World University Law School - World University and School Wiki

#artificialintelligence

Welcome to World University and School Wiki which anyone can add to or edit. WUaS would like to offer online CLE credits with these great universities, anticipating accrediting WUaS Law Schools in 204 countries. California, the state in which WUaS is incorporated, has 12 online law schools (none of these are ABA approved, but anyone can sit the California Bar exam, regardless of such approval, as I understand it), at present, and WUaS would like to develop another online MIT OCW/Harvard-centric law school, and eventually accredit in all 204 countries in the world, in main languages in those countries, beginning with the 6 United Nations' languages. Online Law Schools Have Yet to Pass the Bar: Many argue that fully online programs aren't the path to a traditional legal career]. WUaS is planning for a "Admitted Students' Day" for the first, matriculating Bachelor's degree class, on or around Saturday, April 14th, 2014, and the second Saturday of April for other degrees in the future.


National Artificial Intelligence Research Resource Task Force Releases Final Report

#artificialintelligence

Today, the National Artificial Intelligence Research Resource (NAIRR) Task Force released its final report, a roadmap for standing up a national research infrastructure that would broaden access to the resources essential to artificial intelligence (AI) research and development. While AI research and development (R&D) in the United States is advancing rapidly, opportunities to pursue cutting-edge AI research and new AI applications are often inaccessible to researchers beyond those at well-resourced companies, organizations, and academic institutions. A NAIRR would change that by providing AI researchers and students with significantly expanded access to computational resources, high-quality data, educational tools, and user support--fueling greater innovation and advancing AI that serves the public good. "AI advances hold tremendous promise for tackling our hardest problems and achieving our greatest aspirations," said Arati Prabhakar, OSTP Director and Assistant to the President for Science and Technology. "We will only realize this potential when many more kinds of researchers have access to the powerful capabilities that underpin AI advances."


The biggest AI breakthroughs of the last year

#artificialintelligence

In 2022, we were presented with several stunning developments in artificial intelligence (AI). Some believe that these advances push the limits of what we have now (narrow AI) towards the holy grail of artificial general intelligence (a machine that can mimic the thinking and problem-solving capacities of humans but faster and more accurately). Among the many developments in 2022, four breakthroughs are of note and will be significant in 2023 and beyond both within the discussions on responsible design development and AI use and in the transformative power they have for our societies. First came DALL-E, the AI that can create pictures from language prompts. Many of us enjoyed playing with the tool and embracing the ability it gave to us to design in new ways. Others worried about AI taking over our human creativity.


Warn your children: Robots and AI are coming for their careers

#artificialintelligence

For five years or so, I have been running around as a pale imitation of Paul Revere, yelling, "The robots are coming! At schools, social settings, with family and friends, or even to complete strangers with whom I fell into conversations, I have uttered the same warning: "It's critical that you or your children identify a career -- now -- that won't be taken over by robots and artificial intelligence." My particular midnight ride started well before the pandemic reared its ugly head. But the pandemic may have planted a seed in the minds of certain CEOs that human beings are the weakest link on their chain to profit and prosperity. When the first "Terminator" movie was released -- eerily enough, in 1984 -- the world was introduced to Cyberdyne Systems and its "Skynet" artificial superintelligence system, which not only gained self-awareness but realized it could do everything infinitely faster and better than its human creators. Well, ever since that movie got people asking, "What if," the fictional theme -- and warnings about AI -- have been morphing into reality. The latest example of a technology poised to replace a human workforce is ChatGPT, the chatbot auto-generative system created by Open AI for online customer care. It is a pre-trained generative chat, which makes use of natural language processing, or NLP. The source of its data is textbooks, websites and various articles, which it uses to model its own language for responding to human interaction. It's certainly not a stretch to believe that any number of CEOs might think, "Interestingโ€ฆ A self-teaching artificial intelligence system that won't call in sick, doesn't need to be fed or to take bathroom breaks, does not require health care, but can and will work 24/7/365." Not shockingly, it has been reported that Microsoft, which is laying off 10,000 people, announced a "multiyear, multibillion-dollar investment" in this revolutionary technology, which apparently is growing smarter by the day. Pengcheng Shi, an associate dean in the Department of Computing and Information Sciences at Rochester Institute of Technology, warned in an interview with the New York Post: "AI is replacing the white-collar workers.


An AI app that can spot deepfake videos of famous people

#artificialintelligence

A pair of researchers, one with Gymnasium of Johannes Kepler, the other with the University of California, Berkley, has developed an artificial intelligence (AI) application capable of determining whether a video clip of a famous person is genuine or a deepfake. In their paper published in Proceedings of the National Academy of Sciences, Matyรกลก Bohรกฤek and Hany Farid describe training their AI system to recognize unique body movements of certain individuals to discern whether a video was real or not. As deepfake technology has grown more sophisticated, it has become more difficult to determine whether a video is genuine. In the realm of public figures, such videos can become problematic. Such was the case when parties in Russia created a recent deepfake video of Ukraine president Volodymyr Zelenskyy saying things that he did not actually say--a video that was reportedly created to help the Russian government convince its citizenry of Russian state propaganda regarding the invasion of Ukraine.


10 Technical Blogs for Data Scientists to Advance AI/ML Skills

#artificialintelligence

Savvy data scientists are already applying artificial intelligence and machine learning to accelerate the scope and scale of data-driven decisions in strategic organizations. These data science teams are seeing tremendous results--millions of dollars saved, new customers acquired, and new innovations that create a competitive advantage. Other organizations are just discovering how to apply AI to accelerate experimentation time frames and find the best models to produce results. Data scientists are in demand: the U.S. Bureau of Labor Statistics predicts that the employment of data scientists will grow 36 percent by 2031,1 much faster than the average for all occupations. Data scientists are also some of the highest-paid job roles, so data scientists need to quickly show their value by getting to real results as quickly, safely, and accurately as possible.


