Orange County man pleads guilty to stalking Canadian 'World of Warcraft' gamer
A former Marine from Orange County pleaded guilty Monday to a federal stalking charge after he ran a lengthy harassment campaign against a professional gamer from Canada, according to authorities. Evan Baltierra, 29, of Trabuco Canyon faces up to five years in prison, according to the U.S. attorney's office for the Central District of California. Baltierra moderated the gamer's online channel, where she streamed live video of herself playing the popular multiplayer online role-playing game "World of Warcraft," after she and Baltierra met online, according to charging documents filed in federal court. They first met in person at the BlizzCon convention in Anaheim in November 2019, where the victim held a meet-and-greet event with her fans, according to the documents. Baltierra asked the woman to be his "valentine" online, but she refused because she was in a relationship.
Asia experts seek Japan's lead in rules-based order after Kishida win
Asian security experts have welcomed the victory by Prime Minister Fumio Kishida's ruling coalition in Sunday's House of Councilors election, saying Japan's political stability and leadership are vital for shoring up a rules-based international order being challenged by countries such as China and Russia. Citing Russia's aggression in Ukraine, China's increased assertiveness in the Indo-Pacific and North Korea's nuclear and missile development, the experts either expressed support for or did not oppose Kishida's calls for boosting Japan's defense capabilities and amending the Constitution, including adding a reference to the Self-Defense Forces in the war-renouncing Article 9.

Rob Reich: AI developers need a code of responsible conduct
We are excited to bring Transform 2022 back in-person July 19 and virtually July 20 - 28. Join AI and data leaders for insightful talks and exciting networking opportunities. Rob Reich wears many hats: political philosopher, director of the McCoy Family Center for Ethics in Society, and associate director of the Stanford Institute for Human-Centered Artificial Intelligence. In recent years, Reich has delved deeply into the ethical and political issues posed by revolutionary technological advances in artificial intelligence (AI). His work is not always easy for technologists to hear. In his book, System Error: Where Big Tech Went Wrong and How We Can Reboot, Reich and his co-authors (computer scientist Mehran Sahami and social scientist Jeremy M. Weinstein) argued that tech companies and developers are so fixated on "optimization" that they often trample on human values.
Russia-Ukraine live news: Iran to send Moscow armed drones
The Prime Minister of the Netherlands, Mark Rutte, has met with Zelenskyy in Kyiv and reaffirmed his country's support for Ukraine "politically, militarily and economically." Rutte said he visited "various place where the Russian army has left behind a horrific trail of death and destruction. I am deeply shocked by what I witnessed today". "These appalling crimes must not go unpunished. This is also the subject of the Ukraine Accountability Conference which will be held later this week in The Hague," Rutte said, adding that the conference is organised by the Dutch government, the International Criminal Court and the European Commission.
A Conceptual Framework for Using Machine Learning to Support Child Welfare Decisions
Chor, Ka Ho Brian, Rodolfa, Kit T., Ghani, Rayid
Human services systems make key decisions that impact individuals in the society. The U.S. child welfare system makes such decisions, from screening-in hotline reports of suspected abuse or neglect for child protective investigations, placing children in foster care, to returning children to permanent home settings. These complex and impactful decisions on children's lives rely on the judgment of child welfare decisionmakers. Child welfare agencies have been exploring ways to support these decisions with empirical, data-informed methods that include machine learning (ML). This paper describes a conceptual framework for ML to support child welfare decisions. The ML framework guides how child welfare agencies might conceptualize a target problem that ML can solve; vet available administrative data for building ML; formulate and develop ML specifications that mirror relevant populations and interventions the agencies are undertaking; deploy, evaluate, and monitor ML as child welfare context, policy, and practice change over time. Ethical considerations, stakeholder engagement, and avoidance of common pitfalls underpin the framework's impact and success. From abstract to concrete, we describe one application of this framework to support a child welfare decision. This ML framework, though child welfare-focused, is generalizable to solving other public policy problems.
dpart: Differentially Private Autoregressive Tabular, a General Framework for Synthetic Data Generation
Mahiou, Sofiane, Xu, Kai, Ganev, Georgi
We propose a general, flexible, and scalable framework dpart, an open source Python library for differentially private synthetic data generation. Central to the approach is autoregressive modelling -- breaking the joint data distribution to a sequence of lower-dimensional conditional distributions, captured by various methods such as machine learning models (logistic/linear regression, decision trees, etc.), simple histogram counts, or custom techniques. The library has been created with a view to serve as a quick and accessible baseline as well as to accommodate a wide audience of users, from those making their first steps in synthetic data generation, to more experienced ones with domain expertise who can configure different aspects of the modelling and contribute new methods/mechanisms. Specific instances of dpart include Independent, an optimized version of PrivBayes, and a newly proposed model, dp-synthpop. Code: https://github.com/hazy/dpart
On Curating Responsible and Representative Healthcare Video Recommendations for Patient Education and Health Literacy: An Augmented Intelligence Approach
Pothugunta, Krishna, Liu, Xiao, Susarla, Anjana, Padman, Rema
Studies suggest that one in three US adults use the Internet to diagnose or learn about a health concern. However, such access to health information online could exacerbate the disparities in health information availability and use. Health information seeking behavior (HISB) refers to the ways in which individuals seek information about their health, risks, illnesses, and health-protective behaviors. For patients engaging in searches for health information on digital media platforms, health literacy divides can be exacerbated both by their own lack of knowledge and by algorithmic recommendations, with results that disproportionately impact disadvantaged populations, minorities, and low health literacy users. This study reports on an exploratory investigation of the above challenges by examining whether responsible and representative recommendations can be generated using advanced analytic methods applied to a large corpus of videos and their metadata on a chronic condition (diabetes) from the YouTube social media platform. The paper focusses on biases associated with demographic characters of actors using videos on diabetes that were retrieved and curated for multiple criteria such as encoded medical content and their understandability to address patient education and population health literacy needs. This approach offers an immense opportunity for innovation in human-in-the-loop, augmented-intelligence, bias-aware and responsible algorithmic recommendations by combining the perspectives of health professionals and patients into a scalable and generalizable machine learning framework for patient empowerment and improved health outcomes.
