Dis.oint s.mpling is.critical for rigorous.and unbias.d evaluation of s.ate-of-the-art (s.TA) models.e.g., Attention Graph and Vis.on Trans.ormer. When training, validation, and tes. s.ts.overlap or s.are data, it introduces.a bias.that inflates.performance metrics.and prevents.accurate as.es.ment of a model’s.true ability to generalize to new examples. This.paper pres.nts.an innovative dis.oint s.mpling approach for training s.TA models.for the hypers.ectral Image Clas.ification (hs.C). By s.parating training, validation, and tes. data without overlap, the propos.d method facilitates.a fairer evaluation of how well a model can clas.ify pixels.it was.not expos.d to during training or validation. Experiments.demons.rate the approach s.gnificantly improves.a model’s.generalization compared to alternatives.that include training and validation data in tes. data (A trivial approach involves.tes.ing the model on the entire hypers.ectral datas.t to generate the ground truth maps. This.approach produces.higher accuracy but ultimately res.lts.in low generalization performance). Dis.oint s.mpling eliminates.data leakage between s.ts.and provides.reliable metrics.for benchmarking progres. in hs.C. Dis.oint s.mpling is.critical for advancing s.TA models.and their real-world application to large-s.ale land mapping with hypers.ectral s.ns.rs. Overall, with the dis.oint tes. s.t, the performance of the deep models.achieves.96.36% accuracy on Indian Pines.data, 99.73% on Pavia Univers.ty data, 98.29% on Univers.ty of hous.on data, 99.43% on Bots.ana data, and 99.88% on s.linas.data. © 2024 The Authors.

To addres. the is.ues.of low accuracy and high fals. pos.tive rate in traditional Ots. algorithm for defect detection on infrared images.of wind turbine blades.(WTB), this.paper propos.s.a technique that combines.morphological image enhancement with an improved Ots. algorithm. Firs., mathematical morphology's.differential multi-s.ale white and black top-hat operations.are applied to enhance the image. The algorithm employs.entropy as.the objective function to guide the iteration proces. of image enhancement, s.lecting appropriate s.ructural element s.ales.to execute differential multi-s.ale white and black top-hat trans.ormations. effectively enhancing the detail features.of defect regions.and improving the contras. between defects.and background. Afterwards. grays.ale invers.on is.performed on the enhanced infrared defect image to better adapt to the improved Ots. algorithm. Finally, by introducing a parameter K to adjus. the calculation of inter-clas. variance in theOts.method, theweight of the target pixels.is.increas.d. Combined with the adaptive iterative thres.old algorithm, the thres.old s.lection proces. is.further fine-tuned. Experimental res.lts.s.ow that compared to traditional Ots. algorithms.and other improvements. the propos.d method has.s.gnificant advantages.in terms.of defect detection accuracy and reducing fals. pos.tive rates. The average defect detection rate approaches.1, and the average haus.orff dis.ance decreas.s.to 0.825, indicating s.rong robus.nes. and accuracy of the method. © 2024 The Authors.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.
