Our previous work on MuseNet explored synthesizing music based on large amounts of MIDI data. We chose to work on music because we want to continue to push the boundaries of generative models. We can then train a model to generate audio in this compressed space, and upsample back to the raw audio space. One way of addressing the long input problem is to use an autoencoder that compresses raw audio to a lower-dimensional space by discarding some of the perceptually irrelevant bits of information. Thus, to learn the high level semantics of music, a model would have to deal with extremely long-range dependencies. For comparison, GPT-2 had 1,000 timesteps and OpenAI Five took tens of thousands of timesteps per game. A typical 4-minute song at CD quality (44 kHz, 16-bit) has over 10 million timesteps. Generating music at the audio level is challenging since the sequences are very long. A different approach is to model music directly as raw audio. īut symbolic generators have limitations-they cannot capture human voices or many of the more subtle timbres, dynamics, and expressivity that are essential to music. This has led to impressive results like producing Bach chorals, polyphonic music with multiple instruments, as well as minute long musical pieces. A prominent approach is to generate music symbolically in the form of a piano roll, which specifies the timing, pitch, velocity, and instrument of each note to be played. The idea helped her raising nearly $1 billion from sophisticated investors that included Oracle co-founder Larry Ellison and media mogul Rupert Murdoch, who is owed $125 million under the restitution order.īut Theranos’ blood tests never came close to working the way Holmes had boasted with the support of Balwani, resulting in the company’s collapse and a tale that has been the subject of a book, “Bad Blood,” an HBO documentary, “The Inventor,” and a Hulu mini-series, ”The Dropout,” which won Amanda Seyfried an Emmy in the starring role.Automatic music generation dates back to more than half a century. When Holmes is finally incarcerated, it will bring down the curtain on a saga that cast a bright light on a dark chapter in Silicon Valley that brought her fame and fortune before her scandalous downfall.Īfter dropping out of Stanford University in 2003 to found Theranos while still a teenager, Holmes promised to revolutionize healthcare with a technology that she promised would be able to scan for hundreds of diseases and other potential problems with just a few drops of blood. Davila has recommended that Holmes be imprisoned in Bryan, Texas. But they noted she has to prepare to travel outside of California, where she has been living in the San Diego area while free on bail. In Wednesday’s filing, Holmes’ lawyers didn’t disclose the location of the prison that she has been assigned to serve her sentence. Balwani, 57, was convicted for 12 felony counts of fraud and conspiracy committed while he was Theranos’ chief operating officer and living with Holmes. The father of both children is William “Billy” Evans, whom she met after breaking up with her former romantic and business partner, Ramesh “Sunny,” Balwani, who began serving a nearly 13-year prison sentence last month in Southern California. Holmes, 39, became pregnant with William shortly before the start of her high-profile trial in September 2021 and became pregnant with Invicta shortly after she was convicted of crimes that could have resulted in a prison sentence of up to 20 years. Holmes had originally been ordered to begin her prison sentence on April 27, but won a reprieve with a last-minute legal maneuver that gave her more time with her children. Holmes’ lawyers asked Davila to approve the May 30 prison reporting time to her two weeks to sort out several issues, including child care for her 1-year-old son William and 3-month-old daughter Invicta. The punishment also includes a $452 million restitution bill that Davila ordered Holmes to pay in a separate ruling issued late Tuesday. It came after a federal appeals court late Tuesday rejected Holmes’ bid to remain out of prison while she attempts to overturn her January 2022 conviction on four felony counts of fraud and conspiracy. District Judge Edward Davila set Holmes’ revised prison-reporting date after her lawyers proposed it in a Wednesday filing. SAN FRANCISCO (AP) - Disgraced Theranos CEO Elizabeth Holmes will remain free through the Memorial Day weekend before surrendering to authorities on May 30 to begin her more than 11-year prison sentence for defrauding investors in a blood-testing scam.
