Hybrid On-Device Cloud Scheme for Re-Identification of Persons Based on Shared Embedding Gallery

Generally, the present disclosure is directed to a system of facial and/or person recognition via machine learning and Internet of Things (IoT). In particular, in some implementations, the systems and methods of the present disclosure can include or otherwise leverage a machine learning and IoT system or device to track and/or identify a person based on video images taken by one or more device(s). For example, a hybrid on-device and cloud scheme can enable locally-derived embeddings from multiple camera devices to be sent to a shared cloud space which can cluster the embeddings to generate a person model for a given person. Later, a camera device participating in the scheme can again detect a face and can match an embedding generated for the face against the shared gallery of person models to (potentially) re-identify the previously observed person

The MELD Programming Language: User Manual

This manual is divided into two parts, a tutorial introduction to the MELD programming language, and a language reference manual. The index spans both parts. A bibliography of MELD publications and technical reports is available in Appendix II. If you are interested in the decisions leading to the current design you should refer to this literature; the intent of this manual is to provide a working description of the current language and its implementation, and not an exposition of the language issues. Chapter 9 describes the language features which are not yet implemented

Interactive Device that Performs Output Based On Human Movement and/or Human Emotion Detected via Machine Learning

Generally, the present disclosure is directed to a device capable of providing an output that is specific to and/or based on nearby human movement and/or human emotion detected by one or more machine-learned models

A Framework for Sharing Handwritten Notes

NotePals is an ink-based, collaborative note taking application that runs on personal digital assistants (PDAs). Meeting participants write notes in their own handwriting on a PDA. These notes are shared with other participants by synchronizing later with a shared note repository that can be viewed using a desktop-based web browser. NotePals is distinguished by its lightweight process, interface, and hardware. This demonstration illustrates the design of two different NotePals clients and our web-based note browser.

Adaptive Remote Paging for Mobile Computers

There is a strong trend toward the production of small "notebook" computers. The small size of portable computers places inherent limits on their storage capacity, making remote paging desirable or necessary. Further, mobile computers can "walk away from" their servers, increasing load on network routing resources and/or breaking network connections altogether. Therefore, it is desirable to allow client-server matchups to be made dynamically and to vary over time, so that a client might always be connected to nearby servers. Accordingly, we have built a self-organizing paging service that adapts to changes in locale and that stores pages in remote memory if possible. We show empirically that there is no performance penalty for using our paging facility instead of a local disk. This suggests that portable computers need neither a hard disk nor an excessive amount of RAM, provided that they will operate in environments in which remote storage is plentiful. These are important facts becau..

Disseminating Active Map Information to Mobile Hosts

Mobile computing differs from desk-top computing because of the dynamic nature of system state: as users move, the sets of stationary and mobile objects they control and the types of information they wish to access change. Navigating a mobile environment can be aided by active maps that describe the location and characteristics of objects within some region as they change over time. We describe an active map service that keeps clients informed of changes in their environment. The primary issue driving our design is the question of scale: an active map service must be able to handle updates and queries over sufficiently large regions of space to satisfy clients' interests and must be able to handle peak loads that can occur when everyone in a region is moving around, for example, to attend a meeting. Our solution detects sets of clients that wish to receive the same active map information and then dynamically assigns multicast groups to them. To guarantee clients that they and the..

Digital Library Information Appliances

Although digital libraries are intended to support education and knowledge work, current digital library interfaces are narrowly focused on retrieval. Furthermore, they are de-signed for desktop computers with keyboards, mice, and high-speed network connections. Desktop computers fail to support many key aspects of knowledge work, including active reading, free form ink annotation, fluid movement among document activities, and physical mobility. This pa-per proposes portable computers specialized for knowledge work, or digitul librav information appliances, as a new platform for accessing digital libraries. We present a number of ways that knowledge work can be augmented and trans-formed by the use of such appliances. These insights are based on our implementation of two research prototype systems: XLibris, an “active reading machine, ” and Tele-Web, a mobile World Wide Web browser

Beyond Paper: Supporting Active Reading with Free Form Digital Ink Annotations

Reading frequently involves not just looking at words on a page, but also underlining, highlighting and commenting, either on the text or in a separate notebook. This combination of reading with critical thinking and learning is called active reading [2]. To explore the premise that computation can enhance active reading we have built the XLibris "active reading machine." XLibris uses a commercial high-resolution pen tablet display along with a paper-like user interface to support the key affordances of paper for active reading: the reader can hold a scanned image of a page in his lap and mark on it with digital ink. To go beyond paper, XLibris monitors the free-form ink annotations made while reading, and uses these to organize and to search for information. Readers can review, sort and filter clippings of their annotated text in a "Reader's Notebook." XLibris also searches for material related to the annotated text, and displays links to similar documents unobtrusively in the margin. XLibris demonstrates that computers can help active readers organize and find information while retaining many of the advantages of reading on paper.
