COMPAS ชุดข้อมูล

COMPAS (เจ้าพนักงานผู้กระทำผิดการจัดการโปรไฟล์สำหรับทางเลือกการลงโทษ) เป็นชุดข้อมูลที่สาธารณะซึ่งมีประมาณ 18,000 คดีอาญาจากวอร์ดเคาน์ตี้ฟลอริดาระหว่างเดือนมกราคม 2013 ถึงเดือนธันวาคม 2014 ข้อมูลที่มีข้อมูลเกี่ยวกับจำเลยที่ไม่ซ้ำกัน 11,000 รวมทั้งประชากรประวัติอาชญากรรมและ คะแนนความเสี่ยงที่มีเจตนาเพื่อแสดงถึงโอกาสในการกระทำความผิดซ้ำของจำเลย (การกระทำผิดซ้ำ) ผู้พิพากษาและเจ้าหน้าที่ทัณฑ์บนได้ใช้แบบจำลองการเรียนรู้ของเครื่องที่ได้รับการฝึกอบรมเกี่ยวกับข้อมูลนี้เพื่อพิจารณาว่าจะให้ประกันตัวหรือไม่และจะให้ทัณฑ์บนหรือไม่

ในปี 2016 บทความตีพิมพ์ใน ProPublica พบว่ารูปแบบ COMPAS ถูกไม่ถูกต้องคาดการณ์ว่าจำเลยแอฟริกันอเมริกันจะ recidivate ในอัตราที่สูงกว่า counterparts สีขาวของพวกเขาในขณะที่คนผิวขาวจะไม่ recidivate ในอัตราที่สูงมาก สำหรับจำเลยคอเคเซียน ตัวแบบทำผิดพลาดไปในทิศทางตรงกันข้าม โดยคาดการณ์ที่ไม่ถูกต้องว่าพวกเขาจะไม่ก่ออาชญากรรมอีก ผู้เขียนได้แสดงต่อไปว่าอคติเหล่านี้น่าจะเกิดจากการกระจายข้อมูลที่ไม่เท่าเทียมกันระหว่างชาวแอฟริกัน-อเมริกันและจำเลยคอเคเซียน โดยเฉพาะป้ายจริงพื้นตัวอย่างเชิงลบ (จำเลยจะไม่ก่ออาชญากรรมอื่น) และตัวอย่างที่ดี (จำเลยจะก่ออาชญากรรมอื่น) มีสัดส่วนระหว่างสองเผ่าพันธุ์ ตั้งแต่ปี 2016 ชุด COMPAS ได้ปรากฏบ่อย ๆ ในความเป็นธรรม ML วรรณกรรม 1, 2, 3, กับนักวิจัยใช้มันเพื่อแสดงให้เห็นถึงเทคนิคในการระบุและที่แก้ไขความกังวลความเป็นธรรม นี้ กวดวิชาจาก FAT * การประชุม 2018 แสดงให้เห็นว่า COMPAS อย่างมากสามารถส่งผลกระทบต่อโอกาสของจำเลยในโลกแห่งความจริง

สิ่งสำคัญคือต้องสังเกตว่าการพัฒนาโมเดลแมชชีนเลิร์นนิงเพื่อทำนายการกักขังก่อนการพิจารณาคดีมีข้อพิจารณาด้านจริยธรรมที่สำคัญหลายประการ คุณสามารถเรียนรู้เพิ่มเติมเกี่ยวกับปัญหาเหล่านี้ในความร่วมมือใน AI“ รายงานเครื่องมือประเมินความเสี่ยงขั้นตอนในระบบยุติธรรมทางอาญาของสหรัฐ .” Partnership on AI เป็นองค์กรที่มีผู้มีส่วนได้ส่วนเสียหลายฝ่าย ซึ่ง Google เป็นสมาชิก ซึ่งสร้างแนวทางเกี่ยวกับ AI

