Lastly, orthogonal polynomials are applied in least squares fitting for noisy data, providing a stable and efficient way to approximate underlying functions [30, 42,43,44, 74, 75]. The Taylor expansion is the most frequently applied technique for the collocation method [5, 6, 10, 11, 13, ...
车道线检测分为传统方法(手工特征提取+曲线拟合)和深度学习方法。深度学习方法能够更鲁棒,但仍有一些问题需要解决: 许多方法将车道线检测作为一个two-step的过程:feature extraction and curve fitting。 (但大多数方法都是通过基于分割的模型来提取特征的,不具有时效性。单......
By such standardization, the relative importance of each polynomial component can be compared in fitting a time trend. In longitudinal data analysis, researchers are often more interested in the pattern of change over time in the response than in which time component is more important. Therefore, ...

Hello All. I am trying to find a curve to fit a time series data set (time in years on x axis v depth in meters on y axis). When I plot my data and use the basic fitting tools to fit a 6th order polynomial to my data the fit is beautiful [magical really!]...
had fitted a 6th order polynomial trendline, and was having trouble using it to predict values. My fit is shown below, and I had no such problems with predictions matching the trendline. I suspect the user had insufficient precision in his coefficients, which is covered inTrendline Fitting ...
