Beginner friendly: Challenging

Starting as an AI Fraud Detection Specialist can be challenging for beginners with no technical background or experience in machine learning. To excel in this field, one needs a solid understanding of data analysis, programming languages like Python, and machine learning algorithms. Online resources like courses on platforms such as Coursera or Udemy can help in acquiring these necessary skills. The setup costs for learning materials and courses can range from $100 to $500. It may take a minimum of 3 to 6 months to start earning a profit as one needs to build a portfolio and gain practical experience. I'd rate it a 1 because without prior knowledge or experience, most beginners may struggle to succeed in this complex field.
