The pocket algorithm then returns the solution in the pocket, rather than the last solution. It can be used also for non-separable data sets, where the aim is to find a perceptron with a small number of misclassifications. However, these solutions appear purely stochastically and hence the pocket algorithm neither approaches them gradually in ...
The first "ratchet" is applied to the symmetric root key, the second ratchet to the asymmetric Diffie Hellman (DH) key. [1] In cryptography, the Double Ratchet Algorithm (previously referred to as the Axolotl Ratchet [2] [3]) is a key management algorithm that was developed by Trevor Perrin and Moxie Marlinspike in 2013.
[48] [2] Matrix is an open communications protocol that includes Olm, a library that provides optional end-to-end encryption on a room-by-room basis via a Double Ratchet Algorithm implementation. [2] The developers of Wire have said that their app uses a custom implementation of the Double Ratchet Algorithm. [49] [50] [51]
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...

From the introduction, it is an algorithm but also a neuron: the perceptron (or McCulloch–Pitts neuron) is an algorithm. But it is also an abstract version of neurons using directed graphs and temporal logic: The perceptron was invented in 1943 by Warren McCulloch and Walter Pitts.[5] (There is no learning algorithm in the paper.)
In numerical analysis, the ITP method (Interpolate Truncate and Project method) is the first root-finding algorithm that achieves the superlinear convergence of the secant method [1] while retaining the optimal [2] worst-case performance of the bisection method. [3]
The OAEP algorithm is a form of Feistel network which uses a pair of random oracles G and H to process the plaintext prior to asymmetric encryption. When combined with any secure trapdoor one-way permutation f {\displaystyle f} , this processing is proved in the random oracle model to result in a combined scheme which is semantically secure ...
