You can start with this article that I wrote in Heartbeat magazine (on Medium platform):
Jupyter notebooks covering a wide range of functions and operations on the topics of NumPy, Pandans, Seaborn, Matplotlib etc.
- Detailed Numpy operations
- Detailed Pandas operations
- Numpy and Pandas quick basics
- Matplotlib and Seaborn quick basics
- Advanced Pandas operations
- How to read various data sources
- PDF reading and table processing demo
- How fast are Numpy operations compared to pure Python code? (Read my article on Medium related to this topic)
- Fast reading from Numpy using .npy file format (Read my article on Medium on this topic)
Tutorial-type notebooks covering regression, classification, clustering, dimensionality reduction, and some basic neural network algorithms
- Simple linear regression with t-statistic generation
-
Multiple ways to perform linear regression in Python and their speed comparison (check the article I wrote on freeCodeCamp)
-
Polynomial regression using scikit-learn pipeline feature (check the article I wrote on Towards Data Science)
-
Decision trees and Random Forest regression (showing how the Random Forest works as a robust/regularized meta-estimator rejecting overfitting)
-

FlaskandGunicorn. -
Serving a recurrent neural network (RNN) through a HTTP webpage, complete with a web form, where users can input parameters and click a button to generate text based on the pre-trained RNN model. Uses
Flask,Jinja,Keras/TensorFlow,WTForms.
