2021.02.04 daily english study log

unfortunately, yesterday, i was too tired to write anything and just fall in a sleep at a night. becaus i went to the hospital and the other place because of meeting reservation. altough i did hang around a long time, you know i did work out well, got exhauseted too much. nevertheless, i did tried to watch any video and seaching anything. i found one, altough i didn't want to watch learning english with blabla, there was shipsons! i was about to watch that, but fall in a sleep.

 

 so, i could wake up ealry in this morning. then i tried to do my homework behinds me. i finished one as soon as possible, there are many things i didn't. plus, i have to participated in kaggle competition and i need to minimize rmse root mean squared error of the dataset, i tried all of thing i know but i'm not professional in kaggle, and my technique and comprehension about it was poor. that't really frustrating me despite of my hardship. i know i just see it and typing. then that looks like working well, and i passed it. but i did several times it but my comprehension is not better as much as i wish.

 

 i coun't be depressed, should stand it. i spend all of times to do ti, after submit my prediction result, there are some lower bound i have to minimized my prediction rmse less than. that was big problem for me. i made a default estimators like random forest, gradient boosting, xgb, and made some stacking models. but my stacking models doesn't seems like working, and output was something wrong. so, i  abandon it. instead, i try to used average model in base line. fortunately, the average model are working well. and i tuned hyper parameters of the models, and mixed up that models, my models become imporved.

 

 neverthese, my average model's rmse did not reach to the bound but it could be very closer at that. anyway, today i was about to practice some writing using a english book that i borrowd, but i don't have any more time for that. so i wish i can write my dialog tomorrow too.
