与开源的hyperopt、optunity不同,Vizier是一个service而不是一个library,也就是算法开发者不需要自己部署调参服务或者管理参数存储,只需要选择合适的调参算法,如贝叶斯优化,然后Vizier就会根据模型的一些历史指标推荐最优的超参数组合给开发者,直接使用这些超参数会比自己瞎猜或者遍历参数组合得到的效果更好。当然开发者可...

看到在Python和R上都有自己的package。 R中直接install.packages即可。也可以从github上调用: 代码语言:javascript 复制 devtools::install_github('dmlc/xgboost',subdir='R-package') 但是,注意!! XGBoost仅适用于数值型向量。是的!你需要使用中区分数据类型。如果是名义,比如“一年级”、“二年级”之类的,需要变...

If you're using anaconda, it should drop packages in[your anaconda install folder]/lib/python3.5/site-packages 所以也可能是名字冲突的问题,有一个感觉可行的方案: We probably have the same problem. I solved it by telling Python explicitly where to find xgboost library. ...
