In cryptography, Galois/Counter Mode (GCM) [1] is a mode of operation for symmetric-key cryptographic block ciphers which is widely adopted for its performance. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources.
In machine learning, hyperparameter optimization [1] or tuning is the problem of choosing a set of optimal hyperparameters for a learning algorithm. A hyperparameter is a parameter whose value is used to control the learning process, which must be configured before the process starts.
λI − A is surjective for some λ > 0 if and only if it is surjective for all λ > 0. (This is the aforementioned maximally dissipative case.) In that case one has (0, ∞) ⊂ ρ(A) (the resolvent set of A). A is a closed operator if and only if the range of λI - A is closed for some (equivalently: for all) λ > 0.
The W hierarchy is a collection of computational complexity classes. A parameterized problem is in the class W[i], if every instance (,) can be transformed (in fpt-time) to a combinatorial circuit that has weft at most i, such that (,) if and only if there is a satisfying assignment to the inputs that assigns 1 to exactly k inputs.
U.S. President-elect Donald Trump refused on Tuesday to rule out using military or economic action to pursue acquisition of the Panama Canal and Greenland, part of a broader expansionist agenda he ...
Executive orders signed recently by President Donald Trump state that diversity, equity and inclusion (DEI) programs prioritize diversity over merit in hiring, claiming DEI efforts are an ...
Some problems which do not have a PTAS may admit a randomized algorithm with similar properties, a polynomial-time randomized approximation scheme or PRAS.A PRAS is an algorithm which takes an instance of an optimization or counting problem and a parameter ε > 0 and, in polynomial time, produces a solution that has a high probability of being within a factor ε of optimal.
OpenAI says DeepSeek, its sudden Chinese rival, may have "inappropriately” taken data from its model to spin up its own artificial intelligence chatbot.
