[Question]

[nsankar]

Would like to know the dependent variable (y) used in the ML model. Is it the Cycle_Index for all the cycler data types ?

[patrickherring-TRI]

In general, no. There are several different targets for an ML model, depending on the application. In our 2019 publication, the target was the cycle_index to 80% of initial capacity, but this was because the SOC window was the same for all cells.

Hi @nsankar there are multiple ways to determine the dependent variable for the ML model. You do so by getting particular features from the structured file .

If you use the beep featurize command with all_targets you can see them; they include things like @patrickherring-TRI was saying, but they can also include properties from the diagnostic cycles.

You can also find these features programmatically with the TrajectoryFastCharge and DiagnosticProperties classes.

Thanks for the info. @ardunn @patrickherring-TRI
