2021.01.28 daily english study log

 today was very hard for me. especially, i tried to translate the book i'm not sure this is correct title. it's name maybe  "introduction statistic learning with R". i had run out of time, i hurried to do it. the reason why i started this is i already have studied statistics and probabilitics, but most of notions about that i feels i need to practice it more. i forget many concept of theses studies and i was too hesitated becuase i am not sure the things i know can not be correct. so, from yesterday unti today's 9 pm i could wirte most of them. although i could not understand perfectly, but i can repeat broadly and it was helpful for me.

 

 and then i found the video to practice my english, i choose the one video clip of friends the topic was about holloween.. that video was the most shortest one that i can afford to watching. after wachting that, i have to take the english exam i reverved yesterday. so, in that video, talked about holloween cultures in the uk and us, and what people do in the holloween and how people have a fun. but i don't have enough time to repeat it, ended it quickly.

 

 

 

 

 oh i got something to write here. today's afternoone i made a recommendation system using csr_matrix, it was about matrix factorization. using matirx factorialization, we can decompose very big spares matrix into smaller ones. and then with converted matrx about users and recommend items, i could find what is the most recommend things for me. at that time, i could write any explanation of my codes in the jupyter noteboook markdown. before i started this dialog, i could not write anything easily comparing with now. but, it became not difficult works for me now! i was very satisfied with improvement of my writing skill. i know my grammar and vocabulary is terrible but i am so happy i don;t have any type of hesitation about writing.

 

 anyway, come back to my speaking test, i was self esteemed too much, i though that i can speak and understand english well or fluently, but it was not happend to me. serveral times i missed what theater's are saying and i was got stuck in too much. i was so depressed, It seems there was no improvement of my speaking skills compare with a week ago! but supprisingly test report was not too bad than i though, teachers gave me good points better than my though, and result of the exam seems also to be better than before.

 

 this is a report of the talking exame i had a week ago. at that time my english ekill was evaluated as 5 in case of toeic speaking and IL in case of OPIC.

 

 

 

 

 

 but in this time, i had a test in another comp, my test result was not too bad.  my speaking level was evaluated to a topeic speaking 6 and IM2 in Opic. i got a better points from 5 to 6! this result shows me that i didn't tried to practice my speaking skills with my conciousness enough, but with only shadowing training my skills become better. nevertheless, i have to do it from now. because i felt the need of it in this test.
