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 and without using a mnemonic device.
12 de abr. de 2019 · O F1-Score é simplesmente uma maneira de observar somente 1 métrica ao invés de duas (precisão e recall) em alguma situação. É uma média harmônica entre as duas, que está muito mais próxima...
Precision and recall. In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space.
Perfect recall is an epistemic-temporal notion concerning an agent's ability to remember the past. It does not entail that all knowledge an agent currently has is preserved|in fact, certain (negative) knowledge must be lost as the agent learns. For example \I know that I don't know p" is lost when I learn p.
The notion of perfect recall in extensive games was introduced by Kuhn (1953), who inter- preted it as “equivalent to the assertion that each player is allowed by the rules of the game to remember everything he knew at previous moves and all of his choices at those moves”.
In a sequential game, perfect recall refers to the assumption that, at every opportunity to act, each Player remembers what he did in prior moves, and each player remembers everything that he knew before.
1 de mai. de 2017 · This paper considers the condition of perfect recall for the class of arbitrarily large discrete extensive form games. The known definitions of perfect recall are shown to be equivalent even beyond finite games. Further, a qualitatively new characterization in terms of choices is obtained.
