Abstract
Traditional transformer architectures utilize sequential layer connectivity, limiting the complexity of potential interactions. This paper proposes a novel modification by introducing randomized, non-sequential layer connectivity aimed at enhancing the model's creativity, learning capabilities, and problem-solving efficiency. Additionally, we explore integrating external model feedback to optimize these new connections dynamically. This proposal outlines the architectural changes, necessary training methodologies, and the potential improvements in learning outcomes.
Introduction Transformers, fundamental to tasks involving language understanding and generation, follow an encoder-decoder structure with layers communicating directly only with adjacent ones. Inspired by human cognitive processes that involve non-linear and non-sequential thinking, our proposed architecture and its modifications aim to more closely mimic these complex interactions. The integration of feedback from external models serves to further enhance and refine the connectivity dynamics within the network.
Background Introduced by Vaswani et al. (2017), transformers have predominantly relied on straightforward, sequential information flow. However, studies into human cognition suggest that non-linear connections can lead to greater creativity and efficiency in problem-solving (Dehaene, 2014). This understanding forms the basis for our proposed modifications to the traditional transformer model.
Proposed Architecture Modifications to Transformer Architecture Our model introduces mechanisms allowing each layer to form connections with any other layer in the network. These connections are managed via:
Extended Attention Mechanisms: These are designed to compute attention scores from multiple preceding layers, not just the immediately preceding one. Stochastic Layer Pairing Strategy: During training, layers dynamically pair based on optimization criteria like loss reduction or information gain.
Structural Details Randomized Connection Module: Includes a module in each layer to manage non-sequential connections, using a reinforcement learning approach to optimize these based on performance feedback. Adaptive Control Gates: These gates regulate information flow from multiple layers, akin to mechanisms seen in LSTMs. Training Methodologies.
Modified Training Algorithms Given the complexity introduced by these connections, traditional backpropagation is adapted to include:
Layer-Wise Adaptive Learning Rates: These are essential due to the disparate impacts of various connections. Reinforcement Learning for Connectivity: Utilizes feedback on the network's state and actions to adjust connections for optimal long-term rewards.
Integrating External Model Feedback Feedback networks evaluate the main network's outputs and intermediate states, guiding connectivity adjustments:
Dual-Network Configuration: Comprises primary (main) and secondary (feedback) networks—the latter assesses output from the former. Dynamic Adjustment of Connections: Connections between layers are adjusted dynamically based on feedback, enhancing adaptability.
Hypothesized Benefits
Enhanced Creativity and Problem Solving By mimicking non-linear human thought processes, the network can potentially offer more innovative solutions and better problem-solving capabilities.
Learning Efficiency Connections that adapt based on task-specific feedback lead to more efficient learning, focusing computational resources where most needed.
Conclusion This paper presents foundational concepts for modifying transformer architectures to include non-sequential layer connectivity, supplemented by dynamic feedback mechanisms. These innovations aim to create models that not only learn more efficiently but also achieve higher creativity and adaptability in problem-solving tasks.
