  • This a Bayesian ICA algorithm for the linear instantaneous mixing model with additive Gaussian noise

    This a Bayesian ICA algorithm for the linear instantaneous mixing model with additive Gaussian noise [1]. The inference problem is solved by ML-II, i.e. the sources are found by integration over the source posterior and the noise covariance and mixing matrix are found by maximization of the marginal likelihood [1]. The sufficient statistics are estimated by either variational mean field theory with the linear response correction or by adaptive TAP mean field theory [2,3]. The mean field equations are solved by a belief propagation method [4] or sequential iteration. The computational complexity is N M^3, where N is the number of time samples and M the number of sources.

    For the incomplete methods, we kept the representation of the queens by a table and the method of calculation to determine if two queens are in conflict, which is much faster for this kind of problems than the representation by a matrix. heuristics: descent. Tests: 100 queens in less than 1 second and 67 iterations. 500 queens in 1 second and 257 iterations. 1000 queens in 11 seconds and 492 iterations. heuristics: Simulated annealing. Tests: 100 queens in less than 1 second and 47 iterations. 500 queens in 5 seconds and 243 iterations. 1000 queens in 13 seconds and 497 iterations. heuristics: based on Simulated Annealing. Tests: 100 queens in less than 1 second and 60 iterations. 500 queens in 1 second and 224 iterations. 1000 queens in 5 seconds and 459 iterations. 10 000 queens in 20 minutes 30 seconds and 4885 iterations.

  • The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statisti

    The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become available. The module contains a test for singularities which is simpler and quicker than calculating the singular-value decomposition. An important feature of the algorithm is that it does not square the condition number. The matrix X X is not formed. Hence it is suitable for ill- conditioned problems, such as fitting polynomials. By taking advantage of the MODULE facility, it has been possible to remove many of the arguments to routines. Apart from the new function VARPRD, and a back-substitution routine BKSUB2 which it calls, the routines behave as in AS 274.

  • 实验描述:分布式数据库的算法partition的具体实现。即通过该算法找到关系数据库最优分裂点

    实验描述:分布式数据库的算法partition的具体实现。即通过该算法找到关系数据库最优分裂点,使得结果最优。 算法思想: 1、 首先根据所输入的attribute usage matrix得到AQ( ) 2、 对CA矩阵中划分点预先设在n-1处,并将属性列分成两个集合,TA和BA,TA中的元为:{ A1 、A2 …… An-1 },BA中的元素为:{ An} 3、 确定集合TQ、BQ和OQ,其中TQ={ qj| AQ(qi) TA},BQ= TQ={ qj| AQ(qi) BA}, OQ=Q-{TQ BQ}。 4、 计算出CTQ、CBQ、COQ这些值,其中CTQ= ,CBQ= ,COQ= 5、 通过划分点的第次移动分别计算出z=CTQ*CBQ-COQ2 6、 对取到的z的最大值处标记,为分割点 7、 对CA进行调整,重复计算得到最终z的最大值点,对CA矩阵进行划分 8、 对上述算法进行修改,将得到的最大z值的分割点和次大的分割点都记录下来,得到两个分割,则将原有的属性集划分成三部分。 该算法的目的是找到独立存取的属性集合或者分别的应用集。比如说,如果可以找到两个属性A1,A2,他们只是被q1读取,而A3,A4被q2,q3读取,这样在分裂的时候可以确定。算法就是找到这些组。另外为了简单化起见,我命令refj(qi)全部等于1.
