"An ontology defines the terms used to describe and represent an area of knowledge. … Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them."

Instead of seeing each Machine Learning (ML) method as a "shiny new object", here is an attempt to create a unified picture. There is no consensus when it comes to an ontology for ML methods; organizational principles are simply ways to get our arms around knowledge so that we are not swamped by too many unconnected notions. In chapter 4 ("Modern" ML Method) of my upcoming book, "SYSTEMS Analytics", we develop the basic theory and algorithms for some key blocks in the diagram above. In ML practice, these ML methods are "wrapped" by "bootstrap" and "consensus" methods.
CORALVILLE, Iowa--(BUSINESS WIRE)--Cognonto, a new start-up in knowledge-based artificial intelligence (KBAI), announced today the dual release of its Cognonto Platform and KBpedia, a computable knowledge structure to automate much of the effort needed for machine learning. KBpedia leverages six large-scale knowledge bases -- Wikipedia, Wikidata, GeoNames, OpenCyc, DBpedia and UMBEL -- into a single structure expressly designed to support artificial intelligence (AI) within enterprises. He noted the Cognonto Platform also leverages KBpedia to map and integrate enterprise content to tailor the machine learning. Giasson said typical uses include fine-grained entity extraction, categorizing content, and enterprise information integration.
Unsupervised machine learning methods require feeding large amounts of various kinds of data on features of a subject matter. After all, by Google's own admission, their open source Natural Language Understanding (NLU) system called SyntaxNet has just over a 90 percent accuracy rate. In "Don't do what I say, do what I mean," I articulated how the banking industry is using ontologies to develop knowledge models to describe business concepts and features to mitigate global risks. Ontologies are not a replacement for machine learning methods, but a pillar for another type of machine learning called supervised machine learning.
Paul Horn, then director of IBM Research, had been bugging Lickel to come up with an idea for the company's next "grand challenge," Big Blue's tradition of tackling incredibly tough problems just to see if they can be solved. In the beginning, the researchers experimented with rule based systems, similar to Doug Lenat's Cyc project that would answer questions based on information provided by human experts, almost the way an encyclopedia works. But where the company really sees great opportunity is by offering Watson as a service other companies and developers can access through API's in order to develop their own applications. "So Watson is not only giving answers it is also, in some cases, posing questions to human conventional wisdom."
Relationships of this nature may often seem to be of small significance, but some of them may reveal or imply important, though implicit, relatedness between the biomedical entities, providing valuable information or knowledge in revealing deeper and more subtle connections between the related biomedical entities. All these works, though have made important progress in biomedical knowledge discovery, do not provide a unified and systematic approach to the problem of implicit knowledge discovery within the knowledge networks of multiple and different biomedical knowledge sources, thus limiting their ability to combine both structural and non-structural knowledge and information sources in discovering hidden or implicit relatedness between biomedical entities. To overcome or at least alleviate the above mentioned shortcoming, we define a novel unified computational framework based on a network of biomedical entities across multiple and different knowledge and information sources such as disease ontology, gene ontology and PubMed, linked using inter-relationships between them. The main contribution of our work is the formulation and implementation of a unified computational framework based on which a hybrid biomedical knowledge network can be structural, concept relatedness and relatedness networks can be computed using a formal inference mechanism based on set-theoretic operations.

The Gear Fit 2 only works with smartphones (any phone, not just Samsung ones) running Android 4.4 and higher. You can select from a number of different watch face homescreens (activated by pressing and holding down the watch face). Press the home button from the watch homescreen and you'll bring up a vertical list of apps.
Even to create software (software engineering) more or less directly from such a model. If you read up a little on the number of dimensions in string theory, you will find that 11 dimension string theory can describe all versions, and that 9 matrices is also compatible with one or more of them. So we can observe that what is hard for AI: establish the relation between very broad categories ... is hard for humans as well. The scientists knew their science, the kidnapped person knew her kidnapper (the observer did not).
