Deep Learning idea-a-thon:
How to solve a problem
by designing novel neural network architectures?
CNN
RNN
Fully
Connected
Merge
CNN is suitable architecture to extract
features out of any data that has
spatial relationships. For example, An
photo image spatial info..or info
spread across space
In general, a recurrent neural network could
be considered as the best neural network
model for extracting features out of
temporal data. A temporal data is basically
a data that varies over time such as ECG,
music, speech, sentences, words. LSTM is
a advanced RNN
To classify / predict
To combine the learnings of
two neural networks.
(to combine the power of 2
people’s brains)
Attention
To learn to focus on the
most important aspects to
achieve a particular task
Generative
Deep Learning
To model creative tasks as
to compose a music or
to come up a painting

Key ideas to remember
From architecture to code ? (just learn early glimpse of how code looks like.)
Just 1 page of code is enough for a complex problems such as video question answering

Key ideas to remember
If you didn’t understand the code*, just don’t worry.
• Why not to worry?
• Solving the video question answering problem was not possible until 2017.
• To solve this problem, it required dozens of experts in Google lab to dedicate 6 months of effort!