Collective Robustness Certificates: Exploiting Interdependence in Graph Neural Networks

arXiv.org Artificial Intelligence

In tasks like node classification, image segmentation, and named-entity recognition we have a classifier that simultaneously outputs multiple predictions (a vector of labels) based on a single input, i.e. a single graph, image, or document respectively. Existing adversarial robustness certificates consider each prediction independently and are thus overly pessimistic for such tasks. They implicitly assume that an adversary can use different perturbed inputs to attack different predictions, ignoring the fact that we have a single shared input. We propose the first collective robustness certificate which computes the number of predictions that are simultaneously guaranteed to remain stable under perturbation, i.e. cannot be attacked. We focus on Graph Neural Networks and leverage their locality property - perturbations only affect the predictions in a close neighborhood - to fuse multiple single-node certificates into a drastically stronger collective certificate. For example, on the Citeseer dataset our collective certificate for node classification increases the average number of certifiable feature perturbations from 7 to 351 . Most classifiers are vulnerable to adversarial attacks (Akhtar & Mian, 2018; Hao-Chen et al., 2020). Slight perturbations of the data are often sufficient to manipulate their predictions. Even in scenarios where attackers are not present it is critical to ensure that models are robust since data can be noisy, incomplete, or anomalous. We study classifiers that collectively output many predictions based on a single input. This includes node classification, link prediction, molecular property prediction, image segmentation, part-of-speech tagging, named-entity recognition, and many other tasks. V arious techniques have been proposed to improve the adversarial robustness of such models. One example is adversarial training (Goodfellow et al., 2015), which has been applied to part-of-speech tagging (Han et al., 2020), semantic segmentation (Xu et al., 2020b) and node classification (Feng et al., 2019). Graph-related tasks in particular have spawned a rich assortment of techniques. These include Bayesian models (Feng et al., 2020), data-augmentation methods (Entezari et al., 2020) and various robust network architectures (Zhu et al., 2019; Geisler et al., 2020). There are also robust loss functions which either explicitly model an adversary trying to cause misclassifications (Zhou & V orobeychik, 2020) or use regularization terms derived from robustness certificates (Z ugner & G unnemann, 2019). Other methods try to detect adversarially perturbed graphs (Zhang et al., 2019; Xu et al., 2020a) or directly correct perturbations using generative models (Zhang & Ma, 2020).


Confidence-Ranked Reconstruction of Census Microdata from Published Statistics

arXiv.org Artificial Intelligence

A reconstruction attack on a private dataset $D$ takes as input some publicly accessible information about the dataset and produces a list of candidate elements of $D$. We introduce a new class of data reconstruction attacks based on randomized methods for non-convex optimization. We empirically demonstrate that our attacks can not only reconstruct full rows of $D$ from aggregate query statistics $Q(D)\in \mathbb{R}^m$, but can do so in a way that reliably ranks reconstructed rows by their odds of appearing in the private data, providing a signature that could be used for prioritizing reconstructed rows for further actions such as identify theft or hate crime. We also design a sequence of baselines for evaluating reconstruction attacks. Our attacks significantly outperform those that are based only on access to a public distribution or population from which the private dataset $D$ was sampled, demonstrating that they are exploiting information in the aggregate statistics $Q(D)$, and not simply the overall structure of the distribution. In other words, the queries $Q(D)$ are permitting reconstruction of elements of this dataset, not the distribution from which $D$ was drawn. These findings are established both on 2010 U.S. decennial Census data and queries and Census-derived American Community Survey datasets. Taken together, our methods and experiments illustrate the risks in releasing numerically precise aggregate statistics of a large dataset, and provide further motivation for the careful application of provably private techniques such as differential privacy.


Deep Ensembles for Graphs with Higher-order Dependencies

arXiv.org Artificial Intelligence

Graph neural networks (GNNs) continue to achieve state-of-the-art performance on many graph learning tasks, but rely on the assumption that a given graph is a sufficient approximation of the true neighborhood structure. When a system contains higher-order sequential dependencies, we show that the tendency of traditional graph representations to underfit each node's neighborhood causes existing GNNs to generalize poorly. To address this, we propose a novel Deep Graph Ensemble (DGE), which captures neighborhood variance by training an ensemble of GNNs on different neighborhood subspaces of the same node within a higher-order network structure. We show that DGE consistently outperforms existing GNNs on semisupervised and supervised tasks on six real-world data sets with known higher-order dependencies, even under a similar parameter budget. We demonstrate that learning diverse and accurate base classifiers is central to DGE's success, and discuss the implications of these findings for future work on ensembles of GNNs.


An Empirical Analysis of Fairness Notions under Differential Privacy

arXiv.org Artificial Intelligence

Recent works have shown that selecting an optimal model architecture suited to the differential privacy setting is necessary to achieve the best possible utility for a given privacy budget using differentially private stochastic gradient descent (DP-SGD)(Tramer and Boneh 2020; Cheng et al. 2022). In light of these findings, we empirically analyse how different fairness notions, belonging to distinct classes of statistical fairness criteria (independence, separation and sufficiency), are impacted when one selects a model architecture suitable for DP-SGD, optimized for utility. Using standard datasets from ML fairness literature, we show using a rigorous experimental protocol, that by selecting the optimal model architecture for DP-SGD, the differences across groups concerning the relevant fairness metrics (demographic parity, equalized odds and predictive parity) more often decrease or are negligibly impacted, compared to the non-private baseline, for which optimal model architecture has also been selected to maximize utility. These findings challenge the understanding that differential privacy will necessarily exacerbate unfairness in deep learning models trained on biased datasets.
