How Vocational Education Got a 21st Century Reboot

#artificialintelligence

Erick Trickey is a writer in Boston. For a year, Rodriguez has worked 40-hour weeks as an apprentice test technician, examining IBM mainframes to confirm they work before shipping them to customers. In January, she'll move to a permanent position with a future salary that she says is "definitely much more than I ever thought I'd be making at 19." Rodriguez's opportunities with IBM came to her thanks to her high school, Newburgh Free Academy P-TECH. It's part of an innovative public-school model that combines grade 9-12 education with internships and tuition-free community college. P-TECH, which stands for Pathways in Technology Early College High School, has spread to 10 states and 17 countries since its founding in Brooklyn in 2011. The P-TECH network is growing fast.


ABOUT ML: Annotation and Benchmarking on Understanding and Transparency of Machine Learning Lifecycles

arXiv.org Machine Learning

We present the "Annotation and Benchmarking on Understanding and Transparency of Machine Learning Lifecycles" (ABOUT ML) project as an initiative to operationalize ML transparency and work towards a standard ML documentation practice. We make the case for the project's relevance and effectiveness in consolidating disparate efforts across a variety of stakeholders, as well as bringing in the perspectives of currently missing voices that will be valuable in shaping future conversations. We describe the details of the initiative and the gaps we hope this project will help address.


Graduate Employment Prediction with Bias

arXiv.org Machine Learning

The failure of landing a job for college students could cause serious social consequences such as drunkenness and suicide. In addition to academic performance, unconscious biases can become one key obstacle for hunting jobs for graduating students. Thus, it is necessary to understand these unconscious biases so that we can help these students at an early stage with more personalized intervention. In this paper, we develop a framework, i.e., MAYA (Multi-mAjor emploYment stAtus) to predict students' employment status while considering biases. The framework consists of four major components. Firstly, we solve the heterogeneity of student courses by embedding academic performance into a unified space. Then, we apply a generative adversarial network (GAN) to overcome the class imbalance problem. Thirdly, we adopt Long Short-Term Memory (LSTM) with a novel dropout mechanism to comprehensively capture sequential information among semesters. Finally, we design a bias-based regularization to capture the job market biases. We conduct extensive experiments on a large-scale educational dataset and the results demonstrate the effectiveness of our prediction framework.


Synthetic Datasets for Neural Program Synthesis

arXiv.org Artificial Intelligence

The goal of program synthesis is to automatically generate programs in a particular language from corresponding specifications, e.g. input-output behavior. Many current approaches achieve impressive results after training on randomly generated I/O examples in limited domain-specific languages (DSLs), as with string transformations in RobustFill. However, we empirically discover that applying test input generation techniques for languages with control flow and rich input space causes deep networks to generalize poorly to certain data distributions; to correct this, we propose a new methodology for controlling and evaluating the bias of synthetic data distributions over both programs and specifications. We demonstrate, using the Karel DSL and a small Calculator DSL, that training deep networks on these distributions leads to improved cross-distribution generalization performance.


How to Build a Meaningful Career in Data Science or AI

#artificialintelligence

Fast forward, I graduated and got an internship focusing on machine learning, where they offered me a full-time position in Data Science! This might be an extra scoop lol but I was part of an art program in high school, and when my journey in CS started, I feared I would lose that creativity in me. Luckily, I discovered as I got more into programming that my left and right side of the brain complement each other more and more, just as grapes and cheese do. What is the biggest achievement of your life till now? I am proud of not giving up even when things didn't look bright at all, not a single speck of light in the tunnel!

Learning Hybrid Representation by Robust Dictionary Learning in Factorized Compressed Space

arXiv.org Machine Learning

In this paper, we investigate the robust dictionary learning (DL) to discover the hybrid salient low-rank and sparse representation in a factorized compressed space. A Joint Robust Factorization and Projective Dictionary Learning (J-RFDL) model is presented. The setting of J-RFDL aims at improving the data representations by enhancing the robustness to outliers and noise in data, encoding the reconstruction error more accurately and obtaining hybrid salient coefficients with accurate reconstruction ability. Specifically, J-RFDL performs the robust representation by DL in a factorized compressed space to eliminate the negative effects of noise and outliers on the results, which can also make the DL process efficient. To make the encoding process robust to noise in data, J-RFDL clearly uses sparse L2, 1-norm that can potentially minimize the factorization and reconstruction errors jointly by forcing rows of the reconstruction errors to be zeros. To deliver salient coefficients with good structures to reconstruct given data well, J-RFDL imposes the joint low-rank and sparse constraints on the embedded coefficients with a synthesis dictionary. Based on the hybrid salient coefficients, we also extend J-RFDL for the joint classification and propose a discriminative J-RFDL model, which can improve the discriminating abilities of learnt coeffi-cients by minimizing the classification error jointly. Extensive experiments on public datasets demonstrate that our formulations can deliver superior performance over other state-of-the-art methods.


Academic Performance Estimation with Attention-based Graph Convolutional Networks

arXiv.org Artificial Intelligence

Student's academic performance prediction empowers educational technologies including academic trajectory and degree planning, course recommender systems, early warning and advising systems. Given a student's past data (such as grades in prior courses), the task of student's performance prediction is to predict a student's grades in future courses. Academic programs are structured in a way that prior courses lay the foundation for future courses. The knowledge required by courses is obtained by taking multiple prior courses, which exhibits complex relationships modeled by graph structures. Traditional methods for student's performance prediction usually neglect the underlying relationships between multiple courses; and how students acquire knowledge across them. In addition, traditional methods do not provide interpretation for predictions needed for decision making. In this work, we propose a novel attention-based graph convolutional networks model for student's performance prediction. We conduct extensive experiments on a real-world dataset obtained from a large public university. The experimental results show that our proposed model outperforms state-of-the-art approaches in terms of grade prediction. The proposed model also shows strong accuracy in identifying students who are at-risk of failing or dropping out so that timely intervention and feedback can be provided to the student.
