Privacy-aware Early Detection of COVID-19 through Adversarial Training

arXiv.org Artificial Intelligence

Early detection of COVID-19 is an ongoing area of research that can help with triage, monitoring and general health assessment of potential patients and may reduce operational strain on hospitals that cope with the coronavirus pandemic. Different machine learning techniques have been used in the literature to detect coronavirus using routine clinical data (blood tests, and vital signs). Data breaches and information leakage when using these models can bring reputational damage and cause legal issues for hospitals. In spite of this, protecting healthcare models against leakage of potentially sensitive information is an understudied research area. In this work, we examine two machine learning approaches, intended to predict a patient's COVID-19 status using routinely collected and readily available clinical data. We employ adversarial training to explore robust deep learning architectures that protect attributes related to demographic information about the patients. The two models we examine in this work are intended to preserve sensitive information against adversarial attacks and information leakage. In a series of experiments using datasets from the Oxford University Hospitals, Bedfordshire Hospitals NHS Foundation Trust, University Hospitals Birmingham NHS Foundation Trust, and Portsmouth Hospitals University NHS Trust we train and test two neural networks that predict PCR test results using information from basic laboratory blood tests, and vital signs performed on a patients' arrival to hospital. We assess the level of privacy each one of the models can provide and show the efficacy and robustness of our proposed architectures against a comparable baseline. One of our main contributions is that we specifically target the development of effective COVID-19 detection models with built-in mechanisms in order to selectively protect sensitive attributes against adversarial attacks.


Federated Deep Learning in Electricity Forecasting: An MCDM Approach

arXiv.org Artificial Intelligence

It is well know that Artificial Intelligence (AI) identifies in a broad sense the ability of a machine to learn from experience, to simulate the human intelligence, to adapt to new scenarios, and to get engaged in human-like activities. AI identifies an interdisciplinary area which includes computer science, robotics, engineering, mathematics. Over the years, it has made a rapid progress: it will contribute to the society transformation through the adoption of innovating technologies and creative intelligence and the large-scale implementation of AI in technologies such as IoT, smart speakers, chat-bots, cybersecurity, 3D printing, drones, face emotions analysis, sentiment analysis, natural language processing, and their applications to human resources, marketing, finance, and many others. With the term Machine learning (ML), instead, we identify a branch of AI in which algorithms are used to learn from data to make future decisions or predictions. ML algorithms are trained on past data in order to make future predictions or to support the decision making process. Deep Learning (DL), instead, is a subset of ML and it includes a large family of ML methods and architectures based on Artificial Neural Networks (ANNs). It includes Deep Neural Networks, Deep Belief Networks, Deep Reinforcement Learning, Recurrent Neural Networks and Convolutional Neural Networks, to mention a few of them. DL algorithms have been used in several applications including computer vision, speech recognition, natural language processing, bioinformatics, medical image analysis, and in most of these areas they have demonstrated to perform better than humans. In the recent years DL has disrupted every application domain and it provides a robust, generalized, and scalable approach to work with different data types, including time-series data [1-4].


7 ways the technology sector could support global society in 2022 - JackOfAllTechs.com

#artificialintelligence

Some of the excesses of 2021 have shown us how digital technologies can undermine what philosophers call future "human flourishing." A lot has been written on this topic in the first few days of the new year, but take two examples -- MIT Technology Review's list of the worst excesses of technology and Fast Company's 5 best and worst tech moments of 2021 -- and it's evident how little power people affected by technologies have when things go wrong under current systems. What's also clear as we enter 2022 is that global tolerance for technology's unchecked disruption of societal institutions, conventions, and values is waning. This is the year governments will pass legislation to control the effects of digital technologies on societies, across many jurisdictions and in relation to numerous existing and emergent technologies. The EU AI and Digital Services Acts, the UK Online Safety Bill, and the US SAFE TECH Act are just a few of the efforts underway. Legislation is a marker of societal concern, but it's also clear that non-specialist, "ordinary" people have an increasingly sophisticated understanding of the relationship between technology and society.

Artificial intelligence is the backbone of a myriad of innovations in today's world such as self-driving cars, high-tech computing, enterprise solutions, and robotics to name a few. AI is also set to play a key role in blockchain technology which forms the basis of the cryptocurrency industry. In addition, AI also played a key role in fighting the spread of COVID-19 from contact tracing to robots and drone deployment to responding to urgent needs in hospitals as well as performing deliveries of food, medications, and equipment.


