The search for a true position solution is conducted either in phase ambiguity space or in three-dimensional geometric space. The two algorithms are tested, using both single- and dual-frequency carrier phase m
To prepare the radar data for tracking, we run a series of signal processing operations to distinguish static detections (such as guardrails) from dynamic detections (such as other vehicles), as well as filter ghosts caused by multipath reflections. We then apply a density-based spat...

For example, Yu, Wang and Guo (2018) proposed convex optimisation for optimising processing capability and Newton algorithm for transmission power [131]. The authors of [152] proposed a deep reinforcement learning for resource allocation and adopt gradient descent to train the parameters. 7. Root ...
processing. These systems typically target a bandwidth of 0.5-40 Hz. This is sufficient for preserving the key features of the ECG waveform, while also easing implementation on embedded hardware. This range aligns with reduced fidelity requirements in IEC 60601-2-47 for wearable or monitoring ...
The solution proposed is to develop notation that can be understood by computers, which do not tolerate ambiguity: “One way to become aware of the precision required to unambiguously communicate a mathematical idea is to program it for a computer. Rather than using canned programs purely as an...
Table 3 The mathematical formulas for random forest Full size table Logistic regression is a statistical technique that utilizes the sigmoid function as its fundamental method. It is commonly employed in machine learning to construct models when the target variable is binary, such as determining whethe...
HP-ELM includes GPU acceleration and memory optimization, which is suitable for large data processing. HP-ELM supports LOO (Leave One Out) and k-fold cross-validation to dynamically select the number of hidden layer nodes. The available feature maps include linear function, Sigmoid function, ...
An array would need an element for every possible value of a character. This would amount to a relatively reasonable 128 elements if you were processing ASCII strings, but if you had to process Unicode strings you would need more than 65,000 elements, assuming a 16-bit Unicode encoding. In...
The 3D acquisition and information processing technology reflects the ability of human beings to cognize and grasp the objective world, so to some extent it is an important symbol of human wisdom. Conventional cameras and imaging detectors can only acquire 2D intensity information of the scene but ...
