The Relative Importance of Aggregate and Sectoral Shocks ...

The reduction in aggregate volatility in the U.S. that occurred in the mid 1980s was accompanied by a shift in the relative importance of aggregate and sectoral shocks. Using a principal components decomposition of sectoral IP data, we document that the contribution of aggregate shocks to the variance of aggregate output declined from about

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

In view of the importance of aggregate density to the mechanical properties of concrete, it is necessary to determine the aggregate density at any point in concrete or any cross-section of a concrete element. Once the aggregate density is known, some other mechanical properties of the concrete can be determined based on the theory of micro-mechanics. This paper attempts to simulate aggregate ...

Feature Selection with sklearn and Pandas | by .Traduire cette page

Feature selection is one of the first and important steps while performing any machine learning task. A feature in case of a dataset simply means a column. When we get any dataset, not necessarily every column (feature) is going to have an impact on the output variable. If we add these irrelevant features in the model, it will just make the model worst (Garbage In Garbage Out). This gives rise ...
