The above is my code which I tried in Google Colab. But here it shows one error : This is error is shown in the line Please help me to solve this error. I am a beginner so answer the question with elaboration Answer Your problem is that the outputs of train_test_split are ordered differently than you think. train_test_split returns

How to find the ‘peak’ of a polynomial regression line in Matplotlib
Is it possible to find the peak (vertex?) values (x,y) of a polynomial regression line that was computed using Matplotlib? I’ve included my basic setup below (of course with fuller data sets), as well as a screenshot of the actual regression line question. would like to find x,y values along red arrows Answer You can find the maximum from the
Creating scatterplot / regression line using python
I am stuck on this problem but cannot figure out why it isn’t working as intended. I have a text file with a bunch of x and y coordinates which I need to use to find the average of all x and y values in order to calculate the slope for my regression line. It seems like stamping the individual
Can´t optimize my hyperparamters using gridsearch. Why does this not work with continous input? Alternatives?
I got a matrix Z (3000*2000), where each row describes a sample. Each column describes a single feature which is a nucleotide (A,G,T,C) and I have standardized the data so that each column contains only 0 and 1. The matrix then looks like this: And y looks like this: I tried this to do a Supportvector machine And now i
why does the mse loss had a sudden jump?
i’m working on a regression problem using neural network. the mse loss would decrease at the beginning of train and the accuracy is satisfactory, yet, when the train process goes on, the loss had a huge jump, and maintain at a certain value,like the curve in the picture. i don’t know why and how to fix it? and i wanna
Due to huge images. Can we generalize flow_from_directory method for regression problem (CNN): input image and output is x,y (float)
Data is in a CSV file which includes image path and target (x and y). where x and y belong to [-1 to 1] after scale (in keras becasue there are so many image . I can not load all in X_train like normal). Thank you so much for help! data in csv file Answer I will write here as
TypeError: fit() missing 1 required positional argument: ‘y’,
I want to try out all regressors within the library. Since I do know, that some of the regressors require more input I build the try and expept catch block. This returns the following snipped many times: In my opinion there are two problems here. First, exept never gets called. Second, the y input is not recognized. I am gratefull
get p value and r value from HuberRegressor in Sklearn
I have datasets with some outliers. From the simple linear regression, using I can get coefficient, intercept, r_value, p_value, std_err But I want to apply robust regression method as I don’t want to include outliers. So I applied Huber regressor from Sklearn, from that, I can get, coefficient, intercept, scale, outliers. I am happy with the result as the coefficient
Seaborn bar plot with regression line query
I am trying to produce a bar plot with a line of regression. I am trying to follow a previous suggestion for the same problem but get an error message that I am unable to overcome. My script is as follows: The error message I get is: but I am not sure what this means. Can anyone help? Answer Please
Plotly: How to display a regression line for one variable against multiple other time series?
With a dataset such as time series for various stocks, how can you easily display a regression line for one variable against all others and quickly define a few aesthetic elements such as: which variable to plot against the others, theme color for the figure, colorscale for the traces type of trendline; linear or non-linear?
