这其实就是machine learning中的model selection问题。最理想的方法,当然就是对所有候选model的泛化误差进行评估,选择使得泛化误差最下的那个model的学习算法和参数配置。而在training的阶段,我们是无法获得一个model的泛化误差的,训练误差又由于有overfitting的存在而不适合作为评选标准,那么接下来,
0在设计机器学习算法时,一个核心问题在于如何选择hypothesis set H ,这个问题被称为model selection。 4.0 Preliminary Definitions 泛化误差 经验误差 贝叶斯误差 4.1 Estimation and Approximation Errors def1. excess errordef2. estimation errordef3. approximation error model selection就是衡量approximation error和est...
To address model under specification, in this thesis, we develop several methods that leverage domain knowledge during model selection.First, to select among solutions, one must understand the learned model. We demonstrate how one can achieve a holistic understanding by including system level knowledge...
tools called "Visualizers" that extend the scikit-learn API to allow human steering of the model selection process. In a nutshell, Yellowbrick combines scikit-learn with matplotlib in the best tradition of the scikit-learn documentation, but to produce visualizations foryourmachine learning workflow!
斯坦福大学公开课机器学习:advice for applying machine learning | model selection and training/validation/test sets(模型选择以及训练集、交叉验证集和测试集的概念) 怎样选用正确的特征构造学习算法或者如何选择学习算法中的正则化参数lambda?这些问题我们称之为模型选择问题。 在对于这一问题的讨论中,我们不仅将数据...

and an inner loop is used to select the model via k-fold cross-validation on the training fold. After model selection, the test fold is then used to evaluate the model performance. After we have identified our “favorite” algorithm, we can follow-up with a “regular” k-fold cross-vali...
