In this section, we present our double-stage deep clustering model. In Section 4.1, we describe the pretraining phase. Pretraining allows us to learn general-purpose features to initialize the neural network. As stated before, pseudo-labels are unreliable when extracted from random latent represent...
Predicting lymph node metastasis using histopathological images based on multiple instance learning with deep graph convolution. In Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition, 4837–4846 (2020). Wang, X. et al. RetCCL: clustering-guided contrastive learning for ...
Humans and animals exhibit various forms of prosocial helping behaviour towards others in need1–3. Although previous research has investigated how individuals may perceive others’ states4,5, the neural mechanisms of how they respond to others’ needs a

Think of LDA as aBayesian networkclustering algorithm for identifying underlying groups of topicsacross a set of documents. Whenever the word Bayesian is mentioned, you know the algorithm is probabilistic! LDA considers documents asbags of words, each representing some semantic me...
With the advancement of unsupervised deep learning, theAutoencoderneural network is now frequently used for high dimensionality (e.g., a dataset with thousands or more features) reduction. Autoencoder can also be combined with supervised learning (e.g., Random Forest) to formSemi-supervised learni...
During the Check phase, any defects and errors from the deployed technologies should be calibrated to ensure an effective application. In the last step of the Act phase, before the tested system is put into daily operation, data handling, management, and cyber security measures should be ...
Deeplearning4j 是另一个专注于深度学习的 java 库。这是一个很棒的 Java 深度学习开源库。它也是用 Scala 和 Java 编写的,可以与 Hadoop 和 Spark 集成,提供高处理能力。当前的版本是测试版,但是有很好的文档和快速入门的例子(点击这里)。木槌Mallet 代表语言工具包的机器学习。它是少数几个用于自然语言处理的...
Other advanced segmentation methods for point cloud exist. It is actually a research field in which I am deeply involved, and you can already find some well-designed methodologies in the articles [1–6]. For the more advanced 3D deep learning architectures, some comprehensive tutorials ar...