เราใช้ชุดข้อมูล COMPAS เพื่อเป็นตัวอย่างในการระบุและแก้ไขข้อกังวลด้านความเป็นธรรมในข้อมูลเท่านั้น ชุดข้อมูลนี้เป็นมาตรฐานในเอกสารเกี่ยวกับความเป็นธรรมของอัลกอริทึม

เกี่ยวกับเครื่องมือในกรณีศึกษานี้

  • TensorFlow ขยาย (TFX) เป็นเครื่องที่ Google ผลิตระดับแพลตฟอร์มการเรียนรู้บนพื้นฐาน TensorFlow มีเฟรมเวิร์กการกำหนดค่าและไลบรารีที่ใช้ร่วมกันเพื่อรวมส่วนประกอบทั่วไปที่จำเป็นในการกำหนด เปิดใช้ และตรวจสอบระบบการเรียนรู้ของเครื่อง

  • TensorFlow รูปแบบการวิเคราะห์ เป็นห้องสมุดสำหรับการประเมินโมเดลการเรียนรู้เครื่อง ผู้ใช้สามารถประเมินแบบจำลองของตนกับข้อมูลจำนวนมากในลักษณะแบบกระจาย และดูตัวชี้วัดในส่วนต่างๆ ภายในสมุดบันทึก

  • ความเป็นธรรมชี้วัด เป็นชุดของเครื่องมือที่สร้างบน TensorFlow รูปแบบการวิเคราะห์ที่ช่วยให้การประเมินผลปกติของตัวชี้วัดความเป็นธรรมในระบบท่อส่งผลิตภัณฑ์

  • ML Metadata เป็นห้องสมุดสำหรับการบันทึกและเรียกเชื้อสายและเมตาดาต้าของสิ่งประดิษฐ์ ML เช่นโมเดลชุดข้อมูลและเมตริก ภายในข้อมูลเมตาของ TFX ML จะช่วยให้เราเข้าใจสิ่งประดิษฐ์ที่สร้างขึ้นในไปป์ไลน์ ซึ่งเป็นหน่วยข้อมูลที่ส่งผ่านระหว่างส่วนประกอบ TFX

  • TensorFlow การตรวจสอบข้อมูล เป็นห้องสมุดในการวิเคราะห์ข้อมูลของคุณและตรวจสอบข้อผิดพลาดที่อาจมีผลต่อการฝึกอบรมรุ่นหรือการให้บริการ

ภาพรวมกรณีศึกษา

ในช่วงเวลาของกรณีศึกษานี้ เราจะให้คำจำกัดความ "ข้อกังวลด้านความเป็นธรรม" ว่าเป็นอคติภายในแบบจำลองที่ส่งผลกระทบในทางลบต่อส่วนย่อยภายในข้อมูลของเรา โดยเฉพาะอย่างยิ่ง เรากำลังพยายามจำกัดการทำนายการกระทำผิดซ้ำที่อาจมีความลำเอียงต่อเชื้อชาติ

การดำเนินการของกรณีศึกษาจะดำเนินการดังนี้:

  1. ดาวน์โหลดข้อมูล ประมวลผลล่วงหน้า และสำรวจชุดข้อมูลเริ่มต้น
  2. สร้างไปป์ไลน์ TFX ด้วยชุดข้อมูล COMPAS โดยใช้ตัวแยกประเภทไบนารี Keras
  3. ดำเนินการผลลัพธ์ของเราผ่านการวิเคราะห์แบบจำลอง TensorFlow การตรวจสอบข้อมูล TensorFlow และโหลดตัวบ่งชี้ความเป็นธรรมเพื่อสำรวจข้อกังวลด้านความเป็นธรรมที่อาจเกิดขึ้นภายในแบบจำลองของเรา
  4. ใช้ ML Metadata เพื่อติดตามสิ่งประดิษฐ์ทั้งหมดสำหรับโมเดลที่เราฝึกด้วย TFX
  5. ให้น้ำหนักชุดข้อมูล COMPAS เริ่มต้นสำหรับโมเดลที่สองของเราเพื่อพิจารณาการกระจายที่ไม่สม่ำเสมอระหว่างการกระทำผิดซ้ำและการแข่งขัน
  6. ตรวจสอบการเปลี่ยนแปลงประสิทธิภาพภายในชุดข้อมูลใหม่
  7. ตรวจสอบการเปลี่ยนแปลงที่สำคัญภายในไปป์ไลน์ TFX ของเราด้วย ML Metadata เพื่อทำความเข้าใจว่ามีการเปลี่ยนแปลงใดบ้างระหว่างสองโมเดล

