Joint Event and Temporal Relation Extraction with Shared Representations and Structured Prediction

arXiv.org Artificial Intelligence

The task can be modeled as building a graph for a given text, whose nodes represent events and edges are labeled with temporal relations correspondingly. Figure 1a illustrates such a graph for the text shown therein. The nodes assassination, slaughtered, rampage, war, and Hutu are the candidate events, and different types of edges specify different temporal relations between them: assassination is BEFORE rampage, rampage INCLUDES slaughtered, and the relation between slaughtered and war is VAGUE. Since "Hutu" is actually not an event, a system is expected to annotate the relations between "Hutu" and all other nodes in the graph as NONE (i.e., no relation). As far as we know, all existing systems treat this task as a pipeline of two separate subtasks, (a) Temporal Relation Graph (b) Pipeline Model (c) Structured Joint Model Figure 1: An illustration of event and relation models in our proposed joint framework.


The four drivers of Artificial Intelligence

#artificialintelligence

An updated version of Marc Andreessen's famous quote, "Software is eating the world" probably is "AI is eating software." We tend to think of AI in incremental ways, and we need to urgently change that thought process because our approach to AI will demarcate the difference between linear thinking and transformational thinking. Most organizations want to use AI to cut costs and do the thing they are already doing faster and quicker; this is an incremental approach to AI, whereas we need to focus on the next-level use of AI, that exponentially transforms the way we have been doing things thus far by creating new systems. For example, Amazon Go (Amazon's retail store) isn't using AI to simply remove the role of the cashier, but it is designing a new retail experience that is data and information-driven. Thus, instead of simply putting a layer of AI on top of existing processes, Amazon Go is changing the average grocery-shopping exercise into an experience-driven activity that is all about data, understanding people, behavior and design layout. Similarly, the objective of driverless autonomous vehicles is not merely to eliminate the cost of the driver, but to change the way we travel and redesign the entire transportation industry as well as create ripple effects in the e-commerce and delivery industries.


3 Technologies That Transform Insurance - Insurance Thought Leadership

#artificialintelligence

The combination of AI, robotic processing automation and predictive data analytics is redefining how businesses operate. The combination of artificial intelligence (AI), robotic processing automation and predictive data analytics is fundamentally redefining how businesses operate, how consumers engage with brands and, indeed, how we go about our daily lives. The field of insurance is no exception. Outlined here are three ways smart technology is affecting insurance, with a focus on identifying lessons learned and defining specific keys to success. The impact of rules-based robotic process automation (RPA) on insurance operations has been well-documented.


SAERMA: Stacked Autoencoder Rule Mining Algorithm for the Interpretation of Epistatic Interactions in GWAS for Extreme Obesity

arXiv.org Machine Learning

One of the most important challenges in the analysis of high-throughput genetic data is the development of efficient computational methods to identify statistically significant Single Nucleotide Polymorphisms (SNPs). Genome-wide association studies (GWAS) use single-locus analysis where each SNP is independently tested for association with phenotypes. The limitation with this approach, however, is its inability to explain genetic variation in complex diseases. Alternative approaches are required to model the intricate relationships between SNPs. Our proposed approach extends GWAS by combining deep learning stacked autoencoders (SAEs) and association rule mining (ARM) to identify epistatic interactions between SNPs. Following traditional GWAS quality control and association analysis, the most significant SNPs are selected and used in the subsequent analysis to investigate epistasis. SAERMA controls the classification results produced in the final fully connected multi-layer feedforward artificial neural network (MLP) by manipulating the interestingness measures, support and confidence, in the rule generation process. The best classification results were achieved with 204 SNPs compressed to 100 units (77% AUC, 77% SE, 68% SP, 53% Gini, logloss=0.58, and MSE=0.20), although it was possible to achieve 73% AUC (77% SE, 63% SP, 45% Gini, logloss=0.62, and MSE=0.21) with 50 hidden units - both supported by close model interpretation.


