For special classes of linear systems it is possible to find optimal Krylov methods with short recurrences.

We present the … WebbAt around. 7:22. in the video, Sal is talking about an outlier, and he mentions that it skews the data, it drags the mean upward. Then it suddenly all made sense. The data in the tail is off centered from the normal distribution, and it is literally skewing the mean in that direction. Anyway, it made a lot more sense to me when I saw that.

Webbdata is not evenly partitioned across tasks. This type of skew, called data skew, typically affects reducers since map tasks are normally assigned same-size chunks of input data. For reducers, the problem can occur either when a reducer processes a larger number of keys or a larger number of values than other reducers. In our work, WebbSkewness is a measure of the asymmetry of the data around the sample mean. If skewness is negative, the data spreads out more to the left of the mean than to the right. If skewness is positive, the data spreads out more to the right. The skewness of the normal distribution (or any perfectly symmetric distribution) is zero.
