Abstract

omen’s movements advocating for gender equality in an intersectional way, where feminism should meet the experiences of this demographic of women, is at her intersection of <b><i>culture</i></b>, race, and gender oppression that is at a cross-road with the traditional, white, female-focused movement in the first (1840–1920), second (1962–1980s), and possibly arguably even third (1990s) <a href="https://www.history.com/news/feminism-four-waves">waves of feminism</a> that mainly all focused on the experiences of oppression from a predominantly western white female perspective alone.</p><h1 id="034e">Female Gender Oppression: Population Control via The Medical Profession</h1><p id="531d">Kim Jiyoung’s friend falls pregnant, and what a drama it caused; this was around the time when the government implemented “birth control” policies they called “family planning.” Abortion was legal for medical related reasons. What if I told you that being born female was also considered a “medical problem” and a reason for her friend to consider abortion? And clearly some medical professionals felt the same way. The author cites this as a common dilemma for women throughout the 1980s-1990s. While the author does not go deep into this subject as part of the plot, I did do some investigation myself into this. According to the <i>Feminist Majority’s</i> short report they released in <a href="https://feminist.org/news/korean-women-pressured-to-abort-girl-babies-to-try-for-sons/">January 1997</a> they confirmed that:</p><blockquote id="cdaa"><p>“Although fetal sex identification and abortion are against the law in South Korea, women continue to feel pressure to abort girl fetuses in order to try for sons.”</p></blockquote><p id="5cf4">Also</p><blockquote id="fe88"><p>“Compared to a natural ratio of 105 boys born for every 100 girls (which later evens out to 1:1 since boys die earlier), some regions in South Korea have rates of 125 boys born to every 100 girls resulting in 30,000 fewer girls born each year than would be the case without sex-influenced abortions.”</p></blockquote><p id="9143">And</p><blockquote id="41f7"><p>“A Chinese government report in 1992 found the ratio in China at 118.5 boys to 100 girls, statistics which embarrassed the government enough that it never formally released the results.”</p></blockquote><p id="9f55">When looking the pressure Korean women face to have sons, taking a simple glance at the birth rate ratio would lead a critical mind to see the ratio supports the argument that the medical profession had what I would call “a silent compliance” to help embed and maintain female oppression, by aborting female babies. Sure, no doctor with his or her head on straight will announce to the world, “come to me for female terminations, I’ll gladly help you.” But that doesn’t mean it wasn’t going on. The stats on the birth rate ratio show that at this point in time, in the nineties when the rates were released, female terminations must have been carried out at a high rate.</p><p id="1f4d">What is key to note about the male to female birth rate ratio is: any parent will probably remember the scan they were given when their fetus was eighteen to twenty weeks old. Around this time, when you’re offered a nice photo of the baby, you can also <a href="https://www.healthline.com/health/pregnancy/when-can-you-find-out-sex-of-baby#medical-tests">learn the sex of the baby</a>. For the Korean women it’s at this point that terminations logically must have been happening for females babies. This is as late as five months into pregnancy; abortions done then come with a higher risk to the mother as stated in the research done by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9614144/"><i>Frontiers in Women’s Global Health’s</i></a><i> </i>2022 study across southern Ethiopia. Their report asserts that:</p><blockquote id="eb57"><p>“Second-trimester abortion accounts for 10–15% of all induced abortions, with varying rates across countries, and is responsible for two-thirds of major abortion complications. It is also associated with higher medical costs, morbidity, and mortality rates than first-trimester abortion.”</p></blockquote><p id="e44f">With only 10–15 % as a norm for abortions at this stage, we can assume it’s not the norm globally. The <a href="http://aidtowomencenter.org/abortion-secondtrimester"><i>Aid to Women Centre</i></a> also cites a lot of risks and complications post abortion for women who have second trimester abortions. The Korean women have been subjected to a health risk, for the sake of maintaining their cultural patriarchy, which is not something we see a lot of for the western woman, in western culture.</p><p id="d54f">If we further compare the western gender oppression to the Koren women’s via the outcomes for female babies, and the medical profession’s willingness to partake in oppression, and lastly the health risk of a woman choosing late termination (even if the practice was more common in the eighties-nineties), you see that this type of oppression is not a cultural norm in the west. It could be argued that pressure should be placed on the Korean medical profession for better regulation of abortion practices.</p><p id="67d5">For Korean women their intersection of cultural oppression includes a key aspect western woman do not have. Which is: from the womb, females leave a bad taste in society’s mouth. Whether you have a girl or a boy, generally speaking, for the western woman it is a cause for celebration, not abortion.