چکیده
The development of mineral prospectivity mapping (MPM), which aims to outline and prioritize exploration targets, has been spurred by advances in data-driven machine learning algorithms. Supervised MPM is a typical few-shot task, suffering from scarcity labeled data, the over-fitting models an uncertainty predictions. main objective this contribution propose robust framework (FSL), combining data augmentation transfer enable generation with excellent predictive efficiency low uncertainty. systems approach was used conceptual system into mappable criteria. Synthetic minority over-sampling technique (SMOTE) employed augment balance dataset, allowing for model pre-training large synthetic training dataset source domain. knowledge derived pre-trained then transferred target domain fine-tuning, generated light assessments. proposed FSL applied tungsten southern Jiangxi Province. results indicated that SMOTE-ed balanced boosted classification accuracy process. yielded arch-shaped prediction point pattern favorable focusing potential targets high probability achieved performance (test AUC = 0.9172) lowest quantitative value compared benchmark algorithms random forest support vector machine. Four levels targeting zones, considering both uncertainty, were extracted resulting map. final high-potential low-risk only cover 4.27% area, but capture 41.53% known deposits, thus achieving superior performance. This study highlights capability control generate high-confidence

Few-shot Learning
Though deep neural networks have shown great success in the large data domain, they generally perform poorly on few-shot learning tasks, where a classifier has to quickly generalize after seeing very few examples from each class. The general belief is that gradient-based optimization in high capacity classifiers requires many iterative steps over many examples to perform well. Here, we propose ...
متن کاملOne-shot and few-shot learning of word embeddings
Standard deep learning systems require thousands or millions of examples to learn a concept, and cannot integrate new concepts easily. By contrast, humans have an incredible ability to do one-shot or few-shot learning. For instance, from just hearing a word used in a sentence, humans can infer a great deal about it, by leveraging what the syntax and semantics of the surrounding words tells us. ...
متن کاملDelineation of podiform-type chromite mineralization using geochemical mineralization prospectivity index and staged factor analysis in Balvard area (SE Iran)
The aim of this work was to delineate the prospects of podiform-type chromite by staged factor analysis and geochemical mineralization prospectivity index in Balvard area, SE Iran. The stream sediment data and fault density were used as the exploration features for prospectivity modeling in the studied area. In this regard, two continuous fuzzified evidence layers were generated and integrated ...
متن کاملFew-Shot Learning with Graph Neural Networks
We propose to study the problem of few-shot learning with the prism of inference on a partially observed graphical model, constructed from a collection of input images whose label can be either observed or not. By assimilating generic message-passing inference algorithms with their neural-network counterparts, we define a graph neural network architecture that generalizes several of the recentl...
متن کاملFew-shot Classification by Learning Disentangled Representations
Machine learning has improved state-of-the art performance in numerous domains, by using large amounts of data. In reality, labelled data is often not available for the task of interest. A fundamental problem of artificial intelligence is finding a representation that can generalize to never seen before classes. In this research, the power of generative models is combined with disentangled repr...
