In a previous post, we explained how we can apply theElbow Method in Python. Here, we will use themap_dblto runkmeansusing thescaled_dataforkvalues ranging from 1 to 10 and extract the totalwithin-cluster sum of squaresvalue from each model. Then we can visualize the relationship using a...

We have theConfusion Matrixto deal with and evaluate Classification algorithms. While R square is an important error metric to evaluate the predictions made by a regression algorithm. R squared (R2)is a regression error metric that justifies the performance of the model. It represents the value o...
The calculation of z-score is simple, but less information we can find on the web for its purpose and mean. In this post, I will explain what the z-score means, how it is calculated with an example, and how to create a new z-score variable in R. As usual, I will use the ...
How to compute MACs or FLOPs of mamba?MzeroMiko commented Jan 30, 2024 We calc FLOPs based on the ref code, though it is very different from the real speed in practise. def flops_selective_scan_ref(B=1, L=256, D=768, N=16, with_D=True, with_Z=False, with_Group=True, with...
How to analytically compute inference?Question:How to analytically compute inference?Probability Distribution:The distribution in which the value of a variable varies is known as the probability distribution. In general, the probability is the ratio of the favorable number of outcomes to the total numb...
μis the mean value, nis the number of values of the entire population. This is the sample dataset. To calculate the average and standard deviation: 1. Calculating the Average in Excel 1.1. Computing the Average Manually Use the formula: ...
confident that you know what that true proportion is. These confidence interval techniques can be applied to find the exact confidence interval of a mean in R, calculate confidence interval from a p value, or even compute an exact confidence interval for variance in R from a sampling ...

Step 2)Now we need to compute of the mean with the argument na.rm = TRUE. This argument is compulsory because the columns have missing data, and this tells R to ignore them. # Create mean average_missing <- apply(df_titanic[,colnames(df_titanic) %in% list_na], ...
