# 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.api import FeatrixSphere
# Initialize client
featrix = FeatrixSphere("http://your-sphere-server.com")
2. Upload Data & Train Model
# Option A: Upload CSV file
fm = featrix.create_foundational_model(
name="my_model",
data_file="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
fm = featrix.create_foundational_model(name="my_model", df=df)
# Wait for the embedding space to train
fm.wait_for_training()
# Create a binary classifier for your target column
predictor = fm.create_binary_classifier(
target_column="is_fraud",
name="fraud_detector"
)
# Wait for predictor training
predictor.wait_for_training()
3. Make Predictions
# Single prediction
result = predictor.predict({
"transaction_amount": 1500.00,
"merchant_category": "gas_station",
"location": "highway_exit"
})
print(result.predicted_class) # 'fraud'
print(result.confidence) # 0.95
# Batch predictions
results = predictor.predict_batch([
{"amount": 100, "merchant": "grocery"},
{"amount": 5000, "merchant": "unknown_vendor"},
])
🎨 Beautiful Examples
📊 DataFrame Upload Workflow
import pandas as pd
from featrixsphere.api import FeatrixSphere
# 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!
featrix = FeatrixSphere("https://sphere-api.featrix.com")
fm = featrix.create_foundational_model(name="transactions", df=df)
fm.wait_for_training()
# Create predictor
predictor = fm.create_binary_classifier(
target_column="is_fraud",
name="fraud_detector"
)
predictor.wait_for_training()
# Make predictions
result = predictor.predict({"amount": 1500, "merchant": "gas_station"})
print(result.predicted_class) # 'fraud' or 'legitimate'
print(result.confidence) # 0.95
🏦 Fraud Detection
# Create a binary classifier for fraud detection
predictor = fm.create_binary_classifier(
target_column="is_fraudulent",
name="fraud_classifier"
)
predictor.wait_for_training()
# Detect fraud in real-time
result = predictor.predict({
"amount": 5000,
"merchant": "unknown_vendor",
"time": "3:00 AM",
"location": "foreign_country"
})
print(result.predicted_class) # 'fraud'
print(result.confidence) # 0.98 ⚠️
🎯 Customer Segmentation
# Create a multiclass classifier
predictor = fm.create_multi_classifier(
target_column="customer_value_segment", # high/medium/low
name="customer_segmentation"
)
predictor.wait_for_training()
# Classify new customers
result = predictor.predict({
"age": 34,
"income": 75000,
"purchase_history": "electronics,books",
"engagement_score": 8.5
})
print(result.predicted_class) # 'high_value'
print(result.probabilities) # {'high_value': 0.87, 'medium_value': 0.12, 'low_value': 0.01}
🏠 Real Estate Pricing
# Create a regressor for continuous values
predictor = fm.create_regressor(
target_column="sale_price",
name="price_predictor"
)
predictor.wait_for_training()
# Get price estimates
result = predictor.predict({
"bedrooms": 4,
"bathrooms": 3,
"sqft": 2500,
"neighborhood": "downtown",
"year_built": 2010
})
print(result.predicted_value) # 485000.0 (predicted price: $485,000)
🔍 Advanced Features
Vector Embeddings
# Get neural embeddings for any record
fm = featrix.foundational_model("session-id")
embedding = fm.encode({
"text": "customer complaint about billing",
"category": "support",
"priority": "high"
})
print(f"3D embedding: {embedding['embedding_short']}")
print(f"Full embedding dimension: {len(embedding['embedding_long'])}")
# Embedding dimension: 512 (rich 512-dimensional representation!)
Similarity Search
# Find similar records using neural embeddings
similar = fm.similarity_search({
"description": "suspicious late night transaction",
"amount": 2000
}, k=10)
print("Similar transactions:")
for record in similar:
print(f"Distance: {record['distance']:.3f} - {record['record']}")
Working with Existing Models
# Load an existing foundational model
fm = featrix.foundational_model("session-123")
print(fm.status) # 'ready'
# List all predictors
predictors = fm.list_predictors()
for pred in predictors:
print(f"{pred.name}: {pred.target_column} ({pred.accuracy:.2%})")
# Get a specific predictor
predictor = fm.get_predictor("pred-456")
result = predictor.predict({"feature": "value"})
Training Monitoring

🎯 Pro Tips
🚀 Performance Optimization
# Use batch predictions for better throughput
results = predictor.predict_batch(records_list)
# 10x faster than individual predictions!
# Featrix auto-tunes model parameters for your data
predictor = fm.create_binary_classifier(
target_column="target",
name="my_predictor"
)
🎨 Data Preparation
# Your CSV just needs:
# ✅ Clean column names (no spaces/special chars work best)
# ✅ 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 model status
fm = featrix.foundational_model("session-id")
print(f"Status: {fm.status}")
# Check predictor accuracy
predictor = fm.get_predictor("pred-id")
print(f"Accuracy: {predictor.accuracy:.2%}")
