Turkey to be among pioneers of AI-controlled warplane: Erdoğan


Turkey aims to be among the first countries to have an entirely artificial intelligence (AI)-controlled unmanned warplane, with plans for it to take to the Turkish skies in 2023, President Recep Tayyip Erdoğan said Wednesday. The success of Turkish unmanned aerial vehicles (UAV) in the field has produced results that "require war strategies to be rewritten," the president said. Erdoğan was speaking at the ruling Justice and Development Party's (AK Party) parliamentary group meeting in the capital Ankara. The president added that currently a total of 180 Bayraktar TB2 unmanned combat aerial vehicles (UCAVs) are operated in four countries, including Turkey. Previously, Turkish drone magnate Baykar's Chief Technology Officer Selçuk Bayraktar said the maiden flight of the prototype of the country's domestically-made unmanned fighter jet is scheduled for 2023.

Alternating Between Spectral and Spatial Estimation for Speech Separation and Enhancement Machine Learning

This work investigates alternation between spectral separation using masking-based networks and spatial separation using multichannel beamforming. In this framework, the spectral separation is performed using a mask-based deep network. The result of mask-based separation is used, in turn, to estimate a spatial beamformer. The output of the beamformer is fed back into another mask-based separation network. We explore multiple ways of computing time-varying covariance matrices to improve beamforming, including factorizing the spatial covariance into a time-varying amplitude component and time-invariant spatial component. For the subsequent mask-based filtering, we consider different modes, including masking the noisy input, masking the beamformer output, and a hybrid approach combining both. Our best method first uses spectral separation, then spatial beamforming, and finally a spectral post-filter, and demonstrates an average improvement of 2.8 dB over baseline mask-based separation, across four different reverberant speech enhancement and separation tasks.

Feds Give Kaspersky Security Products the Boot, and Other Security News This Week


Apple finally announced the iPhone X this week, complete with a facial recognition system that Apple calls FaceID. Preliminary impressions are that FaceID will be difficult to trick, and should be secure for the average user, but researchers are eager to test its robustness. Apple's new iOS 11 mobile operating system does have more crucial privacy protections against muggers and government officials alike but researchers detailed doubts this week about the "differential privacy" techniques Apple uses that are meant to aggregate and analyze customer data without invading their privacy. In other words, Equifax could have prevented the breach by patching the bug. US residents rushed to find ways to protect themselves against potential identity theft, while officials scrambled to determine possible recourse against Equifax and looked for ways to prevent similar crises in the future.

WASHINGTON (AP) -- Michael Flynn, the former Army lieutenant general Donald Trump has asked to be his national security adviser, rose through the ranks of military intelligence on the strength of his reputation as an astute professional and an unconventional thinker.
