Innovative Research on Big Data Fusion and Deep Learning Methods for Intelligent Decision-Making
Intelligent decision-making systems face the dual dilemma of low data fusion efficiency and insufficient model generalization capability when processing massive multi-source heterogeneous data. Traditional decision-making methods have difficulty capturing deep semantic associations among complex data, leading to limited decision accuracy. To address these issues, this paper proposes an intelligent decision-making framework called MDDF-IDS (Multi-level Data fusion and Deep learning-Intelligent Decision System) that integrates multi-level data integration mechanisms with adaptive deep learning models. The framework achieves unified representation of heterogeneous data through a hierarchical data fusion architecture, designs a multi-model collaborative fusion strategy based on attention mechanisms to enhance feature learning capability, and establishes a decision reasoning engine to complete end-to-end optimization from data perception to decision output. Experimental results show that MDDF-IDS achieves a decision accuracy of 94.3% in financial risk assessment scenarios, representing an improvement of 12.8 percentage points over traditional methods, while model convergence speed increases by more than 40%. This validates the effectiveness and superiority of the deep learning model fusion mechanism in complex decision-making tasks, providing theoretical support and technical pathways for the engineering application of intelligent decision-making systems.

Multi-level Data Fusion Architecture
The MDDF-IDS framework employs a hierarchical data fusion architecture to unify heterogeneous data representation. It starts with a Heterogeneous Data Access Layer for standardizing diverse data types. The Feature Fusion Layer then uses multi-view learning and cross-modal attention to align and fuse features, ensuring dimension unification (512-dimensional vectors) and utilizing contrastive learning for discriminative ability. Finally, the Semantic Fusion Layer leverages knowledge graphs to map features into semantic space, providing high-level knowledge for decision reasoning. This structured approach effectively captures deep semantic associations from complex, multi-source data.
Adaptive Deep Learning Model Fusion
A core innovation is the adaptive fusion mechanism based on attention. This strategy deploys CNN, RNN, and GNN models in parallel to extract spatial, temporal, and relational features. A multi-head self-attention module dynamically calculates importance weights, enhancing feature learning and achieving complementary advantages among models. Gating mechanisms further control information flow, optimizing model combinations. This adaptive approach, combined with a multi-model collaborative decision module using reinforcement learning (DQN) and consistency verification, significantly boosts performance and reliability compared to traditional fixed-weight fusion methods.
Robust Intelligent Decision-Making Systems
The system features a hybrid decision reasoning engine that combines explicit rule-based knowledge with implicit patterns learned by deep learning models through Bayesian fusion. It includes crucial decision explanation functionality, generating readable basis descriptions to enhance transparency and user trust. For deployment, the system employs model pruning and knowledge distillation to optimize for resource-constrained environments, maintaining high accuracy with reduced parameters. Its microservice architecture supports elastic scaling and high-concurrency processing, meeting real-time decision demands in complex scenarios.
