New course will show journalists how machine learning can improve their reporting; Register now
Have you ever felt overwhelmed by the sheer number of images or documents, or hours of video footage you needed to sort through for a report? Training a machine to do the work for you may be the answer. Learn how artificial intelligence can improve your reporting with the new course from the Knight Center for Journalism in the Americas and instructor John Keefe, "Hands-on Machine Learning Solutions for Journalists." The four-week Big Online Course (BOC) runs from Nov. 18 to Dec. 15, 2019 and costs $95, which includes a certificate for those who successfully complete the course requirements. "At the end of this class, students will have a much better understanding of machine learning. They will actually be able to sort documents, especially images, based on the criteria they set up," said Keefe, who uses these techniques in his work as investigations editor at Quartz.
Introduction To Machine Learning And ML.NET
Artificial Intelligence has been a very popular area among computer scientists, researchers, and developers for many years. It is the capability to act intelligently and autonomously by machines in generic to more specific scenarios. We have come a long way in this field but there is still a long way to go to achieve a point where machines can think or act intelligently in a similar way to the human mind. For a few years now, we have been listening to the buzz word "Machine Learning". In this article, I am trying to give a high-level overview of machine learning, its applications and will introduce a platform called ML.Net provided by Microsoft to implement machine learning in .Net applications.
Facebook alters video to make people invisible to facial recognition
Facebook AI Research says it's created a machine learning system for de-identification of individuals in video. Startups like D-ID and a number of previous works have made de-identification technology for still images, but this is the first one that works on video. In initial tests, the method was able to thwart state-of-the-art facial recognition systems. The AI for automatic video modification doesn't need to be retrained to be applied to each video. It maps a slightly distorted version on a person's face in order to make it difficult for facial recognition technology to identify a person.
Penn Jillette's Surprising Success as a Computer Columnist
Penn Jillette, as a magazine columnist, strikes an interesting pose. Clearly, it was never a top line item on his resume, and it took place when being a prominent tech journalist tended to have a smaller profile than it does today. But he still did well enough in the role that, for a time, he became one of the best-known editorial voices on technology in the country, one that only occasionally mentioned his day job. Now, tech writing of this era doesn't have the pedigree of, say, good music journalism in the 1970s. Certainly, there were good tech writers during this time, particularly free-wheeling voices like fellow moonlighter Jerry Pournelle of Byte, hard-nosed insiders like journeyman scribe John C. Dvorak and the long-anonymous Robert X. Cringely, and well-considered newspaper voices of reason like syndicated columnist Kim Komando and the Wall Street Journal's Walt Mossberg.
A holistic approach to polyphonic music transcription with neural networks
Román, Miguel A., Pertusa, Antonio, Calvo-Zaragoza, Jorge
We present a framework based on neural networks to extract music scores directly from polyphonic audio in an end-to-end fashion. Most previous Automatic Music Transcription (AMT) methods seek a piano-roll representation of the pitches, that can be further transformed into a score by incorporating tempo estimation, beat tracking, key estimation or rhythm quantization. Unlike these methods, our approach generates music notation directly from the input audio in a single stage. For this, we use a Convolutional Recurrent Neural Network (CRNN) with Connectionist Temporal Classification (CTC) loss function which does not require annotated alignments of audio frames with the score rhythmic information. We trained our model using as input Haydn, Mozart, and Beethoven string quartets and Bach chorales synthesized with different tempos and expressive performances. The output is a textual representation of four-voice music scores based on **kern format. Although the proposed approach is evaluated in a simplified scenario, results show that this model can learn to transcribe scores directly from audio signals, opening a promising avenue towards complete AMT.
