United Airlines is one of the world’s largest airlines, serving millions of passengers each year. To ensure smooth operations and enhance customer experience, United Airlines relies on various technologies, including Optical Character Recognition (OCR). OCR is a technology that converts different types of documents, such as boarding passes and passports, into machine-readable text.
Building a cost-efficient OCR active learning pipeline is crucial for United Airlines to streamline their operations and improve efficiency. To achieve this, United Airlines has partnered with Amazon Web Services (AWS), a leading cloud computing platform. AWS provides a scalable and reliable infrastructure that enables United Airlines to process large volumes of data quickly and accurately.
The process of building a cost-efficient OCR active learning pipeline involves several key steps. Let’s explore each step in detail:
1. Data Collection: The first step is to collect a diverse set of data that represents the documents United Airlines encounters regularly. This includes boarding passes, passports, and other travel-related documents. The more diverse the dataset, the better the OCR model’s performance will be.
2. Data Annotation: Once the data is collected, it needs to be annotated. Annotation involves labeling each document with the correct text that appears on it. This labeled data is used to train the OCR model to recognize and extract text accurately.
3. Model Training: Using AWS’s machine learning services, United Airlines trains an OCR model using the annotated data. AWS offers various tools, such as Amazon Textract and Amazon Rekognition, which provide pre-trained models for OCR tasks. These models can be fine-tuned using United Airlines’ specific dataset to improve accuracy.
4. Active Learning: Active learning is a process that involves iteratively selecting the most informative samples from the unlabeled dataset for annotation. This helps improve the OCR model’s performance while minimizing the annotation effort. United Airlines leverages AWS’s active learning capabilities to select the most valuable samples for annotation, reducing costs and time spent on manual annotation.
5. Model Evaluation: After each iteration of active learning, the newly annotated data is used to retrain the OCR model. The model’s performance is evaluated using a separate validation dataset to ensure it meets United Airlines’ accuracy requirements. If necessary, further iterations of active learning can be performed to improve the model’s performance.
6. Deployment and Integration: Once the OCR model meets the desired accuracy level, it is deployed into United Airlines’ production environment. AWS provides seamless integration with existing systems, allowing United Airlines to incorporate OCR capabilities into their operations without disruption.
By leveraging AWS’s cloud infrastructure and machine learning services, United Airlines can build a cost-efficient OCR active learning pipeline. This pipeline enables them to process large volumes of documents accurately and quickly, improving operational efficiency and enhancing the customer experience.
The benefits of this cost-efficient OCR active learning pipeline are numerous. United Airlines can automate document processing tasks, reducing manual effort and human error. This leads to faster check-in processes, smoother boarding experiences, and improved overall efficiency.
Furthermore, the active learning component of the pipeline ensures continuous improvement of the OCR model over time. As more data is annotated and incorporated into the training process, the model becomes more accurate and reliable.
In conclusion, United Airlines’ collaboration with Amazon Web Services to build a cost-efficient OCR active learning pipeline demonstrates their commitment to leveraging cutting-edge technologies to enhance their operations. By automating document processing tasks and continuously improving their OCR model, United Airlines can provide a seamless travel experience for their passengers while optimizing costs and efficiency.
