Information Technology: Overviews


Best NLP Research of 2019

#artificialintelligence

Natural language processing (NLP) is one of the most important technologies to arise in recent years. Specifically, 2019 has been a big year for NLP with the introduction of the revolutionary BERT language representation model. There are a large variety of underlying tasks and machine learning models powering NLP applications. Recently, deep learning approaches have obtained very high performance across many different NLP tasks. Convolutional Neural Network (CNNs) are typically associated with computer vision, but more recently CNNs have been applied to problems in NLP.


How Artificial Intelligence is transforming the education system

#artificialintelligence

From machine learning to smart sensors, today, social as well as economic ecosystems are surrounded by the dynamics of Artificial Intelligence (AI). Furthermore, the presence of robotics is perceived as a powerful catalyst for industrial productivity and economic growth. Artificial Intelligence in association with the other path-breaking technologies of the present times is increasing the efficiency of people as well as machines in every sector, and prominently in the education sector. Today, Artificial Intelligence has already made long strides in the academic world, transforming the traditional methods of imparting knowledge into a comprehensive system of learning using simulation and augmented reality (AR) tools. Interactive study material comprising text as well as media files can be shared very easily among the interest groups and with the help of smart devices, they can utilise the study material rather effectively as per their convenience.


How AI and machine learning are transforming clinical decision support

#artificialintelligence

"Between 12 to 18 million Americans every year will experience some sort of diagnostic error," said Paul Cerrato, a journalist and researcher. "So the question is: Why such a huge number? And what can we do better in terms of reinventing the tools so they catch these conditions more effectively?" Cerrato is co-author, alongside Dr. John Halamka, newly minted president of Mayo Clinic Platform, of the new HIMSS Book Series edition, Reinventing Clinical Decision Support: Data Analytics, Artificial Intelligence, and Diagnostic Reasoning. At HIMSS20, the two of them will discuss the book, and the bigger picture around CDS tools that are fast being transformed by the advent of artificial intelligence, machine learning and big data analytics.


12 Supervised Learning Modern Statistics for Modern Biology

#artificialintelligence

In a supervised learning setting, we have a yardstick or plumbline to judge how well we are doing: the response itself. A frequent question in biological and biomedical applications is whether a property of interest (say, disease type, cell type, the prognosis of a patient) can be "predicted", given one or more other properties, called the predictors. Often we are motivated by a situation in which the property to be predicted is unknown (it lies in the future, or is hard to measure), while the predictors are known. The crucial point is that we learn the prediction rule from a set of training data in which the property of interest is also known. Once we have the rule, we can either apply it to new data, and make actual predictions of unknown outcomes; or we can dissect the rule with the aim of better understanding the underlying biology. Compared to unsupervised learning and what we have seen in Chapters 5, 7 and 9, where we do not know what we are looking for or how to decide whether our result is "right", we are on much more solid ground with supervised learning: the objective is clearly stated, and there are straightforward criteria to measure how well we are doing. The central issues in supervised learning151151 Sometimes the term statistical learning is used, more or less exchangeably. Or did our rule indeed pick up some of the pertinent patterns in the system being studied, which will also apply to yet unseen new data? An example for overfitting: two regression lines are fit to data in the \((x, y)\)-plane (black points). We can think of such a line as a rule that predicts the \(y\)-value, given an \(x\)-value. Both lines are smooth, but the fits differ in what is called their bandwidth, which intuitively can be interpreted their stiffness. The blue line seems overly keen to follow minor wiggles in the data, while the orange line captures the general trend but is less detailed. The effective number of parameters needed to describe the blue line is much higher than for the orange line. Also, if we were to obtain additional data, it is likely that the blue line would do a worse job than the orange line in modeling the new data. We'll formalize these concepts –training error and test set error– later in this chapter. Although exemplified here with line fitting, the concept applies more generally to prediction models. See exemplary applications that motivate the use of supervised learning methods.


A Decade Of Change: How Tech Evolved In The 2010s And What's In Store For The 2020s

#artificialintelligence

Significant technological advancements and societal shifts occurred during the 2010's decade. Yet many of these developments became so quickly engrained in our daily lives that they often went relatively unnoticed, and their impact all but forgotten. Over this next decade, the 2020s, we expect similar rapid and meaningful advancements to occur. Moore's law suggests that over a 10-year period, semiconductors will advance by 32 times, bringing about mesmerizing innovation in the digital age that should not only change technology but society as well. In this piece, we review the technological advancements over the last decade and anticipate what revolutionary changes may be in store for us over the next 10 years.


An introduction to time series forecasting Algorithmia Blog

#artificialintelligence

Despite its almost ubiquitous use in the business industry and social sciences, time series analysis and by extension time series forecasting is one of the least understood machine learning methods new data scientists and machine learning engineers are undertaking. The purpose of this blog is to provide an overview of this lesser-known but incredibly important machine learning technique. To answer this question, let's take a step back to discuss the types of data that we use for typical regression and classification tasks. When we make a prediction about a new observation, that model is built from hundreds or thousands of previous observations that are either all captured at a single point in time, or from data points in which time does not matter. This is known as cross-sectional data.

Survey Report: How To Engage Machine Learning Developers

#artificialintelligence

A lot of organizations seek to engage closely with ML developers, either to increasing product adoption or crowdsource innovation. But a lot of these efforts fall into the trap of "seen-it-done-it-all" trap, where organizations employ the same strategies to engage them which they have utilized for other developers. Machine Learning developers have unique needs from the ecosystem. They face challenges that developers from another stream are largely insulated from. Firstly, ML is a fast-changing domain.


A road map for artificial intelligence policy

#artificialintelligence

The rapid development of artificial intelligence technologies around the globe has led to increasing calls for robust AI policy: laws that let innovation flourish while protecting people from privacy violations, exploitive surveillance, biased algorithms, and more. But the drafting and passing of such laws has been anything but easy. "This is a very complex problem," Luis Videgaray PhD '98, director of MIT's AI Policy for the World Project, said in a lecture on Wednesday afternoon. "This is not something that will be solved in a single report. This has got to be a collective conversation, and it will take a while. It will be years in the making."