</p><figure id="d363"><img src="https://cdn-images-1.readmedium.com/v2/resize:fit:800/1*i1XzuPmk2jAonENWjAYxTA.jpeg"><figcaption>Photo by <a href="https://unsplash.com/@thatsherbusiness?utm_content=creditCopyText&amp;utm_medium=referral&amp;utm_source=unsplash">That’s Her Business</a> on <a href="https://unsplash.com/photos/white-ceramic-mug-on-white-ceramic-plate-8KHPeh9mNvs?utm_content=creditCopyText&amp;utm_medium=referral&amp;utm_source=unsplash">Unsplash</a></figcaption></figure><h1 id="3e35">The Role of Korean Women: Their ‘Double Jeopardy’ and Work</h1><p id="a483">Being a woman with another characteristic that can be used for oppression (such as race or class), has been defined as ‘a double jeopardy’ by the black feminist Frances. M. Beal, in her work <a href="https://en.wikipedia.org/wiki/Double_Jeopardy:_To_Be_Black_and_Female"><i>Double Jeopardy: To Be Black and Female (1969)</i></a><i>. </i>In relation to the Korean woman, her double jeopardy is being female and living in a <b>culture which defines her role in a specific way</b>. Korean females are often not shunned for working or discouraged from working. In the west, the “right to work” caused a ruckus from predominantly white women in the second wave (1963–1980s) of feminism, against white men’s oppression. But the Korean woman is often expected to work, not for herself but to support the males in her family so that <b>they can progress</b> in life. Woman will work in substandard conditions with risks to their health, for terrible wages, to gain a few pennies to rub together in the contribution pot of male success. In <i>Kim Jiyong, Born in 1982, </i>the author writes:</p><blockquote id="b3ac"><p>“This was at a time when people believed it was up to the <b>sons</b> to bring honour and success to the family. The family’s wealth and happiness <b>hinged upon male</b> success. The <b>daughters</b> gladly supported the male siblings.”</p></blockquote><p id="e10a">This narrative comes in a scene where we see a Korean lady struggling with work to provide for a man and fulfill her cultural duty. Yet she could not dream for herself, and she could not be a success, and she could not work in the profession of her own desire.</p><p id="f2e2">Where culture meets feminism from this angle of work and roles in society, is a need to recognise the “double jeopardy” for Korean women — that is focused on <b>cultural roles and norms</b> for her as a woman in the world of work. Outside of being white and female, the cultural roles for women often do look very different for the black, brown, and minority woman; I have said this before and will keep saying it.</p><p id="bac4">The Korean woman is in a similar position of not being able to pursue her dream of her ideal career, just like white feminists fought for the right to work against white men. However, what is unique to women in different communities is that it is <b>a necessity for them to work and they are expected to</b>, <b>but not for them</b>, for the <b>patriarchy</b>, in the context of Korean women. For black women this looks different which I do plan to write about in a future story. Sticking to the Korean women’s plight and experience, now, if this is not oppression worth noting, or checking the patriarchy’s behaviour to show them how it damages the Korean women, then I don’t know what is.</p><p id="f1a9" type="7">Where culture meets feminism from this angle of work and roles in society, is a need to recognise the “double jeopardy” for Korean women</p><h1 id="7d11">Education of Korean Girls and Women</h1><p id="7ff4">In addition to being expected to work minor jobs to support the patriarchy, the Korean woman’s education is sacrificed. Boys are prepared for school with the right equipment, books, lunches etc., as mentioned earlier. Later on, when it comes to further education, boys are encouraged to attend higher education to access the degrees that will land them high paying jobs. While girls are not put in this position, but it’s fine for them to work on lower paying jobs, in risky environments, to support this cultural norm and the patriarchy. If you’re a woman in the west, tell me: when was the last time this was expected of you, as a woman?</p><h1 id="3ac5">How Cultural Oppression Embraces Sexual and Physical Harassment</h1><p id="7490">One of the most heartbreaking things about the cultural oppression Korean women face, for me as a reader of the author’s work, was how vivid it was that sexual and physical harassment is something Korean girls should just get used to. It appeared to be a cultural norm, something that starts from an early age and doubles down on the learning Korean girls gain around their status being lower than boys.</p><p id="fe7a">It appears that if a girl or woman is a victim, she is questioned over what she possibly could have done to bring the assault on herself. We do see this today in the western culture at times; it would be a lie to say we don’t.</p><p id="a618">The difference is when comparing the western woman’s potential experience of the doubt around her experiences, and the Korean woman’s, culturally it seems more acceptable to disbelieve a Korean woman. Also, it’s more culturally acceptable to physically/sexually harass women. For women, it’s almost like harassment is an expected life experience that is a woman’s responsibility to avoid.</p><p id="669c">One of the most dramatic examples of this embedded culture was while Kim Jiyoung was at school. She was bullied by a boy, and the teacher blamed her. The truth only came out when another young girl was brave enough to raise her hand and say what she saw. Later on, we follow young Kim Jiyong’s story as she makes her way home from school. A boy follows her, and even attempts to intimidate her with sexual advances on the bus. Her father’s response is to ask her, “what did you do?” for her to bring on his attack.</p><p id="4479"><a href="http://dis.hanyang.ac.kr/lyceum-vol-1/sexual-harassment-in-south-korea/"><i>The Hangyang Dis Division of International Studies</i></a> backs up the ex

