Cybersecurity & Neuroscience Whitepaper - Anti Phishing Solution and Awareness Education
From an organizational standpoint, the goal of any effective cybersecurity awareness platform is to help employees get to a point where they no longer have to actively remember what it takes to keep the company safe – instead, they develop healthy cybersecurity habits. When you walk out the front door in the morning, do you really have to remember to lock the door? When you leave a restaurant or a coffee shop, do you have to remember to grab your wallet or purse? You don't do these things because you recall that criminals sometimes break into homes and steal unattended personal items – you do them habitually. Cybersecurity awareness should be no different.
The Women Defining The 21st Century AI Movement: Part 1 Of 2
In this two-part series I will highlight several of the dozens of women that I believe will lead the 21st century in the field of Artificial Intelligence. Part one is focused on Women in the United States. In 2017 I discussed 9 AI minds you don't know, but should follow. The list included computer scientists, researchers and entrepreneurs as well as other trailblazing individuals. My focus now is to highlight more top minds in AI, but to specifically focus on women who are defining the 21st century's artificial intelligence movement.
aphBO-2GP-3B: A budgeted asynchronously-parallel multi-acquisition for known/unknown constrained Bayesian optimization on high-performing computing architecture
Tran, Anh, McCann, Scott, Furlan, John M., Pagalthivarthi, Krishnan V., Visintainer, Robert J., Wildey, Tim
High-fidelity complex engineering simulations are highly predictive, but also computationally expensive and often require substantial computational efforts. The mitigation of computational burden is usually enabled through parallelism in high-performance cluster (HPC) architecture. In this paper, an asynchronous constrained batch-parallel Bayesian optimization method is proposed to efficiently solve the computationally-expensive simulation-based optimization problems on the HPC platform, with a budgeted computational resource, where the maximum number of simulations is a constant. The advantages of this method are three-fold. First, the efficiency of the Bayesian optimization is improved, where multiple input locations are evaluated massively parallel in an asynchronous manner to accelerate the optimization convergence with respect to physical runtime. This efficiency feature is further improved so that when each of the inputs is finished, another input is queried without waiting for the whole batch to complete. Second, the method can handle both known and unknown constraints. Third, the proposed method considers several acquisition functions at the same time and sample based on an evolving probability mass distribution function using GP-Hedge scheme, where parameters are corresponding to the performance of each acquisition function. The proposed framework is termed aphBO-2GP-3B, which corresponds to asynchronous parallel hedge Bayesian optimization with two Gaussian processes and three batches. The aphBO-2GP-3B framework is demonstrated using two high-fidelity expensive industrial applications, where the first one is based on finite element analysis (FEA) and the second one is based on computational fluid dynamics (CFD) simulations.
Artificial Intelligence: Nurses Integral Role in Deployment
Yale New Haven Hospital nursing staff was one of the earliest users of the Rothman Index. The index is a tool used to reflect acuity and risk levels for patients. Clinical Informatics Manager Leslie Hutchins stated the Yale New Haven Hospital implementation of technology was aiming to provide the right advisory, at the right time, in order to pull the data that is meaningful to the cause of achieving desired patient outcomes. The Rothman index uses electronic medical record data for calculations. The Rothman Index was met by a great deal of skepticism regarding validity and reliability in addition to the accuracy of actionable results.
Non-stationary continuous dynamic Bayesian networks
Grzegorczyk, Marco, Husmeier, Dirk
Dynamic Bayesian networks have been applied widely to reconstruct the structure of regulatory processes from time series data. The standard approach is based on the assumption of a homogeneous Markov chain, which is not valid in many real-world scenarios. Recent research efforts addressing this shortcoming have considered undirected graphs, directed graphs for discretized data, or over-flexible models that lack any information sharing between time series segments. In the present article, we propose a non-stationary dynamic Bayesian network for continuous data, in which parameters are allowed to vary between segments, and in which a common network structure provides essential information sharing across segments. Our model is based on a Bayesian change-point process, and we apply a variant of the allocation sampler of Nobile and Fearnside to infer the number and location of the change-points.
Study shows widely used machine learning methods don't work as claimed
Models and algorithms for analyzing complex networks are widely used in research and affect society at large through their applications in online social networks, search engines, and recommender systems. According to a new study, however, one widely used algorithmic approach for modeling these networks is fundamentally flawed, failing to capture important properties of real-world complex networks. "It's not that these techniques are giving you absolute garbage. They probably have some information in them, but not as much information as many people believe," said C. "Sesh" Seshadhri, associate professor of computer science and engineering in the Baskin School of Engineering at UC Santa Cruz. Seshadhri is first author of a paper on the new findings published March 2 in Proceedings of the National Academy of Sciences.
White House Urges Researchers To Use Artificial Intelligence To Analyse 29,000 Coronavirus Papers - Tunf News
On Monday, the White House's Office of Science and Technology Policy challenged researchers to use artificial intelligence (AI) technology to analyze about 29,000 scholarly articles to answer key questions about the coronavirus. The White House Office announced that it had partnered with companies such as Microsoft and Alphabet's Google to collect the most extensive database of scholarly articles about the virus available to researchers. The US Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) have said they want help to better understand the origins and transmission of the coronavirus in aid of developing a vaccine and treatments. The US Chief Technology Officer Michael Kratsios, who works in the White House, told reporters on a conference call that the hope is that computers will be able to scan the research more quickly than humans and uncover findings that humans may miss. Machine Learning, a form of AI in which software is designed to detect patterns in data on its own, is already used in healthcare and other industries to develop summaries from large amounts of text.
Artificial Intelligence: the urgency for Africa TechCabal
With more than 2000 spoken languages, Africa's linguistic diversity is second only to Asia. A third of the world's languages is spoken by the 1.2 billion people living within her 54 countries. But the language of artificial intelligence is yet to gain fluency. It has become hackneyed to weave AI into every conversation about technology and society. AI will take away jobs.
Reverse KL-Divergence Training of Prior Networks: Improved Uncertainty and Adversarial Robustness
Ensemble approaches for uncertainty estimation have recently been applied to the tasks of misclassification detection, out-of-distribution input detection and adversarial attack detection. Prior Networks have been proposed as an approach to efficiently emulate an ensemble of models for classification by parameterising a Dirichlet prior distribution over output distributions. These models have been shown to outperform alternative ensemble approaches, such as Monte-Carlo Dropout, on the task of out-of-distribution input detection. However, scaling Prior Networks to complex datasets with many classes is difficult using the training criteria originally proposed. This paper makes two contributions.
