Encoding converts categorical data into numerical form for machine learning. Label Encoding assigns numbers, while One-Hot Encoding creates binary columns for better model performance.

❓In the code above, we have the input and output tables. Even though there are three categories in the first table, why is it enough to create two columns instead of three? Comment your answer👇!

🚀 Just published a new tutorial on one-hot encoding in Python! 📊🔥 Learn how to convert categorical data into numerical format using Pandas and Scikit-learn. Check it out on @DataCamp : https://t.co/r88FszMi2B #DataScience #MachineLearning #Python #OneHotEncoding

This is particularly useful for categorical data with a large number of categories. By using Embedding layers in neural networks, we can learn continuous vector representations that capture similarities between categories.#DataScience #MachineLearning #OneHotEncoding #Embedding

One-Hot-Encoding can lead to a significant increase in data dimensionality, which can be problematic for models with many categories.
💡 Embedding: Unlike One-Hot-Encoding, Embedding is a technique that allows data to be represented in a dense and reduced dimensionality form.
One-Hot encoding vs Label encoding
Both techniques turn categorical values into numbers.
But what is the difference then?
Let's discuss 👇
Most ML algorithms will struggle with categorical data. To avoid this, we usually use One-Hot encoding or Label encoding.
After the transformation process, we can train the models on numbers.
One-Hot encoding
This technique creates a new feature for every unique categorical value.
If we have a dataset with 3 colors, one hot encoding will create a new dataset with 3 new features.
That can lead to issues as well because for too many categories the dimensionality will increase rapidly.
For that reason, One-Hot encoding is better for data, where the number of categories is not large.
Note: By default One-Hot encoding usually uses K dummies for K categories. But that is not effective and can lead to issues. K-1 variable is enough, but more on this in another post.
Label encoding
This technique replaces each unique categorical value with a consecutive number.
For the same example dataset we will not have 3 new features, only 1.
So computationally it is more effective, but it still has drawbacks.
For example, the consecutive numbers can lead to a false impression about ranks between the values.
If Red is two and Green is 1, one could interpret it as Red > Green.
So which encoding technique to use?
It depends on the dataset or the model you want to use.
Use One-Hot encoding for not ordinal categories and less features.
Use Label encoding with ordinal data, or where the number of categories is large.

Feature encoding is key, discover 𝗢𝗻𝗲 𝗛𝗼𝘁 𝗘𝗻𝗰𝗼𝗱𝗶𝗻𝗴.
A very useful technique when you don't have many distinct values in a column.
