Sharpening Occam's razor-a diagnostic dilemma

Payal Sen, Uddalak Majumdar, Patrick Rendon, Ali Saeed, Akshay Sood
2016 Southwest Journal of Pulmonary and Critical Care  
Countering Occam's Razor, Dr. John Hickam said "Patients can have as many diseases as they damn well please!" (17) .  ...  Physicians often search for Occam's Razor, i.e., to have a single diagnosis explain all clinical manifestations in an individual patient.  ...

Sharpen statistical significance: Evidence thresholds and Bayes factors sharpened into Occam's razor

An idealization of Occam's razor in terms of the entropy of the data distributions tends to favor the null hypothesis over the alternative hypothesis.  ...  Occam's razor suggests assigning more prior probability to a hypothesis corresponding to a simpler distribution of data than to a hypothesis with a more complex distribution of data, other things equal  ...  for the simplicity of distributions as motivated by Occam's razor.  ...

Model averages sharpened into Occam's razors: Deep learning enhanced by Rényi entropy

David R. Bickel
2019 Zenodo  
The proposed ensemble method is based on Occam's razor idealized as adjusting hyperprior distributions over models according to a Rényi entropy of the data distribution that corresponds to each model.  ...  Occam's razor addresses that problem by adjusting the prior distribution over models for the complexity of their predictive distributions, as described in Section 2.  ...  That one-to-one correspondence between Bayesian models and parameter values presents the opportunity to modify the prior and posterior distributions according to the formalization of Occam's razor found  ...

Occam's Razor in science: a case study from biogeography

A. Baker
2006 Biology & Philosophy  
Part 1 is devoted to sharpening and clarifying Occam's Razor as a principle of parsimony, and to contrasting it with other related simplicity principles.  ...  Doubtless there are other relevant case studies whose examination would help sharpen our preliminary assessment of the status of Occam's Razor in science.  ...

HOW IS HAIR GEL QUANTIFIED?

2011 Connectionist Models of Neurocognition and Emergent Behavior  
In the context of model comparison, to abide by Occam's Razor is not the same as adhering to simplicity.  ...  Looked at in another way, Occam's Razor emphasizes a very strong bottom-up (i.e., data-driven) orientation.  ...
