Matrix Norms vs. Vector Norms

甄亮利 2013-1-13 16:12

The four vector norms that play signi cant roles in the compressedsensing framework arethe $\iota_0$ ,the$\iota _1$, $\iota_2$, and$\iota_\infty$norms, denoted by$\|x\|_0$,$\|x\|_1$,$\|x\|_2$and$\|x\|_\infty$respectively. ...

人工智能与机器学习中一些问题的初步认识

热度 4 甄亮利 2012-11-14 23:34

虽然，在我自己一直都在做机器学习方面的研究，并总是听说统计机器学习。但为什么要叫“统计”机器学习？因为机器学习是“learn from the data”. 我们也可以将此看做是一个统计过程，然后得到一些“规律”，然后用这个“规律”去预测新输入的数据应该具有哪些属性。在机器学习中，我们建立一个数学模型后 ...

Basis Pursuit

热度 1 甄亮利 2012-3-24 20:03

From my first blog article- An introduction to sparse representation . We have noticed that the sparse coding for the input datasets is very useful to signal processing and machine learning. Zero norm is the direct solution for the sparse coding problem. However, D.L. Donoho proved that 1 norm ...
