I still use his linear algebra and Gaussian distribution notes as references in my classes. We will all miss him. I will never forget him. He was charming, open and approachable… you really wanted to be around him, bask in his glow, absorb his energy. In Sam spent a semester at MIT.

It has shocked me very much. He also realized that Principal Components Analysis PCA could be re-interpreted as the limit of a probabilistic model. The joys are second-to-none, but the pressures and the feeling that you might just lose to the ever-increasing demands are at times intense. I met Sam during his high school days at UTS. Code submission should be encouraged but not compulsory. The system can take any picture of the sky from any source, and instantly identify the location, orientation, and magnification of the image, as well as name each object star, galaxy, nebula it contains.

My last interaction with Sam, last week, was discussing a new research direction that interested him, optimizing theesis cost of acquiring feature information in the learning algorithm. One effective use of learned models is made by performing model inversion or state inference on incoming observation sequences to discover the underlying state or control parameter trajectories which could have produced them.

I know roweiis many of his friends will be glad to witness him in this professional capacity. My heart aches from this sorrowful goodbye.

He was fond of saying that Google’s search engine is one of the closest things we have to an intelligent computer. He was appointed to a Canadian Research Chair in statistical machine learning, and received a Sloan research followship in I wish I met you Sam.

Sam was supposed to outlive and outshine us all and we thewis supposed to stand behind him and cheer and now everything has gone so wrong. It has shocked me very much. Sam was an amazing individual. He also realized that Principal Components Analysis PCA could be re-interpreted as the limit of a probabilistic model.

I have fond memories of his enthusiasm and razor sharp intellect on display at the weekly seminars and tea time. But I saw few of his lectures from http: But thexis know that his many responsibilities were great, and it is well understood that basically all sane researchers have legions of inner doubts.

He stood out as a clear and thoughtful speaker with a gift for teaching as well as research. The reply that I owed him feels rowels, and an incompleteness is hanging.

Sam was a dear friend of our family and we are all so, so sad. Roweis, I had watched the videos of his teaching Machine Learning many times, and I admire him as a leading researcher in this field. Natalia Hernandez Gardiol says: This dissertation presents a series of experiments which investigate articulatory speech processing using real speech production data from a database containing simultaneous audio and mouth movement recordings.

My deepest condolences to his family. This was really shocking.

Despite his hectic schedule his door was always open to a wayward student seeking advice, academic or personal.

Sam Roweis, Associate Professor

Sam made several contributions to the then-nascent field of molecular and DNA computing. Thank you for writing this.

He proposed a variation of the well-established Hidden Markov Model HMM method for speech recognition, and he showed how a new form of Independent Component Analysis ICA could be used to separate multiple audio samm from a single microphone signal.


I also describe an inversion algorithm which estimates movements from an acoustic signal Finally, I demonstrate the use of articulatory movements, both true and recovered, in a simple speech recognition task, showing the possibility of doing true articulatory speech recognition in artificial systems.

I was lucky to have gotten to work with Sam in the past, and I was stuck not only by his thoughtfulness, but also with his patience and enthusiasm.

He was soo enthusiastic about what he was teaching, that his enthusiam was contagious, even through a PC screen. He realized that non-linear dynamical systems could be sqm using the Expectation-Maximization EM algorithm.

Take it easy now Sam. Many members of the research community became friends with Sam, because of his warm and friendly personality, his communicative smile, and his natural inclination to engagement and enthusiasm.
