Introduction to AI Simplified

Welcome to AI Simplified, where we Delve into the fascinating world of artificial intelligence. In today's article, we will be focusing on fraud detection using AI. Fraud detection is a broad topic, and for this discussion, we will be specifically comparing two approaches: XG Boost and Neural Networks. Our goal is to explore how these approaches perform in fraud detection tasks.

Obtaining the Fraud Detection Dataset

To get started, we need to obtain a fraud detection dataset. One of the popular sources for datasets is Kaggle. Kaggle is a Website that caters to data scientists and provides a wide range of datasets for various purposes. You can easily find a fraud detection dataset by simply searching on Google. In this article, we will be using the IEEE CIS Fraud Detection Dataset, which was part of a competition on Kaggle with a prize money of $20,000.

Data Exploration and Extraction

Once you have downloaded the dataset, we can proceed with data exploration and extraction. For this task, we will be using Google Colab, a cloud-Based platform that allows for easy collaboration and execution of machine learning algorithms. After connecting to Colab and your Google Drive, you can access the downloaded files. We will start by importing the necessary libraries and creating a list of file names to be extracted.

Dataset Analysis

Now, let's analyze the dataset to get a better understanding of its size and distribution. We will use the Pandas library to Read and print the extracted files. The train transaction and identity files contain 590,000 rows and 394 columns, while the test transaction and identity files have 1,144,233 rows and 41 columns. We also want to explore whether the dataset is biased or unbiased. By examining the distribution of fraud and non-fraud cases, we can determine the bias present in the dataset.

Conclusion

In conclusion, we have introduced AI Simplified and discussed fraud detection with AI. We explored the approaches of XG Boost and Neural Networks for fraud detection. We obtained the IEEE CIS Fraud Detection Dataset from Kaggle and performed data exploration and extraction using Google Colab. The dataset analysis revealed the size of the files and the biased nature of the dataset. In the next article, we will focus on pre-processing the dataset to prepare it for fraud detection tasks.

Pre-processing the Dataset for Fraud Detection

The next step in our fraud detection Journey involves pre-processing the dataset. Pre-processing is crucial for cleaning and transforming the data to make it suitable for machine learning algorithms. We will discuss various techniques such as data cleaning, handling missing values, feature scaling, and encoding categorical variables. By performing these pre-processing steps, we can improve the accuracy and effectiveness of our fraud detection models.
