This paper introduces to the calculus of regular expressions, the operators of unconditional and conditional parallel replacement as an enhancement of the existing replace operator (Karttunen 1995). It defines a set of replacement expressions that concisely encode several alternate variations of the operation. Replace expressions denote regular relations, defined in terms of other regular-expression operators. The basic case is unconditional obligatory replacement. Different versions of conditional replacement allow the operation to be constrained by context. All described replacement operations are now included in the Xerox finite-state calculus.

VISION
The research we conduct on expressive visual representations is applicable to visual search, object detection, image classification and the automatic extraction of 3D human poses and shapes that can be used for human behavior understanding and prediction, human-robot interaction or even avatar animation. We also extract 3D information from images that can be used for intelligent robot navigation, augmented reality and the 3D reconstruction of objects, buildings or even entire cities.
Our work covers the spectrum from unsupervised to supervised approaches, and from very deep architectures to very compact ones. We’re excited about the promise of big data to bring big performance gains to our algorithms but also passionate about the challenge of working in data-scarce and low-power scenarios.
Furthermore, we believe that a modern computer vision system needs to be able to continuously adapt itself to its environment and to improve itself via lifelong learning. Our driving goal is to use our research to deliver embodied intelligence to our users in robotics, autonomous driving, via phone cameras and any other visual means to reach people wherever they may be.
