⭐️ Content Description ⭐️
In this video, I have explained about wine quality prediction analysis. I have done basic preprocessing, EDA, class balancing, feature selection, normalization, etc., We can do both classification and regression with this dataset. I have done different types of classification for this dataset.

Hi where do you go into more detail on oversampling in another video ?

Sir I request you for a project in ml on based upon the count of the column values of the quality of wine compute the bar plot with the various quality lables on x axis and their frequency values on y axis

When you drop Free Sulfur Dioxide and Density, the Accuracy and cv score is as follows: DecisionTreeClassifier 77% 73%, ExtraTreesClassifier 84%,81% XGBoost 83%, 80%

sir, I am getting an error when I am trying to import imblearn,xgboost,lightgbm and smote what is the solution for this could you please help me out in this error

You need to install those modules, try pip install modulename in anaconda prompt

can we use confusion matrix for classification models?

@HackersRealm 2 года назад

yes you can!!!

there are seperate playlists to learn theory and practical implementations, check the channel playlist

@rani-20077 3 года назад

Which algorithm is used Is it collaborative filtering algorithm used in this model

@HackersRealm 3 года назад

it's not a recommendation problem

@shivakumarb7364 2 года назад

what are the best metrics for regressions models?

@HackersRealm 2 года назад

there are various metrics like mse, mae, rmse, etc,.

@naveenpandey9016 3 года назад

Sir I am getting an error in the last part it is showing( number of labels does not match number of samples)

@HackersRealm 3 года назад

Follow the video or print the data before training and check the no. of samples

Hi, I want to ask about Definition Of Done of ML Project. If we talked about Software Programming, we can stated that when the software is running and match with user requirement then the project is done. So if we talked about ML, what is the definition of done? Is it after getting a model with accuracy between 80-90% and CV between 80-90% ? Also need to ask about tech question : 1. does all features need to be in a normalize mode? If it doesn't and we should normalize , using log or min max? 2. Still didn't get how to read the heatmap of the correlation matrix , how can we decide to remove the features? Based on the negative one ? features a and features b can have -0.5 but features a and features c can get 0.1 and features b and features c can get 0.1 , which attribute should I remove ? 3. After getting the model, how to integrate with the front end application? And also do we need to re-train the model after several times? Thank you.

How do you account for time, is wine quality not affected by it?

@HackersRealm 2 года назад

Here we are not considering the time, based on the chemical properties alone we are trying to predict the quality!!!

Is this linear regression or any other regression please tell

I have used variety of classification models for this project

@shivakumarb7364 2 года назад

my models are giving negative cv score & accuracy, what it does meant for?

@HackersRealm 2 года назад

you used classification model?
