Neural Baby Talk

Abstract: We introduce a novel framework for image captioning that can produce natural language explicitly grounded in entities that object detectors find in the image. Our approach reconciles classical slot filling approaches (that are generally better grounded in images) with modern neural captioning approaches (that are generally more natural sounding and accurate). Our approach first generates a sentence `template' with slot locations explicitly tied to specific image regions. These slots are then filled in by visual concepts identified in the regions by object detectors. The entire architecture (sentence template generation and slot filling with object detectors) is end-to-end differentiable. We verify the effectiveness of our proposed model on different image captioning tasks. On standard image captioning and novel object captioning, our model reaches state-of-the-art on both COCO and Flickr30k datasets. We also demonstrate that our model has unique advantages when the train and test distributions of scene compositions -- and hence language priors of associated captions -- are different.

Adaptive hypermedia presentation method and system

Abstract: In a computer system comprising a hypermedia computing environment, the presentation of hypermedia objects is adapted to usage of the system. The frequency with which hypermedia objects are used is tracked and the objects are ordered such that the most frequently used hypermedia objects are made most accessible. The system also adapts to user characteristics such as user experience level, user disabilities and user preferences. For example, hypermedia objects inappropriate for beginner users are not displayed when a novice is using the system. Further, visual hypermedia objects are ordered ahead of audio hypermedia object for hearing impaired users.

Object oriented mail server framework mechanism

Abstract: A framework for use with object-oriented programming systems provides a common message processing system structure that can be placed on any OOP platform and be configured to support any e-mail message protocol standard or specific mail server function. The framework defines an e-mail message as a number of distinct objects, each of which contains information that describes some portion of the message. All messages received by a system in which the framework is implemented are defined on this core object structure. Another set of objects and methods define the processing steps required for a mail server to process a message. A message is received as a class of message objects, which are assigned a message type that determines the subsequent processing steps to which the message object is subjected. As a message is processed, the objects of which it is comprised are changed, so that the message processing can be interrupted and then resumed without loss or duplication of processing steps.

Visual software engineering system and method for developing visual prototypes and for connecting user code to them

Abstract: A system for providing a simple, easy to learn and flexible means of creating user interfaces to products under development without the need of a programming language or the need to learn a large set of complicated commands. The Visual Software Engineering ("VSE") system of the invention uses a simple concept of defining both input to and output from graphical objects in an object-oriented system by providing examples of what the user desires the graphical object to do. This technique is referred to herein as "animation by example". In accordance with this process, the user creates a user interface by drawing the user interface with a graphics editor and then defining the output behavior (i.e., graphics manipulation) of the user interface components by showing each state or frame as an animation. This is accomplished by changing the object using a graphic editor function such as move or rotate and storing each of the frames with the object as a behavior state. Just as with defining the output, the input is defined by giving the graphic object an example of what type of input to look for, and once it finds that input, it tells the object which frame to output or change to. Application code can then drive the animation or read the input by accessing the frame numbers assigned to each of the example frames.

Typed closure conversion

Abstract: Closure conversion is a program transformation used by compilers to separate code from data. Previous accounts of closure conversion use only untyped target languages. Recent studies show that translating to typed target languages is a useful methodology for building compilers, because a compiler can use the types to implement efficient data representations, calling conventions, and tag-free garbage collection. Furthermore, type-based translations facilitate security and debugging through automatic type checking, as well as correctness arguments through the method of logical relations.We present closure conversion as a type-directed, and type-preserving translation for both the simply-typed and the polymorphic λ-calculus. Our translations are based on a simple "closures as objects" principle: higher-order functions are viewed as objects consisting of a single method (the code) and a single instance variable (the environment). In the simply-typed case, the Pierce-Turner model of object typing where objects are packages of existential type suffices. In the polymorphic case, more careful tracking of type sharing is required. We exploit a variant of the Harper-Lillibridge "translucent type" formalism to characterize the types of polymorphic closures.
