'Child's Play' reboot trailer suggests Chucky is now a killer robot
It's not completely impossible that robots could turn against us, so it's no surprise killer robot movies have been popular for decades. We could be about to add another flick to the canon, as the new trailer for the Child's Play reboot suggests. Plot details haven't been confirmed yet, so it's not totally certain this Chucky is a robot, but there's enough to back up rumors it's a defective doll "whose programming code was hacked so that he has no limitations to learning and also violence." The evidence in the trailer is pretty conclusive. It opens up like an ad for a big tech company, before showing some moving metal parts amid some familiar-looking clothing and a kid getting his face scanned after unwrapping a certain doll (which you don't get a good look at here, unfortunately).
The cold start problem: how to build your machine learning portfolio
I'm a physicist who works at a YC startup. Our job is to help new grads get hired into their first machine learning jobs. Some time ago, I wrote about the things you should do to get hired into your first machine learning job. I said in that post that one thing you should do is build a portfolio of your personal machine learning projects. But I left out the part about how to actually to do that, so in this post, I'll tell you how.
City of Otsu to use AI to analyze past school bullying cases with an eye on future prevention
"Through an AI theoretical analysis of past data, we will be able to properly respond to cases without just relying on teachers' past experiences," Otsu Mayor Naomi Koshi said of the planned analysis, set to begin from the next fiscal year. AI will be used to analyze 9,000 suspected bullying cases reported by elementary and junior high schools in the city over the six years through fiscal 2018. It will examine the school grade and gender of the suspected victims and perpetrators as well as when and where the incidents occurred. Statistical analysis of the data is expected to help local authorities and teachers identify forms of bullying that tend to escalate in seriousness and which therefore require extra attention, the Otsu board of education said. The AI analysis will also look at other factors, such as school absenteeism and academic achievement, and the findings will be compiled into a report for use by teachers and in training seminars.
Machine Learning to Promote People Learning
Artificial intelligence is a buzzy phrase that seems to be permeating every industry, from finance to health care to education. Learning and development leaders, for example, are likely asking themselves, "How will this affect learning? What opportunities are there and what is the role AI will play?" Ready or not, it seems that AI has made its way into L&D and the time to act is now. With the increasing pace of technological changes, L&D leaders need to modify their approaches accordingly.
Accenture Joins Forces with MIT Professional Education to Reinvent Their Quality Engineering Workforce
Accenture Joins Forces with MIT Professional Education to Reinvent Their Quality Engineering Workforce Quality engineers are being trained to be catalysts for speed, agility and improved business performance NEW YORK; Jan. 29, 2019 โ Accenture (NYSE: ACN) is collaborating with MIT Professional Education to launch a new training program aimed at training the company's quality engineers pivot from being software testers to catalysts for speed, agility and business performance. The program, 'Reinventing Quality Engineers in the New,' will train Accenture employees on real-time, insight-driven quality engineering approaches, augmented by artificial intelligence, analytics and autonomous frameworks--a vision outlined in a recent Accenture whitepaper. The jointly developed program provides Accenture engineers with opportunities to grow their skill set in ways that enhance both their own careers and Accenture's work with clients. Employees will learn how to effectively apply analytics and intelligent, model-based automation to software testing and engineering services, as well as advanced risk-based testing approaches that optimize cost and quality levels. The program consists of live virtual classroom sessions that include engagement with MIT professors, as well as self-study materials and opportunities to collaborate outside of the classroom through interactive online forums.
Meta-Curvature
Park, Eunbyung, Oliva, Junier B.
We propose to learn curvature information for better generalization and fast model adaptation, called meta-curvature. Based on the model-agnostic meta-learner (MAML), we learn to transform the gradients in the inner optimization such that the transformed gradients achieve better generalization performance to a new task. For training large scale neural networks, we decompose the curvature matrix into smaller matrices and capture the dependencies of the model's parameters with a series of tensor products. We demonstrate the effects of our proposed method on both few-shot image classification and few-shot reinforcement learning tasks. Experimental results show consistent improvements on classification tasks and promising results on reinforcement learning tasks. Furthermore, we observe faster convergence rates of the meta-training process. Finally, we present an analysis that explains better generalization performance with the meta-trained curvature.
Collaboration based Multi-Label Learning
It is well-known that exploiting label correlations is crucially important to multi-label learning. Most of the existing approaches take label correlations as prior knowledge, which may not correctly characterize the real relationships among labels. Besides, label correlations are normally used to regularize the hypothesis space, while the final predictions are not explicitly correlated. In this paper, we suggest that for each individual label, the final prediction involves the collaboration between its own prediction and the predictions of other labels. Based on this assumption, we first propose a novel method to learn the label correlations via sparse reconstruction in the label space. Then, by seamlessly integrating the learned label correlations into model training, we propose a novel multi-label learning approach that aims to explicitly account for the correlated predictions of labels while training the desired model simultaneously. Extensive experimental results show that our approach outperforms the state-of-the-art counterparts.
A Smoother Way to Train Structured Prediction Models
Pillutla, Krishna, Roulet, Vincent, Kakade, Sham M., Harchaoui, Zaid
We present a framework to train a structured prediction model by performing smoothing on the inference algorithm it builds upon. Smoothing overcomes the non-smoothness inherent to the maximum margin structured prediction objective, and paves the way for the use of fast primal gradient-based optimization algorithms. We illustrate the proposed framework by developing a novel primal incremental optimization algorithm for the structural support vector machine. The proposed algorithm blends an extrapolation scheme for acceleration and an adaptive smoothing scheme and builds upon the stochastic variance-reduced gradient algorithm. We establish its worst-case global complexity bound and study several practical variants, including extensions to deep structured prediction. We present experimental results on two real-world problems, namely named entity recognition and visual object localization. The experimental results show that the proposed framework allows us to build upon efficient inference algorithms to develop large-scale optimization algorithms for structured prediction which can achieve competitive performance on the two real-world problems.
Using AI to Build Systems that Support and Engage Adult Learners
Today, nearly 40 percent of students at U.S. colleges are age 25 or older. They often work at least part time to afford tuition and living costs, and many are juggling school and family responsibilities like caring for children. Time is a precious resource for them. These "nontraditional" students require flexibility so that they can accommodate all their responsibilities while pursuing their higher education. As the demand for more flexibility grows, so does the demand for online learning.
