Tolerating Adversarial Attacks and Byzantine Faults in Distributed Machine Learning

#artificialintelligence

To tolerate the outliers, robust statistics have been proposed. We summarize them in Table I. Yin et al. [36] proposed Median 111In the paper, we define the uppercase Median as a GAR solution and the lowercase median as the middle value. However, a recent paper proved that the Median aggregation rule is still under an order-optimal error rate [15]. Blanchard et al. [5] proposed Krum for selecting a valid vector update.


Japan Pavilion at Dubai Expo to offer online virtual tours

The Japan Times

The Japan Pavilion at the world exposition to be held in Dubai from next month is set to use digital technology to give people from around the world a virtual tour of the exhibit. The pavilion will convey the attractiveness of Japan to visitors from all over the world by allowing them to experience the country's history and technology, the Ministry of Economy, Trade and Industry said, as Japan hopes to boost excitement for the 2025 World Expo in Osaka. In addition to opening two special websites to serve as a "Virtual Japan Pavilion," the country will allow people to use remotely controlled avatar robots to participate in some events at the pavilion. Those events will be held for a limited number of participants for a limited period of time. Under the theme of "Where Ideas Meet," the Japan Pavilion will use the latest visual and spatial presentations, including moving images and ultrafine mist, to let visitors experience how diverse encounters spark new ideas and lead the world to a better tomorrow, according to the ministry. The exhibitions will highlight Japan's landscape and the challenges the world faces now.


Council Post: Is Your AI Ethical? Three Ways To Bake Impact Into Your Business Model

#artificialintelligence

Wendy Gonzalez is the CEO of Sama, the provider of accurate data for ambitious AI. We've all seen the headlines on the rapid adoption of artificial intelligence (AI) across industries. From improved efficiencies in inventory management to new capabilities in vaccine development, AI has the power to revolutionize the way we work, interact and are entertained. Less commonly discussed, however, is the importance of implementing an ethical AI supply chain. Much like other large industries, AI can run into trouble when produced at scale.


Ethics of AI: A Systematic Literature Review of Principles and Challenges

arXiv.org Artificial Intelligence

Ethics in AI becomes a global topic of interest for both policymakers and academic researchers. In the last few years, various research organizations, lawyers, think tankers and regulatory bodies get involved in developing AI ethics guidelines and principles. However, there is still debate about the implications of these principles. We conducted a systematic literature review (SLR) study to investigate the agreement on the significance of AI principles and identify the challenging factors that could negatively impact the adoption of AI ethics principles. The results reveal that the global convergence set consists of 22 ethical principles and 15 challenges. Transparency, privacy, accountability and fairness are identified as the most common AI ethics principles. Similarly, lack of ethical knowledge and vague principles are reported as the significant challenges for considering ethics in AI. The findings of this study are the preliminary inputs for proposing a maturity model that assess the ethical capabilities of AI systems and provide best practices for further improvements.


Kernel PCA with the Nystr\"om method

arXiv.org Machine Learning

Kernel methods generalize classical statistical methods to discover non-linear patterns in data [Shawe-Taylor and Cristianini, 2004]. They have been demonstrated to achieve state-of-the-art results in many application domains and it is straightforward to apply them to non-numeric data, such as graphs or text [Vishwanathan et al., 2010, Lodhi et al., 2002]. Through a near arbitrary non-linear mapping of data points into a Hilbert space they offer remarkable flexibility whilst providing a precise mathematical framework for statistical analyses. A host of linear statistical methods have been adapted to be used with kernels, including Fisher discriminant analysis (FDA) [Mika et al., 1999], independent component analysis (ICA) [Bach and Jordan, 2002], instrumental variable (IV) regression [Singh et al., 2019], and many more. Kernel PCA is a non-linear version of principal component analysis (PCA), a ubiquitous method to discover the most important directions of variation in data [Pearson, 1901]. PCA may be used for dimensionality reduction, exploratory data analysis, anomaly detection, discriminant analysis, clustering, or as a general preprocessing step for regression or classification [Jolliffe, 2002, Wold et al., 1987]. The other side of the coin of kernel methods is their large computational requirements, as they generally scale in the number of data points rather than the number of data dimensions. As a remedy, various approximations have been proposed, such as the Nystrรถm method, which randomly selects a smaller subset of data points and looks for solutions in their linear span. The Nystrรถm method also plays an important role in recent state-of-the-art implementations of kernel methods [Rudi et al., 2017, Ma and Belkin, 2017, Meanti et al., 2020].


Estimating a new panel MSK dataset for comparative analyses of national absorptive capacity systems, economic growth, and development in low and middle income economies

arXiv.org Machine Learning

Within the national innovation system literature, empirical analyses are severely lacking for developing economies. Particularly, the low- and middle-income countries (LMICs) eligible for the World Bank's International Development Association (IDA) support, are rarely part of any empirical discourse on growth, development, and innovation. One major issue hindering panel analyses in LMICs, and thus them being subject to any empirical discussion, is the lack of complete data availability. This work offers a new complete panel dataset with no missing values for LMICs eligible for IDA's support. I use a standard, widely respected multiple imputation technique (specifically, Predictive Mean Matching) developed by Rubin (1987). This technique respects the structure of multivariate continuous panel data at the country level. I employ this technique to create a large dataset consisting of many variables drawn from publicly available established sources. These variables, in turn, capture six crucial country-level capacities: technological capacity, financial capacity, human capital capacity, infrastructural capacity, public policy capacity, and social capacity. Such capacities are part and parcel of the National Absorptive Capacity Systems (NACS). The dataset (MSK dataset) thus produced contains data on 47 variables for 82 LMICs between 2005 and 2019. The dataset has passed a quality and reliability check and can thus be used for comparative analyses of national absorptive capacities and development, transition, and convergence analyses among LMICs.


Last U.S. Drone Strike in Kabul Reportedly Targeted Aid Worker Who Didn't Have Explosives

Slate

U.S. officials called it a "righteous strike." It was the last drone strike before the U.S. troop withdrawal from Afghanistan and American officials claimed they stopped an ISIS bomb that posed an imminent threat to the Kabul airport. Turns out though that the strike appears to have killed a worker for a U.S. aid group and there are indications there were no explosives in the vehicle that was hit, according to investigations by the New York Times and Washington Post. In all, 10 civilians appeared to have been killed in the Aug. 29 strike, including seven children. They were all members of the same extended family.


Best tasks humans have offloaded to robotic helpers

#artificialintelligence

Robonaut2 positioned next to an astronaut spacesuit. Robots were once reserved for the pages of paperback pulp, but in recent decades, these bots have transformed from science fiction to everyday reality. Robotic interactions are a common part of the modern human experience as these increasingly nimble machines are designed with new skills and dexterity. During this time, robots have augmented human roles across industries from manufacturing to space exploration. From autonomous pizza delivery and bionic bartending to sports entertainment, here are some of the top tasks humans have offloaded onto our robotic assistants.


Predicting New York's Hospital Costs

#artificialintelligence

In 2019, Donald Trump signed an executive order ordering hospitals to make the costs of common medical services publicly available. Yet, as of March 2021, many hospitals have been non compliant, making it difficult for patients to properly consider the effect of health services on their finances. This article details my creation of a ML XGBoost model to supplement the efforts of the executive order, as well as unexpected findings. Using user-entered values for Length of Stay, Disease Severity, and other variables, the model is capable of predicting hospital charges for three common infections: pneumonia, septicemia, and skin infections/cellulitis. The model is currently only applicable to New York State.
