Feng Li (SDU) teacher. “Near miss” examples Learner can query an oracle about class of an unlabeled example in the environment Learner can construct an arbitrary example and query an oracle for its label Learner can design Basic idea: Traditional supervised learning algorithms passively accept training data. Instead, query for annotations on informative images from the unlabeled data. Theoretical results show that large

毋庸置疑，如果没有数据，那么数据科学毫无用武之地。每个数据集由一个个样本（example, sample）组成， 大多时候，它们遵循独立同分布(independently and identically distributed, i.i.d.)。样本有时也叫做数据点 （data point）或者数据实例（data instance），通常每个样本由一组称为特征（features，或协变量（covariates）） 各种机器学习问题 25 办比赛14来完成这项工作。 搜索 有时，我们不仅仅希望输出一个类别或一个实值。在信息检索领域，我们希望对一组项目进行排序。以网络 搜索为例，目标不是简单的“查询（query）‐网页（page）”分类，而是在海量搜索结果中找到用户最需要的 那部分。搜索结果的排序也十分重要，学习算法需要输出有序的元素子集。换句话说，如果要求我们输出字 母表中的前5个字母，返回“A、 ，就会对图像中内容的推断造成极大的困难。 最重要的是，到目前为止我们默认数据都来自于某种分布，并且所有样本都是独立同分布的（independently and identically distributed，i.i.d.）。然而，大多数的数据并非如此。例如，文章中的单词是按顺序写的，如 果顺序被随机地重排，就很难理解文章原始的意思。同样，视频中的图像帧、对话中的音频信号以及网站上 的浏览行

sharing. However, quantization falls behind in case the data that we are quantizing is not uniformly distributed, i.e. the data is more likely to take values in a certain range than another equally sized range In this scenario, the dequantization error would be large for ranges where the data is densely distributed. Quantization-aware training can mitigate some of the losses by making the network resilient to likelihood of . Can we do better such that we assign more bits to regions where more of our data is distributed, and fewer bits to the sparser regions? Recall that huffman encoding does this by trying to create

the experimental UCC process group for the distributed backend. Users can experiment with it by creating UCC as the default process group via: torch.distributed.init_process_group(backend="ucc", kwargs) or a side process group with any default via: torch.distributed.init_process_group(backend=any_backend, default_pg_kwargs) ucc_pg = torch.distributed.new_group(backend="ucc", ucc_pg_kwargs) Announcements 75224d4c48d7ca), all batch norm multiplier is initialized as constant 1, instead of uniformly distributed between 0 and 1, as it was previously. This has caused accuracy issue for our TACOTRON2 model.
