למידה מובנית עצבית מבוססת גרף ב- TFX

המדריך הבא מתאר להסדרת גרף מן הלמידה Structured העצבית המסגרת ומדגים זרימת עבודה מקצה לקצה עבור סיווג הסנטימנט צינור TFX.

סקירה כללית

ביקורות על סרטים מהחברה 'מסווגים זה כחיובי או שלילי באמצעות הטקסט של הביקורות. זוהי דוגמא של סיווג בינארי, כסוג חשוב החלים נרחב של בעיה בלמידה חישובית.

נדגים את השימוש בהסדרת גרפים במחברת זו על ידי בניית גרף מהקלט הנתון. המתכון הכללי לבניית מודל מוסדר גרף באמצעות מסגרת למידה מובנית עצבית (NSL) כאשר הקלט אינו מכיל גרף מפורש הוא כדלקמן:

  1. צור הטבעות עבור כל מדגם טקסט בקלט. ניתן לעשות זאת באמצעות מודלים מאומן מראש כגון word2vec , סיבוב , ברט וכו '
  2. בנו גרף על סמך הטמעות אלו על ידי שימוש במדד דמיון כגון מרחק 'L2', מרחק 'קוסינוס' וכו'. צמתים בגרף מתאימים לדגימות והקצוות בגרף תואמים לדמיון בין זוגות דגימות.
  3. צור נתוני אימון מהגרף המסונתז לעיל ותכונות לדוגמה. נתוני האימון שיתקבלו יכילו תכונות שכנות בנוסף לתכונות הצומת המקוריות.
  4. צור רשת עצבית כמודל בסיס באמצעות Estimators.
  5. עוטף את דגם הבסיס עם add_graph_regularization פונקצית המעטפת, אשר מסופקת על ידי מסגרת NSL, כדי ליצור מודל הערכת גרף חדש. מודל חדש זה יכלול אובדן הסדרת גרף כמונח ההסדרה ביעד ההכשרה שלו.
  6. אימון והערכת מודל האומד הגרף.

במדריך זה, אנו משלבים את זרימת העבודה שלעיל בצינור TFX תוך שימוש במספר רכיבי TFX מותאמים אישית וכן רכיב מאמן מותאם אישית עם גרף מוסדר.

להלן הסכימה של צינור ה-TFX שלנו. קופסאות כתומות מייצגות רכיבי TFX מהמדף וקופסאות ורודות מייצגות רכיבי TFX מותאמים אישית.

שדרוג פיפ

כדי להימנע משדרוג Pip במערכת בעת הפעלה מקומית, בדוק כדי לוודא שאנו פועלים ב-Colab. ניתן כמובן לשדרג מערכות מקומיות בנפרד.

try:
  import colab
  !pip install --upgrade pip
except:
  pass

התקן את החבילות הנדרשות

!pip install -q -U \
  tfx==1.2.0 \
  neural-structured-learning \
  tensorflow-hub \
  tensorflow-datasets

הפעלת מחדש את זמן הריצה?

אם אתה משתמש ב-Google Colab, בפעם הראשונה שאתה מפעיל את התא שלמעלה, עליך להפעיל מחדש את זמן הריצה (Runtime > Restart runtime...). זה בגלל האופן שבו קולאב טוען חבילות.

מערך נתונים של IMDB

הנתונים IMDB מכיל את הטקסט של 50,000 ביקורות סרטים מן במסד הנתונים הקולנועיים . אלה מחולקים ל-25,000 ביקורות לאימון ו-25,000 ביקורות לבדיקה. מגדיר ההדרכה ובחינות מאוזנים, כלומר הם מכילים מספר שווה של ביקורות חיוביות ושליליות. יתר על כן, יש 50,000 ביקורות סרטים נוספים ללא תווית.

הורד מערך נתונים IMDB מעובד מראש

הקוד הבא מוריד את מערך הנתונים של IMDB (או משתמש בעותק שמור אם הוא כבר הורד) באמצעות TFDS. כדי להאיץ את המחברת הזו, נשתמש רק ב-10,000 ביקורות מסומנות וב-10,000 ביקורות ללא תווית להדרכה, וב-10,000 ביקורות מבחנים לצורך הערכה.

רכיב SynthesizeGraph

בניית גרפים כוללת יצירת הטבעות עבור דוגמאות טקסט ולאחר מכן שימוש בפונקציית דמיון כדי להשוות בין ההטבעות.

נשתמש שיבוצים סיבוב pretrained ליצור שיבוצים של tf.train.Example פורמט עבור כל דגימה בקלט. אנו מאחסנים את השיבוצים וכתוצאה מכך TFRecord בפורמט יחד עם תעודת זהות המדגם. זה חשוב ויאפשר לנו להתאים הטמעות לדוגמה עם צמתים מתאימים בגרף מאוחר יותר.

ברגע שיש לנו את ההטבעות לדוגמה, נשתמש בהן כדי לבנות גרף דמיון, כלומר, צמתים בגרף זה יתאימו לדגימות וקצוות בגרף זה יתאימו לדמיון בין זוגות של צמתים.