Options

periences of Kim Jiyoung; they reported in 2018:</p><ul><li>a sexual assault is reported across south Korea at a rate of 3 cases an hour.</li><li>98% of assaulters being men, and 86% of victims being women.</li><li>One of the most common places of assault happening in the workplace.</li></ul><p id="cca9"><a href="http://dis.hanyang.ac.kr/lyceum-vol-1/sexual-harassment-in-south-korea/">The <i>Hangyang Dis Division of International Studies </i></a>also says in their report:</p><blockquote id="cdd6"><p>“Before you ask yourself why these women don’t speak-out, you must first understand the culture background of their society.”</p></blockquote><p id="1008">Supporting the last point above, we see workplace sexual harassment when Kim Jiyoung enters the world of work, in the field of marketing. A male security guard takes it upon himself to install secret cameras in one female toilet, then uploads the images to a pornographic site. He shares his assault with other men in the workplace, the cat is only let out of the bag when the word reached Kim Jiyoung’s female friend via her boyfriend — who warned her to use a different bathroom. The women engage in sexual assault litigation against the company; then the male CEO of the company responds to the women who were victims of the pornographic website experience:</p><blockquote id="62fc"><p>“It’ll ruin this company’s reputation if word gets around in the field, The accused male employees have families and parents to protect, too. Do you really want to destroy people’s lives like this?”</p></blockquote><p id="3a9e">What we see here is sexual harassment at its finest, with a spoonful of misogyny mixed in. It could be argued that any boss would respond like this, especially a male boss, to protect their company. Yet the men themselves who were part of the sexual assault admitted what they did but see no wrongdoing — that’s the cultural dynamic around overlooking women and sexual assault the <i>Hangyang Dis Division of International Studies</i> is probably referring to in their citation about understanding culture, above.</p><p id="7201">When compared to western culture, this is not something that would be taken as lightly. It could even be argued that a CEO (for the good of their company) is more likely to disassociate with the offenders of sexual assault to protect their brand. <a href="https://en.wikipedia.org/wiki/Sean_Combs">Sean ‘Puffy’ Combs,</a> the American rapper who currently at the time of writing has <a href="https://www.latimes.com/entertainment-arts/business/story/2023-12-06/sean-diddy-combs-sexual-assault-harve-pierre-fourth-woman">four sexual assault</a> cases against him, has been dropped from all of his lucrative money making deals by big companies. <a href="https://en.wikipedia.org/wiki/Russell_Brand">Russell Brand,</a> who is also caught up in sexual assault cases, lost his <a href="https://www.theguardian.com/culture/2023/sep/19/youtube-suspends-russell-brand-revenues-channel">YouTube monetised channels</a>, and <a href="https://en.wikipedia.org/wiki/Jonathan_Majors">Jonathan Majors</a> was <a href="https://www.independent.co.uk/arts-entertainment/films/news/jonathan-majors-assault-projects-dropped-b2324039.html">dropped from his acting roles</a> due to his accusations of sexual assault; this has all happened in 2023 at the time of writing this. In the west what we see here is a different response to women’s sexual assault. We have a “cancel culture” for men. Korean has a “what did we really do wrong? You can’t cancel us” culture. For the fourth wave feminist, this is something to challenge when culture meets feminism. The patriarchy needs checking around their handling — literally of women and their bodies, which they feel are free to access for all.</p><figure id="550f"><img src="https://cdn-images-1.readmedium.com/v2/resize:fit:800/1*fuRradtidxYvIirUNUppbg.jpeg"><figcaption>Photo by <a href="https://unsplash.com/@sandym10?utm_content=creditCopyText&amp;utm_medium=referral&amp;utm_source=unsplash">Sandy Millar</a> on <a href="https://unsplash.com/photos/gold-wedding-band-on-white-textile-8vaQKYnawHw?utm_content=creditCopyText&amp;utm_medium=referral&amp;utm_source=unsplash">Unsplash</a></figcaption></figure><h1 id="afc3">About Married Life and Korean Women’s Oppression</h1><p id="736c">For the Korean woman, she is often forced to give up work (if she has been lucky enough to find it), once she gets married. The pressure to get married is high, and her choice between work, marriage, and children is due to cultural expectations; this is not a woman who can have it all in any way shape or form. Once a woman is married it is an expectation, demand, and almost her duty to now start popping out babies — that are male, mind you. So that he can “bring the success, prosperity, and respect to the family,” as mentioned earlier.