Comparitive Study of GRU and LSTM Cells Based Video Captioning Models
(Institute of Electrical and Electronics Engineers Inc., 2021) Maru, H.; Chandana, T.S.S.; Naik, D.
Video Captioning task involves generating descriptive text for the events and objects in the videos. It mainly involves taking a video, which is nothing but a sequence of frames, as data from the user and giving a single or multiple sentences (sequence of words) to the user. A lot of research has been done in the area of video captioning. Most of this work is based on using Long Short Term Memory (LSTM) units for avoiding the vanishing gradients problem. In this work, we purpose to implement a video captioning model using Gated Recurrent Units(GRU's), attention mechanism and word embeddings and compare the functionalities and results with traditional models that use LSTM's or Recurrent Neural Networks(RNN's). We train and test our model on the standard MSVD (Microsoft Research Video Description Corpus) dataset. We use a wide range of performance metrics like BLEU score, METEOR score, ROUGE-1, ROUGE-2 and ROUGE-L to evaluate the performance. Â© 2021 IEEE.
