由于DNN模型可以看成一种层级迭代的结构,这种结构的曲率矩阵可以由FIM的方法去逼近,在这方面比较成功的例子是K-FAC方法,在这个方法中有两个假设: weight-gradients in different layers are assumed to be uncorrelated the input and output-gradient in each layer are
Batch Normalization and Layer Normalization are two widely used normalization techniques in neural networks. Batch Normalization normalizes the data based on the statistics of a mini-batch, whereas Layer Normalization normalizes the data based on the layer's input dimensions.Batch Normalizatio...
This makes it difficult to process using standard NLP techniques as these are typically trained on standard text. Text normalization is often used as a preprocessing step to overcome this problem. In this work, we take a machine translation perspective on text normalization and investigate both ...
4次BN只对一个样本进行,前6次BN和后4次BN失去了可比性。 另一方面,BN是在某个位置的维度进行标准化,这要求每个位置的特征表征的含义是固定的,而NLP中同一个词可以在句子中的任意位置出现,导致每个位置的特征表征含义不固定,从而BN难以产生效果。NLP领域常用的标准化操作为layer normalization,可以解决BN在该领域...
Preprocessing: Text data from customer reviews is cleaned and processed using text normalization techniques (stemming and lemmatization). Analysis: Sentiment is assessed using TextBlob to classify reviews into categories like positive, negative, or neutral. Recommendation Engine TF-IDF Vectorizer: Converts...
We believe that these errors may be solved with advanced language modeling techniques and mark these models as future work. 5.2. Qualitative analysis The primary goal of applying bidirectional RNNs to medical concept normalization is to capture “semantic representation” of a text based on not ...
by computing the normalization statistics separately at each time step. Layer normalization is very effective at stabilizing the hidden state dynamics in recurrent networks. Empirically, we show that layer normalization can substantially reduce the training time compared with previously published techniques....

lingual biomedical concept normalization problem. We show that the annotation quality can be improved significantly compared to the conventional string matching tool. For the future work, we aim to apply such techniques onto other types of annotations (e.g., biomedical name entities) or in other ...
Social media data is rich and diverse, but the evolving and varied language used in these contexts makes manual labeling labor-intensive and expensive. To tackle these issues, we propose a framework that integrates semi-supervised learning with weak supervision techniques. This approach enhances the ...
