How project managers are essential to AI deployment

#artificialintelligence

Artificial intelligence (AI) and machine learning are crucial to modern-day business success, which is why nearly 60% of organizations have deployed AI, according to Gartner's recent Survey Analysis: AI and ML Development Strategies, Motivators and Adoption Challenges. AI projects are predicted to grow, resulting in an increase in AI staffing numbers in the next three years, KPMG's AI Transforming the Enterprise report added. However, the number of AI-specific employees aren't the only ones expected increase, PMI's Pulse of the Profession survey reported on Thursday. As the number of AI projects increase, so do the number of individuals managing those projects: Over the next three years, 27% of respondents said AI will lead to the creation of more project management jobs. "While there's a fear that AI will replace jobs, AI has – and will continue – to open up opportunities for project managers," said Mike DePrisco, PMI's vice president of global solutions.


Google open-sources datasets for AI assistants with human-level understanding

#artificialintelligence

Both datasets are being shared by Google AI researchers to supply the training material necessary to model natural language systems that achieve human-level performance. Google researchers call CCPE a new way to collect voice data. It includes 500 dialogues with people about their movie preferences -- 10,000 in total, across 12,000 utterances. Movie preferences were chosen as a topic because of the value of metadata such as the names of actors and directors. "We do not restrict the workers to detailed scripts or to a small knowledge base and hence we observe that our dataset contains more realistic and diverse conversations in comparison to existing datasets," a paper published covering CCPE reads.


Artificial Intelligent Solutions

#artificialintelligence

Artificial Intelligence is machine intelligence or ability to think and process information like natural human intelligence in order to create expert systems with human intelligence (reasoning, learning, and problem solving) with help from science and technology disciplines such as Mathematics, Engineering, Biology, Computer Science, Linguistics and Psychology. The term intelligence, literally, means the ability to acquire and apply knowledge and skills. The term Artificial Intelligence ( Artificial Intelligence) is pretty self-explanatory. It is the ability to acquire and apply knowledge and skills artificially. In 1956, a group of researchers from different disciplines of technology gathered for the summit called Dartmouth Summer Research Project.


Fault diagnosis in machine tools using selective regional correlation

#artificialintelligence

ABSTRACT: This paper investigates the detection and diagnosis of brush seizing faults in the spindle positioning servo drive of a high-precision machining centre using a recently developed time–frequency pattern classification technique known as selective regional correlation (SRC). It is shown that SRC is capable of significantly enhancing the resolution of fault diagnosis when compared to conventional correlation-based techniques. The performance of this approach is evaluated using three time–frequency transformation techniques: the short-time Fourier transform (STFT), continuous wavelet transform (CWT) and S-Transform. In addition, three different 2D windows are used to isolate features for use with SRC: a rectangular (boxcar) window, a Gaussian window and a Kaiser window. The results have indicated that SRC is a promising tool for machine condition monitoring (MCM).


As homomorphic encryption gains steam, experts search for standards - CyberScoop

#artificialintelligence

Encryption has always been a battle line in cyberspace. Attackers try to break it; defenders reinforce it. The next front in that struggle is something known as homomorphic encryption, which scrambles data not just when it is at rest or in transit, but when it is being used. The idea is to not have to decrypt sensitive financial or healthcare data, for example, in order to run computations with it. Defenders are trying to get ahead of attackers by locking down data wherever it lies.


An Expert System Approach for determine the stage of UiTM Perlis Palapes Cadet Performance and Ranking Selection

arXiv.org Artificial Intelligence

The palapes cadets are one of the uniform organizations in UiTM Perlis for extra-curricular activities. The palapes cadets arrange their organization in a hierarchy according to grade. Senior uniform officer (SUO) is the highest rank, followed by a junior uniform officer (JUO), sergeant, corporal, lance corporal, and lastly, cadet officer, which is the lowest rank. The palapes organization has several methods to measure performance toward promotion to a higher rank, whether individual performance or in a group. Cadets are selected for promotion based on demonstrated leadership abilities, acquired skills, physical fitness, and comprehension of information as measured through standardized testing. However, this method is too complicated when manually assessed by a trainer or coach. Therefore, this study will propose an expert system, which is one of the artificial intelligence techniques that can recognize the readiness and progression of a palapes cadet.


HyperKG: Hyperbolic Knowledge Graph Embeddings for Knowledge Base Completion

arXiv.org Artificial Intelligence

Learning embeddings of entities and relations existing in knowledge bases allows the discovery of hidden patterns in data. In this work, we examine the geometrical space's contribution to the task of knowledge base completion. We focus on the family of translational models, whose performance has been lagging, and propose a model, dubbed HyperKG, which exploits the hyperbolic space in order to better reflect the topological properties of knowledge bases. We investigate the type of regularities that our model can capture and we show that it is a prominent candidate for effectively representing a subset of Datalog rules. We empirically show, using a variety of link prediction datasets, that hyperbolic space allows to narrow down significantly the performance gap between translational and bilinear models.


A Guide to Rules Engines for IoT: Forward-Chaining Engines - DZone IoT

#artificialintelligence

An inference engine using forward chaining applies a set of rules and facts to deduce conclusions, searching the rules until it finds one where the IF clause is known to be true. The process of matching new or existing facts against rules is called pattern matching, which forward chaining inference engines perform through various algorithms, such as Linear, Rete, Treat, Leaps, etc. When a condition is found to be TRUE, the engine executes the THEN clause, which results in new information being added to its dataset. In other words, the engine starts with a number of facts and applies rules to derive all possible conclusions from those facts. This is where the name "forward chaining" comes from -- the fact that the inference engine starts with the data and reasons its way forward to the answer, as opposed to backward chaining, which works the other way around.


The Terminology of Artificial Intelligence Part 2

#artificialintelligence

Professor Edward Feigenbaum, while explaining the meaning of Al to a distinguished and perplexed scientific review panel for a Department of Defense AI application development program in the late 1970s commented, "If it works, it isn't AI." Because AI has been a subject of considerable interest, a number of suppliers and developers of software products have embraced the technology and offer products or demonstrations that "contain AI" It is possible that some of this labeling might be controversial among those who have worked in the field for some time. Since most AI appears as a software of some sort, many practitioners of conventional software development can recognize aspects of AI programs that could be accomplished with conventional technology. An industrial engineer replaced an electromechanical controller on a large machine with an electronic controller which included a CRT display. Upon being told the rudimentary aspects of AI technology, the industrial engineer suddenly exclaimed, "Wow, I've been doing AI all along!"


The Impact of Feature Causality on Normal Behaviour Models for SCADA-based Wind Turbine Fault Detection

arXiv.org Machine Learning

The cost of wind energy can be reduced by using SCADA data to detect faults in wind turbine components. Normal behavior models are one of the main fault detection approaches, but there is a lack of consensus in how different input features affect the results. In this work, a new taxonomy based on the causal relations between the input features and the target is presented. Based on this taxonomy, the impact of different input feature configurations on the modelling and fault detection performance is evaluated. To this end, a framework that formulates the detection of faults as a classification problem is also presented.
