618 results about "Sustainability" patented technology

Sustainability is the ability to exist constantly. In the 21st century, it refers generally to the capacity for the biosphere and human civilization to coexist. It is also defined as the process of people maintaining change in a homeostasis balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations. For many in the field, sustainability is defined through the following interconnected domains or pillars: environment, economic and social, which according to Fritjof_Capra is based on the principles of Systems Thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political. According to the Our Common Future, Sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs.” Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (i.e., development is inherently unsustainable).

Intrusion detection method and intrusion detection system based on sustainable ensemble learning

The invention, which belongs to the technical field of network intrusion detection, discloses an intrusion detection method and intrusion detection system based on sustainable ensemble learning. A multi-class regression model is constructed by using a class probability output and a classification confidence product of an individual learner as training data, so that the decision-making process of the ensemble learning has high adaptability to the attack type to improve the detection accuracy. At the model updating stage, parameters and decision results of historical models are added into the training process of a new model, thereby completing incremental learning of the model. According to the invention, on the basis of the ensemble learning fusion plan of the multi-regression model, the decision-making weights of the individual learner during the detection processes for different attack types are allocated in a fine granularity manner; and the parameters and results of the historical models are used for training the new model, so that the stability of the model is improved and the sustainability of the learning process is ensured.

Identity verification system based on face recognition

The invention discloses a network device based on a customer identity verification system, which aims to solve the problem that the cases resulting from name borrow and false name happen occasionally due to the shortcomings existing in the process of manually verifying the customer identity in the current financial industry. A customer terminal consists of a group of self-service information acquisition and real-time comparison terminals which perform real-time comparison on the information acquired by a camera and a second-generation identity card reader and directly transmit the acquired information and the comparison result to a background server or forward through a middleground server; and a third-party server reads the required information and comparison result directly from the background server database through a communication interface or through the middleground server. Through the invention, the identification accuracy of the customer identity is high, and the cases resulting from name borrow and false name in the banking business are greatly reduced. In combination with the characteristics of the bank, the information can be acquired in a self-service manner and automatically identified and compared to avoid human risk in the banking business, thereby laying a firm foundation for the sustainable development of the bank.
