Go to Dataset Detail page. Here click on Create Model button. It will open a new page asking for Model Name. Fill the following:
1. Model Name: Name of the model. Maximum length is 180 characters.
2. Epochs: Optional. The number of training iterations for the neural network. Valid values are 1–100 (For V2 it is 1-1000). If not specified, the default is calculated based on the dataset size. The larger the number, the longer the training takes to complete.
3. Learning Rate: Optional. Specifies how much the gradient affects the optimization of the model at each time step. Use this parameter to tune your model. Valid values are between 0.0001 and 0.01. If not specified, the default is 0.0001. Salesforce recommends keeping this value between 0.0001 and 0.001.
Click on Start Training button.
It will start Training of Model and send you to the Training Status page. Your model will be available to use when training gets successfully done.
