鉴于卷积对于目标特征的提取及压缩的特点,数据长度(参数)越高,1D-CNN就越发有优势。因此在时序回归、高光谱分析、股票预测、音频分析上1D-CNN的表现可圈可点。此外,利用1D-CNN做回归和分类对样本量有较高的要求,因为卷积结构本身对噪声就比较敏感,数据集较少时,特别容易发生严重的过拟合现象,建议样本量800+有比较...

Matlab实现1D-2D-GASF-CNN-BiLSTM-MATT的多通道输入数据分类预测; 数据准备:准备原始的序列数据,并将其转换为格拉姆矩阵的GASF矩阵表示。这将为每个时间步创建一个GASF图像。 2D卷积神经网络(CNN):将GASF矩阵作为输入,使用2D卷积神经网络来提取图像特征。CNN会在每个GASF图像上进行卷积和池化操作,以学习到图像中的...
I am trying to learn a 1D-CNN model. I only have sequence input examples, but I want to learn CNN with no sequence input. My data is a one-dimensional vector. When I input a one-dimensional vector as 100x1 as a cell, I failed to train the network because matlab outputs errors. H...
Open in MATLAB Online Hi there, I'm relatively new to CNNs and currently exploring the application of CNNs to 1 dimensional data sets and would greatly appreciate some assistance with an error relating to the trainNetwork function. Despite having checked and rechecked the label array repeatedly,...
