C5W1 Recurrent Neural Networks Flashcards
1
Q
What are the tasks for RNN?
A
Speech recognition, music generation, sentiment analysis, DNA analysis, machine translation, video activity recognition, name entity recognition
2
Q
How RNN works?
A
RNN scans word by word, each previous scan passes activation to the next one
3
Q
Types of RNN?
A
Many to one
One to many
Many to many
One to one
4
Q
What is GRU?
A
Gate recurrent unit
Helps to remember long context
5
Q
What is LSTM?
A
Long term short memory
Same as GRU, but has 2 gates: update and forget gate
6
Q
What is bidirectional RNN?
A
RNN architecture which allows get information from the future.
The cons is that you need to have full sequence available, therefore you can use it for real time speech recognition
