What is the Working Principle of AutoML?

The AutoML method generally consists of the following steps:

• The user supplies the data that will be used to train the model, which gets input into the AutoML system. This is often a huge dataset that has been preprocessed and cleaned before being used to train a machine learning model.
• The AutoML system prepares the data, which usually includes activities like feature engineering and normalization. This helps to make the data suitable for training machine learning models, which may improve the reliability of the final model.
• The AutoML system uses a range of methods and hyperparameters to preprocessed data to train various machine learning models. This helps the system to determine which model performs best on the data.
• The AutoML system examines the performance of the training models and chooses the one that works best. The AutoML system uses this model as its output.
• The trained model may then be applied by the user to anticipate or act on fresh, previously unknown data. The model is often deployed as a web service that other apps or users may access.

Why to choose AutoML Solutions?
