Abstract: A method of machine learning model development includes building an autoencoder including an encoder trained to map an input into a latent representation, and a decoder trained to map the latent representation to a reconstruction of the input. The method includes building an artificial neural network classifier including the encoder, and a classification layer partially trained to perform a classification in which a class to which the input belongs is predicted based on the latent representation. Neural network inversion is applied to the classification layer to find inverted latent representations within a decision boundary between classes in which a result of the classification is ambiguous, and inverted inputs are obtained from the inverted latent representations. Each inverted input is labeled with a class that is its ground truth, and thereby producing added training data for the classification, and the classification layer is further trained using the added training data.

Abstract: An electronic financial transaction system employing a cryptocurrency, the system includes: a user terminal for requesting an electronic financial transaction by a cryptocurrency registered by a user; and an exchange server which, upon a request from the user terminal, analyzes an amount of the cryptocurrency corresponding to a target price of the electronic financial transaction according to a real-time market price of the cryptocurrency registered by the user, and makes a payment of the electronic financial transaction by that said amount of the cryptocurrency. According to the present invention, a user can make an electronic financial transaction such as purchasing a product or a service by a holding cryptocurrency or exchanging the holding cryptocurrency for cyber money by applying a real-time market price without exchanging a cryptocurrency holding for investment for a fiat currency.

Abstract: A security tool is disclosed for predicting a sequence of events based on the current events observed. The security tool relies on sequential event mining algorithms to discover the baseline event patterns, from which a prediction can be performed. The security tool translates the sequential patterns into a Dynamic Bayesian Network prediction model. A temporal reasoning engine then feeds the model with the current event status and predicts what events are likely to happen in next time window, and with what probability.

Abstract: A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes adjustable focus IR optics. For example, the camera may include a focus mechanism coupled to the IR optics and configured to move the IR optics to various focus positions so as to focus the IR optics. The various focus positions may include a hyperfocal position in which a scene is in focus between a set distance and infinity, and a plurality of focus positions in which the scene is in focus between the set distance and a minimum focus distance. Depending on the configuration of the camera, the IR optics of the camera may define an F-number greater than 1.0, and an axis of the IR optics may be offset from an axis of the VL optics by a distance less than 1.7 inches.
