QUESTION
I try to find the optimal number of topics in the LDA algorithm for my database. For this purpose I try to use the package "ldatuning". After the implementation of the LDA algorithm with the "gibbs" method I try to use the function:
Griffiths2004(models, control) The arguments should be: models An object of class "LDA control A named list of the control parameters for estimation or an object of class "LDAcontrol".
I used it like that:
...ANSWER
Answered 2021-Jun-15 at 11:13The problem probably lies in how you pass the control parameter list to the Griffiths2004 function.
In the Griffiths2004 function, the parameters are addressed as in a list using control$param. However, lda_5@control returns an S4 object where the parameters should be addressed with control@param. (An S4 object is an advanced class in R, but the only important difference for this application is, that we address objects in these lists with @ instead of $)
You can see that lda@control is an S4 object when calling it:

Answered 2021-Jun-13 at 23:01First get all the ranges between start.floor('h') and stop.ceil('h') with hour frequency using pd.date_range, then return start, range from second to second last, and stop, it'll give a list, so explode it, assign stop to this range by shifting it by -1, and finally assign start to the range, and dropna rows (this na will appear due to the effect of shift, and is not required.)

...ANSWER
Answered 2021-Jun-13 at 18:52You may want to have sorting callbacks within a mapping object (by property name or by property type).
Also, do not forget to leverage useMemo()/ useCallback() hooks to boost sorting performance through memoizing the sorting output (which may be beneficial for large number of items):
