Micro-Macro Views for Visual Trajectory Cluster Analysis
نویسندگان
چکیده
The scatter view shows the distribution of items on the high-resolution grid in relation to the trajectory clusters using a dot representation. The density view visualizes the sample distribution density in a color coded heatmap representation. Alternative heatmaps show the quantization error, the U-Matrix, etc. The star view is a connector-based view which indicates for each data sample its nearest cluster prototype on the original (coarse) SOM grid.

Incremental Clustering for Trajectories
Trajectory clustering has played a crucial role in data analysis since it reveals underlying trends of moving objects. Due to their sequential nature, trajectory data are often received incrementally, e.g., continuous new points reported by GPS system. However, since existing trajectory clustering algorithms are developed for static datasets, they are not suitable for incremental clustering wit...
متن کاملGravity-Compensated Robust Control for Micro-Macro Space Manipulators During a Rest to Rest Maneuver
Many space applications require robotic manipulators which have large workspace and are capable of precise motion. Micro-macro manipulators are considered as the best solution to this demand. Such systems consist of a long flexible arm and a short rigid arm. Kinematic redundancy and presence of unactuated flexible degrees of freedom, makes it difficult to control micro-macro manipulators. This ...
متن کاملEvaluation of cultivated and wild barley cultivars affinities using micro and macro-morphological traits of grain, pollen, and stomata. Sayyedh Masomeh Hosseini 1*, Mahlagh Ghorbanli 2 and Hossein Sabouri 3
In an ongoing research, 24 cultivated and wild cultivars of barley were evaluated for morphological characteristics of grain, pollen, and stomata. Traits of interest included length, width, and area. Results of variance analysis showed that all samples were differed in traits of stomata, grain, and pollen at probability levels of 1 and 5%, suggesting remarkable genetic variation among studied s...
متن کاملIBVis: Interactive Visual Analytics for Information Bottleneck Based Trajectory Clustering
Analyzing trajectory data plays an important role in practical applications, and clustering is one of the most widely used techniques for this task. The clustering approach based on information bottleneck (IB) principle has shown its effectiveness for trajectory data, in which a predefined number of the clusters and an explicit distance measure between trajectories are not required. However, pr...
متن کاملKinematic Analysis of a Macro-Micro Redundantly Actuated Parallel Manipulator
In this paper the kinematic and Jacobian analysis of a macro–micro parallel manipulator is studied in detail. The manipulator architecture is a simplified planar version adopted from the structure of the Large Adaptive Reflector (LAR), the Canadian design of the next generation of giant radio telescopes. This structure is composed of two parallel and redundantly actuated manipulators at the mac...
