My question is: what is the best way to use the errors to figure out when to stop training? I compute the root mean squared error for each particular training instance (whic...
This rails validation code is so ugly, and there must be a better way to do it. The short story is my user is inputting data from test results. Each specific test has 4 measurements. Usually the user inputs all 5 tests (20 measurements), but it's not always required. I just need to check that if a tester started inputting data for a ...

It feels a little wrong to me to be doing Validation in your context which is your data layer. For the data layer to have a dependency on validation seems a little backwards. It makes more sense to me for validation to be done in business logic and once the validation is complete then persist the changes. The data layer should be able to...

Most people don't know to change their DOCTYPE to this: What I'd like to know is, does anyone hav...
