Meanwhile, the evaluation and optimization of LLMs in software engineering tasks, such as code generation, have become a research focus. However, there is still a lack of systematic research on applying and evaluating LLMs in software engineering. Therefore, this paper comprehensively investigate and...

词嵌入(Token Embeddings):词汇表大小 V 乘以隐藏层维度 H,即 V \times H。self.embed = nn.Embedding(V, H) 位置嵌入(Position Embeddings):最大序列长度 L_{\text{seq}} 乘以隐藏层维度 H,即 L_{\text{seq}} \times H, 注意,在 BERT 的官方实现中该部分是可以训练的。 分段嵌入(Segment Embeddings...
We can think of self-attention as a mechanism that enhances the information content of an input embedding by including information about the input’s context. In other words, the self-attention mechanism enables the model to weigh the importance of different elements in an input sequence and dyna...
21 explained the influence affected on performance when applying MTL methods to 40 datasets, including GLUE and other benchmarks. Their experimental results showed that performance improved competitively when learning related tasks with high correlations or using more tasks. Therefore, it is significant...
But rather to uplift, to inspire, and astound So let us speak of wit and cleverness instead … Setting the bad rhyme wound/astound aside, perhaps the response can be fixed by adding the Grumio quote as an example of a rant and applying the change to the prompt. Let’s try that. ...
While applying deep learning techniques to text understanding will continue to enhance Facebook products and experiences, the reverse is also true. The unstructured data on Facebook presents a unique opportunity for text understanding systems to learn automatically on language as it is naturally used ...
This involves a preprocessing step that replaces each word in the training text with a word-concept pair, after which a regular embedding training is applied. While this method violates our intention to avoid the memory cost and data sparsity issue in training sense embeddings, we refer to the...
