WHAT ARE SOME COMMON CHALLENGES FACED DURING THE DEVELOPMENT OF DEEP LEARNING CAPSTONE PROJECTS

Leave a reply

One of the biggest challenges is obtaining a large amount of high-quality labeled data for training deep learning models. Deep learning algorithms require vast amounts of data, often in the range of millions or billions of samples, in order to learn meaningful patterns and generalize well to new examples. Collecting and labeling large datasets can be an extremely time-consuming and expensive process, sometimes requiring human experts and annotators. The quality and completeness of the data labels is also important. Noise or ambiguity in the labels can negatively impact a model’s performance.

Securing adequate computing resources for training complex deep learning models can pose difficulties. Training large state-of-the-art models from scratch requires high-performance GPUs or GPU clusters to achieve reasonable training times. This level of hardware can be costly, and may not always be accessible to students or those without industry backing. Alternatives like cloud-based GPU instances or smaller models/datasets have to be considered. Organizing and managing distributed training across multiple machines also introduces technical challenges.

Choosing the right deep learning architecture and techniques for the given problem/domain is not always straightforward. There are many different model types (CNNs, RNNs, Transformers etc.), optimization algorithms, regularization methods and hyperparameters to experiment with. Picking the most suitable approach requires a thorough understanding of the problem as well as deep learning best practices. Significant trial-and-error may be needed during development. Transfer learning from pretrained models helps but requires domain expertise.

Overfitting, where models perform very well on the training data but fail to generalize, is a common issue due to limited data. Regularization methods and techniques like dropout, batch normalization, early stopping, data augmentation must be carefully applied and tuned. Detecting and addressing overfitting risks requiring analysis of validation/test metrics vs training metrics over multiple experiments.

Evaluating and interpreting deep learning models can be non-trivial, especially for complex tasks. Traditional machine learning metrics like accuracy may not fully capture performance. Domain-specific evaluation protocols have to be followed. Understanding feature representations and decision boundaries learned by the models helps debugging but is challenging. Bias and fairness issues also require attention depending on the application domain.

Integrating deep learning models into applications and production environments involves additional non-technical challenges. Aspects like model deployment, data/security integration, ensuring responsiveness under load, continuous monitoring, documentation and versioning, assisting non-technical users require soft skills and a software engineering mindset on top of ML expertise. Agreeing on success criteria with stakeholders and reporting results is another task.

Documentation of the entire project from data collection to model architecture to training process to evaluation takes meticulous effort. This not only helps future work but is essential in capstone reports/theses to gain appropriate credit. A clear articulation of limitations, assumptions, future work is needed along with code/result reproducibility. Adhering to research standards of ethical AI and data privacy principles is also important.

While deep learning libraries and frameworks help development, they require proficiency which takes time to gain. Troubleshooting platform/library specific bugs introduces delays. Software engineering best practices around modularity, testing, configuration management become critical as projects grow in scope and complexity. Adhering to strict schedules in academic capstones with the above technical challenges can be stressful. Deep learning projects involve an interdisciplinary skillset beyond conventional disciplines.

Deep learning capstone projects, while providing valuable hands-on experience, can pose significant challenges in areas like data acquisition and labeling, computing resource requirements, model architecture selection, overfitting avoidance, performance evaluation, productionizing models, software engineering practices, documentation and communication of results while following research standards and schedules. Careful planning, experimentation, and holistic consideration of non-technical aspects is needed to successfully complete such ambitious deep learning projects.

HOW ARE CAPSTONE PROJECTS AT GREAT LEARNING GRADED AND EVALUATED

Leave a reply

Great Learning takes the capstone project very seriously as it is meant to assess the student’s mastery of concepts learnt throughout their program. The capstone acts as a culminating experience where students work on real-world projects to solve meaningful problems. It allows students to integrate and apply their learnings to complex, open-ended problems with the guidance of both an industry mentor and an academic mentor.

The grading and evaluation of capstone projects is a rigorous process to ensure fairness and obtain reliable assessment. Each capstone project undergoes a multi-stage evaluation process involving specific rubrics, mentor feedback, and assessments from multiple reviewers.

The first step is for students to submit a capstone proposal detailing the problem statement, objectives, approach, timeline, and evaluation criteria. This proposal is reviewed by the academic mentor to provide feedback and approve the direction of the project. Students are expected to incorporate the feedback to refine their proposal.