למידה מובנית עצבית מספקת ספריית בניית גרפים לבניית גרף המבוסס על הטבעות לדוגמה. היא משתמשת דמיון קוסינוס כמדד דמיון להשוות שיבוצים וקצוות לבנות ביניהם. זה גם מאפשר לנו לציין סף דמיון, שניתן להשתמש בו כדי להשליך קצוות לא דומים מהגרף הסופי. בדוגמה הבאה, תוך שימוש ב-0.99 כסף הדמיון, בסופו של דבר נקבל גרף בעל 111,066 קצוות דו-כיווניים.

רכיב הטרנספורמציה

Transform טרנספורמציות נתונים מבצעים רכיב והנדסת תכונה. התוצאות כוללות גרף TensorFlow קלט המשמש הן במהלך האימון והן במהלך ההגשה כדי לעבד מראש את הנתונים לפני אימון או מסקנות. גרף זה הופך לחלק מה- SavedModel שהוא תוצאה של אימון מודלים. מכיוון שאותו גרף קלט משמש הן להדרכה והן להגשה, העיבוד המקדים תמיד יהיה זהה, ויש צורך לכתוב רק פעם אחת.

רכיב Transform דורש יותר קוד מאשר רכיבים רבים אחרים בגלל המורכבות השרירותית של הנדסת התכונות שאולי תזדקק לה עבור הנתונים ו/או המודל שאיתם אתה עובד. זה דורש שקבצי קוד יהיו זמינים שמגדירים את העיבוד הדרוש.

כל דוגמה תכלול את שלושת התכונות הבאות:

  1. id: הצומת מזהה של המדגם.
  2. text_xf: רשימה לא Int64 המכילה מזהה מילה.
  3. label_xf: סינגלטון Int64 זיהוי כיתת היעד של הסקירה: 0 = שלילי, 1 = חיובי.

  • transformed_examples מייצג את הנתונים הכשרה והערכה מעובד.

קח צצה אל transform_graph חפץ: זה מצביע לספרייה המכילה 3 תיקיות משנה:

train_uri = transform.outputs['transform_graph'].get()[0].uri
os.listdir(train_uri)
['transform_fn', 'transformed_metadata', 'metadata']

transform_fn בתיקייה מכילה הגרף המקדים בפועל. metadata בתיקייה מכילה בסכימה של נתון המקוריים. transformed_metadata בתיקייה מכילה סכימת נתון המעובדים.

עיין בכמה מהדוגמאות שעברו טרנספורמציה ובדוק שהן אכן מעובדות כמתוכנן.

מכיוון שיש לנו את התכונות לדוגמה ואת הגרף המסונתז, אנו יכולים ליצור את נתוני האימון המוגדלים עבור למידה מובנית עצבית. מסגרת ה-NSL מספקת ספרייה לשילוב הגרף והתכונות לדוגמה כדי לייצר את נתוני ההדרכה הסופיים להסדרת הגרפים. נתוני האימון שיתקבלו יכללו תכונות מדגמיות מקוריות וכן תכונות של שכניהם המקבילים.

במדריך זה, אנו רואים קצוות לא מכוונים ומשתמשים במקסימום 3 שכנים לכל דגימה כדי להגדיל את נתוני האימון עם שכנים גרפים.

#
# -   max_seq_length: This is the maximum number of words considered from each
#                     movie review in this example.
# -   vocab_size: This is the size of the vocabulary considered for this
#                 example.
# -   oov_size: This is the out-of-vocabulary size considered for this example.
# -   distance_type: This is the distance metric used to regularize the sample
#                    with its neighbors.
# -   graph_regularization_multiplier: This controls the relative weight of the
#                                      graph regularization term in the overall
#                                      loss function.
# -   num_neighbors: The number of neighbors used for graph regularization. This
#                    value has to be less than or equal to the `num_neighbors`
#                    argument used above in the GraphAugmentation component when
#                    invoking `nsl.tools.pack_nbrs`.
# -   num_fc_units: The number of units in the fully connected layer of the
#                   neural network.

  average pooling 1D layer, which reduces the dimensionality of its inputs from
  3D to 2D. This fixed-length output vector is piped through a fully-connected

# network can learn more complex representations. However, it makes the network
# more computationally expensive and may lead to learning unwanted
# patterns—patterns that improve performance on training data but not on the

הגשת דגם

הסדרת גרפים משפיעה רק על זרימת העבודה של האימון על ידי הוספת מונח רגוליזציה לפונקציית ההפסד. כתוצאה מכך, תהליכי העבודה של הערכת המודל והגשה נשארים ללא שינוי. זה מאותה הסיבה שאנחנו גם כבר הושמטנו רכיבי TFX במורד שבדרך כלל באים אחרי רכיב המאמן כמו המעריך, Pusher, וכו '

סיכום

הדגמנו את השימוש בהסדרת גרפים באמצעות המסגרת Neural Structured Learning (NSL) בצינור TFX גם כאשר הקלט אינו מכיל גרף מפורש. שקלנו את המשימה של סיווג סנטימנטים של ביקורות סרטים ב-IMDB שלגביה סינתזנו גרף דמיון המבוסס על הטבעות ביקורת. אנו ממליצים למשתמשים להתנסות נוספת על ידי שימוש בהטמעות שונות לבניית גרפים, הפרמטרים משתנים, שינוי כמות הפיקוח ועל ידי הגדרת ארכיטקטורות מודלים שונות.
