Introduction
The BME 688 gas sensor allows us to collect and manage recorded gas data and utilize it to train algorithms. With the capability to try different algorithms with different databases and settings, we can optimize the results. This article will guide you through the process of evaluating algorithm performance and deploying them on the BME 688 gas sensor.
🔍 Evaluating Algorithm Performance
In AI Studio, we can assess the performance of our trained algorithms. The overview provides key metrics such as the heater profile, duty cycle used during data recording, and prediction accuracy. The prediction accuracy tells us how often the algorithm's predictions on the validation data were correct. We can dive deeper into the details and analyze the confusion matrix, which demonstrates the algorithm's ability to distinguish between coffee and neutral air. It is crucial to have high diagonal numbers and low off-diagonal numbers, indicating accurate predictions.
⚙️ Deployment of Algorithms on BME 688 Gas Sensor
Once satisfied with the algorithm's performance, we can proceed to deploy it on the BME 688 gas sensor. The deployment process ensures that the algorithm is ready to make predictions in real-world scenarios. By successfully deploying algorithms, we can utilize the sensor effectively and obtain reliable results.
📊 Overview of Training Results
When training algorithms, it is essential to review the training results carefully. However, we must be cautious with the results, as they can be deceivingly perfect. Overfitting can occur when the algorithm adapts too closely to a specific dataset, resulting in excellent performance on that data but limited ability to predict variations. To combat this, it is crucial to record enough data with variance to ensure the algorithm's overall robustness.
📉 Understanding Confusion Matrix
The confusion matrix provides valuable insights into an algorithm's performance. It showcases the algorithm's predictive accuracy for different classes. With the correct analysis of the confusion matrix, we can identify any shortcomings and fine-tune the algorithms accordingly. Aim for high accuracy and minimal false predictions to achieve optimal results.
🔄 Ensuring Robustness of Algorithm
To ensure the robustness of the algorithm, it is crucial to consider the variance in training data. If we train the algorithm with limited variations, we cannot assume it will work effectively in different sensor, gas, or surrounding conditions. By diversifying the training data, we establish a more robust algorithm that can handle varying scenarios.
🔀 Multiple Configurations in Gas Data
In some cases, the gas data includes multiple configurations. AI Studio automatically detects this and trains individual algorithms for each configuration. Each algorithm performs differently and has its own set of performance indicators. Analyzing these indicators provides valuable insights into the algorithm's behavior under different configurations, allowing us to optimize its performance.
💾 Exporting Algorithms
AI Studio offers the option to export trained algorithms for further use. By selecting the export button, AI Studio generates multiple files. These files, including the .config, .h, and .csv files, contain essential information for integrating the algorithm with the BSEC library by Bosch sensortec. For more detailed instructions, refer to the Bosch sensortec website.
🔌 Integration with BSEC Library
To seamlessly integrate the exported algorithm, we can utilize the .config and .h files in conjunction with the BSEC library by Bosch sensortec. This integration enables the algorithm to work harmoniously with the BME 688 gas sensor, enhancing its prediction capabilities and overall functionality.
💡 Custom Implementations
For advanced users, the exported .config and .csv files can be used for custom implementations. These files contain comprehensive information about the algorithm, allowing customization to specific requirements and objectives. Leveraging this flexibility, developers can create tailored solutions based on their unique needs.
📱 Live Testing with BME688 Development Kit and AI Studio Mobile App
To validate the algorithm's performance in real-world scenarios, we can conduct live testing using the BME688 development kit and the AI Studio mobile app. This enables us to observe how the algorithm performs in various situations and ensures its effectiveness before deploying it in practical applications.
