Hello everyone ,i hope you are doing well. I have trained a Feedforward neural network using pattern recognition app. I have five classes the model gives the output in vec2ind form .

I want to output to be in string form for example.

if the model predict class=4 i want to print 'Rectangle Class'

if model class=3 i want to print 'Circle Class' similary for all 5 classes

I have attched the model and the test file which predict class=4

Can anybody help me in that please

load('FNNmodel.mat')
net=trainedmodel.Network
y=net(dataset21');
classes=vec2ind(y)

if model class=3 i want to print 'Circle Class' similary for all 5 classes

load('FNNmodel.mat')
net=trainedmodel.Network
y=net(dataset21');
base_db = {'class1','class2','Circle Class','Rectangle Class','class5'};
classes=base_db{vec2ind(y)}

classes =

'Rectangle Class'

在 MATLAB Online 中打开

load('FNNmodel.mat')
load('dataset31')
net=trainedmodel.Network
y=net(dataset21');
base_db = {'class1','class2','Circle Class','Rectangle Class','class5'};
classes=base_db(vec2ind(y))

classes =

1×3 cell 数组

列 1 至 2

{'Rectangle Class'} {'class5'}

列 3

{'Circle Class'}
