资源描述针对传统的贝叶斯算法做了相应的改进，使得效率提升了一些。里面的原始代码来自于《learning in action》这本书，这里针对源代码做了新的改进，从而提升准确率。

最小二乘拟和工具，一次直线拟和和二次去线拟和，可以直观看见拟和点与拟和曲线之间的偏差。-Least-squares fitting tools, and to be a straight line and secondary lines to be and can be seen to be intuitive and with the preparation and the deviation between the curves.

共梯度算法程序代码.数学上，共梯度法实求解特定线性系统的数值解的方法，其中那些矩阵为对称和正定。共轭梯度法是一个迭代方法，所以它适用于稀疏矩阵系统，因为这些系统对于象乔莱斯基分解这样的直接方法太大了。这种系统在数值求解偏微分方程时相当常见。 共梯度法也可以用于求解无约束优化问题。 -Total gradient algorithm program code. Mathematics, the total gradient method for solving a particular linear system is the numerical solution methods, including those for the symmetric and positive definite matrix. Conjugate gradient method is an iterative method, it applies to sparse matrix systems, because these systems such as the Cholesky decomposition of the direct method is too high. Such systems in the numerical solution of partial differential equations are quite common when. Total gradient method can also be used for solving unconstrained optimization problems.
