System and process for a fusion classification for insurance underwriting suitable for use by an automated system
A method and system for fusing a collection of classifiers used for an automated insurance underwriting system and/or its quality assurance is described. Specifically, the outputs of a collection of classifiers are fused. The fusion of the data will typically result in some amount of consensus and some amount of conflict among the classifiers. The consensus will be measured and used to estimate a degree of confidence in the fused decisions. Based on the decision and degree of confidence of the fusion and the decision and degree of confidence of the production decision engine, a comparison module may then be used to identify cases for audit, cases for augmenting the training/test sets for re-tuning production decision engine, cases for review, or may simply trigger a record of its occurrence for tracking purposes. The fusion can compensate for the potential correlation among the classifiers. The reliability of each classifier can be represented by a static or dynamic discounting factor, which will reflect the expected accuracy of the classifier. A static discounting factor is used to represent a prior expectation about the classifier's reliability, e.g., it might be based on the average past accuracy of the model, while a dynamic discounting is used to represent a conditional assessment of the classifier's reliability, e.g., whenever a classifier bases its output on an insufficient number of points it is not reliable. |

A hardware and software implemented, standardize testing, scoring and reporting system has a network interface, being either LAN or the Internet. A test is selected from a library, assigned to a group of examinees, and a record is made of the assignment. The test is available on-line, or downloaded, or both. Downloaded tests are saved as PDF files and printed into booklets. Examinees record answers on bubble sheets, which are scanned at the customer site or shipped to a processing plant. Individual scanned answer sheets provided data for individual scanned records. Scanning software performs an initial auto-correct and then performs an initial check for errors in scanned records. Tests are batched for later inspection. Scanned records with errors are classified as invalid and the test papers are separated. Prompts are generated for a human test paper inspection and scanned record editing. Accepted batches of scanned records are sent to a scanned records server where a second scanned records error check is performed. Prompts are sent to the appropriate scanning station for further human editing of invalid scanned records. Once all records are valid they are scored and the test results stored in a database, which is accessed by a reporting subsystem associated with an on-line server. |

Watermarking of motion pictures
The problem of watermarking a sequence of images from a motion picture can be divided into two parts. The first part is embedding watermarks in the sequence of images. The second part is detecting embedded watermarks in a target sequence of images where the target sequence may have resulted from one or more attacks on an original sequence of images in which the watermarks were embedded. Motion pictures are watermarked by embedding information in different ways in different images. In general, the information to be embedded is used to define a plurality of watermark images. Each watermark image is an apparent pattern of noise in both signal and frequency domains, and is different from the other watermark images. Preferably, each watermark image is temporally uncorrelated with the other watermark images. Each watermark image is used to modify a corresponding image from the motion picture. To detect the presence of the information in a target sequence of images from a motion picture, the target images are processed to determine an alignment with a watermark sequence. When an alignment with the watermark sequence is determined, a sliding window detector is applied to detect the watermark and read the information embedded by the watermark. By embedding the same information in different ways in different images, and then detecting this information by combining data from the different images, the sensitivity of the detector is increased. |

This invention is a method for binaural localization using a cascade of resonators and anti-resonators to implement an HRTF (head-related transfer function).

Finally, the method offers additional flexibility since the resonators and anti-resonators can be manipulated individually during the design process, making it possible to interpolate smoothly between HRTFs, reduce spectral coloring or achieve higher accuracy at perceptually relevant frequency regions. These HRTF are useful in stereo enhancement and multi-channel virtual surround simulation. |

Bitrate reduction techniques for image transcoding
This disclosure describes techniques for encoding data to compress image data to a reduced size. The techniques may be particularly effective in transcoding an image to a reduced size for transmission. An encoding device may transcode an image to an acceptable file size using bitrate control techniques that affect the entire image uniformly to transcode the image. For example, the encoding device may modify one or more quantization tables as a function of the near linear relationship between bitrate (R) and the number of zero-valued quantized transform coefficients to reduce the file size uniformly over the entire image. Alternatively, or additionally, the encoding device may transcode the image using bitrate control techniques that affect only specific localized regions of the image. |

Channel estimation method operable to cancel a dominant disturber signal from a received signal
A processing module produces improved main channel estimate. This process involves initially estimating the channel impulse response. This result is based on and combined with a known sequences such as that provided by training sequences of the midamble within RF bursts. From this combination, it is possible to produce an estimated signal from a convolution of the channel impulse response and midamble. The estimated signal may be cancelled or subtracted from the received signal to produce a clearer image of the disturber signal. A blind data recovery performed upon the disturber signal. The recovered disturber data may be used as a reference for disturber channel estimation in order to produce a disturber channel impulse response. With the estimated disturber channel impulse response and the recovered disturber data, an estimated disturber signal may be reconstructed and subtracted from the received signal. This allows the cancellation of the estimated disturber signal. Without a clear or dominant disturber signal, a better representation of the main channel impulse response may be produced. This results in more accurate processing of the received RF bursts and improved receiver performance. |

Optimized scheduling method using ordered grants from a central controller
A method, system, and computer program product for ordering grants of upstream bandwidth in a two-way grant-based communication system, such as a DOCSIS-based communication system. Typically, a central controller, such as a CMTS, sends a grant message to a set of end user devices, e.g., cable modems, wherein the message defines when each end user device can transmit upstream. The invention first determines, for each end user device, the time needed for processing the grant message. The central controller then constructs the grant message, such that grants for the end user devices associated with the shortest grant message processing times occur early in the grant message and represent the earliest grants. Grants for end user devices associated with the longest grant message processing times occur later in the grant message and represent later grants. With this ordering of grants within the grant message, the CMTS can assume a smaller processing time for processing the grant message by CMs, such that the grant message does not have to be sent so far in advance. Performance of the system is increased due to decreased roundtrip delay. |

Method to support lossless real time data sampling and processing on rapid I/O end-point
A serial buffer monitors an incoming stream of packets to identify single missing packets and multiple consecutive missing packets. Upon detecting multiple consecutive missing packets, an interrupt is generated, thereby stopping the data transfer. Upon detecting a single missing packet, a single missing packet identifier is inserted into the packet header of the packet that resulted in identification of the single missing packet. The incoming packets, including any inserted single missing packet identifiers, are written to a queue. When the water level reaches the water mark of the queue, the stored packets are read to create an outgoing packet stream. When a packet read from the queue includes an inserted single missing packet identifier, a dummy packet (e.g., a packet having a data payload of all zeros) is inserted into the outgoing packet stream. As a result, real-time applications are capable of processing the outgoing packet stream in a constant fashion. |
