Conventional n-gram language models are known for their limited ability to capture long-distance dependencies and their brittleness with respect to within-domain variations. In this paper, we propose a k-component recurrent neural network language model using curriculum learning (CLKRNNLM) to address within-domain variations. Based on a Dutch-language corpus, we investigate three methods of curriculum learning that exploit dedicated component models for specific sub-domains. Under an oracle situation in which context information is known during testing, we experimentally test three hypotheses. The first is that domain-dedicated models perform better than general models on their specific domains. The second is that curriculum learning can be used to train recurrent neural network language models (RNNLMs) from general patterns to specific patterns. The third is that curriculum learning, used as an implicit weighting method to adjust the relative contributions of general and specifi...
