As radiology is inherently a data-driven specialty, it is especially conducive to utilizing data processing techniques. One such technique, deep learning (DL), has become a remarkably powerful tool for image processing in recent years. In this work, the Association of University Radiologists Radiology Research Alliance Task Force on Deep Learning provides an overview of DL for the radiologist. This article aims to present an overview of DL in a manner that is understandable to radiologists; to examine past, present, and future applications; as well as to evaluate how radiologists may benefit from this remarkable new tool. We describe several areas within radiology in which DL techniques are having the most significant impact: lesion or disease detection, classification, quantification, and segmentation.

The interconnected nature of graphs often results in difficult to interpret clutter. Typically techniques focus on either decluttering by clustering nodes with similar properties or grouping edges with similar relationship. We propose using mapper, a powerful topological data analysis tool, to summarize the structure of a graph in a way that both clusters data with similar properties and preserves relationships. Typically, mapper operates on a given data by utilizing a scalar function defined on every point in the data and a cover for scalar function codomain. The output of mapper is a graph that summarize the shape of the space. In this paper, we outline how to use this mapper construction on an input graphs, outline three filter functions that capture important structures of the input graph, and provide an interface for interactively modifying the cover. To validate our approach, we conduct several case studies on synthetic and real world data sets and demonstrate how our method can give meaningful summaries for graphs with various complexities

Code-mixed data is an important challenge of natural language processing because its characteristics completely vary from the traditional structures of standard languages. In this paper, we propose a novel approach called Sentiment Analysis of Code-Mixed Text (SACMT) to classify sentences into their corresponding sentiment - positive, negative or neutral, using contrastive learning. We utilize the shared parameters of siamese networks to map the sentences of code-mixed and standard languages to a common sentiment space. Also, we introduce a basic clustering based preprocessing method to capture variations of code-mixed transliterated words. Our experiments reveal that SACMT outperforms the state-of-the-art approaches in sentiment analysis for code-mixed text by 7.6% in accuracy and 10.1% in F-score.

The exploration vs. exploitation dilemma is one of the fundamental balances in deep reinforcement learning applications. How much resources to devote to acquire knowledge that can improve future actions versus performing specific actions? This is one of the main heuristics that rule the behavior of reinforcement learning systems. In theory, optimal exploration should always conduce to more efficient knowledge but this is far from true in the real world. Developing techniques to improve the exploration of an environment is one of the pivotal challenge of the current generation of deep reinforcement learning models.

This is the final installment of a three-part series exploring the impact of artificial intelligence (AI) on investment management. I want to thank the speakers at the AI and the Future of Financial Services Forum, hosted by CFA Institute and CFA Society Beijing, for inspiring this series. The initial articles offered a primer on the AI technologies that are relevant to investment professionals and explored the potential threat AI posed to human portfolio managers. Not all is lost, investment professionals. Despite artificial intelligence (AI)'s significant and rapidly increasing "brain" power, the investment management business is not going away tomorrow.

From a couple of years, IoT has created buzz worldwide and is considered second major digital revolution. This new technology wave is going beyond smartphones, offering innovation that has made life more simplified and comfortable with the advanced level of connectivity. The future of connected cars, smart homes, connected wearables, smart cities and connected healthcare has become reality. Moreover, the growth of IoT is drastically changing how consumers interact with their cars, homes, and appliances. When we take into account, the machine-learning, machine-to-machine communication or artificial intelligence, the industrial internet of things (IIoT) leverages this innovative technology for industrial concerns to improves efficiency and productivity.

The field of multi-agent system (MAS) is an active area of research within artificial intelligence, with an increasingly important impact in industrial and other real-world applications. In a MAS, autonomous agents interact to pursue personal interests and/or to achieve common objectives. Distributed Constraint Optimization Problems (DCOPs) have emerged as a prominent agent model to govern the agents' autonomous behavior, where both algorithms and communication models are driven by the structure of the specific problem. During the last decade, several extensions to the DCOP model have been proposed to enable support of MAS in complex, real-time, and uncertain environments. This survey provides an overview of the DCOP model, offering a classification of its multiple extensions and addressing both resolution methods and applications that find a natural mapping within each class of DCOPs. The proposed classification suggests several future perspectives for DCOP extensions and identifies challenges in the design of efficient resolution algorithms, possibly through the adaptation of strategies from different areas.

Over the past two decades, technological innovations have brought significant change for organisations throughout Ireland. Through the development of the internet, the explosion in the number of mobile devices, and the emergence of the sharing economy, technology is now central to all our lives – from how we share information, access services and interact with others. And that change is accelerating. We are on the verge of a new era of digital transformation. Emerging technologies ranging from Artificial Intelligence (AI), Virtual Reality (VR) Augmented Reality (AR), cloud computing and robotics, to machine learning will revolutionise how we work, live, play, and learn.

The insurance industry has come under real pressure over the past decade or so. The fintech revolution has meant that smaller and more agile startups are able to offer a variety of new services to consumers and businesses. These services are not only more interactive and based on the latest technologies, but they are also services that bigger insurance firms cannot easily offer. This increased competition from newer market entrants is a growing problem for more established insurance providers. But with more data available to insurance firms than ever before, there is an opportunity to embrace the technological changes that are taking place.
