Greenscreens.ai’s machine learning models are used to predict prices of future loads based on patterns found in historical load data.

Before we dive into machine learning, it’s important to note the difference between Machine Learning and Artificial Intelligence.

Artificial Intelligence is the general ability to emulate human thought and behavior through computer science, while machine learning refers to the technologies and algorithms that enable systems to identify patterns, make decisions, and improve their capabilities through experience and data. AI is an umbrella term for computer software, with many subsets that work to achieve desired human-like outcomes. Other subsets within AI include deep learning, natural language processing and robotics.

The focus of artificial intelligence is on developing computers or robots that can mimic human behavior. The ultimate goal for AI-enabled programs is to provide information automatically and trigger actions without the need for specific human interaction. Artificial intelligence is already present in many of the technologies we use today. In fact, machine learning is the primary way most people commonly interact with AI.

Popular uses for artificial intelligence include:

Many companies continue to explore AI as a means of increasing productivity and optimizing their workforce with automation and chatbots.

The key differences:

Many different types of AI models can be used to make predictions based on previous data. Different models have different structures, and each has its strengths and weaknesses.

It uses feedback to adjust the weight it assigns to each factor in determining a result. Over time, the model gets better and better at predicting outcomes.

The algorithms and parameters that make up a machine learning model can be optimized through training for better performance and more accurate predictions.

Each sample (a load in the case of Greenscreens) is represented by a set of features. Features represent important information about the load, such as its origin, its destination, and the distance between them. Every historical load is also accompanied by its price, which tells the model what kind of prediction to offer, given the conditions encapsulated in the load’s features.

Now let's apply that to freight pricing. A Greenscreens AI can take a lot of variables (origin, destination, weight, fuel, etc.) into account. It notes how each variable affects rate pricing in the context of all the other variables, and predicts a rate.

A human could arrive at the same prediction, given enough time, but a machine learning system can offer reliable predictions a lot more efficiently. It can even uncover dependencies and trends that might be hard for a busy human to catch, such as time-of-day effects on capacity and price. Machine learning multiplies the speed and efficiency of the human’s work. The model, however, needs to start with real-world information–in this case, historical loads.

Due to the volatility of the freight market, using simple historical averages to predict current rates will often produce inaccurate and partial results. AI models use advanced statistical analysis to make predictions and measure the Confidence of those predictions. They also deal with data scarcity in a much more consistent and controlled way than plain averages. Predictive models can take into account many different features of a load, identify correlations that would be difficult to the human eye to recognize, and provide a rate that has considered all of those features.

Greenscreens automates the process of statistical analysis in order to deliver you reliable and easy-to-read rate predictions.

We start by dividing our historical data into three sets: a training set, a validation set, and a test set. The training set typically contains the majority of the historical data. The additional sets outside of the training set measure the model’s performance on previously unseen data.

The training phase provides us with multiple competing models that differ in the way they operate, the features they use, or the weight they give to different parameters. For instance, one model might assign more importance to origin and distance, while another prioritizes load size. We need to select the model that provides the most accurate rate predictions, either manually or by an automatic selection workflow.

The next step uses the validation set, which contains samples previously unseen by the model, to evaluate the models and select the most accurate ones. The models are given features of the loads within the validation set without their outcomes--in this case price--and each model's predictions are compared to the actual values from the sample. Each model is graded on how closely it predicted the validation set as a whole. We choose the most accurate model and refine it further with the values from the validation set.

We still need an objective assessment of the selected model’s results on previously unseen data, so we can be sure that the success of that model didn’t involve a bit of luck. So we use the test set, which is still new to the model. This final test gives an objective evaluation of the model’s real-world performance.

The Greenscreens app shows the model’s performance against the test set in the Rate Accuracy Report, which measures the accuracy of the rate predicted by Greenscreens compared to the actual booked rate of the load, so you can see how close your model is coming to actual rates at any time. If the model seems off, our engineers can take a look and find out why.

