heuristic
Adjective:
- Relating to a method of learning or problem-solving that allows people to discover things for themselves: A "heuristic" approach involves using practical, experience-based techniques to find solutions, often through trial and error, rather than following strict formulas.
- Enabling a person to learn or discover something on their own: It describes a process that guides investigation and discovery.
Noun:
- A simple, efficient rule or mental shortcut derived from experience: A "heuristic" is a practical, commonsense principle that helps in decision-making and problem-solving, though it may not guarantee a perfect solution.
- A strategy that often speeds up the process of finding a satisfactory answer: It is a rule of thumb used to reduce cognitive effort.
Adjective:
- The teacher used a heuristic method, encouraging students to explore the concepts through experiments.
- This software employs heuristic algorithms to detect potential security threats.
Noun:
- A common heuristic for judging distance is that objects that appear hazy are farther away.
- "If it's not broken, don't fix it" is a popular heuristic in business management.
"Heuristic evaluation": In design and usability engineering, this is a method where experts examine an interface and judge its compliance with recognized usability principles (the "heuristics").
- The team conducted a heuristic evaluation to identify potential user experience issues in the app's prototype.
"Heuristic function": In computer science, particularly in search algorithms (like A*), this is a function that estimates the cost to reach the goal from a given node.
- The efficiency of the pathfinding algorithm depends heavily on the quality of its heuristic function.
Heuristically (adverb): In a way that involves or serves as a heuristic.
- The problem was solved heuristically rather than through a formal proof.
Heuristics (noun, plural form): The study or use of heuristic techniques.
- The course on cognitive psychology covered the topic of heuristics and biases in decision-making.
- Adjective: Experimental, exploratory, investigative, trial-and-error.
- Noun: Rule of thumb, mental shortcut, guideline, practical principle.
"Availability heuristic": A mental shortcut where people make judgments about the likelihood of an event based on how easily examples come to mind.
- After seeing news reports about plane crashes, people might overestimate the danger of flying due to the availability heuristic.
"Representativeness heuristic": A mental shortcut where people judge the probability of an event by finding a comparable known event and assuming the probabilities will be similar.
- Assuming someone who is quiet and likes reading is a librarian, rather than a salesperson, is an example of the representativeness heuristic.
- of or relating to or using a general formulation that serves to guide investigation
- a commonsense rule (or set of rules) intended to increase the probability of solving some problem
