Microsoft has introduced a new language modeling approach for text-to-speech synthesis (TTS) called VALL-E. The approach uses discrete codes derived from an off-the-shelf neural audio codec model, and is trained using 60K hours of English speech, which is hundreds of times larger than existing systems, and can be used to synthesize high-quality personalized speech with only a 3-second enrolled recording of an unseen speaker as an acoustic prompt (project page, paper).
In a recent paper from Dec 26, 2022, Google demonstrates that its large language model Med-PaLM, based on 540 billion parameters with a special instruction prompt tuning for the medical domain, reaches almost clinician’s performance on new medical benchmarks MultiMedQA (benchmark combining six existing open question answering datasets spanning professional medical exams, research, and consumer queries) and HealthSearchQA (a new free-response dataset of medical questions searched online). The evaluation of the answers considering factuality, precision, possible harm, and bias was done by human experts.
In the United States, most jurisdictions require applicants to pass the Bar Exam in order to practice law. This exam typically requires several years of education and preparation (seven years of post-secondary education, including three years at an accredited law school).
In a publication from Dec 29, 2022, the authors evaluated the performance of GPT-3.5 on the multiple choice part of the exam. While GPT is not yet passing that part of the exam, it significantly exceeded the baseline random chance rate
of 25% and reached the average human passing rate for the categories Evidence and Torts.
On average, GPT is performing about 17% worse than human test-takers across all categories.
Similar to this publication is the report that ChatGPT was able to pass the Wharton Master of Business Applications (MBA) exam.
