A Conceptual Framework For White Box Neural Networks: Towards Transparent and Robust AI Models

Core Concepts

Introducing semantic features as a conceptual framework for transparent and robust white box neural networks.

Abstract

This paper proposes a new paradigm for training models by introducing semantic features in white box neural networks. The focus is on theoretical aspects rather than quantitative metrics, aiming to build interpretable models. The proof of concept model is trained on a Minimum Viable Dataset (MVD) using the MNIST dataset subset of "3" and "5" digits. The structure includes layers based on semantic features like real-valued, convolutional, affine, and logical features. Training results show high adversarial accuracy without adversarial training, minimal hyperparameter tuning, and quick training on a single CPU. Further research ideas include self-supervised learning with semantic features and exploring more complex logical features.

Stats

A well-motivated proof of concept model consists of 4 layers with ~4.8K learnable parameters.
Model achieves human-level adversarial test accuracy without adversarial training.
Training time on a single CPU is around 9 seconds per epoch.

Deeper Inquiries

How can semantic features enhance interpretability in other domains beyond image classification?

Semantic features can enhance interpretability in various domains beyond image classification by providing a structured way to capture domain-specific variations and relationships within the data. In natural language processing, for example, semantic features could represent linguistic structures such as word embeddings or syntactic patterns. By defining these features explicitly and incorporating them into neural network architectures, it becomes easier to understand how the model processes and interprets textual information.
In healthcare applications, semantic features could encode medical concepts or patient characteristics, allowing for more transparent decision-making processes in diagnostic systems or treatment recommendations. By utilizing semantic features that reflect relevant aspects of the data domain, stakeholders can gain insights into why certain predictions are made by the AI system.
Overall, the use of semantic features enables researchers and practitioners to create models that not only perform well but also provide explanations for their decisions across a wide range of domains.

What are the potential drawbacks or limitations of relying solely on semantic features in neural networks?

While semantic features offer significant benefits in terms of interpretability and generalization capabilities, there are some potential drawbacks and limitations to consider when relying solely on them in neural networks:

Complexity: Designing effective semantic features requires domain expertise and careful consideration of what aspects of the data should be captured. In complex domains with high-dimensional data, defining meaningful semantic features may be challenging.

Generalization: Semantic features may not always generalize well to unseen data if they are too specific to the training set. This could lead to overfitting issues where the model performs poorly on new instances outside its training distribution.

Scalability: As datasets grow larger and more diverse, manually crafting semantic features for every possible scenario becomes impractical. Automatically learning these representations through unsupervised methods may mitigate this limitation but introduces additional complexity.

Interpretation Bias: Relying solely on predefined semantic features may introduce bias into the model's decision-making process if certain important factors are overlooked during feature engineering.

Limited Expressiveness: Semantic feature representations might not capture all nuances present in complex datasets, potentially limiting the model's ability to learn intricate patterns effectively.
