Hi everyone
I want to use CNN for my problem. The existing examples in the MATLAB (Here) provided for images as 4-D arrays but my problem is as follows:
Inputs = N (78000,24)
Output = Y(78000,1)
How can I use the mentioned examples for my problem?
Thanks in advanced.

You can use NN toolbox right? Attach your data and tell us about your data, lets give a try to help you.

yes，sir，may be use rand data to simulate your application，then you can replace data，such as
clc; clear all; close all;
% Inputs = N (78000,24);
% Output = Y(78000,1);
Inputs = randn(78000,24);
Output = rand(78000,1);
% get input data matrix
XTrain=(reshape(Inputs', [24,1,1,78000]));
YTrain=Output;
layers = [imageInputLayer([24 1 1])
convolution2dLayer([15 1],3,'Stride',1)
batchNormalizationLayer
reluLayer
maxPooling2dLayer(2,'Stride',2,'Padding',[0 0 0 1])
dropoutLayer
fullyConnectedLayer(1)
regressionLayer];
miniBatchSize = 128;
options = trainingOptions('sgdm', ...
'MiniBatchSize',miniBatchSize, ...
'MaxEpochs',30, ...
'InitialLearnRate',1e-3, ...
'LearnRateSchedule','piecewise', ...
'LearnRateDropFactor',0.1, ...
'LearnRateDropPeriod',20, ...
'Shuffle','every-epoch', ...
'Plots','training-progress', ...
'Verbose',false);
net = trainNetwork(XTrain,YTrain,layers,options);

Dear @yanqi liu
Thank you for your answered.
Could you please help me to improve the accuracy of model?
I cannot find any optimum stduture to find my data not only when considered data for training and validations, but also when considered all of them for training.
Regards,

Dear @KSSV
Thank you for your response.
I want to use CNN to solve my problem.
My data is as follows.
Inputs = [ x11 x12 x13 x14
x21 x22 x23 x24
. . . .
xN1 xN2 XN3 XN4]
Outputs = [ Y11
Y21
.
.
.
.
YN1 ]
Wher N is the number of samples (i.e., 78000)
