مكون هندسة الميزات في TensorFlow Extended (TFX)
يوفر هذا الكمبيوتر الدفتري سبيل المثال colab على سبيل المثال إلى حد ما أكثر تقدما لكيفية TensorFlow تحويل ( tf.Transform
) يمكن استخدامها لبيانات المعالجة المسبقة باستخدام بالضبط نفس رمز لكل من تدريب نموذج وخدمة الاستدلالات في الإنتاج.
TensorFlow Transform هي مكتبة للمعالجة المسبقة لبيانات الإدخال لـ TensorFlow ، بما في ذلك إنشاء الميزات التي تتطلب تمريرة كاملة عبر مجموعة بيانات التدريب. على سبيل المثال ، باستخدام TensorFlow Transform ، يمكنك:
- تطبيع قيمة الإدخال باستخدام المتوسط والانحراف المعياري
- تحويل السلاسل إلى أعداد صحيحة عن طريق توليد مفردات على كل قيم الإدخال
- قم بتحويل العوامات إلى أعداد صحيحة عن طريق تخصيصها لمجموعات ، بناءً على توزيع البيانات المرصود
يحتوي TensorFlow على دعم داخلي للمعالجة في مثال واحد أو مجموعة من الأمثلة. tf.Transform
تمتد هذه القدرات لدعم يمر الكاملة على بيانات التدريب بأكمله.
إخراج tf.Transform
يتم تصدير مثل رسم بياني TensorFlow التي يمكنك استخدامها للتدريب وخدمة. يمكن أن يؤدي استخدام نفس الرسم البياني لكل من التدريب والخدمة إلى منع الانحراف ، حيث يتم تطبيق نفس التحويلات في كلتا المرحلتين.
ما نفعله في هذا المثال
في هذا المثال سنكون تجهيز استخداما بيانات تحتوي على بيانات التعداد ، وتدريب نموذج للقيام التصنيف. على طول الطريق سوف يتم تحويل البيانات باستخدام tf.Transform
.
ترقية النقطة
لتجنب ترقية Pip في نظام عند التشغيل محليًا ، تحقق للتأكد من أننا نعمل في Colab. يمكن بالطبع ترقية الأنظمة المحلية بشكل منفصل.
try:
import colab
!pip install --upgrade pip
except:
pass
قم بتثبيت TensorFlow Transform
pip install tensorflow-transform
فحص بايثون ، والواردات ، والكرة الأرضية
أولاً ، سنتأكد من أننا نستخدم Python 3 ، ثم نمضي قدمًا ونثبت ونستورد الأشياء التي نحتاجها.

تجهيزها مع tf.Transform

أو SparseTensor
. هناك مجموعتان رئيسيتان من استدعاءات API التي تشكل عادةً قلب وظيفة المعالجة المسبقة:
- TensorFlow العمليات: أي وظيفة التي تقبل والعوائد التنسورات، وهو ما يعني عادة التقاط TensorFlow. تضيف هذه عمليات TensorFlow إلى الرسم البياني الذي يحول البيانات الأولية إلى بيانات محولة متجهًا لميزة واحدة في كل مرة. سيتم تشغيل هذه لكل مثال ، أثناء التدريب والخدمة.
- TensorFlow تحويل المحللون: أي من تحليل المقدمة من tf.Transform. تقبل المحللون أيضًا وتعيد الموترات ، ولكن على عكس عمليات TensorFlow ، فإنها تعمل مرة واحدة فقط ، أثناء التدريب ، وعادةً ما تقوم بتمرير كامل عبر مجموعة بيانات التدريب بأكملها. لأنها تخلق موتر الثوابت ، والتي تضاف إلى الرسم البياني الخاص بك. على سبيل المثال،
tft.min
يحسب الحد الأدنى من موتر على بيانات التدريب. tf يوفر Transform مجموعة ثابتة من أجهزة التحليل ، ولكن سيتم تمديدها في الإصدارات المستقبلية.

ماذا فعلنا
في هذا المثال استخدمنا tf.Transform
إلى المعالجة المسبقة لمجموعة بيانات بيانات التعداد، وتدريب نموذج مع البيانات تنظيفها وتحويلها. أنشأنا أيضًا وظيفة إدخال يمكننا استخدامها عندما ننشر نموذجنا المدرب في بيئة إنتاج لأداء الاستدلال. باستخدام نفس الرمز لكل من التدريب والاستدلال ، نتجنب أي مشكلات تتعلق بانحراف البيانات. على طول الطريقة التي تعلمنا بها إنشاء تحويل Apache Beam لإجراء التحويل الذي نحتاجه لتنظيف البيانات. ورأينا أيضا كيفية استخدام هذه البيانات تتحول لتدريب نموذج باستخدام tf.keras
أو tf.estimator
. هذا مجرد جزء صغير مما يمكن أن يفعله TensorFlow Transform! نحن نشجعك على الغوص في tf.Transform
واكتشاف ما يمكن القيام به بالنسبة لك.
