Do you find yourself struggling to differentiate between BERT and GPT-3?
First: what exactly are transformers? In the simplest terms possible, they’re neural network architectures that can handle sequential data like text and speech. They were introduced in 2017 by Google researchers Vaswani et al., who published their groundbreaking paper “Attention is All You Need” (which sounds a bit like a self-help book title).
Now, Let’s get started with the diagram that will make your head spin:

Okay, so what are we looking at? Let’s break it down. First, there’s an input sequence (in this case, a sentence) being fed through the encoder. The encoder is essentially a series of layers that process each word in the input and pass them along to the next layer.
But wait, what’s with all those arrows pointing back and forth? That’s where attention comes into play. Attention allows the model to focus on specific parts of the input sequence based on their relevance to a particular output (in this case, generating a response). It’s like having a super-smart librarian who can instantly locate the book you need without wasting time flipping through every page in the library.
Next up is the decoder, which takes the encoded input and generates an output sequence based on it. The decoder also uses attention to help generate its response by focusing on specific parts of the input that are most relevant to what’s being generated. It’s like having a super-smart writer who can instantly come up with the perfect sentence without wasting time staring at a blank page.
Now, some popular transformer architectures and their applications:
1) BERT (Bidirectional Encoder Representations from Transformers): This is one of the most well known transformer models out there. It can be used for tasks like sentiment analysis, question answering, and text classification.
2) GPT-3 (Generative Pretrained Transformer 3): This model has been trained on a massive dataset of over 45 terabytes of text data. It’s capable of generating human-like responses to prompts and can be used for tasks like content creation, summarization, and translation.
3) RoBERTa (Robustly Optimized BERT Approach): This is an improved version of BERT that uses a different training strategy and has been shown to perform better on certain tasks. It’s particularly useful for tasks where accuracy is critical, like medical diagnosis or legal analysis.
Remember, AI isn’t perfect, but with the right tools and techniques, we can make some pretty amazing things happen!
