Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing financial institution systems struggle to predict customer default events in credit products accurately and in real-time, failing to capture real-time changes in spending habits and counterparty interactions that could indicate future defaults.
Innovation Solution
Implementing an adaptively trained gradient-boosted decision-tree process using distributed computing and contextual data to analyze customer interactions and spending patterns, enabling real-time prediction of default events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional financial institution systems are used to predict customer default events, then the system complexity remains low, but the prediction accuracy and real-time capability deteriorate
Solution Approach 1:
The patent segments the prediction system into multiple specialized AI models (gradient-boosted decision trees, neural networks, support vector machines) that process different aspects of customer data independently. Each model focuses on specific patterns in transaction data, contextual data, and interaction data, allowing the overall system to achieve high prediction accuracy through coordinated specialized components rather than a single complex monolithic system.
Solution Approach 2:
The patent introduces an intermediary layer that collects and processes contextual data from multiple external sources (merchants, devices, locations, time contexts) before feeding it to the prediction models. This intermediary layer transforms raw data into meaningful features that enhance prediction accuracy without requiring the core prediction engine to directly handle complex data collection and preprocessing.
2Speed
If traditional financial institution systems are used to predict customer default events, then the computational resources required remain low, but the real-time prediction capability deteriorates
Solution Approach 1:
The patent implements preliminary action by continuously collecting and preprocessing customer interaction data, transaction data, and contextual data in advance, organizing it into structured formats ready for rapid analysis. The system pre-computes features from multiple data sources and maintains them in optimized structures, enabling the AI models to perform predictions in real-time without performing heavy data processing during the actual prediction moment.
3Measurement precision
If real-time analysis of spending habits and counterparty interactions is implemented, then the prediction accuracy improves, but the data processing complexity increases
Solution Approach 1:
The patent implements a universal data processing framework that handles multiple types of data (transaction data, contextual data, interaction data) through a single integrated architecture. The same processing pipeline and AI models process all data types uniformly, extracting relevant features regardless of source. This multi-functional approach reduces processing complexity compared to having separate specialized systems for each data type, while maintaining high prediction accuracy through comprehensive data analysis.
Data Source
AI summary
The disclosed embodiments include computer-implemented apparatuses and processes that dynamically predict future occurrences of events using adaptively trained artificial-intelligence processes and contextual data. For example, an apparatus may generate an input dataset based on first interaction data and contextual data associated with a prior temporal interval, and may apply an adaptively trained, gradient-boosted, decision-tree process to the input dataset. Based on the application of the adaptively trained, gradient-boosted, decision-tree process to the input dataset, the apparatus may generate output data representative of a predicted likelihood of an occurrence of an event during a future temporal interval, which may be separated from the prior temporal interval by a corresponding buffer interval. The apparatus may also transmit a portion of the generated output data to a computing system, and the computing system may be configured to generate or modify second interaction data based on the portion of the output data.
