Variable naming clarification

[matheusmartin]

I am trying to understand the Python implementation with a view to port it to another language, but can't make sense of some variables.

• hlwt at line 37.
• dlp_dw at line 86.
• dlh_dw at line 87.
• slp at line 124.
• slh at line 125.

Could someone please explain what the acronyms for the above mean?

hlwt: Weight assigned to the half-life term in the loss function during training.
dlp_dw: Partial derivative of loss function w.r.t. recall probability weights for weight updates during training.
dlh_dw: Partial derivative of loss function w.r.t. half-life term weights for updates during training.
slp: Squared error between predicted and actual recall probabilities, part of loss function.
slh: Squared error between predicted and actual half-life values, part of loss function

This is what it seems like
