Skills: AI, automation changing the core nature of work, warns McKinsey Internet of Business
The average worker of the future is a socially adept leader, entrepreneur, and life-long learner with transferrable technology skills, who is also happy to work in a team, suggests a new McKinsey report. Chris Middleton looks at whether organisations can really find such people. Reports about the growing IT skills gap in digitally enhanced organisations have been circulating for as long as the internet has existed as a business tool, suggesting that the supposed urgency of fixing the problem has not been an impediment to many successful organisations. However, a new report from management consultancy McKinsey suggests that the rapid introduction of automation and artificial intelligence systems within companies is changing the very nature of work itself, as technologies increasingly augment some human skills, and replace others completely. Over the next decade, this will force companies to reconsider how work is organised internally.
The Pentagon Is Building a Dream Team of Tech-Savvy Soldiers
Nicole Camarillo was touring the Army base at Fort Meade, Maryland in early 2017 when a young captain--I'll call him Matt, due to the sensitivity of his position--crossed her path. I've got to talk to that kid, Camarillo remembers thinking. Just weeks before, she'd seen Matt deliver a presentation on a tool he was developing to counter enemy drone strikes in the Middle East. The technology, he explained, was being developed on a "shoestring budget." As executive director of talent strategy at the US Army Cyber Command, a relatively new branch of the Army, Camarillo's job is to convince top employees in Silicon Valley that they should sacrifice their stock options and six-figure salaries and apply their technological know-how in the Army instead.
How Artificial Intelligence Will Create Jobs, Improve Human Efficiency - THISDAYLIVE
Contrary to envisaged fears that emerging technology like Artificial Intelligence (AI) will put a lot of humans out of jobs, SAS, a global technology solution company has said the computerised system if well applied, will create more jobs and help improve human efficiency, using data analytics. The information on the role of AI in business growth was revealed at the SAS Road to Digital Transformation and Artificial Intelligence Workshop, which held in Lagos on Tuesday. Senior Business Solution Manager, Advanced Analytics and AI at SAS, Mr. Larry Orimoloye, argued that emerging technology like AI was actually transforming businesses creating more jobs and enhancing business efficiency. According to him, in a customer operation centre where humans are responding to customers' complaints, a lot of training and investment are being put into in to enable the staff respond accurately to customers' needs and challenges. However, he pointed out that this is something that machines like robots can easily do because they have been programmed to do so and they have the intelligence to it accurately.
Unmasking A.I.'s Bias Problem
WHEN TAY MADE HER DEBUT in March 2016, Microsoft had high hopes for the artificial intelligence–powered "social chatbot." Like the automated, text-based chat programs that many people had already encountered on e-commerce sites and in customer service conversations, Tay could answer written questions; by doing so on Twitter and other social media, she could engage with the masses. But rather than simply doling out facts, Tay was engineered to converse in a more sophisticated way--one that had an emotional dimension. She would be able to show a sense of humor, to banter with people like a friend. Her creators had even engineered her to talk like a wisecracking teenage girl. When Twitter users asked Tay who her parents were, she might respond, "Oh a team of scientists in a Microsoft lab. They're what u would call my parents." If someone asked her how her day had been, she could quip, "omg totes exhausted."
Optimality and Sub-optimality of PCA I: Spiked Random Matrix Models
Perry, Amelia, Wein, Alexander S., Bandeira, Afonso S., Moitra, Ankur
A central problem of random matrix theory is to understand the eigenvalues of spiked random matrix models, introduced by Johnstone, in which a prominent eigenvector (or "spike") is planted into a random matrix. These distributions form natural statistical models for principal component analysis (PCA) problems throughout the sciences. Baik, Ben Arous and Peche showed that the spiked Wishart ensemble exhibits a sharp phase transition asymptotically: when the spike strength is above a critical threshold, it is possible to detect the presence of a spike based on the top eigenvalue, and below the threshold the top eigenvalue provides no information. Such results form the basis of our understanding of when PCA can detect a low-rank signal in the presence of noise. However, under structural assumptions on the spike, not all information is necessarily contained in the spectrum. We study the statistical limits of tests for the presence of a spike, including non-spectral tests. Our results leverage Le Cam's notion of contiguity, and include: i) For the Gaussian Wigner ensemble, we show that PCA achieves the optimal detection threshold for certain natural priors for the spike. ii) For any non-Gaussian Wigner ensemble, PCA is sub-optimal for detection. However, an efficient variant of PCA achieves the optimal threshold (for natural priors) by pre-transforming the matrix entries. iii) For the Gaussian Wishart ensemble, the PCA threshold is optimal for positive spikes (for natural priors) but this is not always the case for negative spikes.
