Machines v. hackers: Cybersecurity’s artificial intelligence future
|
Christian Science Monitor, CSMonitor.com
from July 25, 2016
It’s a common refrain after any recent high-profile breach into federal computers and corporate networks: There aren’t enough skilled cybersecurity professionals to outwit criminal hackers.
That message from officials, executives, and industry experts isn’t just grousing, either. According to industry estimates, the US needs about 200,000 more workers to fill current cybersecurity roles. Globally, the gap is five times higher – an estimated 1 million workers.

How To Fool AI Into Seeing Something That Isn’t There
|
WIRED, Security
from July 29, 2016
Our machines are littered with security holes, because programmers are human. Humans make mistakes. In building the software that drives these computing systems, they allow code to run in the wrong place. They let the wrong data into the right place. They let in too much data. All this opens doors through which hackers can attack, and they do.
But even when artificial intelligence supplants those human programmers, risks remain. AI makes mistakes, too. As described in a new paper from researchers at Google and OpenAI, the artificial intelligence startup recently bootstrapped by Tesla founder Elon Musk, these risks are apparent in the new breed of AI that is rapidly reinventing our computing systems, and they could be particularly problematic as AI moves into security cameras, sensors, and other devices spread across the physical world. “This is really something that everyone should be thinking about,” says OpenAI researcher and ex-Googler Ian Goodfellow, who wrote the paper alongside current Google researchers Alexey Kurakin and Samy Bengio.

The Double Game of Digital Management: Managing in Times of Big Data and Analytics
|
bcg.perspectives
from July 27, 2016
Digital technologies are profoundly transforming not just products, services, and business processes but also management itself and the inner workings of companies. A new generation of executives is relying on data analytics and artificial intelligence to support and make decisions.
Our aim is to demystify these once-arcane fields and show how they have moved out of the laboratory and into the executive suite.

How a happy moment for neuroscience is a sad moment for science
|
Medium, Mark Humphries
from August 01, 2016
The Allen Institute for Brain Science released a landmark set of data in June. Entitled the “Allen Brain Observatory”, it contains a vast array of recordings from the bit of cortex that deals with vision, while the eyes attached to that bit of cortex were looking at patterns. Not too exciting, you say. In some respects you’d be right: some mouse brain cells became active when shown some frankly boring pictures. Experimental neuroscience is eternally lucky that mice have a very high boredom threshold.
The release of this data took a privately funded institute. It could not have come from a publicly-funded scientist. It is a striking case-study in how modern science is worryingly broken, because it prioritises private achievement over the public good.

[1607.08237] The population of long-period transiting exoplanets
|
arXiv, Astrophysics > Earth and Planetary Astrophysics; Daniel Foreman-Mackey, Timothy D. Morton, David W. Hogg, Eric Agol, Bernhard Schölkopf
from July 27, 2016
The Kepler Mission has discovered thousands of exoplanets and revolutionized our understanding of their population. This large, homogeneous catalog of discoveries has enabled rigorous studies of the occurrence rate of exoplanets and planetary systems as a function of their physical properties. … we perform a fully automated search for long-period exoplanets with only one or two transits in the archival Kepler light curves. When applied to the 40,000 brightest Sun-like target stars, this search produces 16 long-period exoplanet candidates. Of these candidates, 6 are novel discoveries and 5 are in systems with inner short-period transiting planets.
More exoplanets:

Make Algorithms Accountable
|
The New York Times, Julia Angwin
from August 01, 2016
Algorithms are ubiquitous in our lives. They map out the best route to our destination and help us find new music based on what we listen to now. But they are also being employed to inform fundamental decisions about our lives.
Companies use them to sort through stacks of résumés from job seekers. Credit agencies use them to determine our credit scores. And the criminal justice system is increasingly using algorithms to predict a defendant’s future criminality.
Those computer-generated criminal “risk scores” were at the center of a recent Wisconsin Supreme Court decision that set the first significant limits on the use of risk algorithms in sentencing.

[1607.08723] Cognitive Science in the era of Artificial Intelligence: A roadmap for reverse-engineering the infant language-learner
|
arXiv, Computer Science > Computation and Language; Emmanuel Dupoux
from July 29, 2016
During their first years of life, infants learn the language(s) of their environment at an amazing speed despite large cross cultural variations in amount and complexity of the available language input. Understanding this simple fact still escapes current cognitive and linguistic theories. Recently, spectacular progress in the engineering science, notably, machine learning and wearable technology, offer the promise of revolutionizing the study of cognitive development. Machine learning offers powerful learning algorithms that can achieve human-like performance on many linguistic tasks. Wearable sensors can capture vast amounts of data, which enable the reconstruction of the sensory experience of infants in their natural environment. The project of ‘reverse engineering’ language development, i.e., of building an effective system that mimics infant’s achievements appears therefore to be within reach.
Here, we analyze the conditions under which such a project can contribute to our scientific understanding of early language development. We argue that instead of defining a sub-problem or simplifying the data, computational models should address the full complexity of the learning situation, and take as input the raw sensory signals available to infants. This implies that (1) accessible but privacy-preserving repositories of home data be setup and widely shared, and (2) models be evaluated at different linguistic levels through a benchmark of psycholinguist tests that can be passed by machines and humans alike, (3) linguistically and psychologically plausible learning architectures be scaled up to real data using probabilistic/optimization principles from machine learning. We discuss the feasibility of this approach and present preliminary results.

Projected spread of Zika virus in the Americas | bioRxiv
|
bioRxiv; Alessandro Vespignani et al.
from July 28, 2016
We use a data-driven global stochastic epidemic model to project past and future spread of the Zika virus (ZIKV) in the Americas. The model has high spatial and temporal resolution, and integrates real-world demographic, human mobility, socioeconomic, temperature, and vector density data. We estimate that the first introduction of ZIKV to Brazil likely occurred between August 2013 and April 2014. We provide simulated epidemic profiles of incident ZIKV infections for several countries in the Americas through December 2016. The ZIKV epidemic is characterized by slow growth and high spatial and seasonal heterogeneity, attributable to the dynamics of the mosquito vector and to the characteristics and mobility of the human populations. We project the expected timing and number of cases of microcephaly assuming three levels of risk associated with ZIKV infection during the first trimester of pregnancy. Our approach represents an early modeling effort aimed at projecting the potential magnitude and timing of the ZIKV epidemic that might be refined as new and more accurate data from the region will be available.

Bayesian second law of thermodynamics
|
Physical Review E; Anthony Bartolotta, Sean M. Carroll, Stefan Leichenauer, and Jason Pollack
from August 01, 2016
We derive a generalization of the second law of thermodynamics that uses Bayesian updates to explicitly incorporate the effects of a measurement of a system at some point in its evolution. By allowing an experimenter’s knowledge to be updated by the measurement process, this formulation resolves a tension between the fact that the entropy of a statistical system can sometimes fluctuate downward and the information-theoretic idea that knowledge of a stochastically evolving system degrades over time. The Bayesian second law can be written as ?H(?m,?)+?Q?F|m?0, where ?H(?m,?) is the change in the cross entropy between the original phase-space probability distribution ? and the measurement-updated distribution ?m and ?Q?F|m is the expectation value of a generalized heat flow out of the system. We also derive refined versions of the second law that bound the entropy increase from below by a non-negative number, as well as Bayesian versions of integral fluctuation theorems. We demonstrate the formalism using simple analytical and numerical examples.
