Lyrics

[Verse 1]
When data flows in temporal streams
Sequential patterns chase your dreams
Vanilla RNNs start the fight
But gradients vanish out of sight
Each timestamp feeds the hidden state
But long-term memory meets its fate

[Chorus]
Recurrent networks learn through time
LSTM gates keep memories in line
GRU simplifies the gated flow
Attention shows us what to know
Sequential data finds its way
Through architectures built to stay

[Verse 2]
LSTM brings three gates to play
Forget gate throws old thoughts away
Input gate decides what's new
Output gate controls the view
Cell state carries information far
Long dependencies are now the star

[Chorus]
Recurrent networks learn through time
LSTM gates keep memories in line
GRU simplifies the gated flow
Attention shows us what to know
Sequential data finds its way
Through architectures built to stay

[Bridge]
Sequence to sequence translation
Encoder builds representation
Decoder generates each token
Attention mechanism keeps us woken
Bahdanau looks at every step
Luong keeps alignments prepped

[Verse 3]
GRU combines the forget and input
Reset and update gates throughout
State-space models like Mamba rise
Structured states before your eyes
Choose RNNs for sequential flow
Transformers when parallel you go

[Chorus]
Recurrent networks learn through time
LSTM gates keep memories in line
GRU simplifies the gated flow
Attention shows us what to know
Sequential data finds its way
Through architectures built to stay

[Outro]
Time series forecast in your lab
Financial data you can grab
Sensor readings through the day
LSTM models show the way
Memory gates and attention bright
Sequence models done just right
