學習經歷:  在大學修習時期有些課程不認真,以至於延宕畢業時間。迫使我更加珍惜努力學習,而找到編程 (programing) 之樂趣。放棄與克服之間我最終選擇後者,克服它。因此,透過不斷的練習,在資料結構 (Data Structure) 的正課上獲得84分,程式實作課總平均提高到90分。

Project process: 

分析&預處理:

使用 Kaggle UTKFace 約 23708 張 Face dataset -> 做 EDA 分析 (ex: sex, age, race) -> Data cleaning -> 將資料用Sklearn train_test_split 方法切割成 train: 80%, valid: 10%, test: 10% -> 將分好的資料寫成二進位格式轉成TFRecords 檔 (能夠在訓練時快速讀取大量資料) -> 讀取大量圖片檔案並轉成 numpy 格式,遇到 I/O 問題,使用 multiprocessing 跟容器減少讀取時間跟記憶體消耗 -> 解析 TFRecords 檔使用 tf.data pipeline (載入資料, 預先處理, cache, map, shuffle, prefetch) 

建模&訓練:

建立模型 (ex: VGG16, ResNet50, Xception, EfficientnetB5-7-L2, EfficientnetV2-m-l-xl) -> 使用 Transfer Learning 加 pre-trained model weights (ex: ImageNet) or Self-Supervised learning weights (ex: Noisy-student, ImageNet21K, ImageNet21K-ft1K) -> Fine-tuning -> 使用 Kaggle TPU/GPU 訓練 -> Evaluate Accuracy -> Plot predict curves -> Confusion Matrix -> Visualize prediction images -> F1 score
