On the Vulnerability of Capsule Networks to Adversarial Attacks

arXiv.org Machine Learning

This paper extensively evaluates the vulnerability of capsule networks to different adversarial attacks. Recent work suggests that these architectures are more robust towards adversarial attacks than other neural networks. However, our experiments show that capsule networks can be fooled as easily as convolutional neural networks.


There is no general AI: Why Turing machines cannot pass the Turing test

arXiv.org Artificial Intelligence

Since 1950, when Alan Turing proposed what has since come to be called the Turing test, the ability of a machine to pass this test has established itself as the primary hallmark of general AI. To pass the test, a machine would have to be able to engage in dialogue in such a way that a human interrogator could not distinguish its behaviour from that of a human being. AI researchers have attempted to build machines that could meet this requirement, but they have so far failed. To pass the test, a machine would have to meet two conditions: (i) react appropriately to the variance in human dialogue and (ii) display a human-like personality and intentions. We argue, first, that it is for mathematical reasons impossible to program a machine which can master the enormously complex and constantly evolving pattern of variance which human dialogues contain. And second, that we do not know how to make machines that possess personality and intentions of the sort we find in humans. Since a Turing machine cannot master human dialogue behaviour, we conclude that a Turing machine also cannot possess what is called ``general'' Artificial Intelligence. We do, however, acknowledge the potential of Turing machines to master dialogue behaviour in highly restricted contexts, where what is called ``narrow'' AI can still be of considerable utility.


Developing a NLP based PR platform for the Canadian Elections

#artificialintelligence

Elections are a vital part of democracy allowing people to vote for the candidate they think can best lead the country. A candidate's campaign aims to demonstrate to the public why they think they are the best choice. However, in this age of constant media coverage and digital communications, the candidate is scrutinized at every step. A single misquote or negative news about a candidate can be the difference between him winning or losing the election. It becomes crucial to have a public relations manager who can guide and direct the candidate's campaign by prioritizing specific campaign activities. One critical aspect of the PR manager's work is to understand the public perception of their candidate and improve public sentiment about the candidate.


What If Artificial Intelligence (AI) & Machine Learning (ML) Ruled the World?

#artificialintelligence

What if instead of political parties, presidents, prime ministers, kings, queens, armies, autocrats, and who knows what else, we turned everything over to expert systems? What if we engineered them to be faithful, for example, to one simple principle: "human beings regardless of age, gender, race, origin, religion, location, intelligence, income or wealth, should be treated equally, fairly and consistently"? Here's some dialogue โ€“ enabled by natural language processing (NLP) โ€“ with an expert system named "Decider" that operates from that single principle (you can imagine how it might behave if the principle was completely different โ€“ the opposite of equal and fair). The principle is supported by the data and probabilities the system collects and interprets. The "inferences" made by Decider are pre-programmed.


Artificial Intelligence And The End Of Government

#artificialintelligence

Even as artificial intelligence (AI) is forecast to exceed human capabilities across a range of industries it is also predicted to augment human labor. In finance, AI is already helping financial advisors augment financial planning while enhancing investment strategy. And in medicine, AI diagnostics systems have proven to be far more accurate than doctors in diagnosing heart disease and cancerous growths. In fact, McKinsey lists some 400 use cases representing $6 trillion in value across 19 industries in which AI will augment human work. What will the impact of AI be on the nature of government?


G20 ministers kick of talks on trade and the digital economy in Ibaraki Prefecture

The Japan Times

However, reaching consensus is likely to prove difficult on some key issues, in particular those involving trade. Participating nations have clashing interests, most notably the U.S. and China. "First, I would like to stress the importance of tapping into data, which is the source of innovation," Hiroshige Seko, minister of economy, trade and industry, said at the beginning of the digital economy session. Seko said that "ensuring the free flow of data internationally is indispensable to the economic development of the world as a whole." He then introduced a concept called "Data Fee Flow with Trust," or DFFT, which he said would promote free data flows while securing trust related to privacy and security.


Jeff Bezos says space exploration is needed to 'save the Earth'

Daily Mail - Science & tech

Jeff Bezos wants to colonize space in order to'save the Earth.' At Amazon's inaugural Re:MARS conference in Las Vegas, Bezos broke down how his rocket company, Blue Origin, could play a major role in the future of space exploration. Bezos recently unveiled Blue Origin's lunar lander, which is a key component of the company's plans to conduct space missions and explore the moon's surface. At Amazon's inaugural Re:MARS conference in Las Vegas, CEO Jeff Bezos broke down how his rocket company, Blue Origin, could play a major role in the future of space exploration The comments came during an interview with Jenny Freshwater, Amazon's director of forecasting. The interview was briefly disrupted by an animal rights protester, Priya Sawhney of Direct Action Everywhere, who grilled Bezos on the treatment of chickens at Amazon-affiliated farms, before being briskly whisked off stage.


Learning Radiative Transfer Models for Climate Change Applications in Imaging Spectroscopy

arXiv.org Machine Learning

According to a recent investigation, an estimated 33-50% of the world's coral reefs have undergone degradation, believed to be as a result of climate change. A strong driver of climate change and the subsequent environmental impact are greenhouse gases such as methane. However, the exact relation climate change has to the environmental condition cannot be easily established. Remote sensing methods are increasingly being used to quantify and draw connections between rapidly changing climatic conditions and environmental impact. A crucial part of this analysis is processing spectroscopy data using radiative transfer models (RTMs) which is a computationally expensive process and limits their use with high volume imaging spectrometers. This work presents an algorithm that can efficiently emulate RTMs using neural networks leading to a multifold speedup in processing time, and yielding multiple downstream benefits.


Guidelines for Responsible and Human-Centered Use of Explainable Machine Learning

arXiv.org Artificial Intelligence

Explainable machine learning (ML) has been implemented in numerous open source and proprietary software packages and explainable ML is an important aspect of commercial predictive modeling. However, explainable ML can be misused, particularly as a faulty safeguard for harmful black-boxes, e.g. fairwashing, and for other malevolent purposes like model stealing. This text discusses definitions, examples, and guidelines that promote a holistic and human-centered approach to ML which includes interpretable (i.e. white-box ) models and explanatory, debugging, and disparate impact analysis techniques.


Provably Robust Boosted Decision Stumps and Trees against Adversarial Attacks

arXiv.org Machine Learning

The problem of adversarial samples has been studied extensively for neural networks. However, for boosting, in particular boosted decision trees and decision stumps there are almost no results, even though boosted decision trees, as e.g. XGBoost, are quite popular due to their interpretability and good prediction performance. We show in this paper that for boosted decision stumps the exact min-max optimal robust loss and test error for an $l_\infty$-attack can be computed in $O(n\,T\log T)$, where $T$ is the number of decision stumps and $n$ the number of data points, as well as an optimal update of the ensemble in $O(n^2\,T\log T)$. While not exact, we show how to optimize an upper bound on the robust loss for boosted trees. Up to our knowledge, these are the first algorithms directly optimizing provable robustness guarantees in the area of boosting. We make the code of all our experiments publicly available at https://github.com/max-andr/provably-robust-boosting
