Then, a convolutional neural network with compact structure and cross-domain connections is designed to learn the fabric image representation. Finally, listwise learning is introduced to train the convolutional neural network model and hash function.
WebThis study explores the listwise learning to rank with crowdsourcing labels obtained from multiple annotators, who may be unreliable. A new probabilistic ranking model is first proposed by combining two existing models. WebSupports different metrics, such as Precision, MAP, nDCG, nERR, alpha-nDCG and ERR-IA. Highly configurable functionalities for fine-tuning hyper-parameters, e.g., grid-search …
Web2.1 Learning Algorithms The learner in Listing1can be instantiated in many ways. Our framework has implementations for (1) learning from document-pairwise feedback [9, 17, 24, 26]; (2) learning from listwise feed-back, such as dueling bandit gradient descent (DBGD) [25]; and (3) extensions of DBGD, such as candidate pre-selection (CPS) [13].
