## Analysis Capabilities
|
||
|
||
### Behavioral Analysis
|
||
|
||
**Temporal Attractor Classification**:
|
||
|
||
- **Fixed Point**: Stable behavior, low anomaly risk
|
||
- **Limit Cycle**: Periodic patterns, normal operation
|
||
- **Strange Attractor**: Chaotic behavior, potential threat
|
||
- **Divergent**: Unstable patterns, high anomaly risk
|
||
|
||
**Lyapunov Exponent Calculation**:
|
||
|
||
```rust
|
||
let result = analyzer.analyze(&sequence).await?;
|
||
|
||
match result.lyapunov_exponent {
|
||
x if x > 0.0 => println!("Chaotic behavior detected"),
|
||
x if x == 0.0 => println!("Periodic behavior"),
|
||
_ => println!("Stable behavior"),
|
||
}
|
||
```
|
||
|
||
**Baseline Learning**:
|
||
|
||
```rust
|
||
// Train baseline on normal behavior
|
||
analyzer.train_baseline(&normal_sequences).await?;
|
||
|
||
// Detect deviations
|
||
let result = analyzer.analyze(&new_input, None).await?;
|
||
if result.anomaly_score > 0.8 {
|
||
println!("Significant deviation from baseline");
|
||
}
|
||
```
|
||
|
||
### Policy Verification
|
||
|
||
**Linear Temporal Logic (LTL)**:
|
||
|
||
Supports standard LTL operators:
|
||
|
||
- **Globally (G)**: Property must hold always
|
||
- **Finally (F)**: Property must hold eventually
|
||
- **Next (X)**: Property must hold in next state
|
||
- **Until (U)**: Property holds until another holds
|
||
|
||
**Policy Examples**:
|
||
|
||
```rust
|
||
use aimds_analysis::{PolicyVerifier, Policy};
|
||
|
||
let verifier = PolicyVerifier::new();
|
||
|
||
// "Users must always be authenticated"
|
||
let auth_policy = Policy::new(
|
||
"auth_required",
|
||
"G(authenticated)",
|
||
1.0 // priority
|
||
);
|
||
|
||
// "PII must eventually be redacted"
|
||
let pii_policy = Policy::new(
|
||
"pii_redaction",
|
||
"F(redacted)",
|
||
0.9
|
||
);
|
||
|
||
verifier.add_policy(auth_policy);
|
||
verifier.add_policy(pii_policy);
|
||
|
||
let result = verifier.verify(&trace).await?;
|
||
for violation in result.violations {
|
||
println!("Policy violated: {}", violation.policy_id);
|
||
}
|
||
```
|
||
|
||
### Anomaly Detection
|
||
|
||
**Multi-Dimensional Analysis**:
|
||
|
||
```rust
|
||
// Analyze sequence with multiple features
|
||
let sequence = vec![
|
||
vec![0.1, 0.2, 0.3], // Feature vector 1
|
||
vec![0.2, 0.3, 0.4], // Feature vector 2
|
||
// ... more vectors
|
||
];
|
||
|
||
let result = analyzer.analyze_sequence(&sequence).await?;
|
||
println!("Anomaly score: {:.2}", result.anomaly_score);
|
||
```
|
||
|
||
**Statistical Metrics**:
|
||
|
||
- Mean deviation from baseline
|
||
- Standard deviation analysis
|
||
- Distribution fitting (Gaussian, Student-t)
|
||
- Outlier detection (IQR, Z-score)
|
||
|
||
## Usage Examples
|
||
|
||
### Full Analysis Pipeline
|
||
|
||
```rust
|
||
use aimds_analysis::AnalysisEngine;
|
||
use aimds_core::{Config, PromptInput};
|
||
|
||
let analyzer = AnalysisEngine::new(Config::default()).await?;
|
||
|
||
// Behavioral + Policy verification
|
||
let input = PromptInput::new("User request sequence", None);
|
||
let detection = detector.detect(&input).await?;
|
||
|
||
let result = analyzer.analyze(&input, Some(&detection)).await?;
|
||
|
||
println!("Threat level: {:?}", result.threat_level);
|
||
println!("Anomaly score: {:.2}", result.anomaly_score);
|
||
println!("Policy violations: {}", result.policy_violations.len());
|
||
println!("Attractor type: {:?}", result.attractor_type);
|
||
```
|
||
|
||
### Baseline Training
|
||
|
||
```rust
|
||
// Collect normal behavior samples
|
||
let normal_sequences = vec![
|
||
PromptInput::new("Normal query 1", None),
|
||
PromptInput::new("Normal query 2", None),
|
||
// ... 100+ samples recommended
|
||
];
|
||
|
||
// Train baseline
|
||
analyzer.train_baseline(&normal_sequences).await?;
|
||
|
||
// Now analyze new inputs against baseline
|
||
let result = analyzer.analyze(&new_input, None).await?;
|
||
```
|
||
|
||
### LTL Policy Checking
|
||
|
||
```rust
|
||
use aimds_analysis::{PolicyVerifier, Policy, LTLChecker};
|
||
|
||
let mut verifier = PolicyVerifier::new();
|
||
|
||
// Add security policies
|
||
verifier.add_policy(Policy::new(
|
||
"rate_limit",
|
||
"G(requests_per_minute < 100)",
|
||
0.9
|
||
));
|
||
|
||
verifier.add_policy(Policy::new(
|
||
"auth_timeout",
|
||
"F(session_timeout)",
|
||
0.8
|
||
));
|
||
|
||
// Verify trace
|
||
let trace = vec![
|
||
("authenticated", true),
|
||
("requests_per_minute", 95),
|
||
("session_timeout", false),
|
||
];
|
||
|
||
let result = verifier.verify(&trace).await?;
|
||
for violation in result.violations {
|
||
println!("Violated: {} (confidence: {})",
|
||
violation.policy_id, violation.confidence);
|
||
}
|
||
```
|
||
|
||
### Threshold Adjustment
|
||
|
||
```rust
|
||
// Adjust sensitivity based on environment
|
||
analyzer.update_threshold(0.7).await?; // More sensitive
|
||
|
||
// Or per-analysis
|
||
let result = analyzer.analyze_with_threshold(
|
||
&input,
|
||
None,
|
||
0.9 // Less sensitive
|
||
).await?;
|
||
```
|
||
|
||
## Configuration

