The proposed framework relies on learning a meta-level classifier, based on the output of base-level information extraction systems. Such systems are typically trained to recognize relevant information within documents, i.e., streams of lexical units, which differs significantly from the task of ...
This paper presents application of recently proposed ensemble of classifiers called Rotation Forest to Grading meta-learning scheme, where it is used as one of the base classifiers and meta-level classifier at the same time. Our proposed Grading variation is compared to four widely used classifiers...
Combining the created training sets with SVM, we construct the base-level and meta-level classifiers. Based on these classifiers, we present a meta-learning-based detection algorithm which uses the meta-classifier to integrate the outputs of the base-classifiers and generates the final results of ...
3. 在miniImageNet 和 Fewshot-CIFAR100 (FC100)上进行大规模训练,验证效果。 注意:这篇文章里 meta-learner 指的是SS,base-learner 指的是classifier,另外还包含后期固定的feature extractor。 关于元学习【机器之心】 链接:https://www.jiqizhixin.com/articles/2019-07-01-8 训练元学习器需要一个学习器和...
使用CNN训练的classifierg_\phi代替L1距离,r_{ij}=g_\phi([\mathbb{x}_i,\mathbb{x}_j]), [.,.]代表concatention Loss function使用了MSE取代交叉熵,这是因为RN更注重样本之间的relationship,更类似于回归问题,而不是Siamese Neural Network那样的分类问题 ...
To speed up the classification process, we use a search-based method to detect the level-1 category of a test document. For this purpose, we use a category鈥揾ierarchy-based vector representation. We evaluate the meta-classifier by scaling to both longer documents as well as to a larger ...

首先作者设模型由classifier和feature extractor构成,而feature extractor中的参数又分为专门平衡BN和IN的平衡参数以及其余参数: 然后我们开始训练: Base model update 首先我们先优化整个模型在源域上的性能(源域都做不好,怎么泛化呢),所以先进行了一次普通的训练,当然这次训练不会去优化特征提取器的平衡参数。那么这次...
