Anki (US: / ˈɑːŋki /, UK: / ˈæŋki /; Japanese: [aŋki]) is a free and open-source flashcard program. It uses techniques from cognitive science such as active recall testing and spaced repetition to aid the user in memorization. [ 4 ][ 5 ] The name comes from the Japanese word for "memorization" (暗記).
DeepFace is a deep learning facial recognition system created by a research group at Facebook. It identifies human faces in digital images. The program employs a nine-layer neural network with over 120 million connection weights and was trained on four million images uploaded by Facebook users. [1][2] The Facebook Research team has stated that ...
Time stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which ...
Password complexity rules of enforced symbols were previously used by major platforms such as Google [53] and Facebook, [54] but these have removed the requirement following the discovery that they actually reduced security. This is because the human element is a far greater risk than cracking, and enforced complexity leads most users to highly ...
A change to Facebook’s recommendation system likely accounted for a disproportionate boost in visibility and engagement to conservative political groups on the Change in Facebook's algorithm ...
An exponential backoff algorithm is a form of closed-loop control system that reduces the rate of a controlled process in response to adverse events. For example, if a smartphone app fails to connect to its server, it might try again 1 second later, then if it fails again, 2 seconds later, then 4, etc.
Following surveys of Facebook users, [27] this desire for change will take the form of a reconfiguration of the News Feed algorithms in order to: Prioritize content of family members and friends (Mark Zuckerberg January 12, Facebook: [28] "The first changes you'll see will be in News Feed, where you can expect to see more from your friends, family and groups".)
Machine learningand data mining. Q-learning is a model-free reinforcement learning algorithm to learn the value of an action in a particular state. It does not require a model of the environment (hence "model-free"), and it can handle problems with stochastic transitions and rewards without requiring adaptations. [1]
