Heuristic

Heuristic
A heuristic technique (/hjʉˈrɪstɨk/; Greek: "Εὑρίσκω", "find" or "discover"), sometimes called simply a heuristic, is any approach to problem solving, learning, or discovery that employs a practical methodology not guaranteed to be optimal or perfect, but sufficient for the immediate goals. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples of this method include using a rule of thumb, an educated guess, an intuitive judgment, stereotyping, profiling, or common sense. More precisely, heuristics are strategies using readily accessible, though loosely applicable, information to control problem solving in human beings and machines.[1] Example[edit] Here are a few other commonly used heuristics, from George Pólya's 1945 book, How to Solve It:[2] Psychology[edit] Well known[edit] Lesser known[edit] Related:  Extra Pounds□

how to be creative Accept that you’ve got the creative urge and it’s never going to go away. Make friends with it. Drink some tequila if you need to. Commit to the process. Engage! There is a gap between where you are and where you want to be. You eat the elephant one mouthful at a time. Creativity happens in the relationship between you and your medium, whether it’s the violin or writing or painting or puppetry or interpretive dance or start-ups or some combination thereof (interpretive dance puppetry, which I hear is wildly underrated). Find your tribe. Avoid toxic people. Seek constructive feedback. Master your tools. Master the difficult. Celebrate your progress, step by step by step. Embrace your limitations and constraints. If you don’t have any limitations, make some up. Develop creative rituals. Control your space. Be imperfect. Reframe failure. Go for bold heroic failures. Be solitary. Be social. Feed your head. Create conversation. Go where the conversation isn’t. Shift perspectives.

10 Heuristics for User Interface Design Visibility of system status The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. (Read full article on visibility of system status.) Match between system and the real world The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. (Read full article on the match between the system and the real world.) User control and freedom Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Consistency and standards Users should not have to wonder whether different words, situations, or actions mean the same thing. Error prevention Even better than good error messages is a careful design which prevents a problem from occurring in the first place. (Read full article on preventing user errors.)

List of cognitive biases In psychology and cognitive science, cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment.[1][2] They are often studied in psychology, sociology and behavioral economics.[1] A memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise,[3] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both effects can be present at the same time.[4][5] Although this research overwhelmingly involves human subjects, some studies have found bias in non-human animals as well. [edit] Association:

Cultivate Your Ecosystem Social entrepreneurs not only must understand the broad environment in which they work, but also must shape those environments to support their goals, when feasible. Borrowing insights from the field of ecology, the authors offer an ecosystems framework to help social entrepreneurs create long-lasting and significant social change. Jeroo Billimoria started the childline India Foundation in Mumbai, India, as a toll-free telephone help line connecting street children with a wide range of support services. She quickly became aware of the need to change the behavior of police, railway, and health officials. ChildLine began offering training workshops and helped launch the National Initiative for Child Protection, with government support. Through these efforts, ChildLine has served more than 3 million children in 73 cities across India, and it has changed the way officials and institutions relate to street children. The same is true for Martin Eakes at Self-Help. Self-Help’s Ecosystem

Metaheuristic Compared to optimization algorithms and iterative methods, metaheuristics do not guarantee that a globally optimal solution can be found on some class of problems. Many metaheuristics implement some form of stochastic optimization, so that the solution found is dependent on the set of random variables generated.[1] By searching over a large set of feasible solutions, metaheuristics can often find good solutions with less computational effort than can algorithms, iterative methods, or simple heuristics. As such, they are useful approaches for optimization problems.[1] Several books and survey papers have been published on the subject.[1][3][4] Properties and classification[edit] Different classifications of metaheuristics. These are properties that characterize most metaheuristics: There are a wide variety of metaheuristics[1] and a number of properties along which to classify them. One approach is to characterize the type of search strategy. Applications[edit] Contributions[edit]

Brain–computer interface A brain–computer interface (BCI), sometimes called a mind-machine interface (MMI), direct neural interface (DNI), synthetic telepathy interface (STI) or brain–machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions. Research on BCIs began in the 1970s at the University of California Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA.[1][2] The papers published after this research also mark the first appearance of the expression brain–computer interface in scientific literature. The field of BCI research and development has since focused primarily on neuroprosthetics applications that aim at restoring damaged hearing, sight and movement.

Getting Government Beyond Innovation One-Offs In pulling together this week’s Mayors Innovation Summit, Philadelphia Mayor and U.S. Conference of Mayors President Michael Nutter is responding to exploding interest from city leaders to create a radically new kind of local government: one that’s consistently good at embracing new ideas. The desire to do things differently is why the mayors in Riverside (CA), Kansas City (MO), and Nashville are among the most recent to appoint Chief Innovation Officers. It’s why Code for America, the San Francisco-based organization that connects young technologists with city halls to spur innovation, can barely keep up with demand from cities. Of course we already see a lot of innovation coming out of America’s city halls. But when you look closely, you find that many of these gains happen in spite of the prevailing culture. While that’s good, it’s clear that relying on opportunism, bureaucratic heroism, and luck to drive the innovation agenda isn’t good enough.

January 1, 1997 Discount usability engineering is our only hope. June 27, 1995 Participants in a course on usability inspection methods were surveyed 7-8 months after the course. January 1, 1995 Heuristic evaluation is a good method of identifying both major and minor problems with an interface, but the lists of usability problems found by heuristic evaluation will tend to be dominated by minor problems, which is one reason severity ratings form a useful supplement to the method. Rating usability problems according to their severity facilitates the allocation of resources to fix the most serious problems. Usability inspection is the generic name for a set of methods that are all based on having evaluators inspect a user interface. Jakob Nielsen's 10 general principles for interaction design.

Shoe Lacing Methods Mathematics tells us that there are more than 2 Trillion ways of feeding a lace through the six pairs of eyelets on an average shoe. This section presents a fairly extensive selection of 50 shoe lacing tutorials. They include traditional and alternative lacing methods that are either widely used, have a particular feature or benefit, or that I just like the look of. 50 Different Ways To Lace Shoes Criss Cross Lacing This is probably the most common method of lacing normal shoes & boots. Over Under Lacing This method reduces friction, making the lacing easier to tighten and loosen plus reducing wear and tear. Gap Lacing This simple variation of Criss Cross Lacing skips a crossover to create a gap in the middle of the lacing, either to bypass a sensitive area on the instep or to increase ankle flexibility. Straight European Lacing This traditional method of Straight Lacing appears to be more common in Europe. Straight Bar Lacing Hiking / Biking Lacing Quick Tight Lacing Ukrainian Lacing- New!

Keep Up with Your Quants “I don’t know why we didn’t get the mortgages off our books,” a senior quantitative analyst at a large U.S. bank told me a few years ago. “I had a model strongly indicating that a lot of them wouldn’t be repaid, and I sent it to the head of our mortgage business.” When I asked the leader of the mortgage business why he’d ignored the advice, he said, “If the analyst showed me a model, it wasn’t in terms I could make sense of. I didn’t even know his group was working on repayment probabilities.” The bank ended up losing billions in bad loans. We live in an era of big data. For people fluent in analytics—such as Gary Loveman of Caesars Entertainment (with a PhD from MIT), Jeff Bezos of Amazon (an electrical engineering and computer science major from Princeton), or Sergey Brin and Larry Page of Google (computer science PhD dropouts from Stanford)—there’s no problem. So what does the shift toward data-driven decision making mean for you? You, the Consumer Learn a little about analytics.
