Intelligence model on sequence-based prediction of PPI using AISSO deep concept with hyperparameter tuning process

Protein-protein interaction (PPI) prediction is vital for interpreting biological activities. Even though many diverse sorts of data and machine learning approaches have been employed in PPI prediction, performance still has to be enhanced. As a result, we adopted an Aquilla Influenced Shark Smell (AISSO)-based hybrid prediction technique to construct a sequence-dependent PPI prediction model. This model has two stages of operation: feature extraction and prediction. Along with sequence-based and Gene Ontology features, unique features were produced in the feature extraction stage utilizing the improved semantic similarity technique, which may deliver reliable findings. These collected characteristics were then sent to the prediction step, and hybrid neural networks, such as the Improved Recurrent Neural Network and Deep Belief Networks, were used to predict the PPI using modified score level fusion. These neural networks' weight variables were adjusted utilizing a unique optimal methodology called Aquila Influenced Shark Smell (AISSO), and the outcomes showed that the developed model had attained an accuracy of around 88%, which is much better than the traditional methods; this model AISSO-based PPI prediction can provide precise and effective predictions.

Phase-based Cepstral features for Automatic Speech Emotion Recognition of Low Resource Indian languages

Automatic speech emotion recognition (SER) is a crucial task in communication-based systems, where feature extraction plays an important role. Recently, a lot of SER models have been developed and implemented successfully in English and other western languages. However, the performance of the traditional Indian languages in SER is not up to the mark. This problem of SER in low-resource Indian languages mainly the Bengali language is dealt with in this paper. In the first step, the relevant phase-based information from the speech signal is extracted in the form of phase-based cepstral features (PBCC) using cepstral, and statistical analysis. Several pre-processing techniques are combined with features extraction and gradient boosting machine-based classifier in the proposed SER model. Finally, the evaluation and comparison of simulation results on speaker-dependent, speaker-independent tests are performed using multiple language datasets, and independent test sets. It is observed that the proposed PBCC features-based model is performing well with an average of 96% emotion recognition efficiency as compared to standard methods.

Logistic Model and Gradient Boosting Machine Model for Physical Therapy of Lumbar Disc Herniation

Objective. Physical therapy is a common clinical treatment for patients with lumbar disc herniation. The study is aimed at exploring the feasibility of mathematical expression and curative effect prediction of physical therapy in patients with lumbar disc herniation using a logistic model and gradient boosting machine (GBM). Methods. A total of 142 patients with lumbar disc herniation were treated with physical therapy. The pain was evaluated by the visual analogue scale (VAS) before each treatment. The logistic model was used to conduct a global regression analysis on patients with lumbar disc herniation. The final results of the whole course of treatment were predicted by the measured values of 2-9 times of treatment. The GBM model was used to predict and analyze the curative effect of physical therapy. Results. The mathematical expression ability of the logistic regression model for patients with lumbar disc herniation undergoing physical therapy was sufficient, and the global determination coefficient was 0.721. The results would be better for more than five measurements. The AUC of GBM mode logistic regression analysis was 0.936 and 0.883, and the prediction effect is statistically significant. Conclusion. Both the logistic and GBM model can fully express the changes in patients with lumbar disc herniation during physical therapy.
