We can update the binning of our ggplot2 histogram using the bin attribute. We set bin attributes equal to the number of bins we want to display on our graph. This will help us see more or less granular data in our histogram. ggplot(data = home_data, aes(x = price)) + geom_hist...
Antimicrobial resistance (AMR) is an urgent public health threat. Advancements in artificial intelligence (AI) and increases in computational power have resulted in the adoption of AI for biological tasks. This review explores the application of AI in ba
I’m directly using feature selection technique using builtin libraries in Python. What’s the difference in results if I’ll use Weka for feature selection? Jason Brownlee Not much really, use the python methods, e.g.: https://machinelearningmastery.com/feature-selection-with-real-and-categor...
The use of bins is often referred to as binning or k-bins, where k refers to the number of groups to which a numeric variable is mapped. The mapping provides a high-order ranking of values that can smooth out the relationships between observations. The transformation can be applied to each...
Things to do before modeling Categorical → dummies, numeric → categorical: highest 10%, or H/M/L categories, binning of target or attribute for long tail strings → date variables, extract year/month/day from data Combine columns: mean, max, min or total might be more relevant ...
