  ChatGPT, a widely-recognized large language model (LLM), has recently gained
substantial attention for its performance scaling, attributed to the billions
of web-sourced natural language sentences used for training. Its underlying
architecture, Transformer, has found applications across diverse fields,
including video, audio signals, and robotic movement. %The crucial question
this raises concerns the Transformer's generalization-in-learning (GIL)
capacity. However, this raises a crucial question about Transformer's
generalization in learning (GIL) capacity. Is ChatGPT's success chiefly due to
the vast dataset used for training, or is there more to the story? To
investigate this, we compared Transformer's GIL capabilities with those of a
traditional Recurrent Neural Network (RNN) in tasks involving attractor
dynamics learning. For performance evaluation, the Dynamic Time Warping (DTW)
method has been employed. Our simulation results suggest that under conditions
of limited data availability, Transformer's GIL abilities are markedly inferior
to those of RNN.
