### 2. Restart Claude Desktop App
**⚠️ IMPORTANT**: You need to restart Claude Desktop App for changes to take effect.
### 3. Test the Enhanced Features
```python
# Switch to the enhanced data analysis incarnation
switch_incarnation(incarnation_type="data_analysis")
# Try the new AI-powered insights
load_dataset(file_path="/path/to/your/data.csv", dataset_name="test_data", source_type="csv")
generate_insights(dataset_id="DATASET_ID", insight_types=["patterns", "quality", "recommendations"])
# Test advanced visualizations
visualize_data(dataset_id="DATASET_ID", chart_type="auto")
# Try machine learning features
detect_anomalies(dataset_id="DATASET_ID", method="isolation_forest")
cluster_analysis(dataset_id="DATASET_ID", method="kmeans")
```
## 🎯 NEW CAPABILITIES TO EXPLORE
### 🆕 **Enhanced Type Detection**
```python
# Now automatically detects:
# - Dates (multiple formats), Boolean values, Currency ($, €, £)
# - Percentages, Emails, URLs, Categorical data
# - With confidence scoring for data quality assessment
```
### 🆕 **Professional Visualizations**
```python
# Create publication-ready charts
visualize_data(dataset_id="your_dataset_id",
chart_type="correlation", # auto, histogram, scatter, box, correlation
save_path="/path/to/save/charts")
```
### 🆕 **AI-Powered Anomaly Detection**
```python
# Find outliers and anomalies automatically
detect_anomalies(dataset_id="your_dataset_id",
method="isolation_forest", # isolation_forest, local_outlier_factor, statistical
contamination=0.1) # Expected % of anomalies
```
### 🆕 **Smart Clustering Analysis**
```python
# Discover patterns and segments in your data
cluster_analysis(dataset_id="your_dataset_id",
method="kmeans", # kmeans, dbscan
n_clusters=None) # Auto-detects optimal number
```
### 🆕 **Time Series Analysis**
```python
# Analyze temporal data for trends and seasonality
time_series_analysis(dataset_id="your_dataset_id",
date_column="order_date",
value_columns=["sales", "revenue"],
frequency="auto") # daily, weekly, monthly, auto
```
### 🆕 **Automated Insights Engine**
```python
# Get AI-powered recommendations and quality assessment
generate_insights(dataset_id="your_dataset_id",
insight_types=["patterns", "quality", "recommendations"])
```
