Multiple kernel learning (MKL) approach has been proposed for kernel methods and has shown high performance for solving some real-world applications. It consists on learning the optimal kernel from one layer of multiple predefined kernels. Unfortunately, this approach is not rich enough to solve ...
We use the combined feature vectors of textual, visual , and audio modalities to train a classi-fier based on multiple kernel learning, which is known to be good at heterogeneous data. We obtain 14% performance improvement over the state of the art and present a parallelizable decision-level ...
Deep learning allows computational models that are composed of multiple processing layers to learn representations of data with multiple levels of abstraction. These methods have dramatically improved the state-of-the-art in speech recognition, visual object recognition, object detection and many other do...

in this experiment I actually did three separate runs training a network with this architecture. I then reported the test accuracy which corresponded to the best validation accuracy from any of the three runs. Using multiple runs helps reduce variation in results, which is useful when comparing ma...

Deep learning is a complex machine learning algorithm that involves learning inherent rules and representation levels of sample data through large neural networks with multiple layers. It is popular for its automatic feature extraction capabilities and is applied in various areas such as CNN, LSTM, RN...
data are complex, high-dimensional, and heterogeneous [8,9], and it is challenging to extract valuable knowledge from these multi-omics data. To address this challenge, various methods have been developed, such as multiple kernel learning, Bayesian consensus clustering, machine learning (ML)-based...
基于DL的蛋白结构预测是研究人员一直在尝试和努力的方向,大致流程是通过序列比对得到进化相关的多序列比对(multiple sequence alignment,MSA)特征,联合蛋白序列编码作为输入,利用深度网络模型预测残基间的接触图或更具体的距离分布,以及蛋白骨架...
