Using patches with the same size as inputs to CNN can avoid the problems caused by arbitrary aspect ratios of scene images. The trained classifiers can mine discriminative patches to accurately identify some confusing scripts. The experimental results show the good performance of our approach on four public datasets.
To this end, we propose Hard Patches Mining (HPM), a new training paradigm for MVM.Specifically, given input visual signals, instead of generating a binary mask under pre-defined criteria, the model first acts as a teacher, identifying hard patches and subsequently producing challenging problems and then, as a student, predicts masked …

Meanwhile, during inter-domain teacher-student learning, CROTS fosters Hard Patches Mining strategy to mitigate the class imbalance phenomenon. To this end, the inter-domain teacher model helps exploit samples of long-tailed rare classes and increase their contribution to student learning, which regularizes the student model to avoid forgetting ...
Hard Patches Mining for Masked Image Modeling Haochen Wang, Kaiyou Song, Junsong Fan, Yuxi Wang, Jin Xie, Zhaoxiang Zhang; Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023, pp. 10375-10385 Abstract. Masked image modeling (MIM) has attracted much research attention due to its …
To this end, we propose Hard Patches Mining (HPM), a brand-new framework for MIM pre-training. We observe that the reconstruction loss can naturally be the metric of the difficulty of the pre-training task. Therefore, we introduce an auxiliary loss predictor, predicting patch-wise losses first and deciding where to mask next. ...

From 8 a.m. to 3:30 p.m. on Saturdays and Sundays, or 1 to 4:30 p.m. on Thursdays and Fridays, you can stop by Demarest Farms in Hillsdale to pick your own brightly colored pumpkin at their patch.
The major types of iron ore formations in India are banded iron formations from the Precambrian era and laterite ores derived from sub-aerial weathering. The key iron ore minerals are magnetite, hematite, siderite and limonite. India's major iron ore mining districts are located in Odisha, Jharkhand, Chhattisgarh, Karnataka, Goa and other states.
The predominant method for the synthesis of aromatic azo compounds is the azo coupling reaction, a S E Ar-type reaction between an aryl diazonium salt and an 'activated' (electron-rich) aromatic partner. 18 For BHQ-1 derivatives, commercially available Fast Corinth V (zinc chloride double salt) is used as the electrophilic partner …
The iron ore deposits of the Eastern, Central and Southern zone do not contain much overburden material except laterite and some low grade ferruginous shales and BHQ patches, whereas, in Western zone (Goa region) more than 30 MT of iron ore is produced during 200607 and another to times of the waste is excavated as overburden.
Masked image modeling (MIM) has attracted much research attention due to its promising potential for learning scalable visual representations. In typical approaches, models usually focus on predicting specific contents of masked patches, and their performances are highly related to pre-defined mask strategies. Intuitively, this …
Banded hematite quartzite (BHQ) and banded hematite jasper (BHJ) ores represent a promising potential iron ore resource in the near future.
The iron ore resources at KMIOD are being developed through opencast mining operations (maximum depth of 110 m) by Steel Authority of India Limited (SAIL), a public sector undertaking, Government of India since 1964. ...

According to National mineral policy projections, exploitation of the low grade iron ore horizons like BHJ, BHQ, and BIF etc. is necessary to achieve zero waste mining. BHJ assaying up to 40% Fe(T) has to be upgraded above 60% Fe(T) to use effectively It may also be noted that attaining liberation may be an extremely difficult job requiring ...
