hw2_image_classification icon hw2_image_classification

利用TensorFlow(TF),本作业实现了一个基于full convolution stack、inception v2 module等模块的图片分类网络,纵向共包含10层包含参数的层,采用自己搭建的卷积层。对于dset1与dset2采用同样的网络结构,分别进行训练。最终在dset1验证集(约含900张图,下同)上的Top1分类准确率约为0.52,在dset2验证集上的Top1准确率约为0.63。在K80显卡的单核上,该模型的训练速度约为205张图每秒,最终所得模型的checkpoint约为45MB。

hw3_language_model icon hw3_language_model

利用 PyTorch,本作业实现了一个基于word embedding和GRU的语言模型(Language Model,以下简称LM)。其包括一个encoder层、一个GRU层和一个decoder层,embedding维度与GRU的hidden state维度均为1500,采用了自己搭建的带有Layer Normalization(LN)的GRU模块,运用了dropout、学习初始状态、锁定encoder与decoder参数、梯度裁剪等技巧来提升模型性能,最终在测试集上模型的perplexity (PP)值为89.52,所得模型大小约为108M。
