The invention discloses an antagonistic cross-media search method based on limited text space. The method comprises the steps that a characteristic extraction network, a characteristic mapping networkand a modality classifier are designed, the limited text space is obtained by learning, image and text characteristics suitable for the cross-media search are extracted, and the mapping of the imagecharacteristic from image space to text space is achieved; the difference among characteristic distributions of different modality data is constantly reduced in the learning process by an antagonistictraining mechanism; and thereby the cross-media search is achieved. The antagonistic cross-media search method based on the limited text space has the advantages that behavioral expressions of peoplein cross-media search tasks can be better fitted; the image and text characteristics more suitable for the cross-media search tasks are obtained, and the defects of pre-training characteristics in anexpressive ability are made up; and the antagonistic learning mechanism is introduced, so that the search accuracy is further improved through the maximum minimum game between the modality classifierand the characteristic mapping network.

The method of redirection walking in virtual reality includes the steps: by means of a position sensor, acquiring the practical position coordinates of the user in the practical activity space; acquiring the current position information and the predicted position information of the user in a virtual scene; according to the pre-stored size information of the practical activity space, the practical position coordinates and the current position information and the predicted position information in the virtual scene activity space, and using the redirection walking algorithm to calculate the position coordinates of the next step of the user in the practical activity space; and according to the position coordinates of the next step, guiding the user to perform redirection walking in the practical activity space. The method of redirection walking in virtual reality can acquire the walking path information of the user in the practical activity space according to the virtual scene, and can guide the user to walk freely in the virtual world without exceeding the boundary of the real world, thus enlarging the activity space of the virtual world, and realizing the mapping from the limited practical space to the virtual infinite space.

The invention provides a large power grid overall situation on-line integrated quantitative evaluation method based on a response. The method comprises a first step of acquiring power grid topology structural information from an SCADA system and an EMS system and establishing a corresponding relation between the power grid topology structural information and a WAMS system power grid component, a second step of acquiring present power grid operation method trend data from the SCADA system or the EMS system or a WAMS system or acquiring various preconceived trends or transient state fault time domain data from a DSA system, and a third step of dividing responding data into two operation scenes including a steady state (or a quasi-stable state) and a transient state (or a dynamic state) in a macroscopic mode, wherein static state stabilization situation assessment is carried out on a power grid through an on-line node-facing method, and transient state stabilization situation assessment is carried out on the power grid through an on-line unit-facing method. Static state and transient state comprehensive assessment indicators are constructed based on component class thermostabilization, electric parameter acceptable range and system class stabilization, the comprehensiveness and reasonability of the overall situation assessment indicators are improved, and the efficiency of overall situation integrated assessment is improved through the method that tasks are carried out at the same time.
