To better retain talent in its ranks, the Marine Corps is turning to machine learning and artificial intelligence to examine recruiting data and identify key attributes of Marines who will likely stay in uniform. The military writ large has struggled to retain specialized skills, especially tech talent, so the Marine Corps has turned to tech to identify key traits in recruits to inform management choices around retention. The new tech is aimed at enabling a broader transition in Marine Corps to better focus on retention -- rather than just recruitment -- and use analytics to inform decisions aroun Marines upon their entry into service. "The intended outcome is to decrease [Marine Corps Recruit Depot] attrition and increase the success of applicants through at least their first term of enlistment," Maj. Jordan Cochran, a spokesman for the corps' Manpower and Reserve Affairs Department, said in an email.

Artificial Intelligence (AI), is a societal buzzword that now crosses every area of human experience. Whether it is our leisure activities, our medical interventions, our banking transactions or our shopping pursuits, AI is now pivotal to the way in which we conduct our personal lives. This phenomenon has not emerged haphazardly, but is a trajectory that has ensued from the benefits that business has enjoyed from its use, and one that now every area of commerce needs to employ, and maintain, in order to enjoy any success. According to IBM, 65 percent of all organisations will have accelerated the use of digital technologies by 2022 and more than 85 percent of advanced adopters are reducing operating costs. Artificial Intelligence is here to stay.

The AIPPF, established in 2020 by the Bank of England and the Financial Conduct Authority (FCA), was set up to facilitate dialogue between the private sector, public sector, and academia regarding AI. Data comes first: The report describes data as foundational for AI, attributing most of AI's recent growth to a surge in the availability of data to contribute to models. Data is more connected to AI's pros and cons than other aspects, and "many of the benefits and risks can be traced back to the data, rather than the AI systems or algorithms themselves." Data is also among "the defining features of AI," which can process massive quantities of data and find patterns from it. The report honed in on key areas for banks' data operations for AI, such as: Data quality: This covers accuracy, timeliness, transparency, and completeness. Banks' quality challenges include needing to update their controls and processes for AI, and handling complex data sources.

Taxpayers in the US don't have to use facial recognition or any kind of biometric data to access their accounts online if they don't want to. The IRS has announced that users can opt for a live, virtual interview to authenticate their identity instead of registering for an ID.me account. This move comes a few weeks after the agency said it will back away from using facial recognition following pressure from both sides of the political aisle. Both Republican and Democratic lawmakers raised concerns about the privacy and security implications of using ID.me facial recognition and how it will make the IRS a prime target of cyberattacks. To sign up for an ID.me account, taxpayers will have to send the service a copy of their government ID, a utility bill and a video selfie of themselves.

Web 3.0 is the generation of interest where apps and websites can analyze data like a human with the help of Machine Learning, Big Data, and decentralized ledger technologies. Data here is decentralized and open, unlike Web 2.0 and it is autonomous and intelligent. Cybersecurity is the most important in the technology world. And as Web 3.0 develops, more cybersecurity risks will come to light. At present risks like Information quality, Data Availability, Data Confidentiality, and Data Manipulation are being the major concerns.

Maintaining artificial intelligence while ensuring data privacy is a challenging feat to do. While artificial intelligence holds a lot of promise, it also raises worries about data misuse and personal privacy breaches. AI must operate in a robust, secure, and safe manner, with risks constantly reviewed and addressed. Organizations that create AI must be accountable for ensuring that these systems operate in accordance with these principles. The EU Artificial intelligence Act has introduced a sophisticated'product safety framework' built around a set of four risk categories.

Deep reinforcement learning (DRL) is a promising outer-loop intelligence paradigm which can deploy problem solving strategies for complex tasks. Consequently, DRL has been utilized for several scientific applications, specifically in cases where classical optimization or control methods are limited. One key limitation of conventional DRL methods is their episode-hungry nature which proves to be a bottleneck for tasks which involve costly evaluations of a numerical forward model. In this article, we address this limitation of DRL by introducing a controlled transfer learning framework that leverages a multi-fidelity simulation setting. Our strategy is deployed for an airfoil shape optimization problem at high Reynolds numbers, where our framework can learn an optimal policy for generating efficient airfoil shapes by gathering knowledge from multi-fidelity environments and reduces computational costs by over 30\%. Furthermore, our formulation promotes policy exploration and generalization to new environments, thereby preventing over-fitting to data from solely one fidelity. Our results demonstrate this framework's applicability to other scientific DRL scenarios where multi-fidelity environments can be used for policy learning.

Since model bias and associated initialization shock are serious shortcomings that reduce prediction skills in state-of-the-art decadal climate prediction efforts, we pursue a complementary machine-learning-based approach to climate prediction. The example problem setting we consider consists of predicting natural variability of the North Atlantic sea surface temperature on the interannual timescale in the pre-industrial control simulation of the Community Earth System Model (CESM2). While previous works have considered the use of recurrent networks such as convolutional LSTMs and reservoir computing networks in this and other similar problem settings, we currently focus on the use of feedforward convolutional networks. In particular, we find that a feedforward convolutional network with a Densenet architecture is able to outperform a convolutional LSTM in terms of predictive skill. Next, we go on to consider a probabilistic formulation of the same network based on Stein variational gradient descent and find that in addition to providing useful measures of predictive uncertainty, the probabilistic (Bayesian) version improves on its deterministic counterpart in terms of predictive skill. Finally, we characterize the reliability of the ensemble of ML models obtained in the probabilistic setting by using analysis tools developed in the context of ensemble numerical weather prediction.

Estimating heterogeneous treatment effects in domains such as healthcare or social science often involves sensitive data where protecting privacy is important. We introduce a general meta-algorithm for estimating conditional average treatment effects (CATE) with differential privacy (DP) guarantees. Our meta-algorithm can work with simple, single-stage CATE estimators such as S-learner and more complex multi-stage estimators such as DR and R-learner. We perform a tight privacy analysis by taking advantage of sample splitting in our meta-algorithm and the parallel composition property of differential privacy. In this paper, we implement our approach using DP-EBMs as the base learner. DP-EBMs are interpretable, high-accuracy models with privacy guarantees, which allow us to directly observe the impact of DP noise on the learned causal model. Our experiments show that multi-stage CATE estimators incur larger accuracy loss than single-stage CATE or ATE estimators and that most of the accuracy loss from differential privacy is due to an increase in variance, not biased estimates of treatment effects.
