<p>The mean value of a convex function is never lower than the value of the convex function applied to the mean</p>
<p>What is the name of the following fact: "The mean value of a convex function is never lower than the value of the convex function applied to the mean"?</p>

<p>"Many people working on network pruning observed that, starting from a wide network and pruning it, one obtains better performance than training the slim, pruned architecture from scratch (random initialization).
According to the BLANK, good performance results from lucky initialization of a subnetwork or subcomponent of the original network. Since fat networks have exponentially more component subnetworks, starting from a fatter network increases the effective number of lottery tickets, thereby increasing the chances of containing a winning ticket. According to this hypothesis, pruning effectively identifies the subcomponent which is the winning ticket."</p>

<p>What is a dilated convolution?</p>
<p>In a regular convolution, the kernel is applied at every position. In dilated convolutions, we apply the kernel only every l steps. This means that as you add layers, the receptive field of upper units increases in size exponentially with depth instead of linearly.</p>

Time series: "One issue with using mathematical transformations such as Box-Cox transformations is that the back-transformed forecast will not be the [BLANK] of the forecast distribution. In fact, it will usually be the [BLANK] of the forecast distribution (assuming that the distribution on the transformed space is symmetric)"

Time series: "A good forecasting method will yield residuals with the following properties: * [BLANK] * The residuals have zero mean. If the residuals have a mean other than zero, then the forecasts are biased."
A good forecasting method will yield residuals with the following properties: * The residuals are uncorrelated. If there are correlations between residuals, then there is information left in the residuals which should be used in computing forecasts. * The residuals have zero mean. If the residuals have a mean other than zero, then the forecasts are biased.

Time series: the best way to get a unit-independent error measurement of a time series forecast is to use mean absolute scaled error (MASE) where the error for each prediction is divided by the mean absolute error of the naive "repeat the last point" prediction on the training data.
Time series: "If a transformation has been used, then the prediction interval should be computed [BLANK]"
Time series: "If a transformation has been used, then the prediction interval should be computed on the transformed scale, and the end points back-transformed to give a prediction interval on the original scale. This approach preserves the probability coverage of the prediction interval, although it will no longer be symmetric around the point forecast."
