Máy tính xách tay ví dụ colab này cung cấp một ví dụ hơi tiên tiến hơn về cách TensorFlow transform ( tf.Transform ) có thể được sử dụng để dữ liệu preprocess sử dụng chính xác cùng mã cho cả đào tạo một mô hình và phục vụ suy luận trong sản xuất.
TensorFlow Transform là một thư viện để xử lý trước dữ liệu đầu vào cho TensorFlow, bao gồm việc tạo các tính năng yêu cầu chuyển toàn bộ tập dữ liệu đào tạo. Ví dụ: sử dụng TensorFlow Transform, bạn có thể:
- Chuẩn hóa giá trị đầu vào bằng cách sử dụng giá trị trung bình và độ lệch chuẩn
- Chuyển đổi chuỗi thành số nguyên bằng cách tạo từ vựng trên tất cả các giá trị đầu vào
- Chuyển đổi float thành số nguyên bằng cách gán chúng vào nhóm, dựa trên phân phối dữ liệu quan sát được
TensorFlow có hỗ trợ tích hợp cho các thao tác trên một ví dụ hoặc một loạt ví dụ. tf.Transform mở rộng những khả năng để hỗ trợ đèo đầy đủ trên toàn bộ tập dữ liệu huấn luyện.
Kết quả của tf.Transform được xuất ra dưới dạng một đồ thị TensorFlow mà bạn có thể sử dụng cho cả đào tạo và phục vụ. Việc sử dụng cùng một biểu đồ cho cả quá trình luyện tập và phục vụ có thể ngăn chặn sự sai lệch, vì các phép biến đổi giống nhau được áp dụng trong cả hai giai đoạn.
Chúng tôi đang làm gì trong ví dụ này
Trong ví dụ này chúng tôi sẽ xử lý một sử dụng rộng rãi bộ dữ liệu chứa dữ liệu điều tra dân số , và đào tạo một mô hình để làm phân. Trên đường đi chúng tôi sẽ chuyển đổi dữ liệu sử dụng tf.Transform .
Nâng cấp Pip
Để tránh nâng cấp Pip trong hệ thống khi chạy cục bộ, hãy kiểm tra để đảm bảo rằng chúng tôi đang chạy trong Colab. Hệ thống cục bộ tất nhiên có thể được nâng cấp riêng.
try:
import colab
!pip install --upgrade pip
except:
pass
Cài đặt TensorFlow Transform
pip install tensorflow-transform
Kiểm tra Python, nhập khẩu và toàn cầu
Trước tiên, chúng tôi sẽ đảm bảo rằng chúng tôi đang sử dụng Python 3, sau đó tiếp tục cài đặt và nhập những thứ chúng tôi cần.

Tiền xử lý với tf.Transform
Tạo một tf.Transform preprocessing_fn
Chức năng tiền xử lý là khái niệm quan trọng nhất của tf.Transform. Chức năng tiền xử lý là nơi mà việc chuyển đổi tập dữ liệu thực sự xảy ra. Nó chấp nhận và trả về một cuốn từ điển của tensors, nơi một tensor nghĩa một Tensor hoặc SparseTensor . Có hai nhóm lệnh gọi API chính thường tạo thành trung tâm của một hàm tiền xử lý:
- TensorFlow Ops: Bất kỳ chức năng chấp nhận và trả tensors, mà thường có nghĩa là ops TensorFlow. Các thao tác này thêm các hoạt động TensorFlow vào biểu đồ để biến đổi dữ liệu thô thành dữ liệu đã biến đổi, từng vectơ đặc trưng tại một thời điểm. Chúng sẽ chạy cho mọi ví dụ, trong cả quá trình đào tạo và phục vụ.
- TensorFlow Biến đổi phân tích: Bất kỳ của các phân tích được cung cấp bởi tf.Transform. Các trình phân tích cũng chấp nhận và trả về các tensor, nhưng không giống như các hoạt động của TensorFlow, chúng chỉ chạy một lần trong quá trình đào tạo và thường thực hiện chuyển toàn bộ qua toàn bộ tập dữ liệu đào tạo. Họ tạo tensor hằng , được thêm vào đồ thị của bạn. Ví dụ,
tft.mintính tối thiểu của một tensor trong tập dữ liệu huấn luyện. tf.Transform cung cấp một bộ phân tích cố định, nhưng bộ này sẽ được mở rộng trong các phiên bản tương lai.
def preprocessing_fn(inputs):
"""Preprocess input columns into transformed columns."""

Chuyển đổi dữ liệu
Bây giờ chúng tôi đã sẵn sàng để bắt đầu chuyển đổi dữ liệu của mình trong một đường dẫn Apache Beam.
- Đọc dữ liệu bằng trình đọc CSV
- Biến đổi nó bằng cách sử dụng một đường ống tiền xử lý để chia tỷ lệ dữ liệu số và chuyển đổi dữ liệu phân loại từ chuỗi thành chỉ số giá trị int64, bằng cách tạo từ vựng cho từng danh mục
- Viết ra kết quả như một

Sử dụng dữ liệu đã xử lý trước của chúng tôi để đào tạo mô hình bằng tf.keras
Để hiển thị như thế nào tf.Transform cho phép chúng ta sử dụng cùng mã cho cả đào tạo và phục vụ, và do đó ngăn ngừa nghiêng, chúng ta sẽ đào tạo một mô hình. Để đào tạo mô hình của chúng tôi và chuẩn bị mô hình được đào tạo của chúng tôi để sản xuất, chúng tôi cần tạo các hàm đầu vào. Sự khác biệt chính giữa chức năng đầu vào đào tạo của chúng tôi và chức năng đầu vào phục vụ của chúng tôi là dữ liệu đào tạo chứa các nhãn, còn dữ liệu sản xuất thì không. Các đối số và trả về cũng hơi khác nhau.

Những gì chúng ta đã làm
Trong ví dụ này chúng tôi sử dụng tf.Transform để preprocess một tập dữ liệu của dữ liệu điều tra dân số, và đào tạo một mô hình với dữ liệu làm sạch và chuyển đổi. Chúng tôi cũng đã tạo một hàm đầu vào mà chúng tôi có thể sử dụng khi triển khai mô hình được đào tạo của mình trong môi trường sản xuất để thực hiện suy luận. Bằng cách sử dụng cùng một mã cho cả đào tạo và suy luận, chúng tôi tránh được bất kỳ vấn đề nào với sự sai lệch dữ liệu. Trong quá trình thực hiện, chúng tôi đã tìm hiểu về cách tạo biến đổi Apache Beam để thực hiện chuyển đổi mà chúng tôi cần để làm sạch dữ liệu. Chúng tôi cũng thấy làm thế nào để sử dụng dữ liệu chuyển đổi này để đào tạo một mô hình sử dụng một trong hai tf.keras hoặc tf.estimator . Đây chỉ là một phần nhỏ về những gì mà TensorFlow Transform có thể làm được! Chúng tôi khuyến khích bạn bổ nhào vào tf.Transform và khám phá những gì nó có thể làm cho bạn.
