Coded computing has proven its efficiency in tolerating stragglers in distributedcomputing. Workers return the sub-computation results to the master after computing, and the master recovers the final computation result by decoding. However, the workers may provide incorrect results, which leads to wrong final result. Therefore, it is meaningful to improve the resilience of coded computing against errors. Most existing verification schemes only use the workers' fully correct computations to recover the final result, and the defective computations are not considered for decoding. In this paper, we focus on matrix multiplication and design a general Test-and-Decode (TD) scheme to recover the final result efficiently. Furthermore, we divide each sub-computation result into multiple parts and fully use the correct parts for partial recovery, which can improve the tolerance for errors in computations. Decoding is performed only when the verification result satisfies the permission, which avoids repetitive decoding. We conduct extensive simulation experiments to evaluate the probability of successful recovery of the results and the computation time of the TD scheme. We also compare the TD scheme with other verification schemes and the results show that it outperforms the current schemes in terms of efficiency in verifying and recovering computational results.

Alibaba Cloud's preemptible instances are IaaS instances sold using an auction, similar to the spot instances offered by Amazon Web Services (AWS). Clients purchase them by bidding. The instances are terminated when supply is insufficient, or when the client's bid is lower than the "market price"- which Alibaba Cloud publishes ever so often. We collected Alibaba Cloud's preemptible price traces from November 2018 to July 2021. This work analyzes the traces, and shows evidence that they experienced sharp lateral behavioral changes over time. We characterize the traces before and after these events. Our analysis highlights features in the traces that seem to be artificially engineered by an underlying pricing mechanism. Since engineered features may abruptly change, they are particularly interesting to clients planning their bidding strategy, or scholars who study them (e.g., to design new pricing mechanisms on the basis of real-life data).

Tokenized Intelligence (TI) aims to enhance network performance by combining machine learning and blockchain-based tokenomics in software-defined networks (5G/6G). This paper examines the potential for incentivizing decentralized edge computing through economic rewards, which can facilitate the efficient training of AI models. TI enables the coordination of a decentralized network of nodes, which allows for collaborative sharing of resources and decreases the expenses linked to centralized cloud-based solutions. TI is utilized to design customized logical networks that effectively optimize the use of computing, storage, and networking resources within a common physical infrastructure. This framework, which is decentralized and distributed, speeds up data analysis and reduces delays. It also provides economic rewards for edge nodes that participate in model training activities. The core of TI lies in its ability to improve network slicing strategies, such as best effort, high availability, and low latency, while also incentivizing edge nodes based on their contributions to the training process of the machine learning model. This economic incentive mechanism guarantees the efficient allocation of resources according to the specific needs of machine learning applications, thereby enhancing overall network performance.

During the process of obtaining a point cloud, various problems, such as noise, occlusion, and incompleteness, will affect the recognition accuracy of the object. This paper proposes a point cloud 3D object recognition method combining SHOT features and ESF features to identify the objects in complex point cloud scenes accurately. The model is recognized based on the template matching method. According to the corresponding group and Hough voting method, we can determine the matching key points and the global features are calculated based on the rotation invariance characteristic of point clouds. The experiments show that the proposed method is, on average, 15% more accurate than traditional feature descriptor based on identification methods, and our approach also presents better robustness to noise.

Speech emotion recognition in affective computing is an area that is growing quickly. It has implications for how people and computers interact, how mental health is diagnosed, and how customer service is handled. To correctly pick up on emotions in real time, deep learning is used in this study. Our model looks at vocal pitch, tone, and cadence along with complicated neural network designs to accurately classify emotions. The method was taught with a variety of emotional expressions. It's strong and can work with a wide range of speakers and settings. Many tests show that the model is more accurate and can process emotions faster than most other ways. Deep learning can make automatic systems smarter about emotions, which can make them more caring and flexible, as this study shows
