Beyond Transformers

Beyond Transformers

In consideration of the future breakthroughs beyond Transformers, let's examine their limitations.

• Quadratic cost complexity in the input sequence.
• Static weights that don't change during inference. Compare this to “incremental learning.”
• Mathematical reasoning limitations.
• Attribution and transparency issues.
• Lack of general common sense
• No real “world model” (superficial understanding)

Some other areas arise in terms of the other architectures which have advantages over Transformers in some types of computations.

• Hybrid RNN-Transformers. The sequence-processing methods of RNNs have some advantages, although Transformers are fairly good at sequences, too.
• Hybrid CNN-Transformers. Combine the CNN's innate image processing abilities with Transformers.

But here's my prediction for what comes after Transformers: more Transformers, by which I mean ensemble architectures that combine multiple models.
