 Rule-Based Reasoning


Difference between Artificial Intelligence, Machine Learning and Deep Learning.

#artificialintelligence

Deep Learning is a subset of Machine Learning,which itself a subset of Artificial Intelligence. Artificial Intelligence (AI): Any algorithm or technique that allows computing devices to make decisions or solve problems that previously required humans to perform them manually can be called an AI algorithm or technique. An AI can be either a huge stack of simple if-else statements or a very complex algorithm. If you have studied Artificial Intelligence in your school or college,you would read something titled "Rule Based Systems", which is nothing but a collection of IF THEN statements,to perform a task. An example of a Rule based system is MYCIN,which is developed to identify bacteria causing severe infections and to recommend antibiotics by Stanford,which has basically nothing but IF THEN statements.


In the struggle for AI supremacy, China will prevail

Upgrade your inbox and get our Daily Dispatch and Editor's Picks. CHINA'S "Sputnik moment" came on May 27th 2017. On that day an algorithm thrashed Ke Jie, the world's best player of Go, an ancient and demanding Chinese board game. Mr Ke's defeat by AlphaGo, an artificial intelligence (AI) system developed by DeepMind, a British firm that had been bought by Google, was as much a blow to China's psyche as the Soviet satellite was to America's self-esteem in 1957. Within months, China announced ambitious plans to dominate AI by 2030. Kai-Fu Lee thinks it will succeed.


When a few simple rules are better than flashy AI

#artificialintelligence

Eager to use artificial intelligence, some companies may be unnecessarily complicating easy business problems. What's going on: Companies are over-using complex AI techniques when they would be better served with simpler approaches. Rule-based systems, for instance, show their work, thus allowing non-experts to pop the hood and see why an algorithm is misbehaving, unfair or biased.


Evolving Agents for the Hanabi 2018 CIG Competition

arXiv.org Artificial Intelligence

Abstract--Hanabi is a cooperative card game with hidden information that has won important awards in the industry and received some recent academic attention. A two-track competition of agents for the game will take place in the 2018 CIG conference. In this paper, we develop a genetic algorithm that builds rulebased agents by determining the best sequence of rules from a fixed rule set to use as strategy. In three separate experiments, we remove human assumptions regarding the ordering of rules, add new, more expressive rules to the rule set and independently evolve agents specialized at specific game sizes. As result, we achieve scores superior to previously published research for the mirror and mixed evaluation of agents. Game-playing agents have a long tradition of serving as benchmarks for AI research. However, traditionally most of the focus has been on competitive, perfect information games, such as Checkers [1], Chess [2] and Go [3]. Cooperative games with imperfect information provide an interesting research topic not only due to the added challenges posed to researchers, but also because many modern industrial and commercial applications can be characterized as examples of cooperation between humans and machines in order to achieve a mutual goal in an uncertain environment. In this paper, we address a particularly interesting cooperative game with partial information: Hanabi [4].


My experience at the SKA Big Data Africa School - Space in Africa

#artificialintelligence

I was lucky to be selected to the Square Kilometre Array Big Data Africa School funded by the SKA and the Development of Africa With Radio Astronomy (DARA). It was held in Cape Town, South Africa. Big Data is a cloudy idea. Easy to know when you have it, hard to describe. I like thinking of it as data that is sufficiently large such that it is difficult to draw information from it "easily".


Towards the Development of a Rule-based Drought Early Warning Expert Systems using Indigenous Knowledge

arXiv.org Artificial Intelligence

Abstract--Drought forecasting and prediction is a complicated process due to the complexity and scalability of the environmental parameters involved. Hence, it required a high level of expertise to predict. In this paper, we describe the research and development of a rule-based drought early warning expert systems (RB-DEWES) for forecasting drought using local indigenous knowledge obtained from domain experts. The system generates inference by using rule set and provides drought advisory information with attributed certainty factor (CF) based on the user's input. The system is believed to be the first expert system for drought forecasting to use local indigenous knowledge on drought. The architecture and components such as knowledge base, JESS inference engine and model base of the system and their functions are presented. The intricate complexity of drought has always been a stumbling block for drought forecasting and prediction systems [1]. This is mostly due to the web of environmental events (such as climate variability) that directly/indirectly triggers this environmental phenomenon. There are six broad categories of drought: meteorological, climatological, atmospheric, agricultural, hydrologic and water drought [1]. Nevertheless, irrespective of the category of drought, there is a consensus amongst scientist that drought is a disastrous condition of lack of moisture caused by a deficit in precipitation in a certain geographical region over some time period [2]. The effect of drought can be quantified based on the frequency, duration and intensity in the affected region subject to established timescales.


Using Artificial Intelligence to Support Compliance with the General Data Protection Regulation

arXiv.org Artificial Intelligence

The General Data Protection Regulation (GDPR) is a European Union regulation that will replace the existing Data Protection Directive on 25 May 2018. The most significant change is a huge increase in the maximum fine that can be levied for breaches of the regulation. Yet fewer than half of UK companies are fully aware of GDPR - and a number of those who were preparing for it stopped doing so when the Brexit vote was announced. A last-minute rush to become compliant is therefore expected, and numerous companies are starting to offer advice, checklists and consultancy on how to comply with GDPR. In such an environment, artificial intelligence technologies ought to be able to assist by providing best advice; asking all and only the relevant questions; monitoring activities; and carrying out assessments. The paper considers four areas of GDPR compliance where rule based technologies and/or machine learning techniques may be relevant: - Following compliance checklists and codes of conduct; - Supporting risk assessments; - Complying with the new regulations regarding technologies that perform automatic profiling; - Complying with the new regulations concerning recognising and reporting breaches of security. It concludes that AI technology can support each of these four areas. The requirements that GDPR (or organisations that need to comply with GDPR) state for explanation and justification of reasoning imply that rule-based approaches are likely to be more helpful than machine learning approaches. However, there may be good business reasons to take a different approach in some circumstances.


Identifying Relationships Among Sentences in Court Case Transcripts Using Discourse Relations

arXiv.org Machine Learning

Case Law has a significant impact on the proceedings of legal cases. Therefore, the information that can be obtained from previous court cases is valuable to lawyers and other legal officials when performing their duties. This paper describes a methodology of applying discourse relations between sentences when processing text documents related to the legal domain. In this study, we developed a mechanism to classify the relationships that can be observed among sentences in transcripts of United States court cases. First, we defined relationship types that can be observed between sentences in court case transcripts. Then we classified pairs of sentences according to the relationship type by combining a machine learning model and a rule-based approach. The results obtained through our system were evaluated using human judges. To the best of our knowledge, this is the first study where discourse relationships between sentences have been used to determine relationships among sentences in legal court case transcripts.


Resource-driven Substructural Defeasible Logic

arXiv.org Artificial Intelligence

Linear Logic and Defeasible Logic have been adopted to formalise different features relevant to agents: consumption of resources, and reasoning with exceptions. We propose a framework to combine sub-structural features, corresponding to the consumption of resources, with defeasibility aspects, and we discuss the design choices for the framework.


Reductive property of new fuzzy reasoning method based on distance measure

arXiv.org Artificial Intelligence

Firstly in this paper we propose a new criterion function for evaluation of the reductive property about the fuzzy reasoning result for fuzzy modus ponens and fuzzy modus tollens. Secondly unlike fuzzy reasoning methods based on the similarity measure, we propose a new fuzzy reasoning method based on distance measure. Thirdly the reductive property for 5 fuzzy reasoning methods are checked with respect to fuzzy modus ponens and fuzzy modus tollens. Through the experiment, we show that proposed method is better than the previous methods in accordance with human thinking.
