What are features in machine learning?

In machine learning, features are input in your system with individual independent variables. While making predictions, models use these features. In machine learning, new features can be easily obtained from old features.

Why are Features Important in Machine Learning?

Features in machine learning are extremely important as they build blocks of datasets. If the features in your dataset are of quality, the new information you will get using this dataset for machine learning will be of quality as well. Different business problems in different industries should not use the same features.

Methods of Feature Selection in ML:

• Universal Selection
• Feature Importance
• Correlation Matrix with Heatmap

The most important part of machine learning is feature engineering as it makes a difference between good and bad models.

How To Do Feature Engineering in ML?

1. Gather Data
2. Clean Data
3. Feature Engineering
4. Define Model
5. Train & Test model prediction

To perform feature engineering in machine learning you need data scientists or machine learning engineers, who are the data experts and will perform feature engineering right.
