    # Interview ## 專案清單 - 大一 C++ SDL 雙人對戰遊戲 - 大一 Micron 防疫機器人 - 大一 普物創意實驗競賽 - 大二 lost and found website - 大三 TEL 機器人擂台賽 - 大三 DLCV skull fracture - 大三 Embedded systems - 大三 VFX project - 大三 data science competition prediction with ECG - 大四 OS - 大四 motion prediction lab ### 專案細節 - Predict EF level with ECG - 碰到技術上最大的困難 - 在找出最適合的取 feature 方式的過程:我試過 Fourier transform, short-time Fourier transform, wavelet transform,最後很訝異的發現不做任何 transform 最好 - 有辦法改進的地方 - 太著重於資料前處理或是 data augmentation,沒有試過各種 model ## 故事清單 - DLCV skull fracture detection 趕死線 - **Situation**: 因為贊助廠商的 delay,在期末考週最後一個禮拜,老師才公佈了專案題目 - **Task**: 我們要做 skull fracture detection,要從頭設計、訓練一個機器學習模型,要能判斷出病人的頭顱有沒有骨裂,以及指出骨裂的位置。一開始,每個人對這個題目都有自己的想法,我們花了一天互相討論彼此的想法,但誰都說不準誰的方法比較好或比較差,我們確定的是,與其五個人各自努力,不如我們一起想辦法分工,一起產出一個最好的解法。 - **Action**: 我當時提議讓大家先各自做兩天,看最後結果如何,再決定我們最後要用哪一種方法。這段時間,我把我的模型訓練到一個還不錯的 baseline,但始終還是差了其中同學一點。我最後剩兩天時果斷決定放棄我的作法,努力幫當時 performance 最好的同學,我重寫了他的 dataloader,讓他比較有效率,也加上一些後處理 - **Results**: 最後我們有趕上那個死線,model 的表現也還不錯。雖然最後蠻可惜不是採用我的idea,但是換到了團隊的效率,我也很滿意這樣的安排,最後我還是有把我的 idea 寫進報告書裡給廠商參考 - OS 作業抄襲 - **Task**: 這是最近發生在我身上的事情,我在修一門 OS 的課,要寫一個類似 Linux 風格的作業系統,某次作業兩個人一組要實作一些 system call。 - **Situation**: 因為作業設計得非常困難,而且給學生的提示非常少,自由度非常大,我的組員決定偷偷參考網路上以前學生公開的 github,他以為這樣不會被發現。 - **Action**: 我們當時把作業分成兩部分,我在deadline前已經被一個 bug 卡了整整三天,身心都很疲憊。在 deadline 壓力之下,我隊友建議我參考一下別人的程式,趕快把作業完成。當下就認真的警告他我們不應該這麼做,而我最後比他多花了整整六天才把我的部分完成 - **Results**: 我們最後在那項作業拿到滿分,但是因為隊友抄襲的太明顯,還是被老師抓到,跟老師約談之後,隊友被送到懲戒委員會,那項作業拿了0分。老師告誡了我,以後只要在團隊裡發現任何不對勁的情形,都要第一時間當那個吹哨者。最後我沒事,但我也很慶幸在當時身心俱疲的情況下還是堅守自己的原則。 ## 我被問的問題 ## 我想問的問題 - 在公司工作有機會<mark>認識到別的部門</mark>的工程師嗎? - 譬如說我如果加入了 research 的部門,我有機會認識到負責寫網頁的工程師,或是把訓練好的 model 包裝成產品的人嗎 - 我有機會發 paper 嗎? - 現在正在進行的研究主題有哪些? - 我一加入的時候,會有<mark>明確的主題</mark>或是參與一個合作的團隊嗎? - 剛開始熟悉一個研究領域的時候,比較難第一時間就抓到這個領域有趣的題目,很容易陷入一直讀 paper 但沒有適合的研究題目的困境。
