 The presentation is 
 titled "A New Subsampling Technique for Random 
 Points and Optimal Least Squares Approximation 
 of High-Dimensional Functions."\n

 We provide a new general upper 
 bound for the minimal L2-worst-case recovery 
 error in the framework of RKHS, where only 
 n function samples are allowed. This quantity 
 can be bounded in terms of the singular numbers 
 of the compact embedding into the space of 
 square integrable functions. It turns out that 
 in many relevant situations this quantity 
 is asymptotically only worse by square root 
 of log(n) compared to the singular numbers. \n\n
