IPC: H04N21/4363
Filed: 2019-06-04
Abstract: The disclosed technology relates to adaptively encoding a video stream based on viewer engagement, content schedule and/or content characteristics. A system routes a video stream from a signal extractor to a first virtual encoder. The first virtual encoder is instantiated on a cloud platform and provides a first video output at a first bitrate. A second virtual encoder is instantiated on the cloud platform in response to a change in viewer count. The system routes the video stream from the signal extractor to the second virtual encoder. The second virtual encoder provides a second video output at a second bitrate. The second bitrate is different from the first bitrate.

Abstract: A first member of a blockchain obtains a blockchain asset transferred by a second member of the blockchain responsive to an asset transfer request of an off-chain asset, where the blockchain asset is issued by an anchor point at the blockchain and held at an account for the second member. When a first transfer-out operation for transferring the off-chain asset to a payee from an account opened at the first member fails, a second transfer-out operation to the payee is performed from a self-owned account of the first member. The first member writes a transaction reversal application for an asset transfer transaction corresponding to the asset transfer request into the blockchain in a blockchain account book at the blockchain. The first member performs an asset clearing with the second member for the off-chain asset corresponding to the second transfer-out operation.

Abstract: The invention is directed to a process and a system for removing sulfur dioxide from a feed gas stream. In the process the feed gas pre-scrubbed. Then SO2 is absorbed from the gas with an absorbing medium. The spent absorbing medium is regenerated. These process steps are interchanged with a caustic treatment in the pre-scrubbing zone in case of a very high SO2 content in the feed gas stream. The system comprises a pre-scrubbing unit, an absorption unit, and a regeneration unit. The system is characterized in that the pre-scrubber unit comprises an inlet for an aqueous solution comprising a strong base. These are a simple, cost-efficient and reliable process and facility for processing gas with a varying SO2 content.

S'il est déterminé que le mot a un vecteur de mot pré-entraîné, il s'ensuit que le vecteur de mot pré-entraîné du mot est obtenu. S'il est déterminé que le mot n'a pas de vecteur de mot pré-entraîné, il s'ensuit qu'un vecteur du mot est déterminé sur la base d'un vecteur de segment pré-entraîné. Le vecteur de mot et le vecteur de segment pré-entraîné sont entraînés sur la base d'un échantillon de texte et d'un modèle de vecteur de mot. Une entité associée au texte est prédite par l'entrée de vecteurs de mots de la pluralité de mots dans le modèle de prédiction d'entité.

IPC: G06K9/62
Filed: 2019-11-14
Abstract: A compatibility score generator implementing a neural network is trained for assessing compatibility of fashion items. Elements of a feature vector representing each fashion item and of a compatibility data structure indicating fashion items considered compatible are retrieved. The neural network is trained using training data corresponding to the fashion items and indicating compatibility between pairs of fashion items. The compatibility data structure is modified by removing indications that fashion items of a pair of fashion items are compatible. An encoding function is evaluated. Encoded representations are provided to a decoder that learns a likelihood that the indication had been removed when modified. The neural network and the decoder are optimized based on a loss function that reflects the decoder's ability to correctly determine whether the indication had been removed. The encoded representations generate a compatibility score for at least two fashion items of interest.
