Building a basic prediction model with the output being the sum of the two inputs but accuracy score is significantly low
I have a csv of size 12500 X 3. The first two columns (A and B) are inputs and the the final column (C) is the sum of the two columns. I wanted to build a prediction model to get the value of C for a given A and B. This is just a basic model to imporve my understanding

I have huge Sensor log data which is in form of [key=value] pair I need to parse the data column wise i found this code for my problem the above code is suitable when the data is in form of “Priority=0, X=776517049” but my data is something like this [Priority=0][X=776517049] and there is no separator in between two columns how
How to combine multiple rows into one row WITHOUT group by in Python Pandas?
I tried searching it on stack overflow, and I got a lot of similar titles but the problem isn’t quite the same (it appears very different). Also, read some of the documentation (not all from Pandas) but couldn’t find any method to do this. Suppose I have a dataframe like: How do I combine this into one row in Pandas?

How can we make a prediction using Scikit-Learn Classifiers?
I can easily train and test a classifier using the code below. Now, how can I make a prediction of the target variable (dependent variable) based on the independent variables? Something like this should work, I think, but it doesn’t… If we leave numerics as numerics, and put quotes around labels, I would like to predict the dependent variable, but

Python data science: How to select three houses in dataset with budget constraint, optimizing for highest risidual between predicted and actual price
I have gotten the assignment to analyze a dataset of 1.000+ houses, build a multiple regression model to predict prices and then select the three houses which are the cheapest compared to the predicted price. Other than selecting specifically three houses, there is also the constraint of a “budget” of 7.000.000 total for purchasing the three houses. I have gotten
