Crowdsourced human-based computational approach for tagging peripheral blood smear sample images from Sickle Cell Disease patients using non-expert users

Supervised machine learning methods rely on tagged training data [1]. The more tagged training data that is available, the more accurately the model can learn to recognize patterns and generalize to unseen data. Crowdsourcing and Human-Based Computation (HBC) has become an increasingly popular approach for acquiring training labels in machine learning classification tasks, as it can be a cost-effective way to share the labeling effort among a large number of annotators. This approach can be particularly useful in cases where expert labeling is expensive or not feasible, or where a large amount of labeled data is needed to train a machine learning model [2]. There exist various tactics for human users to contribute their problem-solving skills [3]: Altruistic contribution: This strategy involves appealing to the altruistic nature of individuals willing to contribute their time and skills to solve problems for the common good [4-6]. Gamification: This strategy involves creating engaging and fun video games incorporating problem-solving tasks [7-9].
