Map Reduce Framework-Assisted Feature Analysis and Adaptive Multiplicative Bi-RNN Using Big Data Analytics for Decision-Making
This research proposes an automated big data analytics model for improved decision-making. It uses a Map Reduce approach for feature extraction via Spatial Incremental Principal Component Analysis (SI-PCA). To address overfitting issues common with Bidirectional Recurrent Neural Networks (BiRNN), an Adaptive Multiplicative BiRNN (AM-BiRNN) is introduced for accurate predictions. Hyperparameters are tuned using an Improved Random Function-based Sculptor Optimization Algorithm (IRF-SOA). Experimental results show 93.15% accuracy and 87.09% sensitivity, outperforming state-of-the-art techniques.

Challenges in Big Data Decision-Making
Conventional models in big data analytics suffer from significant drawbacks that impede effective decision-making. These include information loss during dimensionality reduction, a critical issue that compromises data quality and accuracy. A fundamental lack of interpretability means that the reasoning behind decisions is often opaque, making it difficult to trust or refine the system.
Moreover, traditional approaches face serious data security concerns and inherent biases within the data itself, which can lead to unfair or inaccurate outcomes. High computational complexity and resource demands, especially for large datasets, make these models inefficient. Recurrent Neural Network (RNN) models, while powerful, are prone to data bias, struggle with long-term dependencies in complex datasets, and incur high computational costs during training and testing, particularly for models like Bi-LSTM. Inconsistent data further degrades analysis quality, and the difficulty in fine-tuning parameters in complex network structures often yields suboptimal results, highlighting the need for more robust and adaptive solutions.
Novel AI-Driven Framework for Decision Making
The proposed framework integrates advanced techniques to revolutionize decision-making in big data analytics:
- Feature Extraction with MapReduce & SI-PCA: The system begins with a robust feature extraction phase leveraging the MapReduce framework and Spatial Incremental Principal Component Analysis (SI-PCA). This approach efficiently handles massive, complex datasets by parallel processing and incrementally updating principal components. SI-PCA specifically captures spatial relationships and reduces noise, ensuring that only the most relevant, high-quality features are used, effectively combating information loss and redundancy.
- Adaptive Multiplicative Bi-RNN (AM-BiRNN) for Prediction: For accurate predictions, an Adaptive Multiplicative Bi-RNN (AM-BiRNN) model is employed. This advanced neural network architecture extends the capabilities of traditional BiRNNs by incorporating multiplicative layers. These layers are designed to analyze intricate, non-linear patterns within the data, capturing long-term dependencies from both forward and backward sequences. This mitigates common issues like overfitting and excessive memory usage, leading to more robust and interpretable decision-making.
- Hyperparameter Optimization with IRF-SOA: To ensure optimal performance and speed, the AM-BiRNN's key hyperparameters (epoch count, learning rate, and hidden neuron counts) are precisely tuned by the Improved Random Function-based Sculptor Optimization Algorithm (IRF-SOA). This novel optimization algorithm is engineered to strategically navigate the solution space, maximizing the Critical Success Index (CSI) while simultaneously minimizing the False Discovery Rate (FDR) and False Negative Rate (FNR). IRF-SOA’s enhanced exploration and exploitation capabilities ensure rapid convergence to the best possible model configuration, improving stability and overall decision-making efficiency.
Superior Performance & Robustness
The experimental validation rigorously compared the proposed IRF-SOA-AM-BiRNN model against a suite of state-of-the-art heuristic algorithms and traditional deep learning schemes, demonstrating its superior capabilities:
- Unmatched Accuracy and Sensitivity: The model achieved an impressive 93.15% accuracy and 87.09% sensitivity, as reported in the abstract. Further analysis with Softmax activation even yielded a peak accuracy of 93.92% and sensitivity of 88.59% (Table 4, IRF-SOA-AM-BiRNN). This significantly surpasses the performance of conventional methods like LSTM (Accuracy: 80.93%, Sensitivity: 67.90%) and CNN (Accuracy: 88.96%, Sensitivity: 80.16%).
- Reduced Error Rates: Critically, the IRF-SOA-AM-BiRNN demonstrated minimal False Discovery Rate (FDR) and False Negative Rate (FNR). With an FDR as low as 3.16% and FNR at 11.40% (Table 4, Softmax), it drastically reduces misclassifications compared to alternatives (e.g., LSTM FDR: 5.21%, FNR: 17.90%). These low error rates are crucial for reliable decision-making in sensitive applications.
- Optimized Critical Success Index (CSI): The model achieved a high Critical Success Index (CSI) of 92.78% (Table 4, Softmax), indicating its robust capability in accurately predicting positive outcomes and overall system reliability.
- Enhanced Convergence and Stability: Convergence analysis showed that IRF-SOA-AM-BiRNN attains superior convergence speed, effectively tackling local optima issues and improving training efficiency. Its consistent performance across various batch sizes (up to 64) further validates its stability, generalizability, and resistance to overfitting and data variation.
- Overall Outperformance: The proposed framework consistently outperformed other optimization mechanisms (Cray Fish Optimization, Gold Rush Optimizer, Dark Forest Algorithm, basic Sculptor Optimization Algorithm) and deep learning models (LSTM, ACGAN, CNN) across various evaluation metrics including F1-Score, MCC, NPV, and Precision, solidifying its position as a highly effective solution for complex big data decision-making.

Real-World Impact: Customer Sentiment Analysis
The proposed IRF-SOA-AM-BiRNN model was successfully applied to the Twitter US Airline Sentiment dataset (Section 6.2). This dataset, comprising tweets from 2015, includes classifications as positive, negative, and neutral.
By accurately classifying customer suggestions (with 63% negative, 21% neutral, 16% other tweets), the model provides vital insights for quick decision-making to enhance customer satisfaction, address pain points, and target specific improvements in airline services. This demonstrates its efficacy in real-time big data analytics for critical business intelligence.