Origin and destination, pickup date, transport type, transport mode, carrier and customer costs, and linehaul cost are the most important features for rate prediction. Greenscreens.ai’s models also learn from a wider set of brokerage data. As of May 2023, the Greenscreens model employs data from 120+ brokerages. It can also learn from external data sources and macroeconomic features for increased accuracy.

Greenscreens predicts this rate when you enter a lane and transport type into our user interface or Greenscreens-integrated TMS. This rate is influenced by your historical data and reflects your company’s individual buying behavior against the current market conditions, but is also often influenced by external data, such as the data we receive for other brokerages (the Greenscreens.ai network).

It can be determined through the creation of pricing rules, or generated by the customer’s historic margin on the lane. Without rules or historical data, the markup will default to a baseline of 15%. Here’s an example of a Target Buy Rate: let’s say that for a particular shipment we predict a rate of $1,000. Currently the brokerage has a pricing rule stating that all loads originating in Seattle should have a 10% markup. The sell rate in this case would be $1,100. A markup of 20% would return a rate of $1,200, and so on.

The Network Rate has no bias towards any one brokerage’s data. It can be lower or higher than the Target Buy Rate, depending on how the brokerage books freight on the underlying lane or similar lanes.

A Greenscreens machine learning model recognizes similarities and connections between lane features, such as origin and destination, which lets it make reliable predictions even when historical data for a particular lane isn’t available. The Network Rate widget in the Greenscreens user interface provides numbers for similar historical lanes from Greenscreens’ network, so you can compare the predicted lane to similar ones. This is especially useful when making predictions for lanes with little or no historical data.

AI models are a sophisticated tool that can produce accurate and insightful price predictions for truck brokers. It’s important to understand the capabilities of machine learning.

Greenscreens keeps track of the average margin of error (expressed as percentage) in a model’s predictions to ensure that the AI is working as it should. Since the accuracy of predictions will always show some amount of variation, we use the overall margin of error to assess a model’s performance. Even allowing for these variations, an AI with a low margin of error will still be far and away more accurate than a simple average of rates.

Every Greenscreens rate prediction is accompanied by a Confidence Level.

The Confidence Level tells you how much confidence you can safely have in a rate prediction. is intended to take the guesswork out of how hard it will be to cover a load at the given price based on the current market conditions. If the model has enough consistent data to narrow down the spread of potential rates, the Confidence Level will be high. If the model doesn't have the data it needs for an accurate prediction, we recommend being more cautious with quotes.

The Confidence Level is primarily determined by three things:

For every prediction, Greenscreens provides a Network Rate prediction and a Target Buy Rate prediction. The Network Rate prediction is produced by the network model which uses our entire network's load data. The Target Buy Rate is generated by a model trained to predict a specific brokerage’s rates based on their individual buying behavior and buying power, but using both the brokerage’s data and data from Greenscreens’ entire network. Since the Network Rate prediction model works with a different data set, Confidence Levels will vary between these two predictions. This lets you compare your rates to those in the Greenscreens.ai network.

The Network Rate Confidence Level is not specific to any one brokerage, but represents the likelihood that any brokerage within the Greenscreens.ai network will be able to buy a specific lane at a specific price. If a brokerage has a smaller spread of truck rates on a given lane, with more volume consistency, the Target Buy Rate may have a higher Confidence Level. If a brokerage has no historical volume on a lane (and the model was unable to rely on history from other brokerages that were deemed to be similar or other lanes that would be strongly correlated to the requested lane), where the network has a large quantity of historical volume, the Network Rate Confidence will usually be higher.

Machine learning lets us predict rates for previously unseen lanes by isolating and filtering for specific load features. The models recognize similarities between certain features in the context of historical rates, which allows them to make reliable predictions even if the lane is new to the brokerage. This is another example of the efficiency of machine learning – a human could easily look up a lane with a similar origin and destination, but a machine learning model can find many kinds of similarities and connections across your entire shipping history very quickly and come up with a faster and more reliable prediction, backed up by more extensive data.

Greenscreens’ Accuracy Report breaks out the margin of error numbers for new lanes, so you can see exactly how well the model is doing at predicting rates for lanes with no historical data.
