The phrase "assumption classes" is correct and usable in written English.
It can be used in contexts related to education, programming, or theoretical discussions where categories or types of assumptions are being classified.
Example: "In our research, we identified several assumption classes that influence the outcomes of our experiments."
Alternatives: "categories of assumptions" or "types of assumptions".
We find VarMixt more subtle: it makes the assumption that classes of genes can be identified based on similar response to the various sources of variability (mixture model); the variance of each homogeneous class is then accurately estimated from a large set of observations; the individual gene variance is then replaced by its "class" variance.
Opponents of the Marxist view, however, assert that it relies on a dubious teleological conception of history and that its assumption of class agency is nonsensical because classes are mobilized only through the individuals who constitute them.
An assumption of class effects presupposes that the effect of each intervention within a class is identical.
For the thoughtful left, such statistics are beginning to challenge the old assumption that class must always be the only social divide that counts.
Traditional learning approaches based on the assumption that class priors are stationary lead to sub-optimal solutions if there is a mismatch between training and future (real) priors.
The advantage of this method is that it does not rely on the identifying assumption that class size is not influenced by parents.
The estimates by Bingley, Jensen and Walker are based on the assumption that class size affects wages by changing years of schooling.
Third-way advocates proceed from the bedrock assumption that class-based politics is over and that the goal of economic policy should be, as Democratic Leadership Council chief Al From puts it, to "expand the winner's circle". This is elitist nonsense, the Panglossian burblings of those who follow the Tao of the limitless Dow.
It is based on the assumption that class II molecules are directly involved in the etiology and pathogenesis of autoimmune disease.
Thus we require neither upfront dimensionality reduction schemes nor the restrictive assumption of class conditional feature independence in the Naïve Bayes model.
