Deep neural networks have become a popular algorithm for a variety of applications using mobile devices including smart phones but also recently expanding to connected and autonomous vehicles (CAVs), robotics, or even unmanned aerial vehicles (UAVs), and other smart infrastructure. Convolutional Neural Networks (CNNs) have been demonstrated to provide solutions to these problems with relatively high accuracy. While there have been many proposals to improve the performance and energy efficiency of CNN inference, these algorithms are too compute and data intensive to execute directly on mobile nodes typically operating with limited computational and energy capabilities. Thus, edge servers, now being deployed often in conjunction with advanced (e.g., 5G) wireless networks, have become a popular target to accelerate CNN inference. Moreover, due to their deployment in the field, edge servers must operate under size, weight, and power (SWaP) constraints, while serving many concurrent requests from mobile clients. Thus, to accelerate CNNs, these edge servers often use energy-efficient accelerators, reduced precision, or both to achieve fast response time while balancing requests from multiple clients and maintaining a low operational energy cost. Recently, there has been a trend to push online training to edge server nodes to avoid communicating large datasets from edge to cloud servers [1]. However, online training typically requires much higher precision and floating-point computation compared to inference. Unfortunately, the proliferation of computing, both the mobile devices, and the edge servers themselves, can come at the expense of negative environmental impacts.
A Generative Framework for Personalized Learning and Estimation: Theory, Algorithms, and Privacy
Ozkara, Kaan, Girgis, Antonious M., Data, Deepesh, Diggavi, Suhas
A distinguishing characteristic of federated learning is that the (local) client data could have statistical heterogeneity. This heterogeneity has motivated the design of personalized learning, where individual (personalized) models are trained, through collaboration. There have been various personalization methods proposed in literature, with seemingly very different forms and methods ranging from use of a single global model for local regularization and model interpolation, to use of multiple global models for personalized clustering, etc. In this work, we begin with a generative framework that could potentially unify several different algorithms as well as suggest new algorithms. We apply our generative framework to personalized estimation, and connect it to the classical empirical Bayes' methodology. We develop private personalized estimation under this framework. We then use our generative framework for learning, which unifies several known personalized FL algorithms and also suggests new ones; we propose and study a new algorithm AdaPeD based on a Knowledge Distillation, which numerically outperforms several known algorithms. We also develop privacy for personalized learning methods with guarantees for user-level privacy and composition. We numerically evaluate the performance as well as the privacy for both the estimation and learning problems, demonstrating the advantages of our proposed methods.
Don't Throw it Away! The Utility of Unlabeled Data in Fair Decision Making
Rateike, Miriam, Majumdar, Ayan, Mineeva, Olga, Gummadi, Krishna P., Valera, Isabel
Decision making algorithms, in practice, are often trained on data that exhibits a variety of biases. Decision-makers often aim to take decisions based on some ground-truth target that is assumed or expected to be unbiased, i.e., equally distributed across socially salient groups. In many practical settings, the ground-truth cannot be directly observed, and instead, we have to rely on a biased proxy measure of the ground-truth, i.e., biased labels, in the data. In addition, data is often selectively labeled, i.e., even the biased labels are only observed for a small fraction of the data that received a positive decision. To overcome label and selection biases, recent work proposes to learn stochastic, exploring decision policies via i) online training of new policies at each time-step and ii) enforcing fairness as a constraint on performance. However, the existing approach uses only labeled data, disregarding a large amount of unlabeled data, and thereby suffers from high instability and variance in the learned decision policies at different times. In this paper, we propose a novel method based on a variational autoencoder for practical fair decision-making. Our method learns an unbiased data representation leveraging both labeled and unlabeled data and uses the representations to learn a policy in an online process. Using synthetic data, we empirically validate that our method converges to the optimal (fair) policy according to the ground-truth with low variance. In real-world experiments, we further show that our training approach not only offers a more stable learning process but also yields policies with higher fairness as well as utility than previous approaches.

Sickcare AI Field Notes
There seems to be an inherent conflict between using AI to standardize decisions compared to using it for mass customization. Efforts to develop customized care must be designed around a deep understanding of what happens at the ground level along the patient pathway and must incorporate patient engagement by focusing on such things as shared decision-making, definition of appointments, and self-management, all of which are elements of a "build-to-order" approach. When it comes to dissemination and implementation, culture eats strategy for lunch. The majority of the conversations had to do with the technical aspects and use cases for AI. A small amount was about how to get people in your organization to understand and use it. The goal is to empower clinical teams to collaborate with patient teams and that will take some work. Moving sick care to healthcare also requires changing a sprint mindset to a marathon relay race mindset with all the hazards and risks of dropped handoffs and referral and information management leaks. AI is a facilitating technology that cuts across many applications, use cases and intended uses in sick care. Some day we might be recruiting medical students, residents and other sick care workers using AI instead of those silly resumes.
3 Strategies for Helping Students Navigate the Ethics of Artificial Intelligence
Imagine a stuffed animal that can record children and transmit the recording to their parents. If the child is getting bullied at school, the parent will find out. But is it ethical to record one's own child without their knowledge or consent? Does it matter how old the children are? Eamon Marchant, a STEM teacher and technology coordinator at Whitney High School in Cerritos, Calif., presents quandaries like this to his students all the time.
The opportunity at home – can AI drive innovation in personal assistant devices and sign language? - Microsoft Accessibility Blog
Additionally, a summarization of command categories and frequencies showed the most popular category was "command and control" where users adjust device settings, navigate through the results and answer yes/no style of questions. The next popular category was related to entertainment questions, followed by lifestyle and shopping. Furthermore, despite signing into a device, participants made sophisticated use of the spaces around their bodies, for example to represent and refer to people or things that were the topic of their questions. Another observation was the use of a question-mark sign at the beginning of yes or no questions, to call the attention of the device, while typically this sign more often used at the end of such questions. When it came to errors, such as the device not giving the result the users were looking for, most commonly users would simply ignore the error and proceed with a different command. A close second method was to repeat the command with the exact same wording and signing style, followed by rewording the command.
Using machine learning to study parenting styles
How should we raise our children? Research has shown that the amount of parental time invested is not the only crucial element for children's skill development (Del Boca et al. 2014, Attanasio et al. 2016); parenting style also matters (Fiorini and Keane 2014). Parenting style is a strategic choice linked to incentives (Doepke and Zilibotti 2014). In order to study the relationship between parenting style and child development, researchers rely on ad hoc perceptions or previous research in order to restrict the complexities of parenting to certain key actions. For instance, reading to children has been found to be highly predictive of children's skill development (Kalb and Jan van Ours 2013).
Assessing Argumentation Using Machine Learning and Cognitive Diagnostic Modeling - Research in Science Education
In this study, we developed machine learning algorithms to automatically score students' written arguments and then applied the cognitive diagnostic modeling (CDM) approach to examine students' cognitive patterns of scientific argumentation. We abstracted three types of skills (i.e., attributes) critical for successful argumentation practice: making claims, using evidence, and providing warrants. We developed 19 constructed response items, with each item requiring multiple cognitive skills. We collected responses from 932 students in Grades 5 to 8 and developed machine learning algorithmic models to automatically score their responses. We then applied CDM to analyze their cognitive patterns.
