Research of magnetic particle imaging reconstruction based on the elastic net regularization
نویسندگان
چکیده
Magnetic particle imaging (MPI) is an emerging medical modality that based on the non-linear response of magnetic nanoparticles. The reconstruction task inverse problem and ill-posed in nature. results state-of-the-art regularization model have many artifacts, time resolution should be improved significantly for real-time imaging. To this end, we first propose to use elastic net (EN) MPI reconstruction. obtain a good result with short time, truncated system matrix measurement research. We study quality by varying threshold values parameters. compare performance proposed Tikhonov least absolute shrinkage selection operator (LASSO) terms visualization indicators. EN largely no approximately 10 times LASSO 20 model. conducted demonstrated method yields higher than methods models.

Elastic-net regularization in learning theory
Within the framework of statistical learning theory we analyze in detail the so-called elastic-net regularization scheme proposed by Zou and Hastie [H. Zou, T. Hastie, Regularization and variable selection via the elastic net, J. R. Stat. Soc. Ser. B, 67(2) (2005) 301–320] for the selection of groups of correlated variables. To investigate the statistical properties of this scheme and in partic...

تحقیق حاضر به بررسی کاربرد روش ژانر-محور را در محیط آموزش زبان عمومی می پردازد.روش ژانر-محور به زبان آموزان کمک میکند که در زمینه خوانش پیشرفت کنند. بعضی از محققین معتقد اند که روش تدریس ژانر-محور به تدریج به زبان آموزان کمک می کند تا در درک ژانر های مختلف مهارت یابند (هایلند 2004).همچنین امروزه توجه روز افزونی به اهمیت استفاده از ادبیات در برنامه آموزشی زبان انگلیسی (esl/efl ) شده است. زمانی ک...
