R2 is just one measure of how well the model fits the data.
想象一下,试图在2点之间拟合一条曲线。
Imagine trying to fit a curve between 2 points.
曲线拟合是一种相关性检测,而不是因果检测。
Curve fitting is correlation detection, not causation detection.
说明模型也拟合良好。
Also indicates th at the model fit the data well.
参数,和在模型拟合期间联合估计。
The parameters, and are estimated jointly during the fit of the model.

矩阵H被存储到拟合模型中的components_属性;
The matrix H is stored into the fitted model in the components_ attribute;
线性回归模型将尝试绘制直线拟合数据:.
A linear regression modelwill try to draw a straight line to fit the data:.
我们没有列出这些方法的R²系数拟合,因为它们都非常接近1。
We did not list the R² fit for these methods as all of them are very close to 1.
作为一个后果,在拟合光变曲线的参数中的不确度也被低估。
As a consequence, the uncertainties in the fit light-curve parameters are underestimated.
逻辑回归是拟合回归曲线的方法,当y是分类变量时,y=f(x)。
Logistic regression is a method for fitting a regression curve, y= f(x), when y is a categorical variable.
因此,建议在拟合决策树之前平衡数据集。
It is therefore recommended to balance the dataset prior to fitting with the decision tree.
对于这种特殊情况,我们可以通过在20个左右的epoch后停止训练来避免过拟合。
For this particular case, we could prevent overfitting by simply stopping the training after twenty or so epochs.
采样呈病态,导致拟合结果不稳定:SDSS17500*、SDSS16692*。
Pathological sampling leading to unstable fit results: SDSS17500⋆, SDSS16692⋆.
线性度:指传感器输出量与输入量之间的实际关系曲线偏离拟合直线的程度。
(1) Linearity: Refers to the degree to which the actual relationship curve between the sensor output andthe input deviates from the fitted straight line.
PReLUs改进模型拟合,额外计算成本几乎为零,且风险较小。
PReLU improves model fitting with nearly zero extra computational cost and little overfitting risk.
Each term found by the analyzer during the fit is assigned a unique integer index corresponding to a column in the resulting matrix.
它的一个非常标准的应用是在统计学中的曲线拟合,但它也同样适用于手写识别和其他模式识别问题。
A very standard application of this is the use of curve fitting in statistics, but it works well for handwriting and other pattern recognition problems.
一些曲线拟合,如四参数和五参数曲线拟合,降低数据点和曲线之间的垂直误差。
Some curve fits, such as 4P and 5P curve fits, work to minimize the vertical errors between data points and the curve.
PyMC is a Pythonmodule that implements Bayesian statistical models and fitting algorithms, including Markov chain Monte Carlo(MCMC).
(4)根据上述拟合模型,找出下一个时间步长的期望状态,更重要的是,找出股票的期望价格。
Based on the fitted model above, find out the expected regime of the next time step and, more importantly, the expected stock price.
正规化有助于防止ML模型记住训练数据示例而不是了解如何泛化发现的模式(称作过度拟合)。
Regularization helps prevent ML models from memorizing training data examples instead oflearning how to generalize the patterns it sees(called overfitting).
在这些拟合中,我们只考虑了统计不确度,因此参数的改变不能归因于系统不确度的不同的表达。
We consider only the statistical uncertainties in these fits, so that changes in parameters cannot be attributed to different interpretations of systematic uncertainties.
