+# Learning Goals  
+- Gain proficiency in **Exploratory Data Analysis (EDA)**.  
+- Understand and apply **data fraud analysis techniques**.  
+- Learn to identify anomalies in datasets effectively.  
+
+# Exercise Statement  
+**Objective**: Conduct a comprehensive data fraud analysis on a **battery swap service dataset**.  
+The dataset contains details of battery swaps across various stations in a city. Your tasks include:  
+- Identifying potential fraudulent activities, such as revenue losses due to inconsistencies in swap data.  
+- Proposing effective solutions for detecting and preventing such fraud.  
+
+This exercise will not only enhance your analytical skills but also provide practical experience in applying machine learning models for anomaly detection.  
+
+# Prerequisites  
+Before starting this exercise, ensure you have a foundational understanding of:  
+- Data manipulation techniques using **Python** and **Pandas**.  
+- Concepts and implementations of **K-Means clustering** and **Isolation Forests** for anomaly detection.  
+
+# Dataset Summary  
+The dataset for this exercise provides real-world data on battery swap activities across city stations. It contains variables such as:  
+- Swap station ID  
+- Timestamp of battery swaps  
+- Battery charge levels before and after swaps  
+- Revenue details  
+
+This data allows you to apply fraud detection techniques and design automated alerts to minimize revenue losses.  
+
+# (Optional) Suggested/Proposed Solutions  
+A potential solution involves the use of **K-Means clustering** to group similar data points and **Isolation Forests** to detect outliers representing anomalies. If required, I can create a pull request with a detailed solution.  
+
+# (Optional) Further Links & Credits  
+This exercise and solution proposal stemmed from insights shared during a **DL2020 lab session**. Additional resources on fraud analysis techniques can be found [here](#).
