Regression model to predict resolve time gives very poor result

Anyone aware of which regression algorithms are used to predict the resolve time of an incident ?

 Hi Adeb, currently XGboost is used as the regression algo.  Have you gone through some of the tuning recommendations for regression?

 

Also did you assess the data quality of your training set?

So we are using short desc to predict the resolve time of an incident.

We used TFIDF to vectorize the text after doing preprocessing but that does not help.

Target -Resolve time (in sec) ranges from approx 20 mins to 10 days.

 

I also tried with building the regression model in python using same data .

Performed standard preprocessing steps to cleanse, used tfidf vect and used regression algorithms like linear ,dtree,xgboost but accuracy is only around 28-30%.

Is there any series for regression to estimate resolve time similar to  https://www.youtube.com/watch?v=sKIoumkelnI
