文章中提到,使用BNN,可以从后验权重分布中多次采样产生的不同输出结果中估计epistemic不确定性。 2.4.2 深度集成Deep Ensembles Lakshminaraynan2016年的工作提出了一种简化的可替代贝叶斯方法的算法,也就是Deep Ensembles(DE),DE方法概念上简化了:使用不同的初始值重复训练相同的网络结构。初始值的随机性和训练过程的...
Given a still image from a scene, the CSAIL team's deep-learning algorithm can create a brief video that simulates the future of that scene. Credit: Massachusetts Institute of Technology Living in a dynamic physical world, it's easy to forget how effortlessly we understand our surroundings. W...
This study employs a novel data-driven strategy to prediction of water saturation in tight gas reservoir powered by three recurrent neural network type deep/shallow learning algorithms—Gated Recurrent Unit (GRU), Recurrent Neural Networks (RNN), Long Short-Term Memory (LSTM), Support Vector ...
Adam is being adapted for benchmarks in deep learning papers. For example, it was used in the paper “Show, Attend and Tell: Neural Image Caption Generation with Visual Attention” on attention in image captioning and “DRAW: A Recurrent Neural Network For Image Generation” on image generatio...

Researchers in the Stanford Machine Learning Group, led by Andrew Ng, an adjunct professor of computer science, set out to develop a deep learning algorithm to detect 13 types of arrhythmia from ECG signals and partnered with the heartbeat monitor company iRhythm to collect a massive dataset tha...
In the deep learning collaborative filtering stage, similarity calculation is the most time-consuming process, so the algorithm complexity of this process is mainly analyzed. Assuming that the magnitude of the scoring matrix is denoted as m∗n, where the number of users is m and the quantity ...
作者尝试利用RBM的堆叠构建一个新的网络即deep belief nets(DBN网络)来解决explaining away。而到了现在,当时提出的DBN网络已经很少被使用了,但当时DBN网络的提出推动了之后神经网络的发展。 作者使用的理论是基于哪些假设?后验分布之所以非独立是因为有似然项,可以通过额外创建一个隐藏层,利用互补先验的方法,来消除该...
