Machine Learning needs tons of data. But what are you going to do when the data only exist in the heads of your employees? However, I guess I provide a good list for your next round of Artificial Intelligence (AI) bullshit bingo. If you've never heard about this term before, just read until the end and you will get its idea and importance for AI. AI Hits Puberty but Gives Enterprises a New Hope In 1955 Prof. John McCarthy already defined AI as the goal to develop machines that behave as though they were intelligent.


Association Rules and the Apriori Algorithm: A Tutorial

@machinelearnbot

When we go grocery shopping, we often have a standard list of things to buy. Each shopper has a distinctive list, depending on one's needs and preferences. A housewife might buy healthy ingredients for a family dinner, while a bachelor might buy beer and chips. Understanding these buying patterns can help to increase sales in several ways. While we may know that certain items are frequently bought together, the question is, how do we uncover these associations? Besides increasing sales profits, association rules can also be used in other fields.


Leaked Birth Control Rule Would Broaden Religious Exemption

U.S. News

But the mandate has drawn strong and sustained opposition from social conservatives, who see it as an infringement on freedom of conscience. The Obama administration exempted houses of worship, and set up a workaround for religiously affiliated nonprofits, such as hospitals, universities and social service organizations. The Supreme Court later ruled that closely held private companies were also eligible for the workaround, through which the government arranges contraceptive coverage for the affected women employees.


Building The LinkedIn Knowledge Graph

#artificialintelligence

LinkedIn's knowledge graph is a large knowledge base built upon "entities" on LinkedIn, such as members, jobs, titles, skills, companies, geographical locations, schools, etc. To solve the challenges we face when building the LinkedIn knowledge graph, we apply machine learning techniques, which is essentially a process of data standardization on user-generated content and external data sources, in which machine learning is applied to entity taxonomy construction, entity relationship inference, data representation for downstream data consumers, insight extraction from graph, and interactive data acquisition from users to validate our inference and collect training data. By mining member profiles for entity candidates and utilizing external data sources and human validations to enrich candidate attributes, we created tens of thousands of skills, titles, geographical locations, companies, certificates, etc., to which we can map members. Given the power-law nature of the member coverage of entities, linguistic experts at LinkedIn manually translate the top entities with high member coverages into international languages to achieve high precision, and PSCFG-based machine translation models are applied to automatically translate long-tail entities to achieve high recall.


Systems of natural-language-facilitated human-robot cooperation: A review

arXiv.org Artificial Intelligence

Natural-language-facilitated human-robot cooperation (NLC), in which natural language (NL) is used to share knowledge between a human and a robot for conducting intuitive human-robot cooperation (HRC), is continuously developing in the recent decade. Currently, NLC is used in several robotic domains such as manufacturing, daily assistance and health caregiving. It is necessary to summarize current NLC-based robotic systems and discuss the future developing trends, providing helpful information for future NLC research. In this review, we first analyzed the driving forces behind the NLC research. Regarding to a robot s cognition level during the cooperation, the NLC implementations then were categorized into four types {NL-based control, NL-based robot training, NL-based task execution, NL-based social companion} for comparison and discussion. Last based on our perspective and comprehensive paper review, the future research trends were discussed.


Kernel Bandwidth Selection for SVDD: Peak Criterion Approach for Large Data

arXiv.org Machine Learning

Support Vector Data Description (SVDD) provides a useful approach to construct a description of multivariate data for single-class classification and outlier detection with various practical applications. Gaussian kernel used in SVDD formulation allows flexible data description defined by observations designated as support vectors. The data boundary of such description is non-spherical and conforms to the geometric features of the data. By varying the Gaussian kernel bandwidth parameter, the SVDD-generated boundary can be made either smoother (more spherical) or tighter/jagged. The former case may lead to under-fitting, whereas the latter may result in overfitting. Peak criterion has been proposed to select an optimal value of the kernel bandwidth to strike the balance between the data boundary smoothness and its ability to capture the general geometric shape of the data. Peak criterion involves training SVDD at various values of the kernel bandwidth parameter. When training datasets are large, the time required to obtain the optimal value of the Gaussian kernel bandwidth parameter according to Peak method can become prohibitively large. This paper proposes an extension of Peak method for the case of large data. The proposed method gives good results when applied to several datasets. Two existing alternative methods of computing the Gaussian kernel bandwidth parameter (Coefficient of Variation and Distance to the Farthest Neighbor) were modified to allow comparison with the proposed method on convergence. Empirical comparison demonstrates the advantage of the proposed method.


A fuzzy expert system for earthquake prediction, case study: the Zagros range

arXiv.org Artificial Intelligence

A methodology for the development of a fuzzy expert system (FES) with application to earthquake prediction is presented. The idea is to reproduce the performance of a human expert in earthquake prediction. To do this, at the first step, rules provided by the human expert are used to generate a fuzzy rule base. These rules are then fed into an inference engine to produce a fuzzy inference system (FIS) and to infer the results. In this paper, we have used a Sugeno type fuzzy inference system to build the FES. At the next step, the adaptive network-based fuzzy inference system (ANFIS) is used to refine the FES parameters and improve its performance. The proposed framework is then employed to attain the performance of a human expert used to predict earthquakes in the Zagros area based on the idea of coupled earthquakes. While the prediction results are promising in parts of the testing set, the general performance indicates that prediction methodology based on coupled earthquakes needs more investigation and more complicated reasoning procedure to yield satisfactory predictions.

CORRECTS FROM HUTCHIS TO HUTCHINS -British IT expert Marcus Hutchins who has been branded a hero for slowing down the WannaCry global cyber attack, during an interview in Ilfracombe, England, Monday, May 15, 2017. Hutchins thwarted the virus that took computer files hostage around the world, including the British National Health computer network, telling The Associated Press he doesn't consider himself a hero but fights malware because "it's the right thing to do.''


Machine Learning with World Knowledge: The Position and Survey

arXiv.org Machine Learning

Machine learning has become pervasive in multiple domains, impacting a wide variety of applications, such as knowledge discovery and data mining, natural language processing, information retrieval, computer vision, social and health informatics, ubiquitous computing, etc. Two essential problems of machine learning are how to generate features and how to acquire labels for machines to learn. Particularly, labeling large amount of data for each domain-specific problem can be very time consuming and costly. It has become a key obstacle in making learning protocols realistic in applications. In this paper, we will discuss how to use the existing general-purpose world knowledge to enhance machine learning processes, by enriching the features or reducing the labeling work. We start from the comparison of world knowledge with domain-specific knowledge, and then introduce three key problems in using world knowledge in learning processes, i.e., explicit and implicit feature representation, inference for knowledge linking and disambiguation, and learning with direct or indirect supervision. Finally we discuss the future directions of this research topic.


Technical Perspective: Building Knowledge Bases from Messy Data

Communications of the ACM

Imagine the task of creating a database of all the high-quality specialty cafés around the world so you never have to settle for an imperfect brew. Relying on reviews from sites such as Yelp will not do the job because there is no restriction on who can post reviews there. You, on the other hand, are interested only in cafés that are reviewed by the coffee intelligentsia. There are several online sources with content relevant to your envisioned database. Cafés may be featured in well-respected coffee publications such as sprudge.com