การสร้างท่อส่ง TFX


มีหลาย TFX ท่อส่งส่วนประกอบ ที่สามารถนำมาใช้สำหรับการผลิตแบบ แต่สำหรับวัตถุประสงค์กรณีนี้การศึกษาจะมุ่งเน้นการใช้เพียงด้านล่างส่วนประกอบ:

  • ExampleGen อ่านชุดข้อมูลของเรา
  • StatisticsGen การคำนวณสถิติของชุดข้อมูลของเรา
  • SchemaGen เพื่อสร้างสคีข้อมูล
  • แปลงสำหรับวิศวกรรมคุณลักษณะ
  • เทรนเนอร์ที่จะเรียกใช้รูปแบบการเรียนรู้ที่เครื่องของเรา

สร้าง InteractiveContext

เมื่อต้องการเรียกใช้ TFX ภายในโน้ตบุ๊คอันดับแรกเราจะต้องสร้าง InteractiveContext จะใช้องค์ประกอบโต้ตอบ

InteractiveContext จะใช้ไดเรกทอรีชั่วคราวกับฐานข้อมูลเช่น ML Metadata ชั่วคราว ที่จะใช้รากท่อของคุณเองหรือฐานข้อมูลคุณสมบัติที่ไม่จำเป็น pipeline_root และ metadata_connection_config อาจจะส่งผ่านไปยัง InteractiveContext

context = InteractiveContext()

TFX ExampleGen ส่วนประกอบ

# The ExampleGen TFX Pipeline component ingests data into TFX pipelines.
# It consumes external files/services to generate Examples which will be read by
# other TFX components. It also provides consistent and configurable partition,
# and shuffles the dataset for ML best practice.

TFX StatisticsGen Component

# The StatisticsGen TFX pipeline component generates features statistics over
# both training and serving data, which can be used by other pipeline
# components. StatisticsGen uses Beam to scale to large datasets.

statistics_gen = StatisticsGen(examples=example_gen.outputs['examples'])
context.run(statistics_gen)

ส่วนประกอบ TFX SchemaGen

# Some TFX components use a description of your input data called a schema. The
# schema is an instance of schema.proto. It can specify data types for feature
# values, whether a feature has to be present in all examples, allowed value
# ranges, and other properties. A SchemaGen pipeline component will
# automatically generate a schema by inferring types, categories, and ranges
# from the training data.

ส่วนประกอบการแปลง TFX

Transform ดำเนินองค์ประกอบข้อมูลแปลงวิศวกรรมและคุณลักษณะ ผลลัพธ์รวมถึงกราฟอินพุต TensorFlow ซึ่งใช้ระหว่างการฝึกและการเสิร์ฟเพื่อประมวลผลข้อมูลล่วงหน้าก่อนการฝึกหรือการอนุมาน กราฟนี้จะกลายเป็นส่วนหนึ่งของ SavedModel ซึ่งเป็นผลมาจากการฝึกโมเดล เนื่องจากใช้กราฟอินพุตเดียวกันสำหรับการฝึกและการเสิร์ฟ การประมวลผลล่วงหน้าจะเหมือนเดิมเสมอ และจำเป็นต้องเขียนเพียงครั้งเดียว

