Experts search for missing mourning rings forged by eccentric philosopher Jeremy Bentham

Daily Mail

Before he died, eccentric philosopher Jeremy Bentham asked that his body be stuffed and wheeled out at parties to help his friends with their grief. But the social reformer didn't stop there, bequeathing 26 memorial rings to those he knew and admired, featuring his bust in silhouette and strands of his hair. Now scientists are on the hunt for Bentham's rings, of which just six have been found since his death in 1832. The philosopher commissioned the rings a decade before he passed, leaving them in his will and testament to a list that included famous politicians, journalists, fellow philosophers and several of his servants. Researchers say the missing artefacts could be spread across the globe, after one was found in a jewellery shop in New Orleans.

IntentsKB: A Knowledge Base of Entity-Oriented Search Intents Artificial Intelligence

We address the problem of constructing a knowledge base of entity-oriented search intents. Search intents are defined on the level of entity types, each comprising of a high-level intent category (property, website, service, or other), along with a cluster of query terms used to express that intent. These machine-readable statements can be leveraged in various applications, e.g., for generating entity cards or query recommendations. By structuring service-oriented search intents, we take one step towards making entities actionable. The main contribution of this paper is a pipeline of components we develop to construct a knowledge base of entity intents. We evaluate performance both component-wise and end-to-end, and demonstrate that our approach is able to generate high-quality data.

Clojure MXNet for musculoskeletal disease diagnosis


To get the MURA dataset you need to read and agree to the Stanford University School of Medicine MURA Dataset Research Use Agreement and register, after which you will receive a link to download the dataset. MXNet has several different data loading APIs, and I used ImageRecordIter. To do so we need to create required .rec Data needs to be organized in a specific way to use im2rec. Additionally at this point I wanted to split the provided valid part into test and val for validation during training and testing afterwards.

Management AI types with machine learning MarkTechPost


Through the assistance of machine learning, it's possible to create and manage a variety of systems. For the future of development, however, it's important that everyone can have a base knowledge of the management systems that make up artificial intelligence. In this referred article from Forbes, we will discuss some of the main management systems for most modern AI. As part of any machine learning, an artificial neural network is one of the most commonly discussed items regarding AI. This concept dates all the way back to the year 1943 in which two individuals developed a brain model for logic and mathematics.

Data-dependent Learning of Symmetric/Antisymmetric Relations for Knowledge Base Completion Machine Learning

Embedding-based methods for knowledge base completion (KBC) learn representations of entities and relations in a vector space, along with the scoring function to estimate the likelihood of relations between entities. The learnable class of scoring functions is designed to be expressive enough to cover a variety of real-world relations, but this expressive comes at the cost of an increased number of parameters. In particular, parameters in these methods are superfluous for relations that are either symmetric or antisymmetric. To mitigate this problem, we propose a new L1 regularizer for Complex Embeddings, which is one of the state-of-the-art embedding-based methods for KBC. This regularizer promotes symmetry or antisymmetry of the scoring function on a relation-by-relation basis, in accordance with the observed data. Our empirical evaluation shows that the proposed method outperforms the original Complex Embeddings and other baseline methods on the FB15k dataset.

Talla's Intelligent Knowledge Base 2.0 Full of Innovative AI Features


Talla has launched version 2.0 of the Talla Intelligent Knowledge Base -- a platform that brings together customer content with automation, chatbots, and machine learning to help customer facing teams move deals through the pipeline faster, decrease churn, and improve customer conversations. This new platform harnesses techniques in natural language processing and AI powered automation to achieve significant benefits for revenue generating teams within companies. Rob May, Founder and CEO Talla said: "Businesses today are driven by information, but the way that information is written makes it difficult to access simple crisp answers for customers. Talla uses AI to solve that problem. Our A.I. doesn't just analyze content -- it builds a knowledge graph to really understand it.

What are Expert Systems? - Moral Robots


In our continuing series on the basic concepts of Artificial Intelligence, today we take a closer look at'expert systems,' a somewhat (but not entirely) obsolete branch of symbolic AI. For a long time, expert systems were the most promising, highest-hyped products of AI research. But both the philosophical attacks by Dreyfus, Winograd and others, as well as a lingering sense of the failure of expert systems to deliver on their promises contributed to the 80's disillusionment with AI -- what has since been dubbed the "AI winter," and that ended only with the advent of deep learning in the early 2010s. Expert systems are rule-based inference machines for particular domains of knowledge. They are intended to replace "experts" in that domain.

Would you trust your medical diagnosis to a robot? You may soon get the chance to find out


There are about 10,000 known human diseases, yet human doctors are only able to recall a fraction of them at any given moment. As many as 40,500 patients die annually in an ICU in the U.S. as a result of misdiagnosis, according to a 2012 Johns Hopkins study. British entrepreneur Ali Parsa believes that artificial intelligence can help doctors avoid these mistakes. Parsa is the founder and CEO of Babylon, a U.K.-based subscription health service that plans to launch an AI-based app designed to improve doctors' hit rate. Users will report the symptoms of their illness to the app, which will check them against a database of diseases using speech recognition.

Error Detection in a Large-Scale Lexical Taxonomy Artificial Intelligence

Knowledge base (KB) is an important aspect in artificial intelligence. One significant challenge faced by KB construction is that it contains many noises, which prevents its effective usage. Even though some KB cleansing algorithms have been proposed, they focus on the structure of the knowledge graph and neglect the relation between the concepts, which could be helpful to discover wrong relations in KB. Motived by this, we measure the relation of two concepts by the distance between their corresponding instances and detect errors within the intersection of the conflicting concept sets. For efficient and effective knowledge base cleansing, we first apply a distance-based Model to determine the conflicting concept sets using two different methods. Then, we propose and analyze several algorithms on how to detect and repairing the errors based on our model, where we use hash method for an efficient way to calculate distance. Experimental results demonstrate that the proposed approaches could cleanse the knowledge bases efficiently and effectively.

Why are mosquitoes dangerous? -


We must remember that in this species it is only the females that have the benefit (bad luck for one the human being) that can sting and adsorb the blood to feed. These insects lay their eggs in wastewater. Also in ponds or in places where there is a lot of humidity. Producing in this way larvae that will later become new mosquitoes. They usually bite at times where the temperature is low such as dusk or dawn.
