Student debt in America amounts to $1.6 trillion and is a growing concern. My personalized peer-to-peer lending platform, Coinsequence, aims to alleviate this crisis and offer a curated platform to do-good investors where they can directly invest in the students’ karma and profile. In this paper, I propose various machine learning (ML) techniques to efficiently personalize the peer-to-peer lending and find ideal investor-student matches on the platform. The investors’ search for students by entering criteria which could range from a sophisticated keyword to free-flowing text, such as from “tennis” to “volunteers at a community shelter to help stray animals get sterilized.” To analyze the inputs, I will assess Latent Dirichlet Allocation (LDA) to assort them into categories to facilitate an efficient pairing. Furthermore, I will evaluate Gradient Boosted Decision Tree ML algorithm to match the digital personas of students to investors’ searches, leveraging the clusters produced using LDA in the conditional tests for the decision tree. The Coinsequence dataset for students’ digital personas, composed of thousands of activities logged by millions of students, would be massive and would require removal of redundant dimensions and features. To execute this refinement, I will evaluate Principal Component Analysis (PCA) and a hybrid of filter and wrapper method feature selection to remove extraneous variables and extract relevant features, which would help achieve high accuracy and efficiency of the ML algorithms.
