Credit default project, in which I tested different simulation models for credit data to see which one is best suited to create a prediction of who will and won't repay the debt. The goal of the project is to find the best model for the dataset using model quality assessment methods.
In this project, I show that we can retrieve relevant Marvel Comics using various python libraries alongside NLP methods like the bag-of-words (BoW) model for feature extraction from text & dictionary building, the Tf-Idf model to identify the most important words and the MatrixSimilarity model to find similar comics.
The purpose of this web scraper is to extract information about products on Amazon, such as the product title, price, rating, number of reviews, and product description. This data can then be used for analysis or to inform business decisions.
The purpose of the project is to show how to use SQL to extract insights from COVID-19 data. The project covers various topics such as importing data from different sources, cleaning and preprocessing data, and performing SQL queries to analyze the data.
Exploratory Data Analysis (EDA) is a crucial step in the data analysis process where the goal is to analyze and summarize the main characteristics of a dataset. EDA helps analysts to get a better understanding of the data, detect patterns, identify relationships, and detect outliers or anomalies.
In this project, I automated an API pull, as well as cleaned up the data. Finished with visualizations to better showcase the results.
