You can standardize your dataset using the scikit-learn object StandardScaler. We can demonstrate the usage of this class by converting two variables to a range 0-to-1 defined in the previous section. We will use the default configuration that will both center and scale the values in each col...
In this tutorial, you will discover how to develop and evaluate Lasso Regression models in Python.After completing this tutorial, you will know:Lasso Regression is an extension of linear regression that adds a regularization penalty to the loss function during training. How to evaluate a Lasso Reg...
In the above example, you create a DataFramedfwith columnsCourses,Fee, andDuration. Then you use theDataFrame.replace()method to replacePySparkwithPython with Sparkin theCoursescolumn. This example yields the below output. Replace Multiple Strings Now let’s see how to replace multiple string colu...
How to z-transform in Python with SciPy.Stats? SciPyhas the quickest function available in statsscipy.stats.zscore(data). We’ll use this on our test scores. stats.zscore(test_scores) This will standardize each column. The output shows slightly different values than in pandas. Applying thez...
Using pandas, you can easily read text files into a DataFrame, a two-dimensional data structure similar to an Excel spreadsheet. The library supports various text file formats, such as CSV (comma-separated values), TSV (tab-separated values), and fixed-width files. Once your data is in a...
Getting the prices for S&P500 is also simple, and we can join that with our previous dataframe. We can already calculate some useful things like the daily percentage change, and the difference in value. I added some extra metrics below that I’m planning to use later on our dashboard...

squeeze=True: We hint that we only have one data column and that we are interested in a Series and not a DataFrame. One more argument you may need to use for your own data is date_parser to specify the function to parse date-time values. In this example, the date format has been ...
The Keras deep learning Python library provides an example of how to implement the encoder-decoder model for machine translation (lstm_seq2seq.py) described by the libraries creator in the post: “A ten-minute introduction to sequence-to-sequence learning in Keras.” For a detailed breakdown of...
print(dataframe.head()) Running the example confirms the 506 rows of data and 13 input variables and a single numeric target variable (14 in total). We can also see that all input variables are numeric. 1 2 3 4 5 6 7 8 9 (506, 14) 0 1 2 3 4 5 ... 8 9 10 11 12 13 ...
