Workflow for training machine learning models for chemical data
Переглядів 4762 роки тому
Here we set the workflow for training ML models for solving analytical chemistry problems. We read in the data, clean and pre-process the data, split data for training and validation, train a simple multilinear regression model with backward selection, and finally evaluate the performance of this model. The dataset comes from Cao et al. (DOI 10.1007/s11306-014-0727-x)

good video
Thank you it was very helpful hoping for a similar video on normalphase
Hi mam
I think one of the best detailed explanation of GCMS on the UA-cam
Tack! från Filippinerna
very nicely expalined
tnx
Great and detailed explanation. It helped me in preparing my presentation slides
Best video about chromatography I have ever seen on UA-cam. Thanks ❤
Hi can you explain if you have gas Lpg what method i can follow
Hej Anneli, I was wondering whether it is possible to find the full course somewhete, it is super interesting for me! Thanks!
Okay but not understand because don't know English completely
I think you made me love cheistry again
very nice , loved to hear such a soft voice with crystal clear clarity , thanks a lot for sharing
Is it suitable for solid and suspended samples?
Very good video. Thanks ma'am ❤
I love this course ,how can i download the powerpoint?
thank you!!
thank you
Thank you for your videos, Professor Anneli. Keep it up. Greetings from the University of Lille, France.
Likedddd it
Excellent explain
Great presentation!
This is amazing!! Can you tell me in which source I can find the images?
Awesome videos thank you!
i liked part one better
u are uhmazing
Very informative . Thanks for sharing . It will be apreciated if you could make a fetail video on MS esp Gc-Ms results .
well articulated
What a great explanation! Clear and concise!
Great explanation, good examples and discussion, helped me to prepare my lecture, thank you very much!
better than my 100 page college note, thanks alot
this is a great video. clearly explained
Nice Work! congrats!
this was really helpful!
Thanks csn I ask you some question about how to do calibration to the Gc type shmzdzu 2010
Very useful! Thank you very much!
Thank you, this is very helpful.
Can you tell me about the sources of solid extraction in antical Chemistry Imean book or any thing
Great lecture miss, thank you
In effect of pH case at pH=5.0 there is almost equal concentration of benzoic acid and benzoic ion so why we didn't getting two peaks Plzzzzz ans
Very good question! The reason is that the equilibrium between neutral form and anion is very-very fast in comparison to separation time. So each benzoic acid molecule will be about half of the time as neutral molecule and about half of the time as an anion. When the molecule is in the neutral form it will move slower but when it is anion it will move faster through the column. Therefore, it will show a retention behavior that is an average of the behavior of purely neutral form and purely anionic form.
Cool! Thank you from Russia!
You NAILED it!! Best Video on Mobile phases. Only request is voice in the video is distorted/noisy, Pl fix it for us. Thanks for making a informative video
Thank you very much for your wonderful lecture.
Need more volume Teacher
Thank you! Very useful and well-explained.
Omg this is amazingly well-explained. Thanks!
Just awesome
Thank you, the video is very informative yet easy to understand :)
