Abstract: Abstract The increased use of network usage for performing online shopping and globalization has created a necessity of credit card usage throughout the world. Credit-card fraud has lead to considerable loss to the merchants and card users of about billions of dollars. Machine learning algorithm development paved the way for finding the fraud in more sophisticated ways but practical implementations are rarely reported. This paper proposed a method for deploying the fraud detection system which can efficiently find the fraud in the provided transaction. SARSA algorithm is used here for prediction of threshold value to detect the fraud accounts. Reinforcement algorithm is used for detecting the frauds. Finally, the benchmark analysis is performed to find the effectiveness of the proposed algorithm. The weight calculated from SARSA reinforcement learning algorithm is given to the random forest method to increase the accuracy the prediction of credit card defaulters.