คอมโพเนนต์การแปลงต้องใช้โค้ดมากกว่าส่วนประกอบอื่นๆ เนื่องจากความซับซ้อนตามอำเภอใจของวิศวกรรมคุณลักษณะที่คุณอาจต้องการสำหรับข้อมูลและ/หรือโมเดลที่คุณกำลังทำงานด้วย

กำหนดค่าคงที่บางและฟังก์ชั่นสำหรับทั้ง Transform องค์ประกอบและ Trainer ส่วนประกอบ กําหนดไว้ในโมดูลหลามในกรณีนี้บันทึกไว้ในฮาร์ดดิสก์โดยใช้ %%writefile คำสั่งมายากลตั้งแต่ที่คุณกำลังทำงานอยู่ในโน๊ตบุ๊ค

การเปลี่ยนแปลงที่เราจะดำเนินการในกรณีศึกษานี้มีดังนี้:

  • สำหรับค่าสตริง เราจะสร้างคำศัพท์ที่จับคู่กับจำนวนเต็มผ่าน tft.compute_and_apply_vocabulary
  • สำหรับค่าจำนวนเต็ม เราจะกำหนดมาตรฐานของค่าเฉลี่ยคอลัมน์ 0 และความแปรปรวน 1 ผ่าน tft.scale_to_z_score
  • ลบค่าแถวว่างและแทนที่ด้วยสตริงว่างหรือ 0 ขึ้นอยู่กับประเภทของคุณลักษณะ
  • ผนวก '_xf' ต่อท้ายชื่อคอลัมน์เพื่อแสดงคุณลักษณะที่ได้รับการประมวลผลใน Transform Component

ตอนนี้ขอกำหนดโมดูลที่มี preprocessing_fn() ฟังก์ชั่นที่เราจะผ่านไป Transform องค์ประกอบ:

การวิเคราะห์แบบจำลอง TensorFlow

ขณะนี้ โมเดลของเราได้รับการพัฒนาและฝึกฝนภายใน TFX แล้ว เราสามารถใช้ส่วนประกอบเพิ่มเติมหลายอย่างภายใน TFX exosystem เพื่อทำความเข้าใจประสิทธิภาพของโมเดลของเราในรายละเอียดเพิ่มเติมเล็กน้อย การดูเมตริกต่างๆ ทำให้เราได้ภาพที่ดีขึ้นว่าโมเดลโดยรวมทำงานอย่างไรสำหรับชิ้นส่วนต่างๆ ภายในโมเดลของเรา เพื่อให้แน่ใจว่าโมเดลของเราไม่ได้มีประสิทธิภาพต่ำกว่ากลุ่มย่อยใดๆ

อันดับแรก เราจะตรวจสอบ TensorFlow Model Analysis ซึ่งเป็นไลบรารีสำหรับประเมินโมเดล TensorFlow อนุญาตให้ผู้ใช้ประเมินแบบจำลองของตนกับข้อมูลจำนวนมากในลักษณะแบบกระจาย โดยใช้ตัวชี้วัดเดียวกันที่กำหนดไว้ในผู้ฝึกสอน เมตริกเหล่านี้สามารถคำนวณผ่านส่วนต่างๆ ของข้อมูลและแสดงเป็นภาพในโน้ตบุ๊ก

สำหรับรายชื่อของตัวชี้วัดที่เป็นไปได้ที่สามารถเพิ่มเข้าไปใน TensorFlow รุ่นวิเคราะห์ดู ที่นี่

# Uses TensorFlow Model Analysis to compute a evaluation statistics over
# features of a model.
model_analyzer = Evaluator(
    examples=example_gen.outputs['examples'],
    model=trainer.outputs['model'],

    eval_config = text_format.Parse("""