Wars of None: AI, Big Data, and the Future of Insurgency
Editor's Note: The rapid pace of technological innovation is changing the nature of warfare, and futurists are busy spinning out scenarios of a U.S.-China clash in twenty years involving nano-technology and fully autonomous weapons systems. Yet how will new technologies shape insurgency and counterinsurgency, which conjures up images of guerrillas hiding in Vietnam's jungles? My Brookings colleague Chris Meserole looks at two of the latest books on the subject and assesses how the balance between rebels and government may tilt. When U.S. Special Forces entered Afghanistan in 2001, Facebook didn't exist, the iPhone had yet to be invented, and "A.I." often referred to an NBA star. Seventeen years later, American special operations forces continue to ride horseback in rural Afghanistan, but information technology has advanced rapidly.
SAPPHIRE NOW: Technology and Innovation with Purpose
SAPPHIRE NOW took place on June 5-7 in Orlando with impressive numbers: more than 21,000 attendees from 102 different countries and 1,275 lectures, which was the SAP's main global event at the year. It was 3 days of much learning, where I had an opportunity to attend lectures, several demonstrations of products and applications, and meet interesting people. At the opening keynote of the event, called "The Next Move", SAP CEO Bill McDermott made the main announcements: the launch of SAP C/4 Hana and the SAP HANA Data Management Suite, the importance of SAP Leonardo, and also defined and listed what he considered the 10 main characteristics of an intelligent enterprise. McDermott commented on the importance of artificial intelligence to drive economic growth through the use of machines and the judgment of humans. "Great moments are born from great opportunities."
Pentagon's AI Surge On Track, Despite Google Protest
Google made headlines earlier this month when it pulled out of the U.S. Defense Department's flagship artificial intelligence program known as Project Maven, which leverages sophisticated algorithms to analyze drone footage. Until then, the project had been so secretive that few people knew Google was involved -- not even the former executive chairman of Google's parent company, Alphabet, who now sits on the Defense Department's Innovation Advisory Board -- let alone what it actually is. But Google's decision not to seek another contract for the AI project has thrust it into the spotlight as tech companies face a wave of protests over government contracts. "We believe that Google should not be in the business of war," more than 3,000 Google employees wrote in an April letter to company CEO Sundar Pichai that prompted the move. The growing resistance from Silicon Valley to working with the government, particularly the Pentagon, raises questions about the viability of Defense Secretary James Mattis's ambitious plans to leverage cutting-edge commercial technology for military purposes.
A Constrained Coupled Matrix-Tensor Factorization for Learning Time-evolving and Emerging Topics
Bahargam, Sanaz, Papalexakis, Evangelos E.
Topic discovery has witnessed a significant growth as a field of data mining at large. In particular, time-evolving topic discovery, where the evolution of a topic is taken into account has been instrumental in understanding the historical context of an emerging topic in a dynamic corpus. Traditionally, time-evolving topic discovery has focused on this notion of time. However, especially in settings where content is contributed by a community or a crowd, an orthogonal notion of time is the one that pertains to the level of expertise of the content creator: the more experienced the creator, the more advanced the topic. In this paper, we propose a novel time-evolving topic discovery method which, in addition to the extracted topics, is able to identify the evolution of that topic over time, as well as the level of difficulty of that topic, as it is inferred by the level of expertise of its main contributors. Our method is based on a novel formulation of Constrained Coupled Matrix-Tensor Factorization, which adopts constraints well-motivated for, and, as we demonstrate, are essential for high-quality topic discovery. We qualitatively evaluate our approach using real data from the Physics and also Programming Stack Exchange forum, and we were able to identify topics of varying levels of difficulty which can be linked to external events, such as the announcement of gravitational waves by the LIGO lab in Physics forum. We provide a quantitative evaluation of our method by conducting a user study where experts were asked to judge the coherence and quality of the extracted topics. Finally, our proposed method has implications for automatic curriculum design using the extracted topics, where the notion of the level of difficulty is necessary for the proper modeling of prerequisites and advanced concepts.
Machine Learning for Integrating Data in Biology and Medicine: Principles, Practice, and Opportunities
Zitnik, Marinka, Nguyen, Francis, Wang, Bo, Leskovec, Jure, Goldenberg, Anna, Hoffman, Michael M.
New technologies have enabled the investigation of biology and human health at an unprecedented scale and in multiple dimensions. These dimensions include myriad properties describing genome, epigenome, transcriptome, microbiome, phenotype, and lifestyle. No single data type, however, can capture the complexity of all the factors relevant to understanding a phenomenon such as a disease. Integrative methods that combine data from multiple technologies have thus emerged as critical statistical and computational approaches. The key challenge in developing such approaches is the identification of effective models to provide a comprehensive and relevant systems view. An ideal method can answer a biological or medical question, identifying important features and predicting outcomes, by harnessing heterogeneous data across several dimensions of biological variation. In this Review, we describe the principles of data integration and discuss current methods and available implementations. We provide examples of successful data integration in biology and medicine. Finally, we discuss current challenges in biomedical integrative methods and our perspective on the future development of the field.
