computer-generated music (in the old Black & White mainframe days), he invented a reading machine for the blind (and OCR and speech synthesis in the process). He went on to start a eponymous music synthesizer company (one of many successful companies he’s founded). Recently he founded Singularity University and did a stint at Google working on artificial intelligence. The predictions in his best-selling books and videos, based on Moore’s law, have been eerily accurate.… Read the restTed Talks on IBM Watson & Bayes’ rule in evolution
Some of our most read articles have been on IBM Watson, including suggestions & possible alternatives. We’ve pushed IBM several times to come up with better demos for Watson in a business context. This author went to a demonstration by IBM of Watson in August 2014, an witnessed an overglorified AltaVista demonstrated by an engineer. (AltaVista was the dominant Internet search engine prior to Google. Both Google and AltaVista can handle natural language question-like syntax in search queries, although users tend not to use since it just adds boilerplate text. Similar to AltaVista two decades ago, this Watson demonstration would some respond to questions by coming up with partially-related excerpts from various web pages from a small medical database on the web. It had difficultly understanding many simple questions, and the clips selected weren’t always the most appropriate responses. It didn’t look like this thing was a Jeopardy! champion. As the engineer was told, this is bleeding-edge technology; if you want to sell it to businesses, you need to make the case.… Read the restHamming distance: Crazy Quilt Error-correcting Codes
Shown here are Hamming distance error-correcting codes in an illustration resembling a crazy quilt. In yesterdays’ post we pondered that aliens looking at the Sagan-designed Pioneer Plaque might have a hard time finding Earth due to the various data error. (These were due to the limits of science back in the 1970s.) Some people might regard the errors as a good thing. (Maybe we don’t want aliens to find us. 🙂 But there is some redundancy in the Quasar timing uses. (In part, there had to be, because the timings will slowly change.) Sending a message with extra, redundant information to help the receiver correct errors is known in coding theory as a Forward Error Code. Space aliens trying to decipher the plaque might have to use something more advanced — probably based on Bayesian statistics, the sort of statistics error-detecting and correcting algorithms we’re starting to see in advanced artificial intelligence algorithms that use statistical inference.… Read the restWolfram mathematica: data visualization example
This is example of visualization using Wolfram Mathematica, a commercial software package. We’ve previously discussed some of Wolfram’s other products and ideas in an earlier post on digital physics and cosmology as well as in our posts on IBM Watson. One of the reasons that data visualization remains something of a black art is that there are so many data visualization packages out there. Each package has its strength in a few kinds of plots or types of visualizations. Some of the better packages are commercial (and, unfortunately, not necessarily inexpensive). The high prices mean the experience of any practitioner is likely to be limited to a few commercial visualization packages over the course of a career (since most sites will only license a few packages). Open source data visualization packages are therefore very powerful, since they potentially combine the best of free tools. There are very good free tools out there.… Read the restRecent Comments
