Semi-supervised learning refers to the model that's trained on both labeled and unlabeled data. We cover the pros & cons, as well as various techniques.
One or more computer processors extract respective features for each inter-modal sample in an inter-modal dataset, for each intra-modal sample in an intra-modal dataset, and a subsequent sample, wherein the inter-modal dataset and the intra-modal dataset are contained in a multi-modal training...
2.有标签数据训练网络,利用从网络中得到的深度特征来做半监督算法; 3.让网络 work in semi-supervised fashion。即,把网络对无标签数据的预测,作为无标签数据的标签(即 Pseudo label),用来对网络进行训练,其思想就是一种简单自训练。 就像是在制作一顿美味大餐时,你手头有一些精心调制的酱料(有标签的数据)和大量...
Label propagation is a semi-supervised technique that makes use of the labeled and unlabeled data to learn about the unlabeled data. Quite often, data that will benefit from a classification algorithm is difficult to label. For example, labeling data might be very expensive, so only a subset i...

supervised learning in practical scenarios. Google, for example, has used Noisy student training, an SSL algorithm, to improve its performance in searching [1]. The most representative SSL algorithms that currently exist usually use cross-entropy l...
Weakly-supervised learning Weakly-supervised learning[47]放松了数据依赖性,这种依赖性要求在强监督下为大量训练数据集提供基本事实标签。有三种类型的弱监督数据:不完整的监督数据、不精确的监督数据和不准确的监督数据。不完整的监督数据意味着仅标记了训练数据的子集。在这种情况下,代表性的方法是SSL和domain adaption...
In this paper, a co-training style semi-supervised regression algorithm, i.e. Coreg, is proposed. This algorithm uses two regressors each labels the unlabeled data for the other regressor, where the confidence in labeling an unlabeled example is estimated through the amount of reduction in mean...
Semi-supervised learning is a type of machine learning that combines supervised and unsupervised learning by using labeled and unlabeled data to train AI models.