ตัวบ่งชี้ความเป็นธรรมจะช่วยให้เราเจาะลึกเพื่อดูประสิทธิภาพของส่วนต่างๆ และออกแบบมาเพื่อสนับสนุนทีมในการประเมินและปรับปรุงแบบจำลองสำหรับข้อกังวลด้านความเป็นธรรม ช่วยให้คำนวณตัวแยกประเภทไบนารีและมัลติคลาสได้ง่าย และจะช่วยให้คุณประเมินกรณีการใช้งานทุกขนาด

เราจะโหลดตัวบ่งชี้ความเป็นธรรมลงในสมุดบันทึกนี้และวิเคราะห์ผลลัพธ์และดูผลลัพธ์ หลังจากที่คุณได้ลองใช้ตัวบ่งชี้ความเป็นธรรมมาสักระยะแล้ว ให้ตรวจสอบแท็บอัตราการบวกเท็จและอัตราการติดลบเท็จในเครื่องมือ ในกรณีศึกษานี้เรากำลังกังวลกับการพยายามที่จะลดจำนวนของการคาดการณ์ที่ผิดพลาดของการกระทำผิดซ้ำที่สอดคล้องกับ เท็จอัตราบวก

ข้อผิดพลาดประเภท I และ Type II

ภายในเครื่องมือตัวบ่งชี้ความเป็นธรรม คุณจะเห็นตัวเลือกดรอปดาวน์สองตัวเลือก:

  1. A "พื้นฐาน" ตัวเลือกที่ถูกกำหนดโดย column_for_slicing
  2. A "เกณฑ์" ตัวเลือกที่ถูกกำหนดโดย fairness_indicator_thresholds

“เส้นฐาน” คือส่วนข้อมูลที่คุณต้องการเปรียบเทียบส่วนอื่นๆ ทั้งหมด โดยทั่วไป จะแสดงโดยส่วนรวม แต่ก็สามารถเป็นหนึ่งในส่วนที่เฉพาะเจาะจงได้เช่นกัน

"เกณฑ์" เป็นค่าที่ตั้งไว้ในแบบจำลองการจัดประเภทไบนารีที่กำหนดเพื่อระบุว่าควรวางการคาดการณ์ไว้ที่ใด เมื่อตั้งค่าขีดจำกัด มีสองสิ่งที่คุณควรจำไว้

  1. ความแม่นยำ: อะไรคือข้อเสียหากการคาดการณ์ของคุณส่งผลให้เกิดข้อผิดพลาดประเภทที่ 1 ในกรณีศึกษานี้เกณฑ์ที่สูงขึ้นจะหมายถึงเรากำลังคาดการณ์จำเลยมากขึ้นจะก่ออาชญากรรมอีกครั้งเมื่อพวกเขาทำจริงไม่ได้
  2. จำได้ว่า: อะไรคือข้อเสียของข้อผิดพลาด Type II? ในกรณีศึกษานี้เกณฑ์ที่สูงขึ้นจะหมายถึงเรากำลังคาดการณ์จำเลยมากขึ้นจะไม่ได้ก่ออาชญากรรมอีกครั้งเมื่อพวกเขาทำจริง

เราจะกำหนดเกณฑ์ตามอำเภอใจที่ 0.75 และเราจะเน้นที่ตัวชี้วัดความเป็นธรรมสำหรับจำเลยชาวแอฟริกัน-อเมริกันและคอเคเซียนเท่านั้น โดยพิจารณาจากขนาดตัวอย่างเล็กๆ สำหรับเชื้อชาติอื่นๆ ซึ่งไม่ใหญ่พอที่จะสรุปผลที่มีนัยสำคัญทางสถิติ

