Bayseian optimization not working properly in matlab 2018b

Hi everyone......i am using matlab 2018b and im trying to use this function makeObjFcn for creating a an objective function from my data store but for some reason it always says that it is undefined function or variable.

Undefined function or variable 'makeObjFcn'.

Although i have statistical and machine learning toolbox and also deep learning toolbox but still it does not work i also checked it in my pc that there is no file will this name also.

Hi, I also met this problem, have you solved it?

Answer 1

[Walter Roberson]

https://www.mathworks.com/help/deeplearning/examples/deep-learning-using-bayesian-optimization.html has the code. It is probably in the example source as well.

[Aamir Shabbir hussain]

No it does not have the definition for the makeObjFcn.

[Johannes Bergstrom]

The function makeObjFcn is defined in the example: https://www.mathworks.com/help/deeplearning/examples/deep-learning-using-bayesian-optimization.html

To open the example in MATLAB, use openExample('nnet/OptimizeDeepNeuralNetworksUsingBayesianOptimizationExample')

Answer 2

[Helen Victoria]

yes it doesnt have the definition

[Walter Roberson]

which MATLAB release are you using?

[Walter Roberson]

The function definition is at line 54 of

examples/nnet/main/OptimizeDeepNeuralNetworksUsingBayesianOptimizationExample.mlx

in R2018a and R2018b

It is at line 175 of

examples/nnet/main/OptimizeDeepNeuralNetworksUsingBayesianOptimizationExample.m

in R2017b.

The example does not exist in previous releases.
