AND SO THE W THEN YOU HAVE UH PREDICTOR IS FITTING ACTUALLY THIS COMPRESS SIGNAL BUT YOU KNOW HOW MUCH C IT WAS COMPRESSED SO YOU CAN ALWAYS EXPAND IT BACK SO THAT YOU GET THE C THAT YOU GET A FIT TO THE TO THE ORIGINAL THING EXCEPT THAT IF IT IS DIFFERENT BECAUSE UH IT HA TH BASICALLY THIS OPAL MODELING HAS A DIFFERENT PROPERTIES AND UH IT'S YEAH THIS IS AN UH SORT OF OLD TECHNIQUE WHICH UH IT MM-HMM AND IT WAS MY THESIS EVEN P. H. D. THESIS ACTUALLY A SMALL SORRY YEAH IT WAS S. T. L. P. WAS CALLED SPECTRAL TRANSFORM LINEAR PREDICTION IT WAS MY FIRST ICASSP PAPER EVER IT WAS UH IT NINETEEN EIGHTY THREE BOSTON YOU GUYS WERE STILL IN KINDERGARTEN RIGHT OH THIS IS TERRIBLE SO BUT NO NOBODY NOBODY WAS USING IT FOR ANYTHING EXCEPT IT WAS CUTE BUT THAT WAS ABOUT IT AND UH AND BUT NOW IT SEEMS LIKE THAT IS SINCE SINCE WHAT WE ARE DOING HERE WE ARE NORMAL L. P. C. IS FITTING UH PEAKS RIGHT BUT WHEN YOU ARE MODELING HILBERT ENVELOPE YOU DON'T NECESSARILY WANT TO FIT ONLY PEAKS YOU SOMETIMES WANT TO GET A BASICALLY GOOD ESTIMATE OF THE OF THE ENVELOPE SO THAT HELPS YOU BECAUSE IN THIS UH THI THI THIS SPECTRAL TRANSFORM ALLOWS YOU TO TO FIND THE RIGHT BALANCE BETWEEN HOW WELL IT FITS PEAKS HOW HOW WELL IT FITS DIPS AND UH AND YEAH AND SORT OF THE SO THIS IS G SO I THINK THAT BASICALLY I DON'T KNOW WHAT ELSE I MEAN YOU SHOULD BE ASKING QUESTIONS RIGHT SO UH ONE THING I WANTED TO KNOW IS ANY UM A GOOD LITERATURE ON THESE LINES UH WHERE YOU STARTED WITH YEAH YEAH YEAH THEY ARE ABOUT THREE PAPERS THERE WAS UH THE S S S SAPA OR HOW IT'S CALLED THE CONFERE THEN THEN INTERSPEECH PAPER I AND ONE WAS IN THE A. S. R. U. IT WAS FROM VIRGIN ISLANDS SAPA WAS A S I I TELL YOU WHAT IT STANDS FOR STATISTIC AND AD AND SOMETHING AD AND UH PERCEPTUAL APPROACHES I WAS ON F I WAS ON A F W S ORGANISING COMMITTEE I SHOULD KNOW BUT STATISTIC AND UH AND SOMETHING APPROACHES UH PE PERCEPTUA AND STATISTICS AND PERCEPTUAL A APPROACHES THAT WAS UH AT LEAST TWO REPORTS FROM MARIUS SEEM TO ME YEAH THEY ARE MORE LESS THEY ARE SAME LIKE I THINK THERE WA UH THE READING LES ATLAS'S PAPERS ARE VERY GOOD BECAUSE LES ATLAS IS DOING A LOT OF WORK ON CODING IN THIS DOMAIN HE DOESN'T USE OPAL MODEL BUT HE USES D. C. T. AND THEN HE P UH SO THE SO SO AND IT AND LES IS EXCELLENT GUY HE'S VERY GOOD MATHEMAT MM H VERY GOOD THEORETICIAN BASICALLY HE'S A HE'S AT STANFORD THE GUY AND UH REALLY HE LIKES TO WRITE THINGS WELL SO HE'S VERY RIGOROUS UH AS OPPOSED TO S TO ME FOR INSTANCE SO IF YOU READ THAT THEN IT THEN YOU KNOW THAT THERE ARE NO ERRORS AND YEAH UH BUT UM SO WHATEVER YOU G WHATEVER YOU GET HANDS ON FROM LES ATLAS UH FOR OVER PAST FIVE YEARS UH REGARDI THIS TWO YEARS AGO LAST YEAR ON ONE OF THE ICASSPS HE HAD LIKE FIVE PAPERS RIGHT OR VARIOUS ASPECTS OF THIS BECAUSE UH HE'S EAGER TO BUT IT WAS REGARDED TO SPEECH