Written Memories: Understanding Deriving and Extending the LSTM

When I was first introduced to Long Short-Term Memory networks (LSTMs), it was hard to look past their complexity. I didn’t understand why they were designed they way they were designed, just that they worked. It turns out that LSTMs can be understood, and that, despite their superficial complexity, LSTMs are actually based on a couple incredibly simple, even beautiful, insights into neural networks. This post is what I wish I had when first learning about recurrent neural networks (RNNs).
In this post, we do a few things:
We’ll define and describe RNNs generally, focusing on the limitations of vanilla RNNs that led to the development of the LSTM.
We’ll describe the intuitions behind the LSTM architecture, which will enable us to build up to and derive the LSTM. Along the way we will derive the GRU. We’ll also derive a pseudo LSTM, which we’ll see is better in principle and
