Systematic Searches #11: Validating, Verifying and Revising Your Searches. A systematic search is an iterative one. We need to constantly evaluate, validate, or verify our search results, and revise and re-run the searches if necessary. This video introduces techniques in validating, verifying and revising your searches.

Edge intelligent data classification storage method

The invention relates to an edge intelligent data classification storage method, and belongs to the field of Internet of Things. The method comprises the following steps: firstly, designing a data preprocessing method, abstracting an intelligent entity state data sequence, and converting the intelligent entity state data sequence into a quantitative intelligent entity state sequence and a qualitative intelligent entity state sequence; then, performing feature extraction based on DSAE; then, outputting the extracted features to an SVM, and distinguishing of a transient intelligent entity and aslow-varying intelligent entity is achieved; and finally, storing the transient smart entity state data with relatively strong time-varying property at the edge, and storing the slow-varying smart entity state data with relatively weak time-varying property at the cloud center. According to the method, the state time-varying characteristics of the qualitative and quantitative state intelligent entities are mined, the intelligent entities are classified according to the time-varying degree, so that the state data of the intelligent entities are distinguished and cached according to the categorydifference, the search result accuracy of the Internet of Things search system is remarkably improved, and the search time delay for massive state time-varying intelligent entities is reduced.

Unmanned ship photoelectric intelligent reconnaissance method based on intelligent identification technology

The invention discloses an unmanned ship photoelectric intelligent reconnaissance method based on an intelligent identification technology, and relates to the field of intelligent identification and tracking. The method employs a search radar; and a photoelectric director, a comprehensive control system, a photoelectric display control end, an intelligent identification system and an inertial navigation system. The searching method comprises the steps of target searching, priority ranking, target finger movement, image recognition, target tracking and investigation circulation. The ship-borne radar, the photoelectric tracking system, the ship-borne inertial navigation system and the intelligent recognition system are integrated, and intelligent work of automatic searching, tracking, recognition, investigation evidence obtaining and auxiliary collision avoidance of the unmanned ship can be achieved. During use, after the search radar finds that a target enters a concerned area, the photoelectric tracking system turns to the angle of the target by receiving a target instruction, the automatic identification system identifies the target category, if the target is a suspicious target, automatic tracking reconnaissance evidence obtaining is performed, manual participation is not needed in the whole identification tracking process, and intelligent tracking reconnaissance and navigation collision avoidance are realized.

Click rate estimation model based on feature representation under attention mechanism

PendingCN113887694AEliminate the effects ofOvercome the problem that feature expression ability is limited by parameter scaleNeural architecturesNeural learning methodsAlgorithmOnline advertising
In order to complete click rate estimation according to object features of an object to be detected, the invention can be applied to the fields of enterprise-level recommendation systems, search systems, online advertisement systems and the like as a data fine arrangement link. The invention provides a click rate estimation model based on feature representation under an attention mechanism. The model comprises a feature embedding layer, and the feature embedding layer is used for carrying out the vectorization processing of continuous features and discrete features so as to form a stacked feature and explicit feature cross network, performing explicit feature combination and an implicit feature cross network on the stacking features through the attention cross network, performing implicit feature combination on the stacking features through the multi-layer perceptron, estimating a probability output layer, and estimating the click rate according to the received combined features, wherein the attention crossover network eliminates the dependence of an estimation model on artificial feature engineering, and meanwhile, due to the introduction of an attention mechanism, the importance of each combination feature on model estimation is distinguished, and the influence of useless and redundant features on the model is eliminated.
