论文摘要
最近引入了多任务学习和归纳转移学习的多层感知器中的任务嵌入。在许多情况下,这种方法可以改善预测错误并减少所需的培训数据。但是,它不会在一天之内(即昼夜周期)内的季节性影响。因此,我们将这个想法扩展到了时间卷积网络,以考虑这些季节性。我们建议通过卷积转换嵌入空间,其中包含任务之间的潜在相似性,并将这些结果提供给网络的残留块。与多层感知器方法相比,拟议的架构可显着提高25%的多任务学习对欧洲范围和Germansolarfarm数据集的功率预测。基于相同的数据,我们为风数据集取得了10%的改善,在大多数情况下,对于太阳能数据集而言,我们在没有灾难性遗忘的情况下实现了电感传输学习的20%以上。最后,我们是第一个提出可再生能力预测的零射击学习,即使没有培训数据,也可以提供预测。
Task embeddings in multi-layer perceptrons for multi-task learning and inductive transfer learning in renewable power forecasts have recently been introduced. In many cases, this approach improves the forecast error and reduces the required training data. However, it does not take the seasonal influences in power forecasts within a day into account, i.e., the diurnal cycle. Therefore, we extended this idea to temporal convolutional networks to consider those seasonalities. We propose transforming the embedding space, which contains the latent similarities between tasks, through convolution and providing these results to the network's residual block. The proposed architecture significantly improves up to 25 percent for multi-task learning for power forecasts on the EuropeWindFarm and GermanSolarFarm dataset compared to the multi-layer perceptron approach. Based on the same data, we achieve a ten percent improvement for the wind datasets and more than 20 percent in most cases for the solar dataset for inductive transfer learning without catastrophic forgetting. Finally, we are the first proposing zero-shot learning for renewable power forecasts to provide predictions even if no training data is available.
