Is Artificial Intelligence (AI) A Threat To Humans?
Are artificial intelligence (AI) and superintelligent machines the best or worst thing that could ever happen to humankind? This has been a question in existence since the 1940s when computer scientist Alan Turing wondered and began to believe that there would be a time when machines could have an unlimited impact on humanity through a process that mimicked evolution. Is Artificial Intelligence (AI) A Threat To Humans? When Oxford University Professor Nick Bostrom's New York Times best-seller, Superintelligence: Paths, Dangers, Strategies was first published in 2014, it struck a nerve at the heart of this debate with its focus on all the things that could go wrong. However, in my recent conversation with Bostrom, he also acknowledged there's an enormous upside to artificial intelligence technology.
AI Bias Could Put Women's Lives At Risk - A Challenge For Regulators
When the European Commission released the long awaited white paper "On Artificial Intelligence - A European approach to excellence and trust" on February 19, much of the initial public reaction focused on potential AI regulation further challenging the EU's position in light of fierce technological competition from China and the United States. Few discussed the European Commission's document mention of gender and ethical guidelines. Importantly, the white paper calls for "requirements to take reasonable measures aimed at ensuring that [the] use of AI systems does not lead to outcomes entailing prohibited discrimination." This is not simply about a theoretical approach to discrimination. It is largely also about saving (women's) lives - and ensuring that essential products and services meet the needs of both women and men.
How To Combat The Dark Side Of AI
Imagine being thrown into a morning panic by the sound of a blaring alarm, screaming at you to take immediate shelter. Your Smart TV displays the words "AERIAL DRONE RAID" in all red, and as you attempt to rationalize what is going on, you inch towards the window in sheer disbelief as you discover a decimated cityscape. Rogue armies of drone wasps run amok in search of deviants to poison and kill, unmanned tanks obliterate anything moving on the streets and sophisticated digital twin satellites successfully cripple our electric power grid system with advanced EMP attacks. Cyber criminals have already taken advantage of the situation, broadcasting "deep fake" news of a deadly virus to cause panic and hysteria among the masses. Biohackers take it a step further, threatening to unleash an AI-manufactured strain of the flu unless the government provides them with a sizable paycheck.
EU launches plan to regulate A.I., taking aim at Silicon Valley giants
One area that the Commission is particularly concerned about is facial recognition. At the moment, the processing of biometric data in order to identify people is illegal in most cases, under data privacy laws. However, the EU is now looking at whether there should be certain exceptions. Speaking to journalists in Brussels, Margrethe Vestager, the EU's head of competition policy, said: "Artificial intelligence is not good or bad in itself, it all depends on why and how it is used." In an exclusive interview with CNBC Tuesday, Vestager said that the EU is taking a "double-sided" approach where it will enable this technology, while also ensuring it's not harmful to EU citizens.
How a Portland nonprofit is using artificial intelligence to help save whales, giraffes, zebras
To the untrained eye, zebras in Kenya probably all look alike. But each animal's black and white markings are like a fingerprint, distinct -- and invaluable for scientists who need to track the animals and information about them, including their births, deaths, health and migration patterns. Traditionally, getting this kind of information has been an invasive and labor-intensive process. But breakthroughs in artificial intelligence (AI) and crowdsourcing of photos of individual animals are beginning to change the conservation game. Portland, Oregon-based nonprofit Wild Me has developed AI to pick out identifying markers -- the stripes on a zebra, the spots on a giraffe, the contours of a flukewhale's fin -- and catalog animals much faster than a human can.
America Must Shape the World's AI Norms -- or Dictators Will
As Secretaries of Defense, we anticipated and addressed threats to our nation, sought strategic opportunities, exercised authority, direction, and control over the U.S. military, and executed many other tasks in order to protect the American people and our way of life. During our combined service leading the Department of Defense, we navigated historical inflection points – the end of the Cold War and its aftermath, the War on Terror, and the reemergence of great power competition. Now, based on our collective experience, we believe the development and application of artificial intelligence and machine learning will dramatically affect every part of the Department of Defense, and will play as prominent a role in our country's future as the many strategic shifts we witnessed while in office. The digital revolution is changing our society at an unprecedented rate. Nearly 60 years passed between the construction of the first railroads in the United States and the completion of the First Transcontinental Railroad.
Bayesian Neural Networks With Maximum Mean Discrepancy Regularization
Pomponi, Jary, Scardapane, Simone, Uncini, Aurelio
Bayesian Neural Networks (BNNs) are trained to optimize an entire distribution over their weights instead of a single set, having significant advantages in terms of, e.g., interpretability, multi-task learning, and calibration. Because of the intractability of the resulting optimization problem, most BNNs are either sampled through Monte Carlo methods, or trained by minimizing a suitable Evidence Lower BOund (ELBO) on a variational approximation. In this paper, we propose a variant of the latter, wherein we replace the Kullback-Leibler divergence in the ELBO term with a Maximum Mean Discrepancy (MMD) estimator, inspired by recent work in variational inference. After motivating our proposal based on the properties of the MMD term, we proceed to show a number of empirical advantages of the proposed formulation over the state-of-the-art. In particular, our BNNs achieve higher accuracy on multiple benchmarks, including several image classification tasks. In addition, they are more robust to the selection of a prior over the weights, and they are better calibrated. As a second contribution, we provide a new formulation for estimating the uncertainty on a given prediction, showing it performs in a more robust fashion against adversarial attacks and the injection of noise over their inputs, compared to more classical criteria such as the differential entropy.
Structured Prediction with Partial Labelling through the Infimum Loss
Cabannes, Vivien, Rudi, Alessandro, Bach, Francis
Fully supervised learning demands tight supervision of large amounts of data, a supervision that can be quite costly to acquire and constrains the scope of applications. To overcome this bottleneck, the machine learning community is seeking to incorporate weaker sources of information in the learning framework. In this paper, we address those limitations through partial labelling: e.g., giving only partial ordering when learning user preferences over items, or providing the label "flower" for a picture of Arum Lilies 1, instead of spending a consequent amount of time to find the exact taxonomy. Partial labelling has been studied in the context of classification Cour et al. (2011); Nguyen and Caruana (2008), multilabelling Yu et al. (2014), ranking Hüllermeier et al. (2008); Korba et al. (2018), as well as segmentation Verbeek and Triggs (2008); Papandreou et al. (2015), however a generic framework is still missing. Such a framework is a crucial step towards understanding how to learn from weaker sources of information, and widening the spectrum of machine learning beyond rigid applications of supervised learning. Some interesting directions are provided by Cid-Sueiro et al. (2014); van Rooyen and Williamson (2017), to recover the information lost in a corrupt acquisition of labels. Yet, they assume that the corruption process is known, which is a strong requirement that we want to relax. In this paper, we make the following contributions: - We provide a principled framework to solve the problem of learning with partial labelling, via structured prediction. This approach naturally leads to a variational framework built on the infimum loss.
Is Machine Learning Always The Right Choice? - Machine Learning Times - machine learning & data science news
Since this article will probably come out during Income tax season, let me start with the following example: Suppose we would like to build a program that calculates income tax for people. According to US federal income tax rules: "For single filers, all income less than $9,875 is subject to a 10% tax rate. Therefore, if you have $9,900 in taxable income, the first $9,875 is subject to the 10% rate and the remaining $25 is subject to the tax rate of the next bracket (12%)". This is an example of rules or an algorithm (set of instructions) for a computer. Let's look at this from a formal, pragmatic point of view. A computer equipped with this program can achieve the goal (calculate tax) without human help.
