My Task: I’m trying to calculate the pair-wise distance between every two samples in two big tensors (for k-Nearest-Neighbours), That is – given tensor test with shape (b1,c,h,w) and tensor train with shape (b2,c,h,w), I need || test[i]-train[j] || for every i,j. (where both test[i] and train[j] have shape (c,h,w), as those are sampes in the batch). The Problem both

Confuse why my KNN code is throwing a ValueError
I am using sklearn for KNN regressor: I get this error message: Could someone please explain this? My data is in the hundred thousands for target and the thousands for input. And there is no blanks in the data. Answer Before answering the question, Let me refactor the code. You are using a dataframe so you can index single or
AttributeError: ‘dict’ object has no attribute ‘data’
An error occurred while executing the KNN algorithm. I don’t know where the error occurred. Can anyone help me? Please. There is a code below. I don’t know why, but the code was cut. Answer One line defines: That’s a dict comprehension statement In the next loop you have It’s that use of .data that’s giving problem. With a dict
How can I convert columns of string in dataset to int?
Some of the data in the dataset are in string format and I should map all of them to the numeric form. I want to convert string data in some columns in the dataset to int int to become usable in the knn method. I wrote this code but It has this error. How can I fix it? thank you
What is clf and legend in ‘plot_decision_regions’?
What are the parameters ‘clf’ and ‘legend’ in plot_decision_regions? Answer clf is the classifier object being returned from neighbors.KNeighborsClassifier, which is likely coming from sklearn. BigBen linked the documentation already for the plot_decision_regions function, which explains what they do.
