New Weathers: Lectures from the Naropa Archive
為了解決Cross entropy 的問題,作者 這樣論述:
Anne Waldman, poet, performer, professor, literary curator, and cultural activist, has been a prolific and active poet and performer many years, creating radical hybrid forms for the long poem, both serial and narrative, as with Marriage: A Sentence, Structure of the World Compared to a Bubble, Mana
tee/Humanity, and Gossamurmur, all published by Penguin Poets. She is also the author of the magnum opus The Iovis Trilogy: Colors in the Mechanism of Concealment (Coffee House Press 2011), a feminist "cultural intervention" taking on war and patriarchy which won the PEN Center 2012 Award for Poetry
. Recent books include: Voice’s Daughter of a Heart Yet To Born (Coffee House 2016) and Trickster Feminism (Penguin, 2018). She has been deemed a "counter-cultural giant" by Publisher’s Weekly for her ethos as a poetic investigator and cultural activist, and was awarded the American Book Award from
the Before Columbus Foundation for Lifetime Achievement in 2015. She has also been a recipient of The Shelley Award for Poetry (from the Poetry Society of America), a Guggenheim Fellowship and the Elizabeth Kray Award from Poets House, NYC in 2019. Waldman has also been at the fore-front many decade
s in creating poetic communities and has focused on the necessity of archival practices to insure the memory of some of the 20th and 21st century’s most precious literary histories and oral recordings. She was one of the founders of the Poetry Project at St Mark’s Church In-the-Bowery, and its Direc
tor a number of years and then went on to found The Jack Kerouac School of Disembodied Poetics at Naropa University with Allen Ginsberg and Diana di Prima in1974 and went on to create its celebrated MFA Program. She has continued to work with the Kerouac School as a Distinguished Professor of Poetic
s and Artistic Director of its Summer Writing Program. During the global pandemic she and co-curator Jeffrey Pethybridge have created the online "Carrier Waves" iteration of the famed Summer Writing Program. She is the editor of The Beat Book and co-editor of Civil Disobediences: Poetics and Politic
s in Action, and Beats at Naropa and most recently, Cross Worlds: Transcultural Poetics. She is a Chancellor Emeritus of the Academy of American Poets. She makes her home in New York City and Boulder, Colorado Emma Gomis is a Catalan American poet, essayist, editor and researcher. She is the cofound
er of Manifold Press. Her texts have been published in Denver Quarterly, The Brooklyn Rail, Entropy, and Asymptote among others and her chapbook Canxona is forthcoming from b l u s h lit. She was selected by Patricia Spears Jones as The Poetry Project’s 2020 Brannan Poetry Prize winner. She holds an
M.F.A. in Creative Writing & Poetics from Naropa’s Jack Kerouac School of Disembodied Poetics, where she was also the Anne Waldman fellowship recipient, and is currently pursuing a Ph.D. in criticism and culture at the University of Cambridge.
以機器學習手法預測保證通過系統級測試之晶片
為了解決Cross entropy 的問題,作者陳玥融 這樣論述:
近年來,如何在維持低百萬次錯誤率(DPPM)的水準下同時降低IC 測試開銷已成為半導體產業重要的研究課題。為了有效降低系統級測試(SLT)的成本,本論文提出一套利用機器學習手法來挑選出保證通過系統級測試之晶片的方法。我們我們首先以神經網路對輸入資料進行特徵空間轉換,並利用在該空間中資料集的分布特性篩選出保證會通過系統級測試的IC。被我們的手法判定為會通過系統級測試的IC 可跳過系統級測試直接進入出貨階段,進而降低整體測試時間。將我們的手法套用在業界資料後,可以成功篩選出1.8%的保證通過系統級測試的IC,且其中不包含測試逃脫(Test Escape)。

使用焦點損失函數與判別器訓練之增強型U-Net於斷層掃描影像之肝臟與肝腫瘤分割
為了解決Cross entropy 的問題,作者方啓瑞 這樣論述:
肝癌一直以來都是臺灣十大癌症死因中的前兩名,每年都有數千人因罹患肝癌過世。肝癌早期通常沒有明顯症狀,需要透過有效的篩檢工具來輔助診斷,例如電腦斷層掃描。然而一位病患的電腦斷層掃描可以產生數百張切片影像,使用人工篩檢是非常耗費精力的。本論文使用卷積神經網路應用在肝臟與肝腫瘤電腦斷層掃描的語義分割,以機器來輔助醫師診斷。研究方法是以U-Net為基礎架構,並同時加入了Squeeze-and-Excitation blocks以及attention gates這兩種模塊。另外在模型的訓練階段額外加入一個判別器,將語義分割模型與判別器視為生成對抗網路的框架來訓練,藉此提升語義分割模型的分割能力。透過實
驗比較,在測試資料的dice score中,同時加入Squeeze-and-Excitation blocks與attention gates並且在訓練時加入判別器機制,能讓肝臟的dice per case從0.9180上升到0.9385,肝腫瘤的dice per case從0.6020上升到0.6391。
