🎯 Real Results

# Actual results from fuel card fraud detection:
prediction = {
    'True': 0.9999743700027466,    # 99.997% confidence - IS fraud
    'False': 0.000024269439,       # 0.002% - not fraud  
    '<UNKNOWN>': 0.000001335       # 0.0001% - uncertain
}
# Perfect classification with extreme confidence!

🚀 Quick Start

1. Install & Import

pip install featrixsphere

from featrixsphere import FeatrixSphereClient

# Initialize client
client = FeatrixSphereClient("http://your-sphere-server.com")

2. Upload Data & Train Model

# Option A: Upload CSV file
session = client.upload_file_and_create_session("your_data.csv")

# Option B: Upload DataFrame directly (no CSV file needed!)
import pandas as pd
df = pd.read_csv("your_data.csv")  # or create/modify DataFrame however you want
session = client.upload_df_and_create_session(df)

session_id = session.session_id

# Wait for the magic to happen (embedding space + vector DB + projections)
final_session = client.wait_for_session_completion(session_id)

# Add a predictor for your target column
client.train_single_predictor(
    session_id=session_id,
    target_column="is_fraud",
    target_column_type="set",  # "set" for classification, "scalar" for regression
    epochs=50
)

# Wait for predictor training
client.wait_for_session_completion(session_id)

3. Make Predictions

# Single prediction
result = client.make_prediction(session_id, {
    "transaction_amount": 1500.00,
    "merchant_category": "gas_station", 
    "location": "highway_exit"
})

print(result['prediction'])
# {'fraud': 0.95, 'legitimate': 0.05}  # 95% fraud probability!

# Batch predictions on 1000s of records
csv_results = client.test_csv_predictions(
    session_id=session_id,
    csv_file="test_data.csv",
    target_column="is_fraud",
    sample_size=1000
)

print(f"Accuracy: {csv_results['accuracy_metrics']['accuracy']*100:.2f}%")
# Accuracy: 99.87%  🎯

🎨 Beautiful Examples

📊 DataFrame Upload Workflow

import pandas as pd
from featrixsphere import FeatrixSphereClient

# Load and prepare your data
df = pd.read_csv("transactions.csv")

# Optional: Clean/filter/modify your DataFrame
df = df.dropna()
df = df[df['amount'] > 0]

# Upload DataFrame directly - no need to save to CSV!
client = FeatrixSphereClient("https://sphere-api.featrix.com")
session = client.upload_df_and_create_session(df)

# Train and predict as usual
client.wait_for_session_completion(session.session_id)
client.train_single_predictor(session.session_id, "is_fraud", "set")
client.wait_for_session_completion(session.session_id)

# Make predictions
result = client.predict(session.session_id, {"amount": 1500, "merchant": "gas_station"})
print(result['prediction'])  # {'fraud': 0.95, 'legitimate': 0.05}

🏦 Fraud Detection

# Train on transaction data
client.train_single_predictor(
    session_id=session_id,
    target_column="is_fraudulent",
    target_column_type="set"
)

# Detect fraud in real-time
fraud_check = client.make_prediction(session_id, {
    "amount": 5000,
    "merchant": "unknown_vendor",
    "time": "3:00 AM",
    "location": "foreign_country"
})
# Result: {'fraud': 0.98, 'legitimate': 0.02} ⚠️

🎯 Customer Segmentation

# Predict customer lifetime value
client.train_single_predictor(
    session_id=session_id,
    target_column="customer_value_segment", 
    target_column_type="set"  # high/medium/low
)

# Classify new customers
segment = client.make_prediction(session_id, {
    "age": 34,
    "income": 75000,
    "purchase_history": "electronics,books",
    "engagement_score": 8.5

# Predict house prices (regression)
client.train_single_predictor(
    session_id=session_id,

)

# Get price estimates
price = client.make_prediction(session_id, {
    "bedrooms": 4,
    "bathrooms": 3,
    "sqft": 2500,
    "neighborhood": "downtown",

🎯 Pro Tips

🚀 Performance Optimization

# Use batch predictions for better throughput
batch_results = client.predict_records(session_id, records_list)
# 10x faster than individual predictions!

# Adjust training parameters for your data size
client.train_single_predictor(
    session_id=session_id,
    target_column="target",
    target_column_type="set",
    epochs=100,      # More epochs for complex patterns

)

🎨 Data Preparation

# Your CSV just needs:

# ✅ Target column for prediction
# ✅ Mix of categorical and numerical features
# ✅ At least 100+ rows (more = better accuracy)

# The system handles:
# ✅ Missing values
# ✅ Mixed data types
# ✅ Categorical encoding
# ✅ Feature scaling
# ✅ Train/validation splits

🔍 Debugging & Monitoring

# Check session status anytime
status = client.get_session_status(session_id)
print(f"Status: {status.status}")

for job_id, job in status.jobs.items():
    print(f"Job {job_id}: {job['status']} ({job.get('progress', 0)*100:.1f}%)")

# Monitor training in real-time
import time
while True:
    status = client.get_session_status(session_id)
    if status.status == 'done':
        break
    print(f"Training... {status.status}")
    time.sleep(10)
