Cognition is essential for many complex real-world tasks; it subsumes critical capabilities regarding knowledge, memory, and reasoning. We present several approaches that address multiple challenges of machine cognition—modeling long-range memory, unifying autoregressive and auto-encoding methods, multi-hop reasoning, and semi-supervised learning on complex structured data. Empirically, Transformer-XL became the first attention model to fully surpass LSTMs on language modeling; XLNet outperformed BERT on 20 tasks under fair comparison and achieved state-of-the-art results on 18 tasks.
