WebFactorized embedding parameterization. In BERT, as well as subsequent modeling improve-ments such as XLNet (Yang et al., 2024) and RoBERTa (Liu et al., 2024), the WordPiece embedding size E is tied with the hidden layer size H, i.e., E H. This decision appears suboptimal for both modeling and practical reasons, as follows. WebFactorized embedding layer Parameterization. This is also known as the Reduction technique. In BERT the hidden layer embeddings and input layer embeddings are of the same size. In factorized layer parameterization the two embedding matrices are separated. This is because BERT uses a word piece tokenizer to generate tokens.
WebThe changes made to BERT model are Factorized embedding parameterization and Cross-layer parameter sharing which are two methods of parameter reduction. They also introduced a new loss function and replaced it with one of the loss functions being used in BERT (i.e. NSP). The last change is removing dropouts from the model. WebJun 28, 2024 · Using 0.46 times and 0.13 times parameters, our WideNet can still surpass ViT and ViT-MoE by 0.8% and 2.1%, respectively. On four natural language processing datasets, WideNet outperforms ALBERT by 1.8% on average and surpass BERT using factorized embedding parameterization by 0.8% with fewer parameters.
WebFeb 9, 2024 · Factorized embedding parameterization In BERT, the embeddings used (word piece embeddings) size was linked to the hidden layer sizes of the transformer blocks. Word piece embeddings learned from the one-hot encoding representations of a vocabulary of size 30,000 was used. These are projected directly to the hidden space of the hidden … WebJul 25, 2024 · On four natural language processing datasets, WideNet outperforms ALBERT by $1.8\%$ on average and surpass BERT using factorized embedding parameterization by $0.8\%$ with fewer parameters.

WebSep 28, 2024 · 1 — Factorized Embedding Parameterization. ALBERTS authors note that for BERT, XLNet and RoBERTa the WordPiece Embedding size (E) is tied directly to the H, Hidden Layer Size. However, ALBERT authors point out that WordPiece embeddings are designed to learn context independent representations.
WebJul 1, 2024 · Factorized embedding parameterization splits the vocabulary embedding matrix into two smaller matrices so that the vocabulary embedding is no longer connected to the size of the hidden layers in the model. Cross-layer parameter sharing means all parameters are shared across each layer, so the number of parameters does not … table rentals 11590WebOct 20, 2024 · The backbone of the ALBERT architecture is the same as BERT.
