Robyn - Set up hyper Parameter #829

Open DongHarry-Kang opened 1 year ago

DongHarry-Kang commented 1 year ago

Hi all -

I am new to Robyn. I have a question about the setup of hyper-parameter. May I ask if I set up the hyperparameter (alpha, beta and theta for each channel) the code, are the parameters going to be fine-tuned during the simulation?

I am supposed to set up alpha, beta and theta for each channel, but what if it is a new channel which is not covered in the demo? such as youtube, face-to-face sales rep impression?

Hi, my 2 cents: you can set a number if you have this knowledge, but otherwise and more generally you'll enter a range for each hyperparamete and Robyn will try combinations for you and output the best

As Louis said, unless you know exactly what values to use for hyppars, you should use a range. The default ranges are quite large so it should be ok to use them for "new channels"

@gufengzhou Regarding the hyperparameters, if I set up the range as 0.3~0.8, which the system tune outside 0.3~0.8, what if the optimal is 0.2?
