Imbalance learning is an important branch of classification tasks in the field of machine learning, and has received increasing attention from researchers. Currently, most researches have focused on binary imbalanced problems, while there exist numerous unsolved multi-class imbalanced problems in real world. The diversity of data distributions and the poor performance of traditional multi-class classification algorithms pose significant challenges to classify multi-class imbalanced data. In this paper, we propose a resampling method named SMOTE-IF based on isolated forest to address the issue of imbalanced overlapping in multi-classification tasks. Firstly, in order to reduce the negative impact of having severely few minority classes, we first propose a SMOTE-based strategy to oversample them. Secondly, a variant of isolated forest is proposed, which can identify overlapped and noisy data in multi-class of boundaries. Numerous experiments on various real datasets have shown that the SMOTE-IF method can effectively handle imbalanced overlapping data. Compared with state-of-the-art resampling methods, SMOTE-IF has achieved significant improvements in different classification performance metrics.

New generations of spacecrafts are required to perform tasks with an increased level of autonomy. Space exploration, Earth Observation, space robotics, etc. are all growing fields in Space that require more sensors and more computational power to perform these missions. Furthermore, new sensors in the market produce better quality data at higher rates while new processors can increase substantially the computational power. Therefore, near-future spacecrafts will be equipped with large number of sensors that will produce data at rates that has not been seen before in space, while at the same time, dataprocessing power will be significantly increased. Use cases like guidance navigation and control applications, vision-based navigation has become increasingly important in a variety of space applications for enhancing autonomy and dependability. Future missions such as Active Debris Removal will rely on novel high-performance avionics to support image processing and Artificial Intelligence algorithms with large workloads. Similar requirements come from Earth Observation applications, where dataprocessing on-board can be critical in order to provide real-time reliable information to Earth. This new scenario of advanced Space applications and increase in data amount and processing power, has brought new challenges with it: low determinism, excessive power needs, data losses and large response latency. In this article, a novel approach to on-board artificial intelligence (AI) is presented that is based on state-of-the-art academic research of the well known technique of data pipeline. Algorithm pipelining has seen a resurgence in the high performance computing work due its low power use and high throughput capabilities. The approach presented here provides a very sophisticated threading model combination of pipeline and parallelization techniques applied to deep neural networks (DNN), making these type of AI applications much more efficient and reliable. This new approac
