I am trying to execute createFeatures.R script, but the process is so slow. I found that this script just used the single core of CPU instead of multi cores. So, how to modify this script to implement this function.

hello, your work have an deep impression on my mind, I am appreciate your train of thought on this question, i am new to machine learning and data procession, but i can't get the data now, would you please send me the datas if you are not busy, if possible,i an looking forward to your reply.

@ttvand Thank you for sharing your code.
This code in rawToRds.R looks strange. Was it intended?

...
test$fecha_dato <- as.Date(test$fecha_dato, format="%m/%d/%Y")
...
test$fecha_alta <- as.Date(test$fecha_alta, format="%m/%d/%Y")
...
test$ult_fec_cli_1t <- as.Date(test$ult_fec_cli_1t, format="%m/%d/%Y")

The format="%m/%d/%Y" does not match the format of the test data.

Here is a sample rows of test data:

"fecha_dato","ncodpers","ind_empleado","pais_residencia","sexo","age","fecha_alta","ind_nuevo","antiguedad","indrel","ult_fec_cli_1t","indrel_1mes","tiprel_1mes","indresi","indext","conyuemp","canal_entrada","indfall","tipodom","cod_prov","nomprov","ind_actividad_cliente","renta","segmento"