</p><p id="f56f">It was around 2014 when Kim Jiyoung finally secured work, battling through the sexism she faced as a Korean woman, which I deep dive into in my essay, <a href="https://readmedium.com/is-feminism-to-blame-for-korean-women-taking-down-the-patriarchy-870090bcc034?sk=ab5fcd0da5d394069b13b6107ad7dbe3"><i>Is Feminism to Blame For Korean Women Taking Down The Patriarchy</i></a><i>. </i>Then Kim Jiyoung left work, just as one in five Korean women quit their job citing: marriage, pregnancy, childbirth and care, or the education of their younger children, according to <a href="https://eng.kwdi.re.kr/inc/download.do?ut=A&amp;upIdx=101628&amp;no=1"><i>Women’s Lives Through Statistics in 2015, Statistics Korea</i></a><i>. </i>Around the time Kim Jiyong was faced with life changes the author asserted that:</p><blockquote id="fe06"><p>“The workforce participation rate of Korean women decreases significantly before and after childbirth. Its percentage starts at 63.8% for women aged twenty and twenty-nine, drops to 58% for women aged thirty to thirty-nine.”</p></blockquote><p id="da10">What this shows is that when culture meets feminism in this area for women, there is greater pressure, expectation, and demand for them to leave work to have male children, and if they do return to work after birth — to work to support their son’s progression. The latter, the author demonstrates, often means taking a lower paying job and giving up a career. Kim Jiyoung went from being a marketing executive in a male, sexist, environment — but she made it! — to considering part-time work in an ice cream parlour. This expectation is not a cultural norm for many of us western women, but one we need to be sensitive to, if we are to be inclusive female advocates.</p><p id="c887">Husbands also add to this pressure to leave work but fail to see what their wives are giving up. This plays out for readers clearly when married Kim Jiyoung is pressured by in-laws to have a child, then discusses it with her husband. They have barely been married five minutes at this point:</p><blockquote id="0c7b"><p>“And what will you be giving up <i>Oppa</i>?</p></blockquote><blockquote id="844d"><p>“What?”</p></blockquote><blockquote id="5852"><p>“You said don’t just think about what I’ll be giving up. I’m putting my youth, health, job, colleagues, social networks, career plans, and future on the line. No wonder all I can think about are the things I’m giving up. But what about you? What do you lose by gaining a child.”</p></blockquote><p id="e500">Her husband, true to his culture, did not see Kim Jiyoung’s personal goals, dreams, and rights to work go down the pan, in favour of producing child after child until she has a boy. Only to then take work well below her skills to provide for the male child.</p><p id="3643">For intersectionality to really make an impact in this fourth wave of feminism, as I said in the opening, eyes must be opened, ears must be fixed, and the advocate for women’s rights must step outside not only their <a href="https://readmedium.com/the-intersection-when-race-meets-feminism-the-unfinished-conversation-d39e2dda8062?sk=ecfa9780caf2ab4cc78d4d86dc2d29b3">race</a>, class, sexuality, able body, but also their<b> culture</b> to understand how oppression looks different for different demographics of women. This is how the patriarchy’s behaviour oppresses some women; the men do nothing to change a son’s position being more valuable than daughter’s from the moment they are conceived. They take this status norm in their culture as chance to exploit women sexually, physically, and even financially with Korea having the largest gender pay gap in the Asian countries. The patriarchy’s behaviour is culturally harming women; this is not my opinion, this is based on the data, statistics, and evidence presented. My message to the patriarchy is: don’t argue with me, argue with the evidence, and do something about it.</p><p id="0517"><b>What are your thoughts and feelings now that you’ve seen cultural oppression by reading these words?</b></p><p id="319a"><i>Thanks for your readership, I hope my writing gave you something to think about.

