Top 6 Machine Learning Algorithms for Classification
Machine Learning Basics for Supplier Classification
Types of Machine Learning Methods
Supplier classification relies on two main machine learning approaches: supervised and unsupervised learning.
- Supervised learning uses labeled data to classify suppliers into specific categories. For example, a manufacturing company might train its model to sort suppliers into categories like excellent, good, satisfactory, or unsatisfactory based on their past performance.
- Unsupervised learning, on the other hand, identifies natural groupings in supplier data without relying on predefined categories.
Here’s a quick overview of how these methods differ:
| Learning Type | Key Features | Best Used For |
|---|---|---|
| Supervised | Predicts specific outcomes | Performance ratings, risk assessments, compliance categorization |
| Unsupervised | Discovers patterns | Supplier segmentation, relationship analysis, anomaly detection |
For either method to work effectively, high-quality, well-prepared data is a must.
Key Data Points for Classification
The success of any supplier classification model hinges on the quality of the data it uses. Here are the most important data points to focus on:
-
Performance Indicators
These are the backbone of supplier evaluation. Metrics like delivery times, quality ratings, and compliance scores are critical. Missing data in these areas can severely affect the model's accuracy. -
Financial Metrics
Metrics that reflect financial stability are equally important. For instance, a telecom company found that addressing gaps in financial data improved its classification accuracy from 72% to 80%. -
Operational Data
This includes details like production capacity, geographic location, and response times. When operational data is incomplete, techniques like KNN or multiple imputation can help fill the gaps. Alternatively, algorithms like XGBoost are designed to handle missing values directly.
For handling complex or high-dimensional supplier data, Support Vector Machines (SVM) can be effective. Meanwhile, Random Forests combine multiple decision trees to deliver reliable predictions.
Data Preparation Steps
Data Gathering and Cleanup
Preparing data properly is critical for accurate supplier classification. SourceDogg highlights the importance of setting clear goals for data collection. This helps define the types of data you need, how often to collect it, and where to source it from.
Cleaning up data involves a few key actions:
-
Initial Data Assessment
Take a close look at your current supplier data. Connie Jensen from TealBook warns, "Supplier data can become stale quickly, disrupting multiple departments". -
Data Cleansing Process
- Back up all vendor master data.
- Resolve any open items in master files.
- Confirm the accuracy of primary contact details.
- Remove or block inactive suppliers.
- Get rid of duplicate vendor records.
-
Standardization Implementation
The Classification Guru assisted a client in standardizing supplier data, successfully classifying about 95% of thousands of global suppliers in just a few weeks. This effort was crucial for developing accurate spend analytics while setting up a new global indirect procurement function.
Once your data is clean and standardized, the next step is creating features tailored to support accurate classification.
Creating Useful Data Features
Turning raw supplier data into actionable features requires systematic transformation and enrichment. Susan Walsh from The Classification Guru explains, "Data accuracy is an investment, not a cost".
Here’s how different types of data should be handled:
| Data Type | Processing Method | Purpose |
|---|---|---|
| Internal Data | Extract from ERP and accounting systems | Provides core business metrics |
| External Data | Gather supplier info from online sources | Adds market context |
| Transaction Data | Align to a unified taxonomy | Ensures consistent classification |
Key steps for feature creation include:
-
Data Consolidation
Collect and merge data from all sources into a single, centralized database. -
Supplier Normalization
Standardize supplier names to address inconsistencies like global variations, division-specific naming, corporate suffixes, and typos. -
Classification Structure
Build a taxonomy tailored to your organization’s needs. Ensure the features you create align with business goals while maintaining consistency.
The accuracy of your machine learning model hinges on these preparation steps. Susan Walsh captures it perfectly: "Supplier normalization is an exceptionally efficient way of doing this – I say it's like eating chocolate without the calories".

Selecting and Using ML Models
Common Classification Algorithms
Once you have clean, detailed supplier data, choosing the right machine learning (ML) model becomes critical for accurate classification. The best algorithm depends on your data's structure and your specific goals.
Decision trees are particularly useful for breaking down supplier data into simple, binary decisions. They make the classification process easy to follow and explain, which is helpful when procurement teams need to justify decisions to stakeholders.
Here’s how some common algorithms match different supplier classification needs:
| Algorithm Type | Best Used For | Key Advantage |
|---|---|---|
| Decision Trees | Categorical supplier data | Straightforward decision paths |
| Random Forest | Complex supplier attributes | Improved accuracy with multiple trees |
| K-Means Clustering | Supplier segmentation | Identifies natural groupings |
Research highlights that companies using effective supplier classification can see:
- 5% to 10% cost savings
- 20% to 50% lower risk exposure
After selecting the right algorithm, the next step is building a model tailored to your supplier data.
Model Development Process
Turning your algorithm choice into a working model involves a structured, step-by-step process. This ensures the model meets organizational goals while adhering to data privacy standards.
Here are the main stages:
-
Initial Model Setup
Define what success looks like. Ensure your dataset includes key metrics such as financial performance, delivery history, industry expertise, and geopolitical considerations. -
Training and Validation
Use version control to track updates to the model’s structure and parameters. This helps maintain clarity and consistency throughout development. -
