16 February 2013 Introduction The Elements of Statistical Learning is an in?uential and widely studied book in the ?elds of machine learning, statistical inference, and pattern recognition. It is a standard recommended text in many graduate courses on these topics. It is also very challenging, ...
and bias do not need to be independent Elements of Statistical Learning • 2.6.2 Supervised Learning • For this book = function approximation • If samples size is large and dense, all solutions tend to limiting conditional expectation • when N is finite, eligible solutions must be rest...
Exercise Solutions Ex. 2.1 (target coding) The authors have suppressed the context here,making the question a little mysterious. For example,why use the notation ¯ instead of simply y?We imagine that the background is something like the following.We have some input data x. Some algorithm ...
The Element of Statistical Learning – Chapter 2 oxstar@SJTU January 3, 2011 Ex. 2.1 Suppose each of K-classes has an associated target tk, which is a vector of all zeros, except a one in the kth position. Show that classifying to the largest element of y? amounts to choosing the ...

To address these challenges, here we introduce MATES, a deep-learning approach that accurately allocates multi-mapping reads to specific loci of TEs, utilizing context from adjacent read alignments flanking the TE locus. When applied to diverse single-cell omics datasets, MATES shows improved ...