做資料科學應該知道的畫樹模型的三種方法

source

嗨,大家好,轉眼間又到了要撰寫下篇文章的時間了,也來到了11月,這個可怕的2020也即將進入尾聲,祝福每個人都能夠身體健康。

今天的文章是來自於在某天上班時同事所提的需求,這個需求是我之前已經有花過時間解決的問題,但是當下因為很久沒碰了,所以完全忘記了怎麼去解決,導致花了許多時間在重拾回憶,為了避免以後再次忘記,我決定要把它記錄下來,讓除了我,以後大家也都能用得到。

那這個需求是什麼呢?就是要怎麼把我們使用的樹模型裡面樹的決策流程畫出來,讓我們可以不僅僅檢視辨識重要性,也可以同時觀察決策樹的方向和篩選條件是符合或超出我們的預期,也可以根據這些決策條件去制定相關的方案。

今天的文章撰寫過程如下:

(1) 畫圖前準備

(2) 資料集

(3) Scikit-Learn畫圖

(4) LightGBM畫圖

(5) XGBoost畫圖

(6) 結論

(1) 畫圖前準備

為了能夠在不同套件下都能夠使用Python來畫出樹,當需要報告或知道其決策條件時,就可以使用該些方法來成功得到樹圖。你必須利用Graphviz這個套件來幫助你完成。

What is Graphviz?

Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

source

為了能使用這個套件,你必須要先下載它

pip install graphviz # 在本機端上開啟cmd並輸入此語句
conda install graphviz # 可以使用anaconda來run graphviz

都key完之後,可以檢測其是否被成功下載

dot -v

Windows

Windows用戶可能需要注意一下,因為使用Graphviz會有必須要加入到系統環境變數上的問題,所以你可以在每次要畫圖時手動加入,你必須要找到Graphviz在絕對路徑上的位置在哪裏。

import os
os.environ["PATH"] += os.pathsep + 'C:/ProgramData/Anaconda3/Library/bin/graphviz' # 這是我Graphviz的位置

(2) 資料集

當然,要用畫出模型的圖的話,你必須要有模型,要有模型的前提也是,你需要有資料集可以給你訓練。

這整篇3種不同樹模型的演算法都是使用Iris當做資料集,基本上就是學機器學習的必備資料集,輕鬆好懂。

from sklearn.datasets import load_iris
iris = load_iris()
x = iris['data'][:, 2:]
y = iris['target']

(2) Scikit-Learn畫圖

首先會是以Scikit-Learn這個經典的套件來畫圖先,也是用樹模型畫決策樹功能最豐富的套件之一。

訓練模型

from sklearn.tree import DecisionTreeClassifier
model = DecisionTreeClassifier(max_depth=2, criterion='entropy')
model.fit(x, y)

接下來的code,會將你的樹模型的圖輸出成dot檔

from sklearn.tree import export_graphviz
export_graphviz(model, # 模型 
            out_file='圖/sklearn_tree.dot', # 輸出到dot檔
            feature_names=iris.feature_names[2:], # 顯示Feature Names
            class_names=iris.target_names, # 顯示target Name
            rounded=True, # 開啟round
            proportion=False, # 不顯示比例 顯示target的數量
            precision=2, # 小數點後第二位
            filled=True # 是否根據Target來填顏色)

在Jupyter notebook中使用cmd將dot檔轉成png檔

from subprocess import call
call(['dot', '-Tpng', '圖/sklearn_tree.dot', '-o', '圖/sklearn_tree.png'])

並在Jupyter notebook中打印出Image

from IPython.display import Image
Image(filename='圖/sklearn_tree.png')

(3) LightGBM畫圖

訓練模型

lgb_train = lgb.Dataset(x, y)
params={'objective':'multiclassova', 'num_class':3}
model = lgb.train(params, lgb_train)

LightGBM可以有plot_tree這個function可以給我們快速畫圖使用

import matplotlib.pyplot as plt
lgb.plot_tree(model, dpi=600,
              show_info=['split_gain', 'internal_value', 'internal_count', 'internal_weight',
              'leaf_count', 'leaf_weight', 'data_percentage'])
plt.savefig('圖/lightgbm_tree.png')
plt.show()

LightGBM是透過Gradient Boosting的方式去建構模型,所以會有好幾棵樹去優化模型,你可以在plot_tree裡面透過tree_index這個parameter指定你要畫第幾棵樹,通常是畫在第一棵樹或是在Best iteration的那棵樹。

(4) XGBoost畫圖

訓練模型

model = xgb.XGBClassifier()
model.fit(x, y)

XGBoost可以有plot_tree這個function可以給我們快速畫圖使用

import matplotlib.pyplot as plt
xgb.plot_tree(model, num_trees=2) # 畫出第二棵樹
plt.savefig('圖/xgboost_tree.png')
plt.show()

(5) 結論

That’s it! 這樣就輕鬆寫意的學完在機器學習中最重要的三個訓練樹模型的Library畫圖方法了,不用記得沒關係,只是如果在未來,當你我有畫決策樹的圖的需求時,可以想到這篇文章會快速幫你完成你的需求喔!

輕鬆又不喪失樂趣的一篇文章,謝謝你看到最後,不一定要每個禮拜都強求自己學習非常高深的技術,學點簡單的,提高自己的自信心也不錯喔!

一樣,如果有問題都可以寄信給我喔,我的信箱是[email protected],Strive for greatness!
