  2. Precision and recall - Wikipedia

    en.wikipedia.org/wiki/Precision_and_recall

    In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).

  3. Recall (memory) - Wikipedia

    en.wikipedia.org/wiki/Recall_(memory)

    Free recall describes the process in which a person is given a list of items to remember and then is tested by being asked to recall them in any order. [6] Free recall often displays evidence of primacy and recency effects. Primacy effects are displayed when the person recalls items presented at the beginning of the list earlier and more often.

  4. Accuracy and precision - Wikipedia

    en.wikipedia.org/wiki/Accuracy_and_precision

    Commonly used metrics include the notions of precision and recall. In this context, precision is defined as the fraction of documents correctly retrieved compared to the documents retrieved (true positives divided by true positives plus false positives), using a set of ground truth relevant results selected by humans. Recall is defined as the ...

    en.wikipedia.org/wiki/Eidetic_memory

    Eidetic memory (/ aɪ ˈ d ɛ t ɪ k / eye-DET-ik), also known as photographic memory and total recall, is the ability to recall an image from memory with high precision—at least for a brief period of time—after seeing it only once [1] and without using a mnemonic device.

  6. Exceptional memory - Wikipedia

    en.wikipedia.org/wiki/Exceptional_memory

    Personal meaning does not seem to affect the subject's memory – they simply recall everything. [3] In another confirmed case, the subject, when shown a photograph from his past, can recall the date it was taken, where it was taken, what they had done that day, and even more detailed information such as the temperature on said day. [4]

    In cognitive psychology, a recall test is a test of memory of mind in which participants are presented with stimuli and then, after a delay, are asked to remember as many of the stimuli as possible. [ 1 ] : 123 Memory performance can be indicated by measuring the percentage of stimuli the participant was able to recall.

  9. Context-dependent memory - Wikipedia

    en.wikipedia.org/wiki/Context-dependent_memory

    In psychology, context-dependent memory is the improved recall of specific episodes or information when the context present at encoding and retrieval are the same. In a simpler manner, "when events are represented in memory, contextual information is stored along with memory targets; the context can therefore cue memories containing that contextual information".
