Wafer is the crucial raw material of semiconductor devices. In wafer production, impurities cannot be removed entirely, which will cause various wafer map defects. Quickly and precisely classifying wafer map defects can help engineers track failures in the semiconductor manufacturing process. However, different wafer map defect patterns occur randomly and irregularly, and labeling work is labor-intensive and time-consuming. Therefore, the wafer map dataset is usually imbalanced and consists of many unlabeled data. In this paper, we utilize unlabeled data by using semi-supervised learning methods and alleviate the imbalance problem by optimizing the loss function to increase the accuracy of wafer map classification. The performance of the proposed method is illustrated with the WM-811K dataset which consists of real-world wafer maps.

The disaster relief operations during floods require time critical information of the flooded area to save lives. Finding critical regions of the disaster struck area in a limited time frame is crucial for effective relief planning. In this paper, we propose a multi-UAV based system with directed explorations of flooded area to gather time-critical ground information using deep reinforcement learning based controls. We learn an exploration policy for the multi-UAV system with limited battery for autonomous coverage of the flooded region. Further, we integrate D8 flow algorithm that approximates the water flow direction based on image pixel information of a sub-region in the UAVs' exploration strategy. The results show that our proposed method for multi-UAV exploration of flooded area outperforms other methods from the literature. Moreover, the learnt multi-UAV exploration policy is able to generalize to unseen flooded regions without any retraining.
