IEEE 1855

IEEE 1855 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IEEE 1855 rather than just read about it. In short: IEEE STANDARD 1855-2016, IEEE Standard for Fuzzy Markup language (FML), is a technical standard developed by the IEEE Standards Association. FML allows modelling a fuzzy logic system in a human-readable and hardware independent way.

Key takeaways

IEEE 1855 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IEEE 1855 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IEEE 1855 from memory before moving on to harder problems.

Reference excerpt

IEEE STANDARD 1855-2016, IEEE Standard for Fuzzy Markup language (FML), is a technical standard developed by the IEEE Standards Association. FML allows modelling a fuzzy logic system in a human-readable and hardware independent way. FML is based on eXtensible Markup Language (XML). The designers of fuzzy systems with FML have a unified and high-level methodology for describing interoperable fuzzy systems. IEEE STANDARD 1855-2016 uses the W3C XML Schema definition language to define the syntax and semantics of the FML programs. Prior to the introduction of FML, fuzzy logic practitioners could exchange information about their fuzzy algorithms by adding to their software functions the ability to read, correctly parse, and store the results of their work in a form compatible with the Fuzzy Control Language (FCL) described and specified by Part 7 of IEC 61131. FML lets people code fuzzy systems through a collection of correlated semantic tags that model the components of a classical fuzzy controller—such as knowledge base, rule base, fuzzy variables and fuzzy rules. Therefore, the FML tags used to build a fuzzy controller represent the set of lexemes used to create fuzzy expressions. To design a well-formed XML-based language, an a XML schema describes an FML context-free grammar that defines name, type, and attributes that characterized each XML element. However, since an FML program represents only a static view of a fuzzy logic controller, the so-called eXtensible Stylesheet Language Translator (XSLT) changes this static view to a computable version. Indeed, XSLTs modules can convert the FML-based fuzzy controller in a general purpose computer language using an XSL file containing the translation description. At this level, the control is executable for the hardware. In short, FML is essentially composed by three layers:

XML to create a new markup language for fuzzy logic control An XML schema to define the legal building blocks eXtensible Stylesheet Language Transformations (XSLT) to convert a fuzzy controller description into a specific language IEEE 1855 was the first standard sponsored by the IEEE Computational Intelligence Society.

Worked examples

Example 1 — a first encounter with IEEE 1855

Start with the simplest possible case. Write down what IEEE 1855 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IEEE 1855 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IEEE 1855 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IEEE 1855

In research: IEEE 1855 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IEEE 1855 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IEEE 1855 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Domain-specific programming languages, Fuzzy logic, IEEE standards, so understanding it makes those chapters shorter.
In everyday life: Look for IEEE 1855 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
