NLS: an accurate and yet easy-to-interpret regression method

arXiv.org Machine Learning

An important feature of successful supervised machine learning applications is to be able to explain the predictions given by the regression or classification model being used. However, most state-of-the-art models that have good predictive power lead to predictions that are hard to interpret. Thus, several model-agnostic interpreters have been developed recently as a way of explaining black-box classifiers. In practice, using these methods is a slow process because a novel fitting is required for each new testing instance, and several non-trivial choices must be made. We develop NLS (neural local smoother), a method that is complex enough to give good predictions, and yet gives solutions that are easy to be interpreted without the need of using a separate interpreter. The key idea is to use a neural network that imposes a local linear shape to the output layer. We show that NLS leads to predictive power that is comparable to state-of-the-art machine learning models, and yet is easier to interpret.


A Nonparametric Bayesian Model for Sparse Temporal Multigraphs

arXiv.org Machine Learning

As the availability and importance of temporal interaction data--such as email communication--increases, it becomes increasingly important to understand the underlying structure that underpins these interactions. Often these interactions form a multigraph, where we might have multiple interactions between two entities. Such multigraphs tend to be sparse yet structured, and their distribution often evolves over time. Existing statistical models with interpretable parameters can capture some, but not all, of these properties. We propose a dynamic nonparametric model for interaction multigraphs that combines the sparsity of edge-exchangeable multigraphs with dynamic clustering patterns that tend to reinforce recent behavioral patterns. We show that our method yields improved held-out likelihood over stationary variants, and impressive predictive performance against a range of state-of-the-art dynamic graph models.

Women Workers Will Be Most Hit Once AI Becomes the Norm

#artificialintelligence

The adoption of AI could take a toll on women's employment, over the next ten years, says a recent report by McKinsey global institute McKinsey Global Institute report "The future of women at work: Transitions in the age of automation, published earlier this year says the adoption of AI could take a toll on women's employment. It has found that the world's ten economies, – Canada, France, Germany, Japan, the U.K., the U.S., China, India, Mexico, and South America- that collectively contribute over 60% of GDP of the world, will be severely affected by AI adoption, especially for women's employment. The report says, "an average of 20% of women working today (107 million) could find their jobs displaced by 2030. That's compared with 21% of men (163 million) in the same period". As she spoke about the research at MIT Technology Review's EmTech MIT conference at the MIT Media Lab, Krishnan said that almost 90% of the jobs that are repetitive can be automated, in about 10% of occupations.


The 2018 Survey: AI and the Future of Humans

#artificialintelligence

"Please think forward to the year 2030. Analysts expect that people will become even more dependent on networked artificial intelligence (AI) in complex digital systems. Some say we will continue on the historic arc of augmenting our lives with mostly positive results as we widely implement these networked tools. Some say our increasing dependence on these AI and related systems is likely to lead to widespread difficulties. Our question: By 2030, do you think it is most likely that advancing AI and related technology systems will enhance human capacities and empower them? That is, most of the time, will most people be better off than they are today? Or is it most likely that advancing AI and related technology systems will lessen human autonomy and agency to such an extent that most people will not be better off than the way things are today? Please explain why you chose the answer you did and sketch out a vision of how the human-machine/AI collaboration will function in 2030.


Number of Japanese language schools soaring in Asia, survey finds

The Japan Times

About 3.85 million people studied Japanese at a record 18,604 institutions overseas in fiscal 2018, with the number of institutions soaring in Asia, according to a survey released this week. The number of Japanese language institutions jumped nearly fourfold to 818 in Vietnam from the previous survey in fiscal 2015 and nearly tripled to 400 in Myanmar, said the survey by the Japan Foundation, a government-backed organization conducting international cultural exchange programs. The number of Japanese learners overseas rose 5.2 percent to 3,846,773, led by a 169.0 percent surge to 174,461 in Vietnam, it said. The survey found a record high 142 countries and territories offering Japanese language education, five more than the fiscal 2015 level. The five include East Timor, Zimbabwe and Montenegro.


Regret Analysis of Causal Bandit Problems

arXiv.org Machine Learning

We study how to learn optimal interventions sequentially given causal information represented as a causal graph along with associated conditional distributions. Causal modeling is useful in real world problems like online advertisement where complex causal mechanisms underlie the relationship between interventions and outcomes. We propose two algorithms, causal upper confidence bound (C-UCB) and causal Thompson Sampling (C-TS), that enjoy improved cumulative regret bounds compared with algorithms that do not use causal information. We thus resolve an open problem posed by~\cite{lattimore2016causal}. Further, we extend C-UCB and C-TS to the linear bandit setting and propose causal linear UCB (CL-UCB) and causal linear TS (CL-TS) algorithms. These algorithms enjoy a cumulative regret bound that only scales with the feature dimension. Our experiments show the benefit of using causal information. For example, we observe that even with a few hundreds of iterations, the regret of causal algorithms is less than that of standard algorithms by a factor of three. We also show that under certain causal structures, our algorithms scale better than the standard bandit algorithms as the number of interventions increases.


A simple and effective hybrid genetic search for the job sequencing and tool switching problem

arXiv.org Artificial Intelligence

The job sequencing and tool switching problem (SSP) has been extensively studied in the field of operations research, due to its practical relevance and methodological interest. Given a machine that can load a limited amount of tools simultaneously and a number of jobs that require a subset of the available tools, the SSP seeks a job sequence that minimizes the number of tool switches in the machine. To solve this problem, we propose a simple and efficient hybrid genetic search based on a generic solution representation, a tailored decoding operator, efficient local searches and diversity management techniques. To guide the search, we introduce a secondary objective designed to break ties. These techniques allow to explore structurally different solutions and escape local optima. As shown in our computational experiments on classical benchmark instances, our algorithm significantly outperforms all previous approaches while remaining simple to apprehend and easy to implement. We finally report results on a new set of larger instances to stimulate future research and comparative analyses.


Toward Artificial Sentience, Significant Futures Work, and more

#artificialintelligence

An autonomous idea-creation system that already has invented patentable concepts has itself now been patented. The U.S. Patent and Trade Office has awarded a patent to Stephen L. Thaler, president and CEO of Imagination Engines Inc., for his Device for the Autonomous Bootstrapping of Unified Sentience (DABUS). Formally, the patent is titled "Electro‐Optical Device and Method for Identifying and Inducing Topological States Formed Among Interconnecting Neural Modules," which Thaler says constitutes a "successor to deep learning and the future of artificial general intelligence." With DABUS, "vast swarms of neural nets join to form chains that encode concepts gleaned from their environment," Thaler said in a press release. "It also teaches the noise‐stimulation of such neural chaining systems to generate derivative concepts from their accumulated experience (i.e., idea formation)."
