WebInformation-theoretic quantities reveal dependencies among variables in the structure of joint, marginal, and conditional entropies while leaving certain fundamentally different systems indistinguishable. Furthermore, there is no consensus on the correct higher-order generalisation of mutual information (MI).

Webend lattice-free maximum mutual information (LF-MMI) has been proposed [11]. These methods typically aim to train a neural network-based acoustic model in one stage … WebThe model is trained with lattice-free maximum mutual infor-mation (LF-MMI) [17]. The model uses 40-dimensional MFCC features together with i-vectors for speaker-adaptation [20, 21]. The MFCC features are extracted from recordings down-sampled to 8kHz and the i-vector extractor is trained on data pooled from all languages. the powers below
