由 ≯℡__Kan透↙ 提交于 2021-02-08 07:19:47
问题 In Keras there is an option to set the size of the validation set batches to one: valid_batches = ImageDataGenerator().flow_from_directory(valid_path, ... batch_size=1) Is it correct that the model then just uses one object from the validation data to validate the model after each training data epoch? If that is the case then my model should not get a very good validation score. But when I run the model it runs without any problems, keeps improving and seems to be using many validation

How to replace field value in a Drupal Webform's validator?

由 痴心易碎 提交于 2021-02-08 04:46:52

I follow the validator readme to add in hook_webform_validation_validators and implement the hook_webform_validation_validate hook. However I cannot locate a return parameter to alter the submitted webform value. For example, if a user enters $12,340 , I'd like to fail the submission and update the webform value to 12340 .When the user submits the second time,

C++ input validation

由 别来无恙 提交于 2021-02-07 18:01:59
问题 I am beginning C++ programming, and have to do a lot of input validation. I have found this function that seems universally applicable, but am having trouble with one aspect; If I were to type -90, the program doesn't give an error. my question(s) are: 1. How can I add the circumstance that input cannot be <= 0? 2. Is there a better way to limit users input? Maybe a library within C++? Thank you for any help, or advice. #include <ios> // Provides ios_base::failure #include <iostream> //