อัตราด้านล่างอาจแตกต่างกันเล็กน้อยขึ้นอยู่กับวิธีการสับข้อมูลในช่วงเริ่มต้นของกรณีศึกษานี้ แต่ให้ดูที่ความแตกต่างระหว่างข้อมูลระหว่างจำเลยแอฟริกัน-อเมริกันและคอเคเซียน ในระดับที่ต่ำกว่า แบบจำลองของเรามีแนวโน้มที่จะคาดการณ์ว่าผู้ถูกปกป้องของคอเคเซียนจะก่ออาชญากรรมครั้งที่สอง เมื่อเทียบกับชาวแอฟริกัน-อเมริกันที่ได้รับการปกป้อง อย่างไรก็ตาม การคาดคะเนนี้จะกลับด้านเมื่อเราเพิ่มเกณฑ์ของเรา

  • อัตราบวกเท็จ @ 0.75
    • แอฟริกันอเมริกัน: ~ 30%
      • AUC: 0.71
      • ความแม่นยำไบนารี: 0.67
    • คนผิวขาว: ~ 8%
      • AUC: 0.71
      • AUC: 0.67

ML Metadata

สำหรับกรณีศึกษานี้ เราจะแสดงรายการสิ่งประดิษฐ์ทั้งหมดที่เราพัฒนาก่อนหน้านี้ภายในกรณีศึกษานี้ โดยการวนรอบสิ่งประดิษฐ์ การดำเนินการ และบริบท เราจะมีมุมมองในระดับสูงของโมเดล TFX ของเราเพื่อเจาะลึกว่าปัญหาที่อาจเกิดขึ้นมาจากที่ใด สิ่งนี้จะให้ภาพรวมพื้นฐานว่าแบบจำลองของเราได้รับการพัฒนาอย่างไรและส่วนประกอบ TFX ใดที่ช่วยในการพัฒนาแบบจำลองเริ่มต้นของเรา

เราจะเริ่มต้นด้วยการจัดวางสิ่งประดิษฐ์ระดับสูง การดำเนินการ และประเภทบริบทในแบบจำลองของเราก่อน

สำหรับอาร์ติแฟกต์ การดำเนินการ และประเภทบริบทแต่ละประเภทข้างต้น เราสามารถใช้ ML Metadata เพื่อเจาะลึกแอตทริบิวต์และวิธีพัฒนาไปป์ไลน์ ML แต่ละส่วนของเรา

เราจะเริ่มต้นด้วยการดำน้ำใน StatisticsGen เพื่อตรวจสอบข้อมูลพื้นฐานที่เราเริ่มป้อนเข้ารูปแบบ ด้วยการรู้จักสิ่งประดิษฐ์ภายในแบบจำลองของเรา เราจึงสามารถใช้ ML Metadata และ TensorFlow Data Validation เพื่อมองย้อนกลับและไปข้างหน้าภายในโมเดลเพื่อระบุว่าปัญหาที่อาจเกิดขึ้นมาจากที่ใด

ปรับปรุงข้อกังวลด้านความเป็นธรรมด้วยการให้น้ำหนักตัวแบบ

มีหลายวิธีที่เราสามารถแก้ไขข้อกังวลด้านความเป็นธรรมภายในแบบจำลองได้ การจัดการกับข้อมูลที่สังเกต / ป้ายดำเนินการข้อ จำกัด ของความเป็นธรรมหรือการกำจัดอคติโดยกูมีเทคนิคบางอย่าง 1 ที่มีการใช้ความกังวลเกี่ยวกับการแก้ไขปัญหาความเป็นธรรม ในกรณีศึกษานี้ เราจะทำการชั่งน้ำหนักโมเดลใหม่โดยใช้ฟังก์ชันการสูญเสียที่กำหนดเองใน Keras

หลังจากฝึกผลลัพธ์ของเราใหม่ด้วยโมเดลแบบถ่วงน้ำหนักแล้ว เราก็สามารถดูตัววัดความเป็นธรรมได้อีกครั้งเพื่อวัดการปรับปรุงใดๆ ในตัวแบบ อย่างไรก็ตาม ในครั้งนี้ เราจะใช้คุณลักษณะการเปรียบเทียบแบบจำลองภายในตัวบ่งชี้ความเป็นธรรมเพื่อดูความแตกต่างระหว่างแบบจำลองที่ถ่วงน้ำหนักและไม่ถ่วงน้ำหนัก แม้ว่าเราจะยังเห็นข้อกังวลเรื่องความเป็นธรรมอยู่บ้างกับแบบจำลองที่ถ่วงน้ำหนัก แต่ความคลาดเคลื่อนนั้นเด่นชัดน้อยกว่ามาก

