In the diffusion adaptation formulation for modeling, the link between one brain (under rehabilitation) which follows the other (healthy) brain, the combination weights are replaced by the connectivity estimates and the corresponding EEG channels of the healthy subject are used as the targets for the adaptation algorithm. The outcome can be used as a new rehabilitation platform where the state of the patient under rehabilitation depends on how well his/her brain signals can follow the target brain signals.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134158643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, thanks to neuroplasticity, neurons are able to adapt quickly to the demands placed on them. By developing new neural networks and strengthening important connections, a cognitive training program can measurably and permanently improve brain activity. In this paper, we present a concept of AIoT based neural decoding and neurofeedback to accelerate cognitive training, the preliminary results and research directions. The proposed concept is to design adequate tiny machine learning to extract the relevant features and characteristics from physiological signals. A tiny ML performs classification or recognition of relevant patterns, based on which the neurofeedback system is appropriately designed for more effective cognitive training.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133167996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that when the underlying function can be extended as a periodic function whose bandwidth is sufficiently small relative to the evaluation budget, our models converge to a perfect reconstruction, allowing our algorithm to recover the true optimizer. For periodic bandlimited function spaces, our algorithm has reduced complexity compared to traditional GP-UCB-based algorithms and demonstrates improved robustness.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133913090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with this subtype need special treatments to prevent recurrent events that might be fatal. Thus, identifying underlying stroke categories between cardioembolic and non-cardioembolic subtypes is of great importance. We propose a multimodal machine learning model that takes into account basic clinical information and non-contrast computed tomography (CT) images to predict the risk of cardioembolic stroke. The clinical information is not only used to provide additional information for the classification model but also to guide the attention module to extract better image features. Our model achieves a score of 0.840 using the area under the receiver operating characteristic curve (ROC-AUC) metric. Besides the capability to classify the stroke subtypes, the method can provide a heatmap for large infarct localization, which is crucial for stroke diagnosis.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122411987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notwithstanding, the open nature of CRNs hardly assures security against eavesdropping. To overcome the security problem in CRNs, this paper proposes cognitive radios to transmit concurrently desired signal and artificial noise with appropriate power allocation. Apparently, such a proposal causes a trade-off between security and reliability. Moreover, to enhance energy efficiency, relaying operation should use available energy scavenged from radio frequency sources in CRNs. This paper evaluates a security-reliability trade-off of RC in CRNs with energy scavenging and artificial noise (RCiCRNwESaAN), which may benefit from improvement of transmission coverage, spectrum utilization efficiency, energy efficiency, and security capability. To do this, we recommend explicit intercept and outage probability formulas and then corroborate them by computer simulations. Eventually, multiple results are provided to have insights on RCiCRNwESaAN under these realistic operation conditions.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129367851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first provide background on the existing decoder distributions, such as Complex Gaussian and Laplace, which are equivalent to a Gamma decoder under certain conditions. We then consider separately modeling speech’s magnitude and phase information to see if we can improve the quality of either component, yielding an improvement in speech resynthesis. Extensive experiments show the Gamma decoder significantly improves magnitude reconstruction and that the von Mises decoder can weakly learn phase information. The novel Gamma decoder outperforms previous approaches, achieving a near-perfect PESQ of 4.4, representing a 42% improvement upon the state-of-the-art IS-VAE and an 86% decrease in the FAD metric.

Therefore, there is a need for more advanced malware classification methods, which can identify both known and unknown malware efficiently enough, without using signatures. In this paper, we propose a new machine-learning technique for open-world malware classification, using hyperspheres for the succinct representation of different malware families. For each malware sample that needs to be classified, we calculate the probability for it to belong to each hypersphere, then assign the sample to the family having the hypersphere with the highest probability of containing the sample point.

It is shown that the proposed variable step size approach that considers the tanh nonlinearities applied to both the preprocessed error signal with the pre-whitening filter and the error signal is beneficial for faster recovery from howling.

Due to the complexity of this process, the integration of machine learning can provide healthcare professionals with the necessary support to make accurate predictions regarding smoking behavior. To predict if a person smokes or not, the Lasso feature selection method is implemented to identify and select the most relevant features. Subsequently, a set of final subset features is utilized in conjunction with various machine learning classifiers, including LightGBM, XGBoost, Random Forest, and Multilayer Perceptron to perform the prediction task. This study aims to evaluate different classifiers and identify the one with the best performance.
