This book presents a methodology and philosophy of empirical science based on large scale lossless data compression. In this view a theory is scientific if it can be used to build a data compression program, and it is valuable if it can compress a standard benchmark database to a small size, taking into account the length of the compressor itself. This methodology therefore includes an Occam principle as well as a solution to the problem of demarcation. Because of the fundamental difficulty of lossless compression, this type of research must be empirical in nature: compression can only be achieved by discovering and characterizing empirical regularities in the data. Because of this, the philosophy provides a way to reformulate fields such as computer vision and computational linguistics as empirical sciences: the former by attempting to compress databases of natural images, the latter by attempting to compress large text databases. The book argues that the rigor and objectivity of the compression principle should set the stage for systematic progress in these fields. The argument is especially strong in the context of computer vision, which is plagued by chronic problems of evaluation. The book also considers the field of machine learning. Here the traditional approach requires that the models proposed to solve learning problems be extremely simple, in order to avoid overfitting. However, the world may contain intrinsically complex phenomena, which would require complex models to understand. The compression philosophy can justify complex models because of the large quantity of data being modeled (if the target database is 100 Gb, it is easy to justify a 10 Mb model). The complex models and abstractions learned on the basis of the raw data (images, language, etc) can then be reused to solve any specific learning problem, such as face recognition or machine translation.
Panasonic and Nuance have been close partners on TV voice recognition in the past; we now know that they're getting a bit cozier for Panasonic's 2013 Smart TVs. The engine will also speak out content and menus if you need more than just visual confirmation of where you're going. Panasonic's refreshed TV line is gradually rolling out over the spring, so those who see a plastic remote control as so very 2010 won't have long to wait. Panasonic's New Smart TVs Now Listen and Speak with Nuance's Dragon TV Panasonic's New SMART VIERA HDTVs Voice Interaction Lets People Find TV Content, Search the Web, Get Access to Apps and More with the Power of Dragon Now people can simply sit back and speak to find content, search the web, control volume and more – creating a more interactive and intelligent television experience. And with Dragon TV's text-to-speech, television content and options on the screen can be read aloud.
The Japanese automaker unveiled its new 2019 Subaru Forester at the New York International Auto Show on Wednesday. It's largely similar to previous Foresters, but there's one major upgrade: It now has a facial recognition feature. Okay, so it's not quite as sophisticated as the iPhone X's Face ID, which has a 1-in-1 million false acceptance rate and opens the phone like a password. But Subaru's DriverFocus software, which makes its global debut in the 2019 Forester, still has some cool perks. Don't forget your keys, though, because the feature won't open the car or start it for you.
Facial recognition algorithms are being trained using photos of people who have not given their consent, legal experts have warned. Companies like IBM are scraping millions of publicly available images from Flickr and other sites in order to improve the technology, though the people in the photos have no idea this is happening. Civil rights activists warn that this technology could one day be used to track and spy on the same people whose faces have been used to train it. We'll tell you what's true. You can form your own view.
Apple has unveiled a completely redesigned iPad Pro, with a new look and entirely new insides. The most obvious changes to the tablet are the disappearance of the home button and a vast reduction in the bezels that sweep around the front, so that the screen can take up almost all of the front of the tablet. In place of the home button's Touch ID sensor, previously used to unlock it, has come the Face ID facial recognition technology that first arrived with the iPhone X. The new iPads borrow heavily from that phone, in both its design and the features contained within. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
