HR Tech is Transforming Workplace Management Norms
With a changing workforce, the enterprise workspace is also undergoing a distinct change, aided by the HR technology available today. Trends such as mobility, flexibility, and cognitive computing are forcing organizations to rethink the ways of workplace management. Not only are HRMS changing talent management practices, but they are also helping revolutionize organizational designs. New office ergonomics and new policies and practices are sweeping across the modern organization. The boundaries between HR and technology are blurring, and innovative means for workforce management (WFM) are taking to the mainstream.
5 Free Statistics eBooks You Need to Read This Autumn
Did you have a good, relaxing break over the summer? Are you refreshed and re-energised, looking forward to a new start, a new you and brushing up on your data analysis skills? If so, I've thrown together a collection of a few excellent (and free!) statistics eBooks for your Kindle to sharpen up your stats while you're on the long commute to work. Just try not to read them while driving! These books require different levels of existing knowledge, and while some are for early-stage data scientists others are for more hard-core physicists and mathematicians.
A Deep Causal Inference Approach to Measuring the Effects of Forming Group Loans in Online Non-profit Microfinance Platform
Kiva is an online non-profit crowdsouring microfinance platform that raises funds for the poor in the third world. The borrowers on Kiva are small business owners and individuals in urgent need of money. To raise funds as fast as possible, they have the option to form groups and post loan requests in the name of their groups. While it is generally believed that group loans pose less risk for investors than individual loans do, we study whether this is the case in a philanthropic online marketplace. In particular, we measure the effect of group loans on funding time while controlling for the loan sizes and other factors. Because loan descriptions (in the form of texts) play an important role in lenders' decision process on Kiva, we make use of this information through deep learning in natural language processing. In this aspect, this is the first paper that uses one of the most advanced deep learning techniques to deal with unstructured data in a way that can take advantage of its superior prediction power to answer causal questions. We find that on average, forming group loans speeds up the funding time by about 3.3 days.
Forward Thinking: Building and Training Neural Networks One Layer at a Time
Hettinger, Chris, Christensen, Tanner, Ehlert, Ben, Humpherys, Jeffrey, Jarvis, Tyler, Wade, Sean
We present a general framework for training deep neural networks without backpropagation. This substantially decreases training time and also allows for construction of deep networks with many sorts of learners, including networks whose layers are defined by functions that are not easily differentiated, like decision trees. The main idea is that layers can be trained one at a time, and once they are trained, the input data are mapped forward through the layer to create a new learning problem. The process is repeated, transforming the data through multiple layers, one at a time, rendering a new data set, which is expected to be better behaved, and on which a final output layer can achieve good performance. We call this forward thinking and demonstrate a proof of concept by achieving state-of-the-art accuracy on the MNIST dataset for convolutional neural networks. We also provide a general mathematical formulation of forward thinking that allows for other types of deep learning problems to be considered.
Meta Networks
Munkhdalai, Tsendsuren, Yu, Hong
Neural networks have been successfully applied in applications with a large amount of labeled data. However, the task of rapid generalization on new concepts with small training data while preserving performances on previously learned ones still presents a significant challenge to neural network models. In this work, we introduce a novel meta learning method, Meta Networks (MetaNet), that learns a meta-level knowledge across tasks and shifts its inductive biases via fast parameterization for rapid generalization. When evaluated on Omniglot and Mini-ImageNet benchmarks, our MetaNet models achieve a near human-level performance and outperform the baseline approaches by up to 6% accuracy. We demonstrate several appealing properties of MetaNet relating to generalization and continual learning.
A budget-constrained inverse classification framework for smooth classifiers
Lash, Michael T., Lin, Qihang, Street, W. Nick, Robinson, Jennifer G.
Inverse classification is the process of manipulating an instance such that it is more likely to conform to a specific class. Past methods that address such a problem have shortcomings. Greedy methods make changes that are overly radical, often relying on data that is strictly discrete. Other methods rely on certain data points, the presence of which cannot be guaranteed. In this paper we propose a general framework and method that overcomes these and other limitations. The formulation of our method can use any differentiable classification function. We demonstrate the method by using logistic regression and Gaussian kernel SVMs. We constrain the inverse classification to occur on features that can actually be changed, each of which incurs an individual cost. We further subject such changes to fall within a certain level of cumulative change (budget). Our framework can also accommodate the estimation of (indirectly changeable) features whose values change as a consequence of actions taken. Furthermore, we propose two methods for specifying feature-value ranges that result in different algorithmic behavior. We apply our method, and a proposed sensitivity analysis-based benchmark method, to two freely available datasets: Student Performance from the UCI Machine Learning Repository and a real world cardiovascular disease dataset. The results obtained demonstrate the validity and benefits of our framework and method.

Sesame Workshop and IBM team up to test a new A.I.-powered teaching method
Can A.I. help build better educational apps for kids? That's a question Sesame Workshop, the nonprofit organization behind the popular children's TV program "Sesame Street" and others, aims to answer. The company has teamed up with IBM to create the first vocabulary learning app powered by IBM's A.I., which adapts itself the child's current reading level and vocabulary range, then continues to intelligently adjust as the child's vocabulary skills improve. IBM and Sesame Workshop announced last year that the two companies would work together on a line of cognitive apps, games and educational toys. This new app is the first result of that three-year partnership. The companies have now just completed a pilot trial for the app, where it was introduced to over 150 students in Georgia's Gwinnett County Public Schools.

AI Influencer Andrew Ng Plans The Next Stage In His Extraordinary Career
Andrew Ng is one of the foremost thinkers on the topic of artificial intelligence. He founded and led the "Google Brain" project which developed massive-scale deep learning algorithms. In 2011, he led the development of Stanford University's main Massive Open Online Course (MOOC) platform. His course on Machine Learning would eventually reach an "enrollment" of over 100,000 students. That experience led Ng to co-found Coursera, a MOOC that partners with some of the top universities in the world to offer high quality online courses. Today, Coursera is the largest MOOC platform in the world.
