Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional approaches to monoclonal antibody discovery, particularly in epitope binning, provide a limited view of how antibodies compete when binding to an antigen, leading to resource-intensive and time-consuming experimental processes.
Innovation Solution
Deriving hidden variables based on antibody competition data using an optimization engine to generate training data, which allows for the prediction of competition patterns among antibodies without the need for exhaustive experimental runs, by implementing ensemble learning techniques and optimizing hidden variable logit values.

Engineering Contradiction Analysis
1Loss of information
If conventional epitope binning approaches are used to understand antibody competition, then a limited view of competition is achieved, but the process becomes resource intensive and time consuming
Solution Approach 1:
The patent creates a computational model that copies and simulates antibody competition dynamics in silico, replacing the need for exhaustive physical experiments. The model uses training data from limited experiments to generate virtual competition scenarios, achieving comprehensive understanding without proportional resource investment.
Solution Approach 2:
The patent performs preliminary computational analysis and model training on a subset of antibody competition data before conducting full experimental campaigns. This preliminary action identifies key competition patterns and reduces the experimental space that needs to be explored physically, saving time and resources.
2Reliability
If exhaustive experimental runs are conducted to capture all antibody competition patterns, then complete competition data is obtained, but resource efficiency decreases
Solution Approach 1:
The computational model serves itself by using training data to automatically generate predictions about antibody competition patterns without requiring continuous human-guided experimentation. The model self-optimizes by learning from data and can predict competition outcomes for antibody pairs without conducting physical experiments for every combination.
Solution Approach 2:
The patent changes the experimental parameters by moving from exhaustive physical testing to computational prediction. The model adjusts its internal parameters (hidden variable logit values) to match observed competition data, enabling reliable predictions without proportionally increasing experimental resources.
3Measurement precision
If hidden variable affinity scores are derived for all antibody pairs, then high fidelity modeling is achieved, but the number of experimental runs increases
Solution Approach 1:
The patent applies partial action by deriving hidden variable affinity scores for a representative subset of antibodies and using the computational model to predict scores for other pairs. This partial measurement approach achieves high modeling fidelity for the entire antibody set without measuring every possible pair experimentally.
Solution Approach 2:
The computational model serves multiple functions: it derives hidden variable affinity scores, predicts competition outcomes, and identifies binding patterns across all antibody pairs simultaneously. This multi-functionality achieves comprehensive modeling fidelity without proportionally increasing experimental runs.
Data Source
AI summary
Embodiments derive hidden variables based on antibody competition data to discover binding patterns. For example, antibody competition data for a plurality of antibodies and an antigen can be received, where the antibody competition data includes data values indicative of pairwise competition between antibodies. The antibody competition data can be processed to generate training data. Using the training data and an optimization engine, a plurality of hidden variables and affinity scores for the hidden variables can be derived, where affinity scores for the hidden variables are derived for each antibody and the hidden variables represent competition factors for the antigen that cause competition among the antibodies.
