  2. U-Net - Wikipedia

    en.wikipedia.org/wiki/U-Net

    U-Net is a convolutional neural network that was developed for image segmentation. [1] The network is based on a fully convolutional neural network [ 2 ] whose architecture was modified and extended to work with fewer training images and to yield more precise segmentation .

  3. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    The method the operating system uses to select the page frame to reuse, which is its page replacement algorithm, is important to efficiency. The operating system predicts the page frame least likely to be needed soon, often through the least recently used (LRU) algorithm or an algorithm based on the program's working set. To further increase ...

  4. Page replacement algorithm - Wikipedia

    en.wikipedia.org/wiki/Page_replacement_algorithm

    The theoretically optimal page replacement algorithm (also known as OPT, clairvoyant replacement algorithm, or Bélády's optimal page replacement policy) [3] [4] [2] is an algorithm that works as follows: when a page needs to be swapped in, the operating system swaps out the page whose next use will occur farthest in the future. For example, a ...

  5. Cache replacement policies - Wikipedia

    en.wikipedia.org/wiki/Cache_replacement_policies

    It requires "age bits" for cache lines, and tracks the least recently used cache line based on these age bits. When a cache line is used, the age of the other cache lines changes. LRU is a family of caching algorithms, that includes 2Q by Theodore Johnson and Dennis Shasha [7] and LRU/K by Pat O'Neil, Betty O'Neil and Gerhard Weikum. [8]

  6. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...

  7. Pseudo-LRU - Wikipedia

    en.wikipedia.org/wiki/Pseudo-LRU

    The algorithm works as follows: consider a binary search tree for the items in question. Each node of the tree has a one-bit flag denoting "go left to insert a pseudo-LRU element" or "go right to insert a pseudo-LRU element". To find a pseudo-LRU element, traverse the tree according to the values of the flags.

    The "passivity" agreement FDIC wants BlackRock to sign is designed to assure bank regulators that the giant money manager will remain a "passive" owner of an FDIC-supervised bank and won’t exert ...

  9. Segmentation-based object categorization - Wikipedia

    en.wikipedia.org/wiki/Segmentation-based_object...

    Given an image D containing an instance of a known object category, e.g. cows, the OBJ CUT algorithm computes a segmentation of the object, that is, it infers a set of labels m. Let m be a set of binary labels, and let Θ {\displaystyle \Theta } be a shape parameter( Θ {\displaystyle \Theta } is a shape prior on the labels from a layered ...