RECOGNITION SOMEHOW Y YEAH YEAH IT WAS NOT SOMETHING LIKE SPEECH CODING OR THAT D. C. T. TRANSFORMS N NOTHING LIKE THAT I DON'T SO ALSO I CAN UM BEFORE MARIUS LEFT HE HE HAS HE HAD ACTUALLY LEFT HIMSELF BUT ALL THE FILES ARE HERE YOU KNOW SO ALL THE M MATLAB IMPLEMENTATIONS OF THESE ARE HERE AND THERE IS ALSO ONE BIG TABLE THAT HE USED HE USED TO YEAH HE WAS ALSO PLAYING WITH ALL THESE COMPRESSION FACTORS AND LENGTHS OF THE OF OF THAT AND THERE IS A BIG TABLE IN IN EXCEL WHICH YOU CAN LOOK AT YEAH YEAH YEAH THIS WA UH YEAH BECAUSE IT IT IT TOOK A HUGE AMOUNT OF TIME AND HE BASICALLY HE HE WAS THE FIRST ONE TO REALISE THAT THESE THESE GUYS ARE PRETTY SLOW TO TO DO THESE THINGS SO HE HE HE JUST UH HE JUST UH PUT HERE THE P. MAKE ENVIRONMENT AND HE DIDN'T STICK TO ANY CLUSTER OR ANYTHING HE JUST PUT P. MAKE AND RUN IT ON UH ON ALL THE MACHINES HERE SO AT SOME POINT HE WAS USING ALL THE AVAILABLE MEMORY BY ANY MISTAKE YOU KNOW SO AT TH IN THE MORNING ALL THE MACHINES WERE WERE JUST STUCK D NO ONE COULD EVER M MOVE THE MOUSE RIGHT AND BECAUSE HE WAS DOING EVERYTHING IN MATLAB SO IT WAS AGAIN TEN TIMES MORE DEMANDING THAN C. PLUS PLUS AND THEN MAYBE YES MAYBE NO I DON'T IT'S HARD TO SAY MM BUT HE DID HE WROTE IT WELL BUT ANYWAY ANYWAY BECAUSE I W I IN THE CODE THAT I WROTE I WAS LIKE PLAYING ALSO WITH IF IF THE MAT MATRIX IS PARSE I REALLY DON'T USE IT ALL I JUST MULTIPLY FROM HERE TO HERE FROM HERE TO HERE NOT TO MATRIX P MY MATRIX AND THEN I I JUST OPTIMISED IT A BIT AND ALSO BLAST LIBRARIES AND ALL THESE STA THINGS BUT OKAY OH WELL WHATEVER BUT THE T WHEREAS I MEAN THIS IS SOMETHING WHICH WE NEVER TALK ABOUT RIGHT I HEAR IT HOW MUCH WORK UH DOES PUT IN UH HERE BECAUSE IT'S TRUE IT'S TRUE THIS THAT UH THAT THINGS SPED UP TREMENDOUSLY SINCE I CAME I MEAN UH OF COURSE PARTIALLY BECAUSE THEY STARTED TO BUY SOME MORE UH MORE HARDWARE BUT ALSO BE P SOME AT LEAST SOME PEOPLE BASICALLY KNOW HOW TO UH UH WRITE FASTER PROGRAMS UH THIS IS FANTASTIC NORMALLY IT WOULD TAKE HOUR AND A HALF MM-HMM YEAH NO NO TODAY IT WAS OVER ONE HOUR IT'S JUST LIKE TEN TIMES LESS MAYBE OR FIVE TO TEN TIMES LESS BUT STILL STILL YOU CAN YOU CAN FIVE TIMES MORE COMPUTE YOU GO BACK TO PRAGUE FOR A WHILE AND THEN DID YOU GET ANYTHING IN F IN FRANCE I GOT SOME IDEAS BY THE WAY I YEAH YEAH YEAH I I DIDN'T TRY TO I DIDN'T EVEN MAIL TO TO CHERNOTSKY I MUST SAY UH I JUST TALKED TO ONE GIRL THERE WHICH TOLD ME THAT HE WOULD BE POSSIBLY ABLE TO FIND ME A JOB THERE ANY ANY JOB LIKE RELATED MAYBE TO FIELD BUT JOB NOT NOT ANYTHING ANY RESEARCH SO IF IF NOTHING THEN THEN I COULD BE ABLE TO GET THE JOB SOMEWHERE YEAH PROBABLY YEAH BUT T S BUT YEAH UM 'KAY SO JOEL YOUR MAIN BASICALLY THING IS AS I TOLD YOU TO T UH WHEN WE WERE WALKING THAT UH THAT WHAT WHATEVER PETR DID THAT IT DOESN'T DIE BUT IT I IT CARRIES
