A unified context-aware content archive system allows enterprises to manage, enforce, monitor, moderate, and review business records associated with a variety of communication modalities. The system may store an information infoset derived or inferred from one or more documents representing communications according to the variety of communication modalities as interaction transcripts. An interaction transcript represents interactions between participants through the documents rather than the documents themselves allowing for derivation or inference of communication events, chronologies, and mappings to be stored in a common data structure. In one aspect, events correlation is provided between participants of communications that can be established by general time series analysis for the purposes of extracting meaningful statistics and interaction contexts and other characteristics of data. In another aspect, chronological mappings are provided of conversations between an established start and end time frame.

A database has chronologically ordered images classified into event groups based upon a time difference threshold, and into subgroups based upon a similarity measure. In a method and system for combining new images into such a database, new image are ordered into clusters based upon assessed image features. A representative image is selected in each cluster. A database segment chronologically overlapping the new images is designated and a set of database images similar to each representative image are identified in the segment. Different subgroups including one or more retrieved images are associated with each of cluster to provide matched subgroups. The new images are assigned to matched subgroups associated with respective clusters.

An apparatus and method for capturing and organizing information spatio-temporally utilizes a standardized time reference and geographical locations to associate a time and a place to each event that is captured. These events are placed in a coordinate system according to the associated times and places. The apparatus and method may use a meridial clock. A series of related events forms an event path that progresses chronologically. Plural event paths are illustrated in a coordinate system based image of a user interface. Events from different event paths are synchronized so that events that occur in a particular moment are placed in the same time plane. As time progresses, the events emit from the plane into a region representing the past, and a relationship of events with their times and places is illustrated. A map in the plane of the image may facilitate visualization of places and times with events.

Estimating a location of a first mobile communication unit (220) in a cellular wireless communications system (200) comprises comparing a first signature from the first mobile communication unit with known signatures. The first signature may comprise control information, a set of observable cells and received power level information for the first mobile communication unit (220). A location estimate is provided from the known location of a known signature in a database (410), if that known signature matches the first signature. The comparison may be a correlation to determine the degree of matching. Context information may link two or more known signatures in the database (410), the known signatures having been obtained in temporal succession from one mobile device (258) in use in the system. The context information may be used in the comparison.

Described is a system for representing, storing, and reconstructing an input signal. The system constructs an index of unique polychronous groups (PCGs) from a spiking neuron network. Thereafter, a basis set of spike codes is generated from the unique PCGs. An input signal can then be received, with the input signal being spike encoded using the basis set of spike codes from the unique PCGs. The input signal can then be reconstructed by looking up in a reconstruction table, for each unique PCG in the basis set in temporal order according to firing times, anchor neurons. Using a neuron assignment table, an output location can be looked up for each anchor neuron to place a value based on the firing times of each unique PCG. Finally, the output locations of the anchor neurons can be compiled to reconstruct the input signal.

The present invention discloses an express way traffic state prediction method taking spatial-temporal correlation into account at different times. The method comprises: firstly, performing analysis period dynamic division of flow, speed and time sequences through adoption of a sequential cluster, and dividing the whole day into analysis periods with different traffic characteristics without disturbing traffic parameter time sequences; and selecting multivariable vector autoregression models aiming at different periods, comprehensively considering the spatial-temporal correlation of the upstream and downstream traffic flows, and predicting the flow or the speed of target places. The dynamic period division of the express way traffic state prediction method taking spatial-temporal correlation into account at different times provides a cheap, easy and substantially improved efficiency basic method for express way traffic state short-time prediction; and compared with a traditional method without considering the upstream and downstream traffic flow influence, the express way traffic state prediction method taking spatial-temporal correlation into account at different times considers the vector autoregression model of the spatial-temporal correlation after the periods are divided, so that the prediction results are obviously improved in precision.

Certain example embodiments provide a single pass, reverse chronological approach to write-ahead log recovery, enabling space- and time-efficient the recovery of stored data from large write-ahead logs to a transient storage medium. The techniques described herein can in certain instances enable fast and efficient recovery, even in scenarios where at the time of a failure requiring such a recovery the live log is potentially multiple terabytes or larger in size. Certain example embodiments make use of a filtering mechanism (e.g., involving potentially stateful delete, skip, and / or transaction filters), a key / value property (allowing a live set of data, once identified, to be applied in any arbitrary order), etc. A simplified environment with a small closed set of mutative operations allows for the performing of recovery backwards by scanning the log from the most recent written record backwards in time (and, in other words, finishing with the oldest record).

Systems and methods for unsupervised representation learning by sorting sequences are provided. An unsupervised representation learning approach is provided which uses videos without semantic labels. The temporal coherence as a supervisory signal can be leveraged by formulating representation learning as a sequence sorting task. A plurality of temporally shuffled frames (i.e., in non-chronological order) can be used as inputs and a convolutional neural network can be trained to sort the shuffled sequences and to facilitate machine learning of features by the convolutional neural network. Features are extracted from all frame pairs and aggregated to predict the correct sequence order. As sorting shuffled image sequence requires an understanding of the statistical temporal structure of images, training with such a proxy task can allow a computer to learn rich and generalizable visual representations from digital images.
