  2. Linear-nonlinear-Poisson cascade model - Wikipedia

    en.wikipedia.org/wiki/Linear-nonlinear-Poisson...

    The parameters of the LNP model consist of the linear filters {} and the nonlinearity . The estimation problem (also known as the problem of neural characterization) is the problem of determining these parameters from data consisting of a time-varying stimulus and the set of observed spike times. Techniques for estimating the LNP model ...

  3. Bilevel optimization - Wikipedia

    en.wikipedia.org/wiki/Bilevel_optimization

    Structural optimization problems consist of two levels of optimization task and are commonly referred as mathematical programming problems with equilibrium constraints . The upper level objective in such problems may involve cost minimization or weight minimization subject to bounds on displacements, stresses and contact forces.

  4. C3 linearization - Wikipedia

    en.wikipedia.org/wiki/C3_linearization

    Python's Guido van Rossum summarizes C3 superclass linearization thus: [11] Basically, the idea behind C3 is that if you write down all of the ordering rules imposed by inheritance relationships in a complex class hierarchy, the algorithm will determine a monotonic ordering of the classes that satisfies all of them.

  5. Karp's 21 NP-complete problems - Wikipedia

    en.wikipedia.org/wiki/Karp's_21_NP-complete_problems

    In computational complexity theory, Karp's 21 NP-complete problems are a set of computational problems which are NP-complete.In his 1972 paper, "Reducibility Among Combinatorial Problems", [1] Richard Karp used Stephen Cook's 1971 theorem that the boolean satisfiability problem is NP-complete [2] (also called the Cook-Levin theorem) to show that there is a polynomial time many-one reduction ...

    spaCy (/ s p eɪ ˈ s iː / spay-SEE) is an open-source software library for advanced natural language processing, written in the programming languages Python and Cython. [3] [4] The library is published under the MIT license and its main developers are Matthew Honnibal and Ines Montani, the founders of the software company Explosion.

  7. Second-order cone programming - Wikipedia

    en.wikipedia.org/wiki/Second-order_cone_programming

    SOCPs can be solved by interior point methods [2] and in general, can be solved more efficiently than semidefinite programming (SDP) problems. [3] Some engineering applications of SOCP include filter design, antenna array weight design, truss design, and grasping force optimization in robotics. [ 4 ]

  8. LP-type problem - Wikipedia

    en.wikipedia.org/wiki/LP-type_problem

    The smallest circle problem can be generalized to the smallest ball enclosing a set of balls, [3] to the smallest ball that touches or surrounds each of a set of balls, [4] to the weighted 1-center problem, [5] or to similar smaller enclosing ball problems in non-Euclidean spaces such as the space with distances defined by Bregman divergence. [6]

  9. Semidefinite programming - Wikipedia

    en.wikipedia.org/wiki/Semidefinite_programming

    A linear programming problem is one in which we wish to maximize or minimize a linear objective function of real variables over a polytope.In semidefinite programming, we instead use real-valued vectors and are allowed to take the dot product of vectors; nonnegativity constraints on real variables in LP (linear programming) are replaced by semidefiniteness constraints on matrix variables in ...
