টিএফএক্স পাইপলাইন এবং টেনসরফ্লো মডেল বিশ্লেষণ ব্যবহার করে মডেল বিশ্লেষণ

এই নোটবুক-ভিত্তিক টিউটোরিয়ালে, আমরা একটি TFX পাইপলাইন তৈরি এবং চালাব যা একটি সাধারণ শ্রেণিবিন্যাস মডেল তৈরি করে এবং একাধিক রান জুড়ে এর কার্যক্ষমতা বিশ্লেষণ করে। এই নোটবুক TFX পাইপলাইন আমরা সালে নির্মিত উপর ভিত্তি করে তৈরি সরল TFX পাইপলাইন টিউটোরিয়াল । আপনি যদি এখনও সেই টিউটোরিয়ালটি না পড়ে থাকেন তবে এই নোটবুকটি নিয়ে এগিয়ে যাওয়ার আগে আপনার এটি পড়া উচিত।

আপনি যখন আপনার মডেলকে পরিবর্তন করবেন বা এটিকে একটি নতুন ডেটাসেট দিয়ে প্রশিক্ষিত করবেন, তখন আপনার মডেলটি উন্নত হয়েছে বা খারাপ হয়েছে কিনা তা পরীক্ষা করতে হবে। শুধু সঠিকতার মতো শীর্ষ-স্তরের মেট্রিক পরীক্ষা করা যথেষ্ট নাও হতে পারে। প্রতিটি প্রশিক্ষিত মডেল উৎপাদনে ঠেলে দেওয়ার আগে মূল্যায়ন করা উচিত।

আমরা একটি যোগ হবে Evaluator পূর্ববর্তী টিউটোরিয়ালে নির্মিত পাইপলাইন অংশ। মূল্যায়নকারী উপাদান আপনার মডেলগুলির জন্য গভীর বিশ্লেষণ করে এবং একটি বেসলাইনের সাথে নতুন মডেলের তুলনা করে তা নির্ধারণ করে যে তারা "যথেষ্ট ভাল"। এটি ব্যবহার বাস্তবায়িত হয় TensorFlow মডেল বিশ্লেষণ গ্রন্থাগার।

দয়া করে দেখুন TFX পাইপলাইন বুঝুন TFX বিভিন্ন ধারণা সম্পর্কে আরো জানতে।

সেট আপ করুন

সেট আপ প্রক্রিয়াটি আগের টিউটোরিয়ালের মতোই।

আমাদের প্রথমে TFX পাইথন প্যাকেজ ইনস্টল করতে হবে এবং ডেটাসেটটি ডাউনলোড করতে হবে যা আমরা আমাদের মডেলের জন্য ব্যবহার করব।

পিপ আপগ্রেড করুন

স্থানীয়ভাবে চালানোর সময় একটি সিস্টেমে পিপ আপগ্রেড করা এড়াতে, আমরা Colab-এ চালাচ্ছি কিনা তা নিশ্চিত করুন। স্থানীয় সিস্টেম অবশ্যই আলাদাভাবে আপগ্রেড করা যেতে পারে।

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

TFX ইনস্টল করুন

pip install -U tfx

আপনি কি রানটাইম রিস্টার্ট করেছেন?

আপনি যদি Google Colab ব্যবহার করেন, প্রথমবার যখন আপনি উপরের সেলটি চালান, তাহলে আপনাকে অবশ্যই উপরে "রিস্টার্ট RUNTIME" বোতামে ক্লিক করে বা "রানটাইম > রানটাইম রিস্টার্ট..." মেনু ব্যবহার করে রানটাইম রিস্টার্ট করতে হবে। Colab যেভাবে প্যাকেজগুলি লোড করে তার কারণেই এটি হয়েছে৷

TensorFlow এবং TFX সংস্করণ পরীক্ষা করুন।

ভেরিয়েবল সেট আপ করুন

একটি পাইপলাইন সংজ্ঞায়িত করতে ব্যবহৃত কিছু ভেরিয়েবল আছে। আপনি আপনার ইচ্ছা মত এই ভেরিয়েবল কাস্টমাইজ করতে পারেন. ডিফল্টরূপে পাইপলাইন থেকে সমস্ত আউটপুট বর্তমান ডিরেক্টরির অধীনে তৈরি করা হবে।

উদাহরণ ডেটা প্রস্তুত করুন

আমরা একই ব্যবহার করবে পামার পেঙ্গুইনদের ডেটা সেটটি

এই ডেটাসেটে চারটি সংখ্যাসূচক বৈশিষ্ট্য রয়েছে যা ইতিমধ্যেই পরিসীমা [0,1] থাকার জন্য স্বাভাবিক করা হয়েছে। আমরা একটি শ্রেণীবিভাগ মডেল যা অনুমান গড়ে তুলবে species পেঙ্গুইনদের করুন।

