    Avery Wang: Principal Research Scientist, Apple and Chief Scientist, Shazam

    Avery Wang: Principal Research Scientist, Apple and Chief Scientist, Shazam

    My guest today is Avery Wang – co-founder and Chief Scientist at music recognition app Shazam and now Principal Research Scientist at Apple.

    Almost ten years ago, I conducted my very first interview for my first book and it was with the Shazam founders. The story of Shazam is one of pure innovation, foresight, and friendship. In 1999,  Chris Barton dreamed of a seemingly impossible solution to ambient music recognition and created the team — including friend Dhiraj Mukherjee, classmate Philip Inghelbrecht and engineer Avery Wang — to make it a reality. Even after 20 years post launch, Shazam currently has over 200 MILLION monthly active users and was acquired by Apple in 2018.

    For regular listeners of this show, you will know that I spoke to fellow co-founder Dhiraj Mukherjee back In Series 1 but in today’s episode, Avery Wang talks me through the invention process – going all the way back to how as a child, he fell in love with science and maths and how his parents encouraged him to experiment, up to how he managed to invent the Shazam algorithm which every "expert" had said was impossible.

    I am so over the moon to share this interview with Avery – a first of its kind because Avery doesn’t do interviews. Everyone who knows him refers to him as a genius and it’s easy to see why. He holds over 150 US and international patents, has a Bachelor of Science degree and a Masters in Mathematics and a Masters and PhD in Electrical Engineering, all from Stanford. He also went to Germany as a Fulbright Scholar and studied Computational Neuroscience.

    I hope you enjoy this conversation as much as I did.

    Sensors, Collections & Phenomenology

    Sensors, Collections & Phenomenology

    Sensor technology is developing rapidly. New technologies and new applications are occurring frequently in the commercial sector and are being applied, matured or adapted for mission specific programs on the defense side too. 

    Talking us through how Leidos is involved in this arena is Cayley Rice, Enterprise Lead for Sensors, Collections & Phenomenology at Leidos. 

    With the influx of products and tools available commercially, and a growing trend of commercial sensors for common items like your doorbell, your smartphone or your thermostat, for example, how and where does Leidos fit into the picture? 

    What custom sensors isLeidos building and how are these being integrated into systems that can be rapidly deployed into some of the most demanding and mission critical kinds of environments?

    Cayley provides a fascinating insight into the challenges and requirements that we have for this technology, as well as the need to speed up the timeframe for adapting sensor systems to commercial speed.

    “We're basically adapting technology from the commercial world that got us smartphones, and using that same kind of process to advance micro-electronics for sensors and signal processing.”

    On today’s podcast:

    • Sensors, Collections & Phenomenology
    • The capabilities Leidos has in this arena
    • The opportunities with sensors for government agencies today
    • What distinguishes Leidos from the commercial space
    • The challenge of cycle time to new innovations

    Making Deep Learning Human with Prof. Gilbert Strang

    Making Deep Learning Human with Prof. Gilbert Strang

    Mathematics Professor Gilbert Strang is one of MIT’s most revered instructors; his courses, especially the perennially popular linear algebra course 18.06, have received millions of visits on OpenCourseWare, and his lecture videos have won him a devoted following on YouTube as well. (A sample YouTube comment on one of his lectures: “This is not lecture, this is art.”) A few years ago, Professor Strang began teaching a new course (18.065) focusing on the application of mathematical matrices to deep learning and AI. This new course is very unlike a typical undergraduate math course. For one thing, there’s no final exam—in fact, there are no exams at all! Instead, Professor Strang asks each student to spend the semester developing a project that applies the techniques they’re studying to some topic or problem they personally find interesting. In this episode, we hear from Professor Strang about his efforts to humanize math teaching, the value of thinking through problems in real time during lectures—even if it means getting stuck and having to backtrack!—and the importance of staying continually conscious of your students.

    Rand Steiger's Template for Improvising Trumpeter and Orchestra - La Jolla Symphony and Chorus

    Rand Steiger's Template for Improvising Trumpeter and Orchestra - La Jolla Symphony and Chorus
    As noted by the title, this piece centers on the talents of virtuoso trumpeter Peter Evans in a performance that is largely (though not entirely) improvised in performance. Evans’ tones are manipulated at times by the composer through digital signal processing, in what amounts to another interdependent and improvised performance; indeed, the watchwords for the entire enterprise are exploration and collaboration.

    Hum a Fingerprint, Extract a Melody - Dogac Basaran, CNRS - Voice Tech Podcast ep.009

    Hum a Fingerprint, Extract a Melody - Dogac Basaran, CNRS - Voice Tech Podcast ep.009

    This is the second part of my conversation with Dogac Basaran, a post-doctoral researcher at CNRS, the French national scientific research centre. If you missed the first part, you might want to go back and listen to the previous episode on Signal Processing Basics for Audio.

    Today, in part 2 of 2, we explore Dogac's research into audio fingerprinting, alignment, and melody extraction. By analysing the magnitude of frequency peaks and their relative spacing, Dogac shows us how it's possible to create audio fingerprints that can be used to detect and match audio recordings, even if they contain noise or are incomplete. These fingerprints have a variety of uses, including aligning multiple recordings of a single speaker/performance, and identifying a particular recording.

    We also discuss query by humming, the state-of-the-art technique that takes an audio fingerprint of a person humming a melody, and matches it to a database of music recordings. Dogac also explains why learning how to build neural networks has become an essential skill in this field.

    Signal Processing Basics for Audio - Dogac Basaran, CNRS - Voice Tech Podcast ep.008

    Signal Processing Basics for Audio - Dogac Basaran, CNRS - Voice Tech Podcast ep.008

    Dogac Basaran is a post-doctoral researcher at CNRS, the French national scientific research centre. Today, in part 1 of 2, Dogac gives us a crash course in signal processing, where we learn what signal processing is and discover some of its many applications. 

    Leveraging his teaching experience, Dogac uses simple language and real-world examples to explain the fundamental signal processing concepts that are used in voice technology today. He defines frequency, period, and stability, and describes how sound cards use sampling and the Nyquist theorem to convert analogue signals into digital.

    He then recommends some good educational resources and software packages, so you can learn more about signal processing and get started right away on your own programming projects.

    Correction [21/08/2018]: The term 'stationarity' was cited in the episode, but this should have been 'stability'.
