有点像图像分析中的Image Classification任务。 难点/关键点 代码语言:javascript 代码运行次数:0 运行 AI代码解释 强有力的特征: 即如何在视频中提取出能更好的描述视频判断的特征。 特征越强,模型的效果通常较好。特征的编码(encode)/融合(fusion): 这一部分包括两个方面, 第一个方面是非时序的,在使用多种特征...
In this post we are going to construct first a Gated Recurrent Unit (GRU) neural network usingPython. Then we will construct a Long Short Term Memory (LSTM) neural network and try to make predictions. We will use GBPUSD daily data. The last observation is the GBPUSD Flash Crash in which ...

https://stackoverflow.com/questions/38059247/using-tensorflows-connectionist-temporal-classification-ctc-implementation 根据tensorflow 1.0.1的版本做了微调,使用了Adam作为optimizer。 需要注意的是ctc_beam_search_decoder是非常耗时的. 和greedy_decoder的区别是,greedy_decoder根据当前序列预测下一个字符,并且取概率...
《Attention-based LSTM for Aspect-level Sentiment Classification》 # polarity 和 aspect 都是有的,但是在一句话里,不同的target里面可能有不同的情感极性。 # 所以单纯的LSTM模型是不行的。要加上attention机制。 1. 不同的aspects被考虑到 2. concatenate aspect into hidden representations, 将aspect vect.....
