这只是意味着这种关系不是线性的。 2.回归(Regression) 回归分析是一种数学技术,用于分析一些数据,包括一个因变量和一个(或多个)自变量,目的是找到因变量和自变量之间的最终函数关系。 回归分析的目的是找到在因变量和自变量之间的一个估计值(一个好的估计值!)。从数学上讲,回归的目的是找到最适合数据的曲线。 ...
The application of the logistic regression and frequency ratio model has demonstrated that the lower catchment of the basin has been widely dominated by the most landslide susceptibility areas than other parts of the catchment. Almost 6.92 sq km (4.05%) and 7.44 sq km (4.36%) areas out of ...
Correlation and regression analysis reveal that, on average, participants who completed the game more quickly than others had higher levels of general intelligence and processing capacity, suggesting that VR games may provide useful supplementary tools in the prediction of job performance. Still, our ...
We investigated the use of an Artificial Neural Network (ANN) to predict the Local Bond Stress (LBS) between Ultra-High-Performance Concrete (UHPC) and steel bars, in order to evaluate the accuracy of our LBS equation, proposed by Multiple Linear Regression (MLR). The experimental and numerica...
Since the homeostatic stress level is essential to the function of the LV24, a correlation can be made between DL stress predictions and myocardial function. Our methodology can be used for applications that require real-time data such as surgical or interventional procedure planning to avoid time...
Noise measurements were integrated with land-use types, road and traffic information, meteorological data and geographic information systems to construct land-use regression models. Leave-one-out cross-validation was performed to test the validity of the predictive models. The annual means of Leq,24h...
The correlation coefficients of linear regression from both MARS and ANNs were always higher than 0.950. MARS also indicated that the day of the year is the input that is most significant to the output, followed by the minimum air temperature. The results demonstrate the potential of MARS to ...
In view of the correlation of independent variable with dependent variable, the model of robust estimation based on equivalent variance-covariance is used in regression analysis. And this method is also used in GPS height interpolation. The results by the regression analysis method proposed in this ...
(iii) we propose an auto-context approach that further captures existing strong correlations across tasks, (iv) we run thorough experiments on two types of applications (classification and regression) and on a total of 11 heterogeneously annotated datasets, underlining the impact of each part of ...
