    Sometimes algorithm matter a lot
    • Computational costs become a limiting factor when dealing with big systems. The exponential growth in the hardware performance observed over the past 60 years (the Moore’s law) is expected to end in the early 2020s. More advanced machine learning approaches (e.g., NNs) exhibit the cost scaling that grows polynomial with the dimension and the size of the statistics, rendering some form of ad hoc preprocessing and prereduction with more simple approaches (e.g., clustering methods) unavoidable for big data situations. However, these ad hoc preprocessing steps might impose a strong bias that is not easy to quantify. At the same time, lower cost of the method typically goes hand-in-hand with the lower quality of the obtained data representations (see Fig. 1). Since the amounts of collected data in most of the natural sciences are expected to continue their exponential growth in the near future, pressure on computational performance (quality) and scaling (cost) of algorithms will increase.

      Instead of solving discretization, feature selection, and prediction problems separately, the introduced computational procedure (SPA) solves them simultaneously. The iteration complexity of SPA scales linearly with data size. The amount of communication between processors in the parallel implementation is independent of the data size and linear with the data dimension (Fig. 2), making it appropriate for big data applications. Hence, SPA did not require any form of data prereduction for any of the considered applications. As shown in the Fig. 1, having essentially the same iteration cost scaling as the very popular and computationally very cheap K-means algorithm (16, 17), SPA allows achieving substantially higher approximation quality and a much higher parallel speedup with the growing size T of the data.

    3D imaging with material classification
    • trinamiX GmbH, a leader in 3D imaging and infrared sensing technologies, today announced it has joined the Qualcomm Software Accelerator Program to enable its patented technology for "live skin" detection as the new gold-standard for facial recognition across mobile devices.

      Through this new collaboration with trinamiX and Qualcomm Technologies, OEM customers will now be able to use the trinamiX proprietary "Beam Profile Analysis" technology, which extracts 3 data streams from a single camera system: a 2D IR image, a 3D depth map and most uniquely – material classification.

      Using this fundamentally new approach to security, it is now possible to combine standard facial-recognition algorithms from any 3rd party with the unique ability to sense "live skin." This eliminates the ability to fool the phone into unlocking via a mask, a high-resolution print or even a 3D rendering of the rightful owner's facial features. trinamiX patented technology enables an industry-leading, secure and robust facial recognition solution for devices ranging from smartphones to laptops and up to securing access control systems.

      The material classification is accomplished through trinamiX proprietary algorithms that run on the Qualcomm® Hexagon™ Processor on Qualcomm® Snapdragon™ mobile platforms.

      This ability to classify and identify materials based on their physical properties is a result of trinamiX research and development while operating as a wholly owned subsidiary of BASF SE, the world's leading chemical company. trinamiX is operationally independent while at the same time also having unique and unprecedented access to the expertise and experience of the entire BASF Group.

      "Qualcomm Technologies has always differentiated its product line through a unique blend of raw performance combined with industry-leading features demanded by the most innovative mobile device OEMs," said Manvinder Singh, Vice President, Product Management, Qualcomm Technologies, Inc. "We are very excited to be working with trinamiX and look forward to trinamiX getting this novel technology into the hands of customers at the earliest possible opportunity."

      "trinamiX has distinguished itself by providing the world's most innovative 3D imaging solution using our Beam Profile Analysis technology, and we are thrilled to be working with Qualcomm Technologies, the world's leading wireless technology innovator," said Dr. Ingmar Bruder, Managing Director and founder of trinamiX. "Using our patented 3D imaging technology, the solution will enable mobile devices powered by the Hexagon Processor inside Snapdragon mobile platforms to achieve a previously unattainable goal – the ability to sense live skin as part of a secure facial recognition."

    Capitalism: Bed bugs now join coronavirus
    • After disappearing from France in the 1950s, the insects have made a resurgence, according to the ministry of housing, which cited international travel and growing resistance to insecticide as the main causes.

      I think it is growing capitalism around that brought his old friends back.

    Capitalism: Mordor blocks lot of email services
    • In last month blocked

      • Protonmail
      • Mailbox.org
      • Scryptmail.com
      • Tutanota
      • Startmail

      Tech was simple - first use them to send lot of email about bombs to themselves, next silently block.

      Access to sites blocked, and all internal big domains and major email providers started rejecting any email from them.

    Idiots news galore: Sony fake blame and DRAM shortage
    • “Sony has already canceled some previously planned features for a new mirrorless camera due this year owing to the constrained DRAM supply, several people with knowledge of the matter said.” – Japan Times

      This is being republished over and over.

      Actually it could not get any official credible source (just rumor words) and SOLE purpose of this is that Sony now wants to find foundation for their high Playstation 5 price. And it can't. As coronavirus broke all their plans (much smaller demand for NAND and DRAM now).

      So NAND and DRAM manufacturers cartels had been not prepared and prices for chips did not rebound as they planned.

      Sony secured NAND and DRAM for special very nice private prices (around 30% below lower point on the market) and wanted to get nice big profits from PS5 from the start. But now try to postpone price announcements as it'll look silly.

    Capitalism: HSBC cutting 35000 jobs
    • HSBC has announced it will axe 35,000 jobs worldwide as part of a major restructuring after the bank’s profits fell by a third last year.

      The bank is aiming to scale back its headcount from 235,000 to 200,000 over the next three years as it attempts to cut £3.5bn in costs by 2022 and shed more than £70bn of assets.

      And it is only small start.

    China: Zugzwang
    • As it is now clear - decision to make total lockdown and quarantine 500 million of citizens had been wrong.

      Issue is that big and nice looking bureaucratic machine wanted to repeat that worked with SARS and previous cases.

      But they faced "small" issues - they started to do it too late (had been very afraid of huge protest movement if they won't let people go home on Chinese New Year) and infection is very different as it has asymptomatic stage where owner already spreads the virus. So all this temperature checks do mostly nothing.

      You can observe how very strict lockdown and quarantine works on cruise ship docked in Japanese. Small tip - it works horribly. Everything that can go wrong goes wrong (but with previous cases of viruses same things worked).

      Now it is time to make next move, and in modern China it means to start full fledged work almost eliminating any protections. And this can lead to coup, right (becoming total US protectorate) or left (throwing out opportunists and rely on people, making second Cultural Revolution).

      Btw, China also has no masks for everyone for each day to even start working. And it is big idiotic secret of government.
