- Abstract: Mental health counseling remains a major challenge in modern society due to
cost, stigma, fear, and unavailability. We posit that generative artificial
intelligence (AI) models designed for mental health counseling could help
improve outcomes by lowering barriers to access. To this end, we have developed
a deep learning (DL) dialogue system called Serena. The system consists of a
core generative model and post-processing algorithms. The core generative model
is a 2.7 billion parameter Seq2Seq Transformer fine-tuned on thousands of
transcripts of person-centered-therapy (PCT) sessions. The series of
post-processing algorithms detects contradictions, improves coherency, and
removes repetitive answers. Serena is implemented and deployed on
\url{https://serena.chat}, which currently offers limited free services. While
the dialogue system is capable of responding in a qualitatively empathetic and
engaging manner, occasionally it displays hallucination and long-term
incoherence. Overall, we demonstrate that a deep learning mental health
dialogue system has the potential to provide a low-cost and effective
complement to traditional human counselors with less barriers to access.

We propose to build a dialogue system that converses with the patients, helps them create and accomplish specific goals, and can address their emotions with empathy.
We show that our system generates more empathetic, fluent, and coherent responses and outperforms the state-of-the-art in NLU tasks while requiring less annotation.