Once the proposal is approved, students begin working on their capstone under the guidance of their assigned industry and academic mentors. Mentors play a crucial role in the evaluation process by providing regular feedback and guidance to students. Every 1-2 weeks, mentors review the students’ progress and provide feedback. This ensures students are on the right track as per the timelines and problem definition. Mid-way through the capstone, students have a checkpoint meeting with their mentors where deeper discussions are held on the approach, learnings, challenges and next steps.

Towards the end of the capstone duration, students are required to submit a complete project report and presentation. The report should document everything – problem definition, literature review, methodology, implementation, results, conclusions and future work. Multimedia artifacts developed as part of the capstone like code, models, prototypes etc. should also be submitted.

Detailed rubrics are used to evaluate different aspects of the capstone work like problem definition, literature survey, approach, implementation, analysis, outcomes, report structure, presentation etc. Rubrics assess students based on criteria like clarity, depth, innovation, integration of concepts, real-world applicability, quality of output etc. Using well-defined rubrics ensure fairness and consistency in grading.

Once submitted, the capstone work goes through a rigorous multi-stage evaluation process. In the first stage, the industry mentor evaluates the project based on the rubrics and provides a detailed feedback and preliminary scores. In the second stage, the academic mentor also evaluates the project independently based on the rubrics.

In the third stage, the project undergoes a final evaluation by a panel of 2-3 expert evaluators drawn from both industry and academia. The panel members are experienced professionals and academicians with deep expertise in the domain area of the capstone project. They thoroughly assess the project documentation, presentation, artifacts, mentor feedback letters and use their expertise to gauge the quality, depth and applicability of the work. The panel members discuss their evaluations together and come to a consensus on the final scores.

The preliminary scores from the mentors and the final scores from the expert panel are averaged out to compute the final grades for the capstone. Students must score a minimum aggregate of 60% to pass. For borderline cases or disagreements, an additional assessment by the program chair is carried out. Detailed scorecards and feedback letters are shared with students highlighting strengths, areas of improvement and lessons learnt from their capstone journey. Students who fail may be asked to re-do portions of their work based on feedback.

This rigorous, multi-stage grading process involving mentors, subject experts and program leaders helps ensure capstone projects at Great Learning are evaluated fairly and reliably. The well-defined rubrics and involvement of industry and academic experts in evaluation also helps assess real-world applicability and depth of learning achieved through the project. The process aims to equip students with the necessary skills through hands-on learning to tackle complex challenges through a blended approach of theory and practice.

Capstones offer invaluable opportunities to practice and further develop the wide range of skills crucial for navigating diverse real estate career paths.

WHAT ARE SOME COMMON CHALLENGES IN EVALUATING CAPSTONE PROJECTS

Leave a reply

One of the primary challenges in evaluating capstone projects is determining clear and consistent evaluation criteria. It is important to establish goals and learning outcomes for the capstone experience and align the evaluation criteria directly to those outcomes. This ensures students understand what is expected of their project from the beginning and provides guidance for the evaluation. Specific criteria should be established for areas like the quality of research, critical thinking demonstrated, technical skills applied, presentation effectiveness, and written work. Rubrics are very helpful for breaking down the criteria into detailed levels of achievement.

Another challenge is subjectivity in scoring. Even with clear criteria, different evaluators may weigh certain aspects of a project differently based on their own preferences and backgrounds. To address this, it is best to have multiple evaluators review each project when possible. Scores can then be averaged or discussed to reach consensus. Implementing calibration sessions where evaluators jointly review sample projects using the criteria and compare scoring can also help produce more consistent and objective evaluations.

The scope and complexity of capstone projects can vary widely between students, which presents a challenge for direct comparisons. Some approaches to help mitigate this include providing students with guidance on setting an appropriate scope for their level of experience and access to resources. Evaluators should also consider the scope when assessing if the project met its stated objectives and challenge level. Allowing for flexibility in project types across disciplines also better accommodates different areas of study.

Clearly communicating expectations to students throughout the capstone experience is necessary to conduct fair evaluations. This includes providing guidelines for acceptable deliverables at each stage, facilitating regular check-ins and feedback, and establishing due dates for draft submissions and final project presentation/documentation. Unexpected technical issues, personal struggles, or other real-world constraints students face are more reasonably accommodated when communication has been proactive.

Evaluating the problem-solving process as heavily as the final output can also help account for challenges encountered. Students should document decisions made, alternatives explored, dead-ends faced, and how problems were addressed. Evaluators can then assess the critical thinking, research, and iterative design process involved rather than just the end product. This evaluates learning and skill-building even if final technical successes and goals were not fully achieved.