How Artificial Intelligence Will Solve IoT's Big Data Challenges

#artificialintelligence

If IoT is going to deliver on its transformational promise, it will have to provide greater value and importance than a single internet enabled sensor such as a wearable device. The technology to create a central hub around a small collection of sensors, for example in home automation, has been around for decades. What is revolutionary today is that home automation is cheaper to implement and gives home owners better software to monitor and control their homes remotely. As I've said in a previous post, the real magic happens when a hub of managed sensors can easily communicate with other neighboring systems. Each hub has to be programmed to intelligently broadcast signals to its neighbors and also make intelligent decisions on how to process signals from its neighbors.


Overview of the enterprise AI market

As per the market analysis in 2018 enterprise AI market is valued at 1211.60 million USD. The market is expected to grow to 15042.32 million by 2024 as end users are seeing immense potential in process automation. The operational efficiency has grown in organisations that have implemented artificial intelligence. This has also resulted in running businesses in an extremely cost-efficient way. Organisations are always up for reducing their operational costs and do regular work more efficiently. They're always behind catching up with cutting edge technologies as the nature of technology has always been to bring more power to the system and make tasks less tedious.


Building Ethically Aligned AI Systems - IBM Research Blog

#artificialintelligence

The more AI agents are deployed in scenarios with possibly unexpected situations, the more they need to be flexible, adaptive, and creative in achieving their goals. Thus, a certain level of freedom to choose the best path to a specific goal is necessary in making AI robust and flexible enough to be deployed successfully in real-life scenarios. This is especially true when AI systems tackle difficult problems whose solution cannot be accurately defined by a traditional rule-based approach but require the data-driven and/or learning approaches increasingly being used in AI. Indeed, data-driven AI systems, such as those using machine learning, are very successful in terms of accuracy and flexibility, and they can be very "creative" in solving a problem, finding solutions that could positively surprise humans and teach them innovative ways to resolve a challenge. However, creativity and freedom without boundaries can sometimes lead to undesired actions: the AI system could achieve its goal in ways that are not considered acceptable according to values and norms of the impacted community.


Artificial intelligence and machine learning are the next frontiers for ETFs, says industry pro

#artificialintelligence

Artificial intelligence and machine learning could be the next frontier for ETFs to outperform the market. So says Robert Tull, President of ProcureAM, an innovative exchange-traded product firm and wholly owned subsidiary of Procure Holdings. A veteran in the business, Tull has been involved in the ETF industry for decades, creating more than 400 ETFs across 18 different countries. Now, he's looking at new ways to beat the market by using big data as raw material, combined with machine learning, to build ETF portfolios that could potentially outperform active management -- even actively managed ETFs. "Active management has been out there for a long time, underperforming," he said on CNBC's "ETF Edge." "They haven't found a solution yet, and I think the technology that I've run into is going to help the marketplace today."


Rule Based System

#artificialintelligence

Every rule based system contains four basic components. Firstly, the system contains a set of rules, also known as the rule base, and acts as the domain of knowledge for the computer. Second, there is an interference engine, also called the semantic reasoner. This component is responsible for interpretation of the rules and taking action accordingly. The interference engine works in three steps: match, conflict-resolution, and act.


Preventing the Generation of Inconsistent Sets of Classification Rules

arXiv.org Artificial Intelligence

--In recent years, the interest in interpretable classification models has grown. One of the proposed ways to improve the interpretability of a rule-based classification model is to use sets (unordered collections) of rules, instead of lists (ordered collections) of rules. One of the problems associated with sets is that multiple rules may cover a single instance, but predict different classes for it, thus requiring a conflict resolution strategy. In this work, we propose two algorithms capable of finding feature-space regions inside which any created rule would be consistent with the already existing rules, preventing inconsistencies from arising. Our algorithms do not generate classification models, but are instead meant to enhance algorithms that do so, such as Learning Classifier Systems. Both algorithms are described and analyzed exclusively from a theoretical perspective, since we have not modified a model-generating algorithm to incorporate our proposed solutions yet. This work presents the novelty of using conflict avoidance strategies instead of conflict resolution strategies.
