Using with Other IBM Tools

Watson Studio plays nice with IBM's other toys:

Watson Machine Learning: Get your models out there
SPSS Modeler: Build models without code
Cognos Analytics: Make your data look pretty

For instance, SPSS Modeler lets you drag-and-drop your way to a model right inside Watson Studio.

Whether you're flying solo or part of a big team, Watson Studio's got the flexibility to fit your style.

Preparing and Analyzing Data

Watson Studio packs a punch when it comes to getting your data ready for analysis. Here's what you need to know:

Adding Data

Getting data into Watson Studio is a breeze:

Hit the Assets tab in your project
Click Add to project > Data
Upload files or link to external sources

Watson Studio plays nice with CSV, JSON, and even images. For instance, you could toss in a CSV file called "german_credit_data.csv" to dig into credit risk factors.

Cleaning Up Data

Data Refinery is your cleanup buddy. Here's how it works:

Pick your dataset
Click Refine
Choose your cleanup moves

You might need to:

Kick out empty rows
Fix wonky data types
Deal with missing info

Pro tip: Save your cleanup steps as a "flow" to use again later.

Looking at Data Closely

Watson Studio lets you get up close and personal with your data:

Data profiling: Get the lowdown on each column
Sampling: Peek at a slice of big datasets
Filtering: Zero in on specific data points

For example, data profiling can help you spot oddball income values in your credit risk dataset that might throw off your analysis.

Making Charts and Graphs

Pictures are worth a thousand words, right? Watson Studio's got you covered:

Chart Type	When to Use It
Bar charts	Comparing stuff
Line charts	Spotting trends
Scatter plots	Finding connections
Heat maps	Showing data hotspots

To whip up a visualization:

Click Visualizations in Data Refinery
Pick your columns
Choose your chart style

You could create a scatter plot of credit amount vs. age to see if there's any link between these factors in your credit risk data.

Machine Learning in Watson Studio

Watson Studio packs a punch when it comes to machine learning. From basic models to cutting-edge AI, it's got you covered. Here's how to make the most of it:

Machine Learning Basics

Watson Studio breaks down machine learning into bite-sized steps:

Clean your data
Pick an algorithm
Train your model
Test it out
Put it to work

Making and Training Models

Want to create a model? Here's how:

Kick off a new project
Toss in your data
Go for "AutoAI experiment" or Jupyter Notebooks
Pick what you want to predict
Let Watson Studio do its thing

Say you've got customer data and want to predict who's likely to leave. Just upload that CSV and Watson Studio will walk you through the rest.

Using AutoAI

AutoAI is Watson Studio's secret sauce. It's like having a data scientist in your pocket. It:

Preps your data
Picks the best algorithms
Builds model pipelines

Using it is a breeze:

Hit "Add to project" > "AutoAI experiment"
Point it to your data
Tell it what to predict
Sit back and watch the magic happen

AutoAI will cook up a bunch of models and rank them. You just pick the one that fits best.

Checking and Improving Models

Watson Studio gives you tools to fine-tune your models:

Tool	What it does
Model evaluation	Shows how well your model performs
Feature importance	Tells you what really matters
Bias detection	Spots unfairness
Hyperparameter tuning	Tweaks your model's settings

To make your model better:

Look at how it's performing
Focus on what's important
Fix any bias
Play with the settings

Keep at it. The more you tweak and update, the better your model gets.

"Watson Studio's AutoAI tool lets you build and test models without writing a single line of code", says IBM. It's like having a data science superpower, no coding cape required.

Using Models in Real Life

You've built and trained your model in Watson Studio. Now what? Let's get it working in the real world.

Putting Models to Work

To use your model outside Watson Studio:

1. Deploy as a web service with Watson Machine Learning (WML)

2. Upload to Deployment Space in IBM Cloud

3. Create a deployment script using WML Python API

Here's a quick deployment example:

python3 model_deploy_pipeline.py ./model_file ../path/to/project/ ../credentials.yaml

After deployment, access predictions via endpoint requests or the ibm_watson_machine_learning Python library.

Watching How Models Perform

Use Watson OpenScale to keep tabs on your model. It helps you monitor accuracy, detect drift, and spot fairness issues.

To set it up:

Create a Watson OpenScale Data Mart
Link to your Watson Machine Learning service
Turn on model monitoring

Watson OpenScale will track key metrics and flag any problems.

Keeping Track of Model Versions

As you update your model:

Create a new version each time
Use client.deployments.create to deploy new versions
Keep older versions for comparison or rollback

Using Models with Other Programs

Your model can play nice with other tools:

Integration Method	Description
API Endpoints	Expose model as REST API
Batch Scoring	Process large datasets offline
Streaming	Real-time predictions on streaming data

For example, a fraud detection model could flag suspicious activities in real-time when integrated with a bank's transaction system.

Advanced Tools and Methods

Watson Studio packs a punch for data science pros. Let's dive into some of its coolest features.

Analyzing Data Over Time

AutoAI Time Series is Watson Studio's secret weapon for time-based data. It's like having a data scientist on autopilot, handling everything from prep to model picking.

What can it do? Here's the scoop:

Preps data and builds models automatically
Tweaks parameters and trains models
Picks the best forecasting model

Real-world example? An power company could use it to predict electricity demand. Feed in client usage data, and boom - better forecasts and smarter production planning.

Working with Map Data

Watson Studio teamed up with Mapbox to beef up its location smarts. Now you can squeeze more juice out of your geo data.

Some nifty geo tricks:

Projection-free Ellipsoidal support
Native geohashes
ST_GEOHASHVALUE function (new kid on the block)

These let you run fancy geo analytics right in Watson using SQL queries.

Making Better Decisions

Watson Studio's got your back when it comes to smart choices. Take the Dialog skill analysis notebook for Watson Assistant:

Spots weird stuff in training data
Crunches performance numbers (Accuracy, Precision, Recall, F1)
Shows you where to improve

There's also the "Measure Watson Assistant Performance" notebook for checking coverage and effectiveness.
