Data-driven problem solving in many real-world applications involves analysis of time-dependent multivariate data, for which dimensionality reduction (DR) methods are often used to uncover the intrinsic structure and features of the data. However, DR is usually applied to a subset of data that is either single-time-point multivariate or univariate time-series, resulting in the need to manually examine and correlate the DR results out of different data subsets. When the number of dimensions is… 
Exploring Multi‐dimensional Data via Subset Embedding
This paper proposes a visual analytics approach to exploring subset patterns using a subset embedding network that represents a group of subsets as uniformly‐formatted embeddings and demonstrates the general applicability and effectiveness of the approach.
A Visual Analytics Approach for the Diagnosis of Heterogeneous and Multidimensional Machine Maintenance Data
This work adopts existing techniques for dimensionality reduction and clustering of numerical, categorical, and text data dimensions, and introduces a visual analytics approach that uses multiple coordinated views to connect DR + clustering results across each kind of the data dimension stated.
Guided Stable Dynamic Projections
Two dynamic projection methods are proposed that use global guides to steer projection points and score a good balance between stability, neighborhood preservation, and distance preservation, while LD‐tSNE allows creating stable and customizable projections.

This work proposes a multi-level visual analysis method based on the K-Means algorithm, which can better understand user behaviors from multiple community granularity and multiple time scales, and designs and improves three traditional charts that can help analysts observe user characteristics at the three levels.
OutViz: Visualizing the Outliers of Multivariate Time Series
OutViz is proposed, a dual view framework for representing and filtering multivariate time series data to highlight abnormal patterns in a dataset that allows the user to analyze the scores of features extracted from a dimensionality reduction density-based clustering outlier detection algorithm to determine why a particular time series is predicted to be an outlier.
Visual Analysis of Industrial Multivariate Time Series
The recent development in the data analytics field provides a boost in production for modern industries. Small-sized factories intend to take full advantage of the data collected by sensors used in
A Visual Analytics Approach for Hardware System Monitoring withStreaming Functional Data Analysis
This paper introduces new incremental and progressive algorithms that promptly generate the magnitude-shape (MS) plot, which conveys both the functional magnitude and shape outlyingness of time series data, and enhances the analyst’s ability to investigate the visually-identified outliers.
A Visual Analytics Approach to Monitor Time-Series Data with Incremental and Progressive Functional Data Analysis
This paper presents a visual analytics approach to consecutively monitor and review the changing time-series data with a focus on identifying outliers by using FDA, and introduces new incremental and progressive algorithms that promptly generate the magnitude-shape (MS) plot, which reveals both the functional magnitude and shape outlyingness of time- series data.


Supporting Analysis of Dimensionality Reduction Results with Contrastive Learning
This work presents a visual analytics method that effectively highlights the essential features of a cluster in a DR result and introduces an enhanced usage of contrastive principal component analysis (cPCA), called ccPCA (contrasting clusters in PCA).
Temporal MDS Plots for Analysis of Multivariate Data
The proposed Temporal Multidimensional Scaling (TMDS) is a novel visualization technique that computes temporal one-dimensional MDS plots for multivariate data which evolve over time and enable visual identification of patterns based on multidimensional similarity of the data evolving over time.
An Incremental Dimensionality Reduction Method for Visualizing Streaming Multidimensional Data
This paper enhances an existing incremental PCA method in several ways to ensure its usability for visualizing streaming multidimensional data and uses geometric transformation and animation methods to help preserve a viewer's mental map when visualizing the incremental results.
Visualizing Time-Dependent Data Using Dynamic t-SNE
This work proposes dynamic t-SNE, an adaptation of t- SNE that introduces a controllable trade-off between temporal coherence and projection reliability, and evaluation in two time-dependent datasets shows that this adaptation eliminates unnecessary temporal variability and encourages smooth changes between projections.
Visual Interaction with Dimensionality Reduction: A Structured Literature Analysis
This work systematically studied the visual analytics and visualization literature to investigate how analysts interact with automatic DR techniques, and proposes a “human in the loop” process model that provides a general lens for the evaluation of visual interactive DR systems.

An overview of FDA is provided, starting with simple statistical notions such as mean and covariance functions, then covering some core techniques, the most popular of which is Functional Principal Component Analysis (FPCA), an important dimension reduction tool and in sparse data situations can be used to impute functional data that are sparsely observed.
Visualizing Data using t-SNE
We present a new technique called “t-SNE” that visualizes high-dimensional data by giving each datapoint a location in a two or three-dimensional map. The technique is a variation of Stochastic
