Beyond Message Passing: a Physics-Inspired Paradigm for Graph Neural Networks

#artificialintelligence

The message-passing paradigm has been the "battle horse" of deep learning on graphs for several years, making graph neural networks a big success in a wide range of applications, from particle physics to protein design. From a theoretical viewpoint, it established the link to the Weisfeiler-Lehman hierarchy, allowing to analyse the expressive power of GNNs. We argue that the "node and edge-centric" mindset of current graph deep learning schemes imposes strong limitations that hinder future progress in the field. As an alternative, we propose physics-inspired "continuous" learning models that open up a new trove of tools from the fields of differential geometry, algebraic topology, and differential equations so far largely unexplored in graph ML. Graphs are a convenient way to abstract complex systems of relations and interactions. The increasing prominence of graph-structured data from social networks to high-energy physics to chemistry, and a series of high-impact successes have made deep learning on graphs one of the hottest topics in machine learning research [1]. Graph Neural Networks (GNNs) are by far the most common among graph ML methods and the most popular neural network architectures overall [2]. Graph neural networks take as input a graph endowed with node and edge features and compute a function that depends both on the features and the graph structure. Message-passing type GNNs, also called Message Passing Neural Networks (MPNN) [3], propagate node features by exchanging information between adjacent nodes. A typical MPNN architecture has several propagation layers, where each node is updated based on the aggregation of its neighbours' features.



Council Post: The AI Learning Revolution And The End Of One-Size-Fits-All Learning

#artificialintelligence

Markus Bernhardt is the Chief Evangelist at Obrizum, pioneering deeptech AI digital learning solutions for corporate learning. Google Director of Research Peter Norvig famously stated in his keynote speech for the Association for Learning Technology Conference in 2007 that if you only had to read one research paper to learn about learning, it would be Benjamin Bloom's The 2 Sigma Problem: The Search for Methods of Group Instruction as Effective as One-to-One Tutoring. To aid his preparation for the keynote, this brilliant piece of advice had been given to Peter by his friend Hal Abelson, an educator and professor at MIT. In Bloom's well-known and often-cited paper, the outcome of an experiment is reported comparing the efficacy of three types of teaching: the conventional lecture, the conventional lecture with regular testing and feedback, and one-to-one tuition. Using the "straight lecture" as the mean, Bloom found an 84% increase in mastery above the mean for a "formative feedback" approach to teaching and an astonishing 98% increase in mastery for one-to-one tuition.


Deaf education vote is the latest parents' rights battleground in L.A.

Los Angeles Times

The Los Angeles Unified School District is poised to vote on a controversial proposal that could reshape education for thousands of deaf and hard-of-hearing students, a key battle in a long national fight over how such children learn language. Oscar winner Marlee Matlin and the American Civil Liberties Union are among those urging the Board of Education to pass Resolution 029-21/22 at its meeting Tuesday, inaugurating a new Department of Deaf and Hard of Hearing Education. Students would be eligible to receive the state seal of biliteracy on their diplomas, and ASL would be offered as a language course in some high schools. The resolution also would introduce ASL-English bilingual instruction for many of the district's youngest deaf learners -- a move supporters say is critical to language equity and opponents say robs parents of choice and runs afoul of federal education law. "For 400 years at least there's been a big battle between people who think children with hearing loss should speak, and people who think they should use sign language -- it's a very old argument," said Alison M. Grimes, director of audiology and newborn hearing at UCLA Health.

AI For Everyone

#artificialintelligence

AI is not only for engineers. If you want your organization to become better at using AI, this is the course to tell everyone--especially your non-technical colleagues--to take. In this course, you will learn: - The meaning behind common AI terminology, including neural networks, machine learning, deep learning, and data science - What AI realistically can--and cannot--do - How to spot opportunities to apply AI to problems in your own organization - What it feels like to build machine learning and data science projects - How to work with an AI team and build an AI strategy in your company - How to navigate ethical and societal discussions surrounding AI Though this course is largely non-technical, engineers can also take this course to learn the business aspects of AI.

Using machine learning to improve student success in higher education

#artificialintelligence

Many higher-education institutions are now using data and analytics as an integral part of their processes. Whether the goal is to identify and better support pain points in the student journey, more efficiently allocate resources, or improve student and faculty experience, institutions are seeing the benefits of data-backed solutions. This article is a collaborative effort by Claudio Brasca, Nikhil Kaithwal, Charag Krishnan, Monatrice Lam, Jonathan Law, and Varun Marya, representing views from McKinsey's Public & Social Sector Practice. Those at the forefront of this trend are focusing on harnessing analytics to increase program personalization and flexibility, as well as to improve retention by identifying students at risk of dropping out and reaching out proactively with tailored interventions. Indeed, data science and machine learning may unlock significant value for universities by ensuring resources are targeted toward the highest-impact opportunities to improve access for more students, as well as student engagement and satisfaction.


Rethinking Fairness: An Interdisciplinary Survey of Critiques of Hegemonic ML Fairness Approaches

Journal of Artificial Intelligence Research

This survey article assesses and compares existing critiques of current fairness-enhancing technical interventions in machine learning (ML) that draw from a range of non-computing disciplines, including philosophy, feminist studies, critical race and ethnic studies, legal studies, anthropology, and science and technology studies. It bridges epistemic divides in order to offer an interdisciplinary understanding of the possibilities and limits of hegemonic computational approaches to ML fairness for producing just outcomes for society's most marginalized. The article is organized according to nine major themes of critique wherein these different fields intersect: 1) how "fairness" in AI fairness research gets defined; 2) how problems for AI systems to address get formulated; 3) the impacts of abstraction on how AI tools function and its propensity to lead to technological solutionism; 4) how racial classification operates within AI fairness research; 5) the use of AI fairness measures to avoid regulation and engage in ethics washing; 6) an absence of participatory design and democratic deliberation in AI fairness considerations; 7) data collection practices that entrench "bias," are non-consensual, and lack transparency; 8) the predatory inclusion of marginalized groups into AI systems; and 9) a lack of engagement with AI's long-term social and ethical outcomes. Drawing from these critiques, the article concludes by imagining future ML fairness research directions that actively disrupt entrenched power dynamics and structural injustices in society.


Ten HR Trends In The Age Of Artificial Intelligence

#artificialintelligence

The future of HR is both digital and human as HR leaders focus on optimizing the combination of human and automated work. This is driving a new priority for HR: one which requires leaders and teams to develop a fluency in artificial intelligence while they re-imagine HR to be more personal, human and intuitive. As we enter 2019, it's the combination of AI and human intelligence that will transform work and workers as we know it. For many companies the first pilots of artificial intelligence are in talent acquisition, as this is the area where companies see significant, measurable, and immediate results in reducing time to hire, increasing productivity for recruiters, and delivering an enhanced candidate experience that is seamless, simple, and intuitive. One company that has delivered on this is DBS Bank.
