This means you can use the normalized data to train your model. This is done by calling the transform() function. Apply the scale to data going forward. This means you can prepare new data in the future on which you want to make predictions. The default scale for the MinMaxScaler is to...
The Pandas library in Python provides excellent, built-in support for time series data. Once loaded, Pandas also provides tools to explore and better understand your dataset. In this post, you will discover how to load and explore your time series dataset. After completing this tutorial, you ...

We’ll use theDataFrame.to_csv()method to save the modified DataFrame as a CSV file. new_df.to_csv('new_titanic.csv') This will save the CSV file in the current directory. If you need a refresher, read this tutorial onhow to get the current directory in Python. ...
Python example of kNN’s use on real-life data Let’s now go through a Python example so you can see how to use kNN in practice. Setup We will use the following data and libraries: House price data from Kaggle Scikit-learn library for1) feature scaling (MinMaxScaler...
We used a Python script to build and train the model. The steps of this process are briefly described below. 1.3. Building and training the model The script starts by importing the Python libraries which will be used in the model.
