Introduction
This paper introduces InFusionLayer, a machine learning architecture inspired by Combinatorial Fusion Analysis (CFA) at the system fusion level. It uses a moderate set of base models to optimize unsupervised and supervised learning multiclassification problems. We demonstrate InFusionLayer's ease of use for PyTorch, TensorFlow, and Scikit-learn workflows by validating its performance on various computer vision datasets. Our results highlight the practical advantages of incorporating distinctive features of Rank-Score Characteristic (RSC) function and Cognitive Diversity (CD), paving the way for more sophisticated ensemble learning applications in machine learning.
Previous Work
Combinatorial Fusion Analysis (CFA) is a system level fusion method for combining multiple scoring systems (MSS). Given an AI/ML model A, its score function SA, and its derived rank function rA, a model's RSC function is defined as fa(i) = sA(rA⁻¹(i)). We measure model dissimilarity by calculating cognitive diversity: CD(A, B) = √(1/n Σ(fa(i) − fb(i))²). Diversity strength (DS) is a measurement of how dissimilar a model is compared to all other models being used. InFusionLayer supports average combination, weighted combination by diversity strength (WCDS), and weighted combination by performance (WCP).
Methodology
InFusionLayer handles multiclassification tasks by taking prediction outputs (logits or probabilities) as input from base models. Each prediction class is treated as a vector of data items. It generates a rank matrix and computes RSC functions. Cognitive Diversity (CD) is calculated pairwise between models. Diversity strength (DS) is then used as a weighting scheme for score and rank combinations. The tool generates 26 new models by combining base models and selects the highest-accuracy model as output, comparing it against a ground truth vector in supervised learning.
Experiments & Results
We validated InFusionLayer on computer vision datasets: MCB_A, MCB_B, ModelNet40, ModelNet10, ImageNet, and MNIST. Base models included DGCNN, PointNet++, PointCNN, PointTransformer, SplineCNN for 3D data, and ConvNeXt-Large, EfficientNet-V2-s, RegNet-Y-128GF, Swin-V2-B, ViT-B-16 for ImageNet, and Random Forest, Adaboost, SVM, XGBoost, CNN for MNIST. CFA significantly boosted accuracy; for example, on MNIST, it reached 99.06%, outperforming all individual base models. The method's robustness was demonstrated across diverse datasets and model architectures.

CFA in Drug Discovery
Combinatorial Fusion Analysis has been successfully applied in drug discovery to enhance virtual screening and improve protein structure prediction, demonstrating its versatility beyond computer vision.
"CFA has been widely used in a variety of disciplines, such as drug discovery [17], protein structure prediction [24], ChIP-seq peak detection [33], virtual screening and drug discovery [1], target tracking [28], stress detection [3], portfolio management [40], visual cognition, wireless network handoff detection [20], combining classifiers with diversity and accuracy [34], and text categorization [23] just to name a few."
