Adaptive Edge-to-Edge Interaction Learning for Point Cloud Analysis
Recent years have witnessed the great success of deep learning on various
point cloud analysis tasks, e.g., classification and semantic segmentation.
Since point cloud data is sparse and irregularly distributed, one key issue for
point cloud data processing is extracting useful information from local
regions. To achieve this, previous works mainly extract the points' features
from local regions by learning the relation between each pair of adjacent
points. However, these works ignore the relation between edges in local
regions, which encodes the local shape information. Associating the
neighbouring edges could potentially make the point-to-point relation more
aware of the local structure and more robust. To explore the role of the
relation between edges, this paper proposes a novel Adaptive Edge-to-Edge
Interaction Learning module, which aims to enhance the point-to-point relation
through modelling the edge-to-edge interaction in the local region adaptively.
We further extend the module to a symmetric version to capture the local
structure more thoroughly. Taking advantage of the proposed modules, we develop
two networks for segmentation and shape classification tasks, respectively.
Various experiments on several public point cloud datasets demonstrate the
effectiveness of our method for point cloud analysis.Comment: Technical Repor
Investigation and Research on Physical Education and Health Curriculum of K-12 School in Guizhou Province
The purpose of this study is to investigate the current situation of physical education and health curriculum in primary and secondary schools in Guizhou Province, and to provide reference for promoting the better implementation of physical education and health curriculum in Guizhou Province. In the form of questionnaires, 1549 parents\u27 questionnaires and 254 teachers\u27 questionnaires were collected and statistically analyzed in Guizhou Province, China. Use Excel to summarize and analyze the collected questionnaires. The results found the teaching content could basically meet the needs of students. The satisfaction of primary school students, junior high school students and senior high school students with physical education and health curriculum evaluation was 71.6%, 68.4% and 63.6%, respectively. Students\u27 satisfaction with the content of physical education and health curriculum in senior high school decreased; both students and teachers believed that all students had the opportunity to participate in sports activities in physical education and health classes, but the time for skill learning and physical training in PE classes in primary and secondary schools was less than 20 minutes. The intensity of classroom exercise in 60% of primary and secondary schools was less than 75%. 94.1% of teachers control exercise load according to experience, and only 3.9% of schools use intelligent monitoring devices to monitor. 50.9% of primary and junior high school physical education classes did not meet the required number of class hours. 69.6% of the students were satisfied with the elective items in the physical education courses offered, but their satisfaction with the senior high school dropped to 61.6%. Primary and secondary schools in Guizhou Province should continue to increase the construction and investment of physical education and health curriculum venues, equipment and facilities, and optimize the use and development of existing physical education curriculum resources. Physical education teachers should constantly update teaching concepts, improve teaching methods and improve course teaching ability. Schools and teachers should carry out physical education and health courses according to the requirements of physical Education and Health Curriculum Standards, and actively promote the Chinese Health physical Education Curriculum Model put forward by JI Liu professor to ensure a certain exercise load and exercise density
Adaptive Pattern Extraction Multi-Task Learning for Multi-Step Conversion Estimations
Multi-task learning (MTL) has been successfully used in many real-world
applications, which aims to simultaneously solve multiple tasks with a single
model. The general idea of multi-task learning is designing kinds of global
parameter sharing mechanism and task-specific feature extractor to improve the
performance of all tasks. However, challenge still remains in balancing the
trade-off of various tasks since model performance is sensitive to the
relationships between them. Less correlated or even conflict tasks will
deteriorate the performance by introducing unhelpful or negative information.
Therefore, it is important to efficiently exploit and learn fine-grained
feature representation corresponding to each task. In this paper, we propose an
Adaptive Pattern Extraction Multi-task (APEM) framework, which is adaptive and
flexible for large-scale industrial application. APEM is able to fully utilize
the feature information by learning the interactions between the input feature
fields and extracted corresponding tasks-specific information. We first
introduce a DeepAuto Group Transformer module to automatically and efficiently
enhance the feature expressivity with a modified set attention mechanism and a
Squeeze-and-Excitation operation. Second, explicit Pattern Selector is
introduced to further enable selectively feature representation learning by
adaptive task-indicator vectors. Empirical evaluations show that APEM
outperforms the state-of-the-art MTL methods on public and real-world financial
services datasets. More importantly, we explore the online performance of APEM
in a real industrial-level recommendation scenario.Comment: 18 pages, 9 figure
Advances in oncolytic herpes simplex virus and adenovirus therapy for recurrent glioma
Recurrent glioma treatment is challenging due to molecular heterogeneity and treatment resistance commonly observed in these tumors. Researchers are actively pursuing new therapeutic strategies. Oncolytic viruses have emerged as a promising option. Oncolytic viruses selectively replicate within tumor cells, destroying them and stimulating the immune system for an enhanced anticancer response. Among Oncolytic viruses investigated for recurrent gliomas, oncolytic herpes simplex virus and oncolytic adenovirus show notable potential. Genetic modifications play a crucial role in optimizing their therapeutic efficacy. Different generations of replicative conditioned oncolytic human adenovirus and oncolytic HSV have been developed, incorporating specific modifications to enhance tumor selectivity, replication efficiency, and immune activation. This review article summarizes these genetic modifications, offering insights into the underlying mechanisms of Oncolytic viruses’ therapy. It also aims to identify strategies for further enhancing the therapeutic benefits of Oncolytic viruses. However, it is important to acknowledge that additional research and clinical trials are necessary to establish the safety, efficacy, and optimal utilization of Oncolytic viruses in treating recurrent glioblastoma