let config = Config {
|
||
behavioral_analysis_enabled: true,
|
||
behavioral_threshold: 0.75,
|
||
policy_verification_enabled: true,
|
||
..Config::default()
|
||
};
|
||

||
let analyzer = AnalysisEngine::new(config).await?;
|
||
```
|
||
|
||
## Integration with Midstream Platform
|
||
|
||
The analysis layer uses production-validated Midstream crates:
|
||
|
||
- **[temporal-attractor-studio](../../../crates/temporal-attractor-studio)**: Chaos analysis, Lyapunov exponents, attractor classification
|
||
- **[temporal-neural-solver](../../../crates/temporal-neural-solver)**: Neural ODE solving for temporal verification
|
||
- **[strange-loop](../../../crates/strange-loop)**: Meta-learning for pattern optimization
|
||
|
||
All integrations use 100% real APIs (no mocks) with validated performance.
|
||
|
||
## Testing
|
||
|
||
Run tests:
|
||
|
||
```bash

|
||
cargo test --package aimds-analysis --test integration_tests
|
||
|
||
# Benchmarks
|
||
cargo bench --package aimds-analysis
|
||
```
|
||
|

## Monitoring
|
||
|
||
### Metrics
|
||
|
||
Prometheus metrics exposed:
|
||
|
||
```rust
|
||
// Analysis metrics
|
||
aimds_analysis_requests_total{type="behavioral|policy|combined"}
|
||
aimds_analysis_latency_ms{component="behavioral|policy"}
|
||
aimds_anomaly_score_distribution
|
||

// Performance metrics
|
||
aimds_baseline_training_time_ms
|
||
aimds_attractor_classification_latency_ms
|
||
aimds_ltl_verification_latency_ms
|
||
```
|
||
|
||
### Tracing
|
||
|
||
Structured logs with `tracing`:
|
||
|
||
```rust
|
||
info!(
|
||
anomaly_score = result.anomaly_score,
|
||
attractor_type = ?result.attractor_type,
|
||
violations = result.policy_violations.len(),
|
||
latency_ms = result.latency_ms,
|
||
"Analysis complete"
|
||
);
|
||
```
|
||
|
||
## Use Cases
|
||
|
||
### Multi-Agent Coordination
|
||
|
||
Detect anomalous agent behavior:
|
||
|
||
```rust
|
||
// Analyze agent action sequences
|
||
let agent_trace = vec![
|
||
agent.action_at(t0),
|
||
agent.action_at(t1),
|
||
// ... temporal sequence
|
||
];
|
||
|
||
let result = analyzer.analyze_sequence(&agent_trace).await?;
|
||
if result.anomaly_score > 0.8 {
|
||
coordinator.flag_agent(agent.id, result).await?;
|
||
}
|
||
```
|
||
|
||
### API Gateway Security
|
||
|
||
Enforce rate limits and access policies:
|
||
|
||
```rust
|
||
// Define policies
|
||
verifier.add_policy(Policy::new(
|
||
"rate_limit",
|
||
"G(requests_per_second < 100)",
|
||
1.0
|
||
));
|
||
|
||
// Verify each request
|
||
let result = verifier.verify(&request_trace).await?;
|
||
if !result.violations.is_empty() {
|
||
return Err("Policy violation");
|
||
}
|
||
```
|
||
|
||
### Fraud Detection
|
||
|
||
Identify unusual transaction patterns:
|
||
|
||
```rust
|
||
// Train on normal transactions
|
||
analyzer.train_baseline(&normal_transactions).await?;
|
||
|
||
// Analyze new transaction
|
||
let result = analyzer.analyze(&new_transaction, None).await?;
|
||
if result.anomaly_score > 0.9 {
|
||
fraud_system.flag_for_review(new_transaction).await?;
|
||
}
|
||
```
