Overview of Orientation Regularized Network (ORN)
Orientation Regularized Network (ORN) is a technique used for pose estimation that allows for the fusion of multiple views of an object in order to gain a more accurate understanding of its orientation. Specifically, ORN makes use of IMU orientations as a structural prior to mutually fuse the image features of each pair of joints linked by IMUs. This allows for the fusion of the features of the elbow to reinforce the ones found at the wrist for

Outlier Detection: Identifying Anomalous Data Points
Outlier detection is a tool used to identify unusual data points in a given set. These anomalous instances are different from other points and can provide important insights into the dataset. For example, outlier detection can be used in the security field to identify potential threats, or in manufacturing to detect parts that are likely to fail. Outlier detection is a core task of data mining and is widely used in many applications.

Packed Levitated Markers: An Innovative Approach for Named Entity Recognition
Named entity recognition (NER) is an important task in natural language processing (NLP) which involves identifying entities such as persons, organizations, locations, and dates in text. However, NER can be a challenging task, particularly if the entities overlap with each other. In such cases, traditional NER methods may not be sufficient to accurately identify all the named entities in the text. This is where Packed
Overview of PAFNet: A Revolutionary Anchor-Free Object Detection System
