Skype can translate spoken Spanish to English in near real-time

Kif Leswing  Dec. 15, 2014 – 9:17 AM PST

Microsoft started rolling out a new feature for Skype on Monday: Skype Translator will translate communications from users using different languages in near real-time — that is, as you’re chatting. At first, Skype Translator will work with spoken English and Spanish, as well as forty written languages over instant messaging.

To try it out, you’ll need a computer running Windows 8.1 or a current Windows Phone. You can sign up for the preview here. Users of Skype Translator will need to manually activate the feature for each person they speak to in order to hear their conversation automatically translated. The software will also provide an on-screen transcript of the call.

Machine Learning: Optimizing How WindTurbines Work (Video)

October 31, 2014
By Ulrich Kreutzer – Siemens, Pictures of the Future,
Wind parks produce their own air circulation dynamics. First row turbines get more wind than those in the middle. They also produce vortices that affect the performance of downstream turbines. Learning software can reduce these effects by optimizing rotor speeds and blade angles. (Image: Vattenfall)

Machine learning helps make complex systems more efficient. Regardless of whether the systems in question are steel mills or gas turbines, they can learn from collected data, detect regular patterns, and optimize their own operations. Researchers at Siemens are demonstrating that continuous learning also allows wind turbines to increase their electricity output.

In his free time Volkmar Sterzing likes to work as a sailing instructor on Lake Starnberg south of Munich. A specialist in machine learning at Siemens Corporate Technology, Sterzing says that: “There are definitely parallels between sailing instruction and the machine learning process we use to optimize products.” Whereas his pupils learn to understand the power of the wind and to intuitively know when and how they have to set their sails, Sterzing studies how complex systems such as wind turbines can independently recognize regular patterns in collected data and thus learn how to optimize their operations.

Math Trick – Multiply Using Lines!

World’s first software to automate production-line image recognition

Figure 1: The conventional process of developing and revising an image-recognition program used with a camera in automated assembly equipment

Fujitsu Laboratories has announced the development of a technology for automatically generating image-recognition programs that accurately detect the positions of components as captured by cameras in automated assembly processes by utilizing images of electronic components and IT equipment. Automatically generated image-processing programs that use machine learning have not been able to detect positions up until now, requiring that experts individually develop image-recognition programs. As a result, any changes to the manufacturing setup, such as a machine’s operating parameters, could involve more than a week’s time spent revising the program, during which time the production line would sit idle. What Fujitsu Laboratories has done is to develop a technique for automatically generating image-processing programs that detect positions by controlling the order in which the various image-processing functions that make up a program are combined, and using machine learning based on the similarity of shapes. Samples of the object to be detected are presented as teaching materials, and this makes it possible to automatically generate an image-recognition program in roughly eight hours, or one-tenth the time previously required. Fujitsu Laboratories plans to use this technology to help make production lines better able to respond to changes in their operating environment without long downtime.

Details of this technology are being presented at the Autumn Meeting of the Japan Society for Precision Engineering, opening September 16 in Tottori, Japan. Read more of this post