Employers, Investors Take Notice of AI Tools to Speed Job Recruitment

#artificialintelligence

Artificial-intelligence capabilities, like conversational AI software, can speed up the early back-and-forth emails, texts and other communications with applicants and quickly get strong candidates in front of recruiters. Other AI-enabled tools are being used to accelerate the employee onboarding process, getting new hires oriented, trained and set up with computers, business apps and corporate email accounts. The Morning Download delivers daily insights and news on business technology from the CIO Journal team. Trucking company U.S. Xpress Enterprises Inc. uses conversational AI software to handle most of the early stages of the hiring process, including text exchanges with job applicants, said Amanda Thompson, the Chattanooga, Tenn.-based business's chief people officer. When job seekers submit an application via a mobile device, the AI tool automatically replies with a series of preliminary questions, she said.


Mars Perseverance halts rock sample storage due to debris

Engadget

The Mars Perseverance rover's sample collection has run into a snag. NASA reports the rover stopped caching samples after debris partly blocked the bit carousel (the device that stores drill bits and passes sample tubes for internal processing). The rover encountered the anomaly on December 29th, but the mission team had to wait until January 6th to send a command to extract the drill bit, undock the robot arm from the carousel and take images to verify what happened. The obstacles are believed to be pebbles that fell out of the sample tube when dropping off the coring bit, preventing that bit from sitting neatly in the carousel. The storage is crucial for NASA's plans to eventually return the samples to Earth.


After decades of planning, NASA's $10 billion space telescope has 'taken its final form'

USATODAY - Tech Top Stories

All systems are go for NASA's James Webb Space Telescope, which deployed its full gold-plated, sunflower-shaped mirror display Saturday. Now, the $10 billion successor to the Hubble telescope has five months of alignment and calibration procedures before it is expected to start sending images back to Earth, the space agency said Saturday. "Two weeks after launch, @NASAWebb has hit its next biggest milestone: the mirrors have completed deployment and the next-generation telescope has taken its final form," NASA announced Saturday. The news marked the completion of a "remarkable feat," said Gregory Robinson, NASA's Webb program director, in a statement. "The successful completion of all of the Webb Space Telescope's deployments is historic," he said.


AI is quietly eating up the world's workforce with job automation

#artificialintelligence

This article was contributed by Valerias Bangert, strategy and innovation consultant, founder of three media outlets, and published author. The debate around whether AI will automate jobs away is heating up. AI critics claim that these statistical models lack the creativity and intuition of human workers and that they are thus doomed to specific, repetitive tasks. While AI job automation has already replaced around 400,000 factory jobs in the U.S. from 1990 to 2007, with another 2 million on the way, AI today is automating the economy in a much more subtle way. Take the example of writing jobs.


AI Weekly: The implications of self-driving tractors and coming AI regulations

#artificialintelligence

It's 2022, and developments in the AI industry are off to a slow -- but nonetheless eventful -- start. While the spread of the Omicron variant put a damper on in-person conferences, enterprises aren't letting the pandemic disrupt the course of technological progress. John Deere previewed a tractor that uses AI to find a way to a field on its own and plow the soil without instructions. As Wired's Will Knight point outs, it and -- self-driving tractors like it -- could help to address the growing labor shortage in agriculture; employment of agriculture workers is expected to increase just 1% from 2019 to 2029. But they also raise questions about vendor lock-in and the role of human farmers alongside robots.


Fear of angering Trump prompted Japan about-face on U.S. drone purchase

The Japan Times

Japan overturned in 2020 its decision to cancel acquisition of U.S.-made reconnaissance drones due to their massive costs out of consideration to then-U.S. President Donald Trump, who was promoting American weapons exports, according to sources close to the matter. The government of then-Prime Minister Shinzo Abe had told Washington in the spring of 2020 that it would not purchase the Global Hawk drones, but reversed the decision in the summer after Tokyo scrapped in June that year its planned deployment of U.S.-developed land-based Aegis Ashore ballistic missile defense systems, they said. The about-face was prompted by concerns that cancellation of the Global Hawk acquisition would "anger Mr. Trump, who has insisted on exporting U.S.-made weapons," according to a source familiar with the matter. The policy change reflected "excessive consideration for Mr. Trump," the source said.