อย่างไรก็ตาม ข้อเสียคือ AUC และความแม่นยำแบบไบนารีของเราลดลงเช่นกันหลังจากการให้น้ำหนักแบบจำลอง

  • อัตราบวกเท็จ @ 0.75
    • แอฟริกันอเมริกัน: ~ 1%
      • AUC: 0.47
      • ความแม่นยำไบนารี: 0.59
    • คนผิวขาว: ~ 0%
      • AUC: 0.47
      • ความแม่นยำไบนารี: 0.58

ตรวจสอบข้อมูลของการวิ่งครั้งที่สอง

สุดท้าย เราสามารถดูข้อมูลด้วย TensorFlow Data Validation และซ้อนทับการเปลี่ยนแปลงข้อมูลระหว่างสองโมเดล และเพิ่มหมายเหตุเพิ่มเติมใน ML Metadata ซึ่งบ่งชี้ว่าโมเดลนี้ได้ปรับปรุงข้อกังวลด้านความเป็นธรรม

บทสรุป

ในกรณีศึกษานี้ เราได้พัฒนาตัวแยกประเภท Keras ภายในไปป์ไลน์ TFX พร้อมชุดข้อมูล COMPAS เพื่อตรวจสอบข้อกังวลด้านความเป็นธรรมภายในชุดข้อมูล หลังจากเริ่มพัฒนา TFX ในขั้นต้น ความกังวลเรื่องความเป็นธรรมก็ไม่ปรากฏให้เห็นในทันที จนกว่าจะตรวจสอบส่วนต่างๆ ภายในแบบจำลองของเราโดยใช้คุณลักษณะที่ละเอียดอ่อนของเรา -- ในกรณีของเรา หลังจากระบุปัญหาแล้ว เราสามารถติดตามแหล่งที่มาของปัญหาความเป็นธรรมด้วย TensorFlow DataValidation เพื่อระบุวิธีการบรรเทาข้อกังวลด้านความเป็นธรรมผ่านการให้น้ำหนักแบบจำลองขณะติดตามและทำหมายเหตุประกอบการเปลี่ยนแปลงผ่าน ML Metadata แม้ว่าเราจะไม่สามารถแก้ไขข้อกังวลด้านความเป็นธรรมทั้งหมดภายในชุดข้อมูลได้อย่างสมบูรณ์ แต่การเพิ่มหมายเหตุสำหรับนักพัฒนาในอนาคตที่จะปฏิบัติตามจะช่วยให้ผู้อื่นเข้าใจและปัญหาที่เราเผชิญขณะพัฒนาโมเดลนี้

สุดท้ายนี้ เป็นสิ่งสำคัญที่จะต้องทราบว่ากรณีศึกษานี้ไม่ได้แก้ไขปัญหาความเป็นธรรมที่มีอยู่ในชุดข้อมูล COMPAS ด้วยการปรับปรุงข้อกังวลด้านความเป็นธรรมในแบบจำลอง เรายังลด AUC และความแม่นยำในประสิทธิภาพของแบบจำลองด้วย อย่างไรก็ตาม สิ่งที่เราสามารถทำได้คือสร้างแบบจำลองที่แสดงข้อกังวลด้านความเป็นธรรมและติดตามว่าปัญหาอาจมาจากที่ใดโดยการติดตามหรือสายเลือดของแบบจำลองในขณะเดียวกันก็ใส่คำอธิบายประกอบเกี่ยวกับข้อกังวลของแบบจำลองภายในข้อมูลเมตา
