根据海水的速度 密度 温度 盐度等计算海洋各处的压力数值(Speed ​ ​ according to the density of seawater temperature and salinity values ​ ​ calculated pressure throughout the ocean)

使用梯度下降法、随机梯度下降法和牛顿法实现的逻辑回归算法。(Using a gradient descent method, stochastic gradient descent algorithm logistic regression method and Newton' s method to achieve.)

两种涡旋光束的线性强度、强度密度和三维立体图，改变拓扑荷可以改变强度分布。(two kinds of vortex beam)

实现了图像的灰度化并进一步用于视频监视控，有信道编码，调制，信道估计等，可以广泛的应用于数据预测及数据分析。( Achieve a grayscale image and further control for video surveillance, Channel coding, modulation, channel estimation, Can be widely used in data analysis and forecast data.)

对该模型参数辨识采用递推最小二乘法，即 RLS（ recurisive least square）， 它是一种能够对模型参数进行在线实时估计的辨识方法。(The recursive least square method is used to identify the parameters of the model, that is, rls (recurisive least square), which is an online real-time estimation method for the model parameters)
