randleon/Sentiment-Analysis---A-Machine-Learning-Approach-into-Hideo-Kojima-s-Divisive-Platformer

Our team sought to perform sentiment analysis on Twitter tweets in anticipation for Hideo Kojima's video game release, Death Stranding, in 2019. We sourced the Tweets from two libraries, preprocessed them, stored them using MongoDB and then performed sentiment analysis.

randleon/Naive-Bayes-Sentiment-Analysis_Using_Beautiful_Soup

Naïve Bayes classifiers are widely recognized for their efficacy at classifying text data (e.g., sentiment analysis). Many organizations rely on sentiment analysis algorithms to help them gauge the opinions of both existing and potential customers. Sentiment analysis algorithms to the online product/service reviews help influence business decisions

randleon/Clustering_and_SVM_to_Predict_Online_Purchases

Particular interest to most online retailers is whether or not a site visitor ends up executing a purchase while engaged with the web site. We used supervised learning methods such as K-nearest neighbors and support vector machines in Python to predict whether or not online shoppers were more willing to make a purchase.

randleon/Understanding-Classification-Model-Performance-Metrics-On-Diabetes-Dataset

Evaluation of the performance of classification models can be facilitated through a combination of calculating certain types of performance metrics and generating model performance evaluation graphics. The purpose of this exercise is to calculate a suite of classification model performance metrics via Python code functions.
