Data analysis agent pipeline in Agentic Ai - Model Pipeline Trace

Model Pipeline - Data analysis agent pipeline

This pipeline shows how a data analysis agent takes raw data, cleans it, extracts useful features, learns patterns with a model, improves its predictions over time, and finally makes predictions on new data.

Data Flow - 6 Stages

1Raw Data Input

1000 rows x 10 columns→Receive raw data with missing values and noise→1000 rows x 10 columns

[{'age': 25, 'income': 50000, 'purchased': 0}, ...]

↓

2Data Cleaning

1000 rows x 10 columns→Fill missing values and remove outliers→1000 rows x 10 columns

[{'age': 25, 'income': 50000, 'purchased': 0}, ...] (no missing values)

↓

3Feature Engineering

1000 rows x 10 columns→Create new features like income brackets and normalize data→1000 rows x 12 columns

[{'age': 25, 'income': 50000, 'income_bracket': 2, 'purchased': 0}, ...]

↓

4Model Training

800 rows x 12 columns→Train classification model on training set→Model trained to predict purchase

Logistic regression model trained on 800 samples

↓

5Validation

200 rows x 12 columns→Evaluate model on validation set→Validation accuracy and loss metrics

Accuracy: 0.85, Loss: 0.35

↓

6Prediction

New data 1 row x 12 columns→Make prediction on new customer data→Prediction probability and class label

{'income': 60000, 'income_bracket': 3} -> Predicted purchase: 1 (0.78 probability)

Key Insight

This visualization shows how data flows through cleaning, feature creation, and model training stages. The training trace confirms the model learns by reducing loss and improving accuracy. The prediction trace explains how raw input is transformed and how the model outputs a probability that is converted to a final decision.
