To begin using Turi Create, you need to have Python installed on your system. Once you have Python, the installation process is straightforward. You can install Turi Create using pip:
pip install turicreate
Basic Workflow
Once installed, users typically follow a simple workflow to create a machine learning model with Turi Create. Here’s a breakdown of the core steps involved:
-
Load Data: Import your dataset into Turi Create. Supported formats include CSV, JSON, and even image directories.
-
Explore Data: Use various built-in visualization tools to understand your data better, identifying patterns or anomalies that may inform your model's design.
-
Create a Model: Choose an appropriate model type based on your task—be it classification, regression, or recommendation—and train the model with your data.
-
Evaluate Model: Assess the performance of your model using metrics like accuracy, precision, and recall, which provide insights into its efficacy.
-
Deploy Model: Once satisfied with the model's performance, you can deploy it for use in production, making predictions on new data as it becomes available.
Example: Building a Simple Image Classifier
To illustrate the ease of use and power of Turi Create, let’s look at a simple example of building an image classifier.
Step 1: Load Your Dataset
First, ensure that your images are organized in a way that Turi Create can interpret. For instance, images can be stored in folders named after their classes:
import turicreate as tc
data = tc.image_analysis.load_images('path/to/image_directory', as_supervised=True)
Step 2: Explore Data
Next, let’s visualize a few images from your dataset to ensure that everything is loaded correctly.
data['image'].explore()
Step 3: Create and Train the Model
Now, we can create a model using the deep learning classifier.
model = tc.image_classifier.create(data, target='label')
Step 4: Evaluate the Model
After training, it's crucial to evaluate the model's performance.
results = model.evaluate(data)
print(results)
Step 5: Make Predictions
Finally, you can use your trained model to classify new images:
predictions = model.predict(new_data)
Applications of Turi Create
Turi Create is versatile and can be applied in various industries and applications, such as:
- Retail: Developing recommendation systems to suggest products to users based on their previous purchases.
