我们采用Neyman-Rubin的潜在结果框架(Rubin,1974;Splawa-Neyman等,1990),并假设存在一个分布\mathcal{P},从中得到N个实现的独立随机变量作为训练数据:(Y_i(0), Y_i(1), X_i , W_i) ∼ \mathcal{P},其中X_i \in \mathbb{R}^d是一个d维协变量或特征向量,W_i \in \{0,1\}是否在实验组的...
In this paper we propose a machine learning model for predicting learner profile. It serves as a basis to a suitable user-centered adaptation of gamification and content. The potential of our model is considering both the player and learner contexts by integrating learners' interactions, preferences...

MLR3(Machine Learning in R 3)实际上包含的学习器(Learner)数量远超过5个,具体数量可能会随着库的更新而变化。以下是关于MLR3的一些详细信息: ### MLR3 ...
R-Learner的思路是通过做某种变换,把因果效应问题转化为一个Loss优化问题,这样的话就可以用大家早已擅长的Machine Learning的手段去优化了。 怎么做这个变换呢(这部分属于理论分析,若只想看R-Learner具体怎么做的可以跳过) 首先,基于潜在结果框架(potential outcomes framework),我们知道 ITE 定义为 \tau(x_i) := ...
This repository is about 365 days of Learning . This repository contains all the information shared during my Learn 365 Challenge.365 Days of Learning is a challenge to stay engaged in learning and personal development for a full year by setting a goal to learn something new every day, it ca...
2024年11月,期刊《Hepatology》(医学一区top,IF=12.9)发表了一篇题为:“Benchmarking clinical risk prediction algorithms with ensemble machine learning for the noninvasive diagnosis of liver fibrosis in NAFLD”的研究论文,旨在探讨Supper Learner在识别非酒精性脂肪肝病(NAFLD)患者中的显著肝纤维化(达2期及以上...
The Super Learner algorithm is relatively straightforward to implement on top of the scikit-learn Python machine learning library. In this section, we will develop an example of super learning for both regression and classification that you can adapt to your own problems. Super Learner for Regressio...
