pyrecdp 1.0.1b20230310

A data processing bundle for spark based recommender system operations

RecDP v2.0

INTRODUCTION

Problem Statement

Data Preparation is an essential step to build AI pipelines

• key data preparation capabilities: data connector, cleaning, sampling, joining, profiling, feature engineering, low-code/no-code UI, lineage etc.
• exploration of optimal Data preparation consumes majority of Data Science time

Solution with RecDP v2.0

• Auto pipeline
  • only 3 lines of codes required
• Pipeline Generator
  • Data Profiling:
    • Auto anomalies detection
    • Auto missing value impute
    • Profiling Visualizzation
  • Feature Wrangling:
    • feature transformation(datetime, geo_info, text_nlp, url, etc.)
    • multiple data auto joining
    • feature cross(aggregation transformation - sum, avg, count, etc.)
  • export pipeline as JSON file, can be import to other data platform
• Pipeline Runner:
  • spark engine: convert pipeline to spark codes to run
  • pandas engine: convert pipeline to pandas codes to run
  • sql engine: convert pipeline to sql
• DataLoader:
  • parquet, csv, json, database
• FeatureWriter - ML/DL connector:
  • Data Lineage
  • Feature Store
  • numpy, csv, parquet, dgl / pyG graph

This solution is intended for

citizen data scientists, enterprise users, independent software vendor and partial of cloud service provider.

Getting Start

setup with pip

git clone --single-branch --branch RecDP_v2.0 https://github.com/intel-innersource/frameworks.bigdata.AIDK.git
cd frameworks.bigdata.AIDK/RecDP
# install dependencies
apt-get update -y &&  DEBIAN_FRONTEND=noninteractive apt-get install -y python3 python3-pip python-is-python3 graphviz
DEBIAN_FRONTEND=noninteractive apt-get install -y openjdk-8-jre
# install recdp
python setup.py sdist
pip install dist/pyrecdp-1.0.1.tar.gz

sh start-jupyter.sh
# open browser with http://hostname:8888

run

from pyrecdp.autofe import FeatureWrangler

pipeline = FeatureWrangler(dataset=train_data, label="fare_amount")
pipeline.plot()

Quick Example

• nyc taxi fare - geographic, datetime feature engineering - colab_notebook

• twitter recsys - text nlp, datetime feature engineering - colab_notebook

• outbrain - multiple table joining - colab_notebook

• amazon product review - text nlp, datetime, feature-cross - colab_notebook

More Examples - completed example including training

Auto Feature Engineering vs. featuretools

• NYC Taxi fare auto data prepration: An example to show how RecDP_v2.0 automatically generating datetime and geo features upon 55M records. Tested with both Spark and Pandas(featuretools) as compute engine, show 21x speedup by spark.

load PIPELINE and execute

• twitter pipeline re-load and execute: An example to show how RecDP_v2.0 reload pipeline from json and do execution - use RecDP as compute engine.

Data Profiler Examples

• NYC Taxi fare Profiler: An example to show RecDP_v2.0 to profile data, including infer the potential data type, generate data distribution charts.

• twitter Profiler: An example to show RecDP_v2.0 to profile data, including infer the potential data type, generate data distribution charts.
