Forests and forest ecosystems are vital to our social, economic, and environmental well-being. However, climate change and climate-driven disturbances (CDDs) are undermining the health and resilience of forests worldwide and pose significant uncertainty to sustainable forest management. Climate-smart forestry (CSF) remains a grand challenge in practice due to our limited knowledge of how forests respond to climate change and our abilities to collect related information to empower decision making. Rapid advances in artificial intelligence (AI) can offer a timely opportunity to address the challenges in CSF. We argue that the AI-enabled, next-generation CSF can be achievable through synergistically coordinated and transdisciplinary efforts that develop and advance foundational and use-inspired AI technologies that can lead to building next-generation forest decision support systems.

Learning from high-dimensional imbalanced data is a challenging research problem in machine learning, due to the curse of dimensionality caused by high dimension and the learning bias resulted from class imbalance. The existing works generally apply dimension reduction methods to reduce the dimensionality of features first, and then deal with the class imbalance problem by traditional imbalanced learning technologies. However, dimensionality reduction may cause the loss of useful information and cannot effectively address the problem of hubness which is an important aspect of the curse of dimensionality. In this paper, we present a hubness-aware cluster-based ensemble algorithm, HUSBoost, for learning high- dimensional imbalanced data. For hubs induced by high dimensionality, HUSBoost introduces discount factors to slow down the excessive growth of their weights, so as to alleviate the negative impacts of "bad" hubs on the classification decisions of component classifiers. To address the class imbalance problem, HUSBoost utilizes a cluster-based majority undersampling method to correct imbalanced class distribution. Specifically, k- hubs clustering technology is used to divide the majority samples into multiple clusters, and then the representative majority samples are selected from each cluster so as to form the balanced class distribution. Experimental results based on sixteen high-dimensional imbalanced data sets show the effectiveness of HUSBoost.
