  2. Sparse identification of non-linear dynamics - Wikipedia

    en.wikipedia.org/wiki/Sparse_identification_of...

    Sparse identification of nonlinear dynamics (SINDy) is a data-driven algorithm for obtaining dynamical systems from data. [1] Given a series of snapshots of a dynamical system and its corresponding time derivatives, SINDy performs a sparsity-promoting regression (such as LASSO) on a library of nonlinear candidate functions of the snapshots against the derivatives to find the governing equations.

  3. Memory model (programming) - Wikipedia

    en.wikipedia.org/wiki/Memory_model_(programming)

    The memory model specifies synchronization barriers that are established via special, well-defined synchronization operations such as acquiring a lock by entering a synchronized block or method. The memory model stipulates that changes to the values of shared variables only need to be made visible to other threads when such a synchronization ...

  4. Multiple instruction, multiple data - Wikipedia

    en.wikipedia.org/wiki/Multiple_instruction...

    In shared memory model the processors are all connected to a "globally available" memory, via either software or hardware means. The operating system usually maintains its memory coherence. [4] From a programmer's point of view, this memory model is better understood than the distributed memory model.

  5. Tracing garbage collection - Wikipedia

    en.wikipedia.org/wiki/Tracing_garbage_collection

    In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them.

  6. Memory-bound function - Wikipedia

    en.wikipedia.org/wiki/Memory-bound_function

    The new egalitarian approach is to rely on memory-bound functions. As stated before, a memory-bound function is a function whose computation time is dominated by the time spent accessing memory. A memory-bound function accesses locations in a large region of memory in an unpredictable way, in such a way that using caches are not effective.

  7. Bidirectional associative memory - Wikipedia

    The memory or storage capacity of BAM may be given as (,), where "" is the number of units in the X layer and "" is the number of units in the Y layer. [3]The internal matrix has n x p independent degrees of freedom, where n is the dimension of the first vector (6 in this example) and p is the dimension of the second vector (4).

  8. Single instruction, multiple data - Wikipedia

    en.wikipedia.org/wiki/Single_instruction...

    Function multi-versioning (FMV): a subroutine in the program or a library is duplicated and compiled for many instruction set extensions, and the program decides which one to use at run-time. Library multi-versioning (LMV): the entire programming library is duplicated for many instruction set extensions, and the operating system or the program ...

  9. Kernel (statistics) - Wikipedia

    en.wikipedia.org/wiki/Kernel_(statistics)

    In statistics, especially in Bayesian statistics, the kernel of a probability density function (pdf) or probability mass function (pmf) is the form of the pdf or pmf in which any factors that are not functions of any of the variables in the domain are omitted. [1] Note that such factors may well be functions of the parameters of the
