  • Patent number: 11514309
    Abstract: Embodiments of the present invention provide a method and apparatus for accelerating distributed training of a deep neural network. The method comprises: based on parallel training, the training of deep neural network is designed as a distributed training mode. A deep neural network to be trained is divided into multiple sub-networks. A set of training samples is divided into multiple subsets of samples. The training of the deep neural network to be trained is performed with the multiple subsets of samples based on a distributed cluster architecture and a preset scheduling method. The multiple sub-networks are simultaneously trained so as to fulfill the distributed training of the deep neural network. The utilization of the distributed cluster architecture and the preset scheduling method may reduce, through data localization, the effect of network delay on the sub-networks under distributed training; adapt the training strategy in real time; and synchronize the sub-networks trained in parallel.

  • Publication number: 20220370371
    Abstract: Currently available glutaminase inhibitors are generally poorly soluble, metabolically unstable, and/or require high doses, which together reduce their efficacy and therapeutic index. These can be formulated into nanoparticles and delivered safely and effectively for treatment of pancreatic cancer and other glutamine addicted cancers. Studies demonstrate that nanoparticle delivery of BPTES, relative to use of BPTES alone, can be safely administered and provides dramatically improved tumor drug exposure, resulting in greater efficacy. GLS inhibitors can be administered in higher concentrations with sub-100 nm nanoparticles, since the nanoparticles package the drug into “soluble” colloidal nanoparticles, and the nanoparticles deliver higher drug exposure selectively to the tumors due to the enhanced permeability and retention (EPR) effect. These factors result in sustained drug levels above the IC50 within the tumors for days, providing significantly enhanced efficacy compared to unencapsulated drug.

  • Patent number: 11507766
    Abstract: A method for processing an encoded pattern, a storage medium, and an electronic device are disclosed in this application. An electronic device acquires a first encoded pattern to be recognized, the first encoded pattern being a pattern obtained after predefined information is encoded therein. The electronic device increases resolution of the first encoded pattern through a target model to obtain a second encoded pattern, the target model being obtained through training by using a predetermined third encoded pattern as an input and a predetermined fourth encoded pattern as an output, the third encoded pattern being obtained by decreasing resolution of the fourth encoded pattern, the third and the first encoded patterns being encoded in the same manner. Finally, the electronic device decodes the second encoded pattern using a code recognition module to obtain the predefined information. This application resolves the technical problem that an encoded pattern cannot be accurately recognized.
