机器学习: Label vs. One Hot Encoder 如果您是机器学习的新手,您可能会对这两者感到困惑——Label 编码器和 One-Hot 编码器。这两个编码器是Python中 SciKit Learn 库的一部分,它们用于将分类数据或文本数据转换为数字,我们的预测模型可以更好地理解这些数字。今天,本文[1]通过一个简单的例子来了解一下两者的...
The most common type of machine learning models are discriminative. If you’re a machine learning enthusiast, it’s likely that the type of models that you’ve built or used have been mainly discriminative. These models recognize the input data and then take appropriate action. For a classifica...

have a huge effect on downstream model performance. Specifically, learning to reconstruct a larger proportion and more concentrated masked signal results in better performance on sleep classifica- tion. Our findings provide insight into how reconstruction-based SSL could help representation learning for ...
