SEQ2SEQ-VIS : A visual debugging Tool for Sequence-to-Sequence Models

IEEE TRANSACTIONS ON visualIZATION AND COMPUTER GRAPHICS 2019年第1期25卷 353-363页

Neural sequence-to-sequence models have proven to be accurate and robust for many sequence prediction tasks, and have become the standard approach for automatic translation of text. The models work with a five-stage blackbox pipeline that begins with encoding a source sequence to a vector space and then decoding out to a new target sequence. This process is now standard, but like many deep learning methods remains quite difficult to understand or debug. In this work, we present a visual analysis tool that allows interaction and "what if"-style exploration of trained sequence-to-sequence models through each stage of the translation process. The aim is to identify which patterns have been learned. to detect model errors, and to probe the model with counterfactual scenario. We demonstrate the utility of our tool through several real-world sequence-to-sequence use cases on large-scale models.

Regular expressions are a widely used programming technique, but seem to be neglected by software engineering research. Encoding complex string parsing in a very compact notation, their complexity and compactness, however, introduce particular challenges with respect to program comprehension. In this paper, we present RegViz, an approach to visually augment regular expressions without changing their original textual notation. The visual encoding clarifies the structure of the regular expressions and clearly discerns included tokens by function. The approach also provides advanced visual highlighting of matches in a sample text and defining test cases therein. We implemented RegViz as a Web-based tool for JavaScript regular expressions. Expert feedback suggests that the approach is intuitive to apply and increases the readability of regular expressions.

This paper presents a novel use of visualization applied to debugging the Cplant(TM) cluster hardware at Sandia National Laboratories, As commodity cluster systems grow in popularity and grow in size, tracking component failures within the hardware will become more and more difficult, We have developed a tool that facilitates visual debugging of errors within the switches and cables connecting the processors. Combining an abstract system model with color-coding for both error and job information enables failing components to be identified.

Applying Information visualization Techniques to visual debugging

Applying Information Visualization Techniques to Visual Debu...

作者： Costigan, John A. Virginia Tech | University

In the arena of software development, implementing a software design (no matter how perfect the design) is rarely done right the first time. Consequently, debugging one’s own (or someone else’s) software is inevitable, and tools that assist in this often-arduous task become very important with respect to reducing the cost of debugging as well as the cost of the software life cycle as a whole. Many tools exist with this aim, but all are lacking in a key area: information visualization. Applying information visualization techniques such as zooming, focus and context, or graphical representation of numeric data may enhance the visual debugging experience. To this end, drawing data structures as graphs is potentially a step in the right direction, but more must be done to maximize the value of time spent debugging and to minimize the actual amount of time spent debugging. This thesis will address some information visualization techniques that may be helpful in debugging (specifically with respect to visual debugging) and will present the results of a small pilot study intended to illustrate the potential value of such techniques.

We present an innovative application developed at Sandia National Laboratories for visual debugging of unstructured finite element physics codes. Our tool automatically locates anomalous regions, such as inverted elements or nodes whose variable values lie outside a prescribed range, then extracts mesh subsets around these features for detailed examination. The subsets are viewed using color coding of variable values superimposed on the mesh structure. This allows the values and their relative spatial locations within the mesh to be correlated at a glance. Both topological irregularities and hot spots within the data stand out visually, allowing the user to explore the exact numeric values of the grid at surrounding points over time. We demonstrate the utility of this approach by debugging a cell inversion in a simulation of an exploding wire.

A Unified Understanding of Deep NLP Models for Text Classification

IEEE TRANSACTIONS ON visualIZATION AND COMPUTER GRAPHICS 2022年第12期28卷 4980-4994页

The rapid development of deep natural language processing (NLP) models for text classification has led to an urgent need for a unified understanding of these models proposed individually. Existing methods cannot meet the need for understanding different models in one framework due to the lack of a unified measure for explaining both low-level (e.g., words) and high-level (e.g., phrases) features. We have developed a visual analysis tool, DeepNLPVis, to enable a unified understanding of NLP models for text classification. The key idea is a mutual information-based measure, which provides quantitative explanations on how each layer of a model maintains the information of input words in a sample. We model the intra- and inter-word information at each layer measuring the importance of a word to the final prediction as well as the relationships between words, such as the formation of phrases. A multi-level visualization, which consists of a corpus-level, a sample-level, and a word-level visualization, supports the analysis from the overall training set to individual samples. Two case studies on classification tasks and comparison between models demonstrate that DeepNLPVis can help users effectively identify potential problems caused by samples and model architectures and then make informed improvements.

A FRAMEWORK FOR THE AUTOMATED DRAWING OF DATA STRUCTURE DIAGRAMS

Data structure diagrams are two-dimensional figures made up of lines that aim to pictorially indicate the interrelationships of the elements of a data structure. The various rules and factors of aesthetics that go into the way data structure diagrams are drawn are collected together. The various subjective factors are formulated into computable objectives and numeric parameters. These are distilled from a large number of data structure drawings found in various textbooks. The rules used have not reached a level of acceptance comparable to that of the relevant rules in engineering graphics. The internal architecture of a (sub)system that helps draw data structure diagrams is outlined.

***: visual test and debug queries for hard real-time

Hard real-time systems have stringent timing and resource requirements. As such, debugging and tracing such systems often requires low-level hardware support, and online debugging is usually precluded entirely. In other areas, however, visual debugging has greatly improved program understanding and late cycle development times for nonreal-time applications. In this paper, we introduce a visual test and debug framework for hard real-time Java applications built around the JIVE platform and realized in the Fiji virtual machine. Our framework, called *** ["dZIfi], provides high-level debugging support over low-level execution traces. *** provides both powerful visualizations and real-time centric temporal query support. To ensure preservation of the real-time characteristics of the application being tested and debugged, *** leverages a real-time event log infrastructure that logs only relevant application and virtual machine level events, such as synchronization and modifications to priorities or thread state. Our performance results indicate that our logging infrastructure is suitable for hard real-time systems, as the performance impact is both uniform and quantifiable.

This half-day tutorial gives an overview of the current state-of-the-art in software visualization. Software visualization encompasses the development and evaluation of methods for graphically representing different aspects of software, including its structure, its execution, and its evolution. In contrast to visual programming and diagramming for software design, software visualization is not so much concerned with the construction, but with the analysis of programs and their development process. Software visualization combines techniques from areas like software engineering, programming languages, data mining, computer graphics, information visualization and human-computer interaction. Topics covered in this tutorial include static program visualization, algorithm animation, visual debugging, as well as the visualization of the evolution of software. In particular we identify common principles illustrated by many examples and give pointers to tools available today.