Understanding the learning environment and context of each student’s experiences outside the academic setting is another important factor. Juggling capstone work with jobs, families, health issues and more can differentially impact progress and outcomes. While evaluations should maintain standards, they can account for individual circumstances through student narratives and considering non-academic demands on their time and stress levels.

Assessing communication and presentation abilities poses challenges due to variables like comfort with public speaking or writing style that are not fully within students’ control. Using uniform presentation formats, providing practice opportunities and focused feedback, judging content over delivery mechanics, and allowing various outlet options (reports, demonstrations, etc.) can help address inherent differences in soft skills.

Synthesizing feedback from multiple evaluators, artifacts from the entire design/research process, student reflections and circumstances into final scores or grades requires significant effort. Developing evaluation rubrics with distinct criteria, anchoring descriptions for achievement levels, calibration among reviewers, and documenting decisions can help produce consensus, consistency and defendable final assessments of capstone work and the learning that occurred.

With thorough planning, clear guidance provided to students, multi-faceted criteria focusing on process as well as products, consideration of individual situations and calibrations to mitigate subjectivities – capstone evaluations can successfully, fairly and reliably assess the overarching goals of demonstrating subject mastery and transferrable skills. While challenges will always exist with high-stakes culminating projects, following best practices in evaluation design and implementation can optimize the learning outcomes.

CAN YOU PROVIDE MORE EXAMPLES OF EVIDENCE BASED PRACTICE PROJECTS FOR A NURSING CAPSTONE

Leave a reply

Implementing a skin bundle to reduce hospital-acquired pressure injuries. Pressure injuries are preventable harms that patients can experience in the hospital. For this project, the student would conduct a literature review on best practices for preventing pressure injuries. This would include interventions like performing regular risk assessments, improving nutrition, turning schedules, special mattresses/overlays, and keeping the skin clean and dry. The student would then develop a “skin bundle” or checklist of all the recommended interventions. They would educate nursing staff on the bundle and its importance. Outcome measures would track if pressure injury rates decreased after fully implementing the skin bundle.

Standardizing shift-to-shift nurse handoffs to improve patient safety and outcomes. Handoff communication between nurses is crucial but often informal and inconsistent. This can lead to lapses in care or patient information being missed. For this project, the student would research the components of an effective nurse handoff based on evidence-based guidelines. They would then develop a standardized handoff tool or format to be used at every shift change. Examples of components to include are patient name, pertinent assessment findings, cares completed since last handoff, outstanding tasks, questions or concerns, plan for upcoming shift. Compliance with the handoff tool would need to be monitored. Outcome measures could examine factors like medication errors, patient satisfaction, call light usage after implementation to see if standardizing handoffs made any difference.

Reducing hospital readmissions amongst heart failure patients through a post-discharge support program. Readmissions, especially within 30 days of discharge, are costly to the healthcare system and can be a sign of gaps in transitional care. For this project, the student would complete a literature review on evidence-based interventions shown to reduce readmissions in heart failure patients. This may include scheduling follow up clinic visits before discharge, patient education on medication management and diet, ensuring patients have devices to monitor weight and symptoms at home. The student would then design and implement a post-discharge support program incorporating these interventions. Outcome data could be collected on readmission rates pre- and post- implementation of the program to see if it made a significant impact. Patient surveys may also provide insight on the program’s effectiveness.

Increasing influenza vaccination rates amongst healthcare staff through an educational campaign. Healthcare workers with direct patient contact should receive the annual flu shot to prevent spreading influenza to vulnerable patients. Vaccination rates often fall short of goals. For this project, the student would analyze reasons for low compliance based on staff surveys. They would then develop an educational campaign highlighting the importance of flu shots from an evidence-based perspective. Example strategies could be flyers, emails with facts, posters in break rooms, in-services for staff. Compliance would need to be closely monitored before, during and after the campaign. If vaccination rates showed an improvement post-intervention, it would provide evidence the educational efforts were successful.

The key factors all these capstone projects have in common are:

Drawing from current literature and evidence-based guidelines to identify clinical problems/ gaps and best practices for improving care.

Developing well-planned, systematic interventions tailored to the clinical setting and informed by research.

Implementing the intervention(s) over a dedicated time frame while monitoring compliance and collecting appropriate pre and post outcome data.

Analyzing results statistically to determine if the evidence-based changes significantly improved the identified outcomes.

Formally reporting the project findings, limitations, and recommendations in a written paper and oral presentation.

By following this general structure, nursing students can develop meaningful evidence-based practice projects that have the potential to positively impact patient care and outcomes. The projects also allow students to gain experience planning, implementing and evaluating a quality improvement effort – important skills for any nurse.
