Classification and Regression Trees (CART) are decision tree algorithms designed for both classification and regression tasks, making them highly versatile in thermal mapping predictions. Unlike the complexity of neural networks or ensemble methods, CART offers a straightforward approach, creating a direct link between input features and temperature outputs. This simplicity ensures clear decision-making pathways while meeting the demands for timely and dependable thermal predictions in industrial settings.
The algorithm works by splitting data into branches based on specific feature thresholds, resulting in an interpretable tree structure. This tree not only predicts temperature distributions but also identifies thermal anomalies, making it particularly useful for operational decisions and maintenance planning where clarity is essential.
Predictive Accuracy
CART models deliver reliable predictions, often assessed using metrics like Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and R-squared values. In thermally-aware task scheduling, tree-based and ensemble methods have demonstrated success rates ranging from 74.17% to 82.5%. Achieving high accuracy with CART depends heavily on effective feature selection and robust feature engineering.
Computational Efficiency
A standout benefit of CART is its computational efficiency compared to deep learning models. It demands significantly less processing power and memory, making it an excellent choice for environments with limited computational resources or for rapid prototyping needs.
Scalability for Large Datasets
CART performs well with moderately large datasets but may struggle with very large, high-dimensional data. To address this, preprocessing techniques such as feature selection or dimensionality reduction can enhance its scalability. For extremely large datasets, ensemble methods like Random Forests or Gradient Boosted Trees are often preferred, as they offer improved predictive performance.
Suitability for Real-Time Analysis
CART is particularly effective for real-time thermal mapping, thanks to its fast inference speed and minimal computational demands.

Next, we’ll explore Feedforward Neural Networks (FNNs), which are tailored for addressing more complex, non-linear thermal dynamics.
6. Feedforward Neural Networks (FNNs)
Feedforward Neural Networks (FNNs) offer a straightforward yet powerful approach to thermal mapping predictions, relying on a direct input-to-output structure. Unlike the simplicity of tree-based models like CART or the spatial processing strengths of CNNs, FNNs excel in capturing intricate temperature relationships through their layered design. This makes them particularly effective for applications like sensor-based thermal monitoring.
FNNs use a series of layers to map thermal inputs to temperature outputs. Their forward-only propagation design not only captures complex thermal dynamics but also keeps computational requirements manageable compared to more elaborate models.
Predictive Accuracy
FNNs deliver dependable predictions in thermal mapping tasks, though their performance depends on the complexity of the data. For instance, a 2024 study in Nature Scientific Reports demonstrated the effectiveness of a 3-layer FNN in predicting cooling efficiency from thermal images of photovoltaic panels. Using 390 labeled images, the model achieved a mean squared error (MSE) of 0.016, a mean absolute error (MAE) of 3.5%, and an R-squared value of 0.85.
In another example, a 2018 study by the U.S. Department of Energy highlighted the advantages of neural network–based models for runtime temperature predictions. These models achieved an average prediction error of about 2.9°C (roughly 5.2°F), outperforming linear regression methods, which averaged around 3.8°C (approximately 6.8°F). This accuracy proved valuable for thermal-aware scheduling, reducing peak system temperatures by as much as 11.9°C (around 21.4°F) and achieving an average reduction of 4.4°C (about 7.9°F).
Computational Efficiency
One of the major strengths of FNNs is their computational efficiency. Thanks to their straightforward architecture, they demand fewer resources compared to deeper models. This makes them an excellent choice for organizations with limited computational power or older infrastructure. Faster training times and lower hardware requirements mean FNNs can be implemented without significant investments in new technology.
Additionally, their streamlined design supports rapid data processing, enabling real-time decision-making. This efficiency makes FNNs a practical option for applications like live thermal monitoring, where quick insights are critical.
Scalability for Large Datasets
FNNs perform well with moderately large thermal datasets but face challenges when handling very large, high-dimensional data like detailed thermal imagery. Unlike models designed to capture spatial relationships, FNNs require preprocessing and feature engineering to manage such datasets effectively.
For large-scale industrial scenarios involving thousands of thermal images, raw images must be converted into numerical feature vectors, and datasets need careful labeling. While this preprocessing adds complexity, it allows FNNs to balance speed and accuracy, making them a reliable choice for many thermal mapping tasks.
Suitability for Real-Time Analysis
FNNs shine in real-time thermal monitoring thanks to their minimal computational requirements. Their ability to continuously process thermal data streams makes them ideal for automated systems that predict future temperature conditions based on historical sensor data.
Integrating FNNs into existing monitoring systems is relatively straightforward. They connect to real-time sensor data streams and automation platforms, processing preprocessed thermal data to generate predictions. These predictions can then trigger automated responses through APIs or middleware that link the model to facility management systems.
For organizations looking to implement FNNs in thermal mapping systems, platforms like Anvil Labs provide tools for managing diverse data types - such as thermal imagery, sensor readings, and 3D models - along with solutions for data processing, annotation, and integration into real-time workflows.
