Driving down Poisson error can offset classification error in clinical tasks

no code implementations9 May 2024 Charles B. Delahunt, Courosh Mehanian, Matthew P. Horning

To this end, it may have the option to offset its lower accuracy by increasing sample size to reduce Poisson error, and thus attain the same net clinical performance as a perfectly accurate human limited by smaller sample size.

How Good Are Synthetic Medical Images? An Empirical Study with Lung Ultrasound

1 code implementation5 Oct 2023 Menghan Yu, Sourabh Kulhare, Courosh Mehanian, Charles B Delahunt, Daniel E Shea, Zohreh Laverriere, Ishan Shah, Matthew P Horning

Adding synthetic training data using generative models offers a low-cost method to deal effectively with the data scarcity challenge, and can also address data imbalance and patient privacy issues.

Money on the Table: Statistical information ignored by Softmax can improve classifier accuracy

no code implementations26 Jan 2019 Charles B. Delahunt, Courosh Mehanian, J. Nathan Kutz

To explore this potential resource, we develop a hybrid classifier (Softmax-Pooling Hybrid, $SPH$) that uses Softmax on high-scoring samples, but on low-scoring samples uses a log-likelihood method that pools the information from the full array $D$.
