一些故事｜Some Stories

• 关于我是如何入门机器学习：在 2013 年的时候，由于某种契机，我接触到了 Coursera 并且学习了台湾大学林轩田教授的两门课程《机器学习基石》和《机器学习技法》。当时我大三，这两门课程对我来说相当有挑战性。庆幸的是，我遇到了一位名叫 Beader 的网友，他当时在台湾读研，也在学习这两门课。Beader 经常鼓励我并与我讨论作业，让我能够坚持下来并最终拿到了结业证书。后来，我们一起参加了 Kaggle 的 PAKDD 比赛（获得 Top 5%）以及 2014 年阿里巴巴第一届天池大数据竞赛（在 7,000 多支队伍中排名第 78）。当时我们队有三个人，另一位是他的女同学。后来，他们在一起了，再后来，他们结婚了：）

• How I Got Started with Machine Learning: Back in 2013, I stumbled upon Coursera and took two foundational courses by Professor Hsuan-Tien Lin from National Taiwan University: Machine Learning Foundations and Machine Learning Techniques. During my third year of university, I found the material quite challenging. Fortunately, I met a fellow learner online named Beader, who was a graduate student in Taiwan at the time. Beader encouraged me and we frequently discussed assignments, which helped me stay on track and eventually earn my certificates. Later, we teamed up for the PAKDD competition on Kaggle (ranking in the top 5%) and the 1st Alibaba Tianchi Big Data Competition in 2014, where we ranked 78th out of over 7,000 teams. Our third teammate was his classmate—she later became his girlfriend, and eventually, his wife. :)

• 2015 年参加了第二届阿里天池大数据竞赛——“阿里移动推荐算法”，队名 Wonder，排名 37/7186。

• In 2015, I participated in the 2nd Alibaba Tianchi Big Data Competition (Mobile Recommendation). Our team, "Wonder," ranked 37th out of 7,186 teams.

• 2019 年去了新疆环天山山脉自驾，在安集海大峡谷看过如水彩画般的河谷，在独库公路一日历经四季。风景极美，我以后还会再去。如果你还没去过，我强烈推荐你去看看。当然，还有那拉提草原、赛里木湖。

• In 2019, I went on a self-driving trip around the Tianshan Mountains in Xinjiang. I witnessed the watercolor-like riverbeds of the Anjihai Grand Canyon and experienced all four seasons in a single day along the Duku Highway. The scenery was breathtaking, and I definitely plan to return in the future. If you haven't been there, I highly recommend visiting—especially places like the Nalati Grassland and Sayram Lake.

• 2020 年春节前夕（新冠疫情爆发前夕），带爸妈去了新加坡和马来西亚。我们在马六甲度过了除夕，这也是我和爸妈第一次在国外过年，留下了非常美好的回忆。

• For the 2020 Lunar New Year (just before the COVID-19 outbreak), I took my parents on a trip to Singapore and Malaysia. We spent New Year's Eve in Malacca. It was the first time any of us had celebrated the New Year abroad, and it remains one of our most cherished memories.

• 2020 年国庆自驾川西大环线，走了 317、318 国道，熊猫大道，去了理塘、稻城亚丁。 深夜赶路去稻城时，在一处山路停留休息，我看到了 0 光污染下的清澈银河，抬头一瞬间还以为自己置身于太空。

• During the 2020 National Day holiday, I embarked on a grand loop road trip through Western Sichuan, traversing National Highways 317 and 318, as well as the Panda Avenue, visiting Litang and Daocheng Yading. While driving deep into the night toward Daocheng, I pulled over on a mountain pass to rest. Under zero light pollution, I was met with a breathtakingly clear view of the Milky Way. For a split second, looking up made me feel as though I were drifting in outer space.