যেহেতু TFX ExampleGen একটি ডিরেক্টরি থেকে ইনপুট পড়ে, আমাদের একটি ডিরেক্টরি তৈরি করতে হবে এবং এতে ডেটাসেট কপি করতে হবে।

আমরা একটি যোগ হবে Evaluator পাইপলাইন আমরা তৈরি করতে কম্পোনেন্ট সরল TFX পাইপলাইন টিউটোরিয়াল

একটি Evaluator উপাদান একটি থেকে ইনপুট ডেটার প্রয়োজন ExampleGen উপাদান এবং একটি থেকে একটি মডেল Trainer উপাদান এবং tfma.EvalConfig অবজেক্ট। আমরা ঐচ্ছিকভাবে একটি বেসলাইন মডেল সরবরাহ করতে পারি যা নতুন প্রশিক্ষিত মডেলের সাথে মেট্রিক্স তুলনা করতে ব্যবহার করা যেতে পারে।

একটি evaluator আউটপুট নিদর্শন, দুই ধরণের সৃষ্টি ModelEvaluation এবং ModelBlessing । মডেল ইভালুয়েশনে বিস্তারিত মূল্যায়নের ফলাফল রয়েছে যা TFMA লাইব্রেরির সাহায্যে আরও তদন্ত এবং কল্পনা করা যেতে পারে। মডেলব্লেসিং-এ একটি বুলিয়ান ফলাফল রয়েছে যে মডেলটি প্রদত্ত মানদণ্ডে উত্তীর্ণ হয়েছে কিনা এবং একটি সংকেত হিসাবে পুশারের মতো পরবর্তী উপাদানগুলিতে ব্যবহার করা যেতে পারে।

  • কনফিগার করার জন্য স্লাইস
  • বৈধতা অন্তর্ভুক্ত করা হবে কিনা তা যাচাই করার জন্য মডেল বৈধতা থ্রেশহোল্ড

কারণ SparseCategoricalAccuracy ইতিমধ্যে অন্তর্ভুক্ত করা হয় model.compile() কল, এটা বিশ্লেষণ স্বয়ংক্রিয়ভাবে অন্তর্ভুক্ত করা হবে। তাই আমরা এখানে কোনো অতিরিক্ত মেট্রিক যোগ করি না। SparseCategoricalAccuracy সিদ্ধান্ত নিতে হবে মডেল যথেষ্ট, অত্যধিক ব্যবহার করা হবে।

আমরা সমগ্র ডেটাসেট এবং প্রতিটি পেঙ্গুইন প্রজাতির জন্য মেট্রিক্স গণনা করি। SlicingSpec নির্দিষ্ট করে আমরা কিভাবে ঘোষিত মেট্রিক্স সমষ্টি।

দুটি থ্রেশহোল্ড রয়েছে যা একটি নতুন মডেলের পাস করা উচিত, একটি হল 0.6 এর পরম থ্রেশহোল্ড এবং অন্যটি একটি আপেক্ষিক থ্রেশহোল্ড যা এটি বেসলাইন মডেলের চেয়ে বেশি হওয়া উচিত। আপনি যখন প্রথমবারের মত পাইপলাইন রান change_threshold উপেক্ষা করা হবে এবং শুধুমাত্র value_threshold চেক করা হবে। আপনি পাইপলাইন একাধিকবার চালানো, Resolver পূর্ববর্তী রান থেকে একটি মডেল পাবেন এবং এটি তুলনা জন্য একটি বেসলাইন মডেল হিসেবে ব্যবহার করা হবে।

তাহলে আশীর্বাদ ফল False , বিমানপোত করার মডেল ধাক্কা আপত্তি করবে serving_model_dir , কারণ মডেল যথেষ্ট উৎপাদনে ব্যবহার করা হয় না।

আপনি বিভিন্ন মূল্যায়ন কনফিগারেশনের সাথে আবার পাইপলাইন চালাতে পারেন। এমনকি যদি আপনি সঠিক একই কনফিগ এবং ডেটা সেটটি সঙ্গে পাইপলাইন চালানোর প্রশিক্ষণ মডেল সামান্য মডেল প্রশিক্ষণ যা হতে পারে অন্তর্বর্তী যদৃচ্ছতা কারণে বিভিন্ন হতে পারে NOT_BLESSED মডেল।