ParaNames: A Massively Multilingual Entity Name Corpus
Sälevä, Jonne, Lignos, Constantine
We introduce ParaNames, a multilingual parallel name resource consisting of 118 million names spanning across 400 languages. Names are provided for 13.6 million entities which are mapped to standardized entity types (PER/LOC/ORG). Using Wikidata as a source, we create the largest resource of this type to-date. We describe our approach to filtering and standardizing the data to provide the best quality possible. ParaNames is useful for multilingual language processing, both in defining tasks for name translation/transliteration and as supplementary data for tasks such as named entity recognition and linking. We demonstrate an application of ParaNames by training a multilingual model for canonical name translation to and from English. Our resource is released under a Creative Commons license (CC BY 4.0) at https://github.com/bltlab/paranames.
Can Machines Learn Morality? The Delphi Experiment
Jiang, Liwei, Hwang, Jena D., Bhagavatula, Chandra, Bras, Ronan Le, Liang, Jenny, Dodge, Jesse, Sakaguchi, Keisuke, Forbes, Maxwell, Borchardt, Jon, Gabriel, Saadia, Tsvetkov, Yulia, Etzioni, Oren, Sap, Maarten, Rini, Regina, Choi, Yejin
As AI systems become increasingly powerful and pervasive, there are growing concerns about machines' morality or a lack thereof. Yet, teaching morality to machines is a formidable task, as morality remains among the most intensely debated questions in humanity, let alone for AI. Existing AI systems deployed to millions of users, however, are already making decisions loaded with moral implications, which poses a seemingly impossible challenge: teaching machines moral sense, while humanity continues to grapple with it. To explore this challenge, we introduce Delphi, an experimental framework based on deep neural networks trained directly to reason about descriptive ethical judgments, e.g., "helping a friend" is generally good, while "helping a friend spread fake news" is not. Empirical results shed novel insights on the promises and limits of machine ethics; Delphi demonstrates strong generalization capabilities in the face of novel ethical situations, while off-the-shelf neural network models exhibit markedly poor judgment including unjust biases, confirming the need for explicitly teaching machines moral sense. Yet, Delphi is not perfect, exhibiting susceptibility to pervasive biases and inconsistencies. Despite that, we demonstrate positive use cases of imperfect Delphi, including using it as a component model within other imperfect AI systems. Importantly, we interpret the operationalization of Delphi in light of prominent ethical theories, which leads us to important future research questions.
Training Robust Deep Models for Time-Series Domain: Novel Algorithms and Theoretical Analysis
Belkhouja, Taha, Yan, Yan, Doppa, Janardhan Rao
Despite the success of deep neural networks (DNNs) for real-world applications over time-series data such as mobile health, little is known about how to train robust DNNs for time-series domain due to its unique characteristics compared to images and text data. In this paper, we propose a novel algorithmic framework referred as RObust Training for Time-Series (RO-TS) to create robust DNNs for time-series classification tasks. Specifically, we formulate a min-max optimization problem over the model parameters by explicitly reasoning about the robustness criteria in terms of additive perturbations to time-series inputs measured by the global alignment kernel (GAK) based distance. We also show the generality and advantages of our formulation using the summation structure over time-series alignments by relating both GAK and dynamic time warping (DTW). This problem is an instance of a family of compositional min-max optimization problems, which are challenging and open with unclear theoretical guarantee. We propose a principled stochastic compositional alternating gradient descent ascent (SCAGDA) algorithm for this family of optimization problems. Unlike traditional methods for time-series that require approximate computation of distance measures, SCAGDA approximates the GAK based distance on-the-fly using a moving average approach. We theoretically analyze the convergence rate of SCAGDA and provide strong theoretical support for the estimation of GAK based distance. Our experiments on real-world benchmarks demonstrate that RO-TS creates more robust DNNs when compared to adversarial training using prior methods that rely on data augmentation or new definitions of loss functions. We also demonstrate the importance of GAK for time-series data over the Euclidean distance. The source code of RO-TS algorithms is available at https://github.com/tahabelkhouja/Robust-Training-for-Time-Series
