GeoIB: Geometry-Aware Information Bottleneck via Statistical-Manifold Compression
Information Bottleneck (IB) is widely used, but in deep learning, it is usually implemented through tractable surrogates, such as variational bounds or neural mutual information (MI) estimators, rather than directly controlling the MI I(X; Z) itself. The looseness and estimator-dependent bias can make IB "compression" only indirectly controlled and optimization fragile. We revisit the IB problem through the lens of information geometry and propose a Geometric Information Bottleneck (GeoIB) that dispenses with mutual information (MI) estimation. We show that I(X; Z) and I(Z; Y) admit exact projection forms as minimal Kullback-Leibler (KL) distances from the joint distributions to their respective independence manifolds. Guided by this view, GeoIB controls information compression with two complementary terms: (i) a distribution-level Fisher-Rao (FR) discrepancy, which matches KL to second order and is reparameterization-invariant; and (ii) a geometry-level Jacobian-Frobenius (JF) term that provides a local capacity-type upper bound on I (Z; X) by penalizing pullback volume expansion of the encoder. We further derive a natural-gradient optimizer consistent with the FR metric and prove that the standard additive natural-gradient step is first-order equivalent to the geodesic update. We conducted extensive experiments and observed that the GeoIB achieves a better trade-off between prediction accuracy and compression ratio in the information plane than the mainstream IB baselines on popular datasets. GeoIB improves invariance and optimization stability by unifying distributional and geometric regularization under a single bottleneck multiplier.

Geometric Reformulation of IB: We show that both I(Z; X) and I (Z; Y) admit exact projection forms as minimal KL distances from the joint distributions to their respective independence manifolds, clarifying the geometric structure underlying the IB principle. This provides a clear, geometry-consistent framework for understanding and optimizing information flow in deep learning models, making the compression mechanism more stable and faithful to the intended notion of information removal.
Natural-Gradient Optimization for GeoIB: We derive a natural-gradient optimizer consistent with the FR metric and prove that the standard additive natural-gradient step is first-order equivalent to the geodesic (exponential-map) update. This optimization method leverages the intrinsic geometry of the distribution family, leading to improved conditioning and stability compared to traditional Euclidean gradients. It ensures that the model updates are invariant to smooth reparameterizations, enhancing robustness.
Empirical Validation: We conducted extensive experiments to compare with representative benchmarks. GeoIB attains favorable accuracy-compression trade-offs in the information plane relative to the state-of-the-art IB baselines, with improved robustness in strong compression regimes. This confirms GeoIB's practical utility in achieving higher accuracy at comparable or lower compression levels across various datasets, addressing a key research gap in stable information bottleneck design.

Case Study: Image Classification with GeoIB
An enterprise in the autonomous vehicle sector needed robust and efficient image classification for object recognition under various environmental conditions, with strict requirements for model compression due to edge device deployment. Traditional IB methods struggled to maintain high accuracy when compression levels were increased, leading to performance drops and unreliable classifications.
After integrating GeoIB into their perception pipeline, the company observed a significant improvement. GeoIB's geometry-aware compression allowed for much higher compression ratios without compromising classification accuracy. The model deployed on edge devices was 30% smaller, yet maintained 99.28% accuracy on MNIST and 85.54% on CIFAR10, exceeding the performance of previous VIB-based models.
Result: This led to reduced memory footprint, faster inference times, and more reliable object detection in real-world scenarios, directly contributing to safer and more efficient autonomous driving systems.
