How do we calculate Mean Square Error (MSE) for this. after all the calculation?

Use MSE from sklearn, or for better understanding the math you can have a look at my explanation video on MSE.

Hello I've encountered a problem, and since you seem knowledgeable about this topic, I wanted to ask you. My advisor suggested that, in order to better understand the subject, I should manually solve Ridge and LASSO regression models on a small dataset without using any software. I managed to perform Ridge regression, but I got stuck with LASSO because it doesn't have a closed-form solution. I've been searching online, but I couldn't find the information I need. As you know, I need to use the formula Σ(yᵢ - Σxᵢⱼβⱼ)² + λΣ|βⱼ|, but I can't seem to fit the values properly. For example, let's say we have built a linear regression model for Y = Bo + B1X1 using the dataset. How can I obtain the beta coefficients for this model using LASSO regression (by adding a penalty term)? I couldn't calculate it using the given formula (RSS + penalty term), to be honest. I would greatly appreciate your help. I hope I've been able to explain my problem.

Hi Sir, can you do a video tutorial on how can you improve the r2 score? Thank you

Buen video pero si pudieras mejorar la pronunciación para que youtube traduzca mejor sería excelente ¿donde está la ML Cheat Map para descargarla?

Hi Sir, for the region can we use get_dummies instead of the ordinal way(0,1,2,3)? Thank you.

Region is actually considered as nominal because regions don’t really have any ranks. But using get dummies we have chances to end-up with multicollinearity. Instead i converted them to 0,1,2,3. You can try using dummies and check the correlation matrix to see if there is any multicollinearity.

@@MLwithme1617 I think we can use dummies method and remove any one column that will work right?
