He believes that open source development can and will play a big part for many years to come and he likes to explore random new open source projects in his free time. One of his goals is to create a successful open source project.<\/p>\n\n\n\n Outside of programming, he likes to play board games and real-time strategy LAN games.<\/p>\n\n\n\n Demo: Testing Infrastructure for VowpalWabbit (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Several improvements can be proposed for the current approach to end-to-end testing in Vowpal Wabbit. The existing methodology generates expected output by executing the exact same command that is under evaluation, potentially introducing challenges to the robustness of the tests. Additionally, the current approach operates without assumptions about the nature of the data it is trained on. Furthermore, it lacks the capability to facilitate the implementation of tests using hyperparameter grids, which can result in increased implementation costs for Vowpal Wabbit.<\/p>\n\n\n\n To address these concerns, a new domain-specific language has been developed to facilitate the creation of end-to-end test configurations. This language includes support for defining hyperparameter grids, pluggable data stimulators and assertion functions, thereby enhancing the testing process.<\/p>\n\n\n\n Stelios Stavroulakis is a PhD student at the University of California, Irvine. For the past 5 years, he’s worked on reinforcement learning, focusing on applications in privacy, warehouse scheduling, and large language model hallucination control. His theoretical work is focused on exploring the intersection between reinforcement learning and game theory. Stelios has the ambition to incorporate his academic expertise to address a plethora of open problems in industry.<\/p>\n\n\n\n Demo:<\/strong> Optimizing In-Context Learning in LLMs (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Our project focused on improving the way large language models (LLMs) respond by choosing the right examples for in-context learning.<\/p>\n\n\n\n We addressed this by viewing it as a contextual bandit problem. By using a method called reduction to regression [1], we upper bound the regret of the contextual bandit algorithm by the performance of the regressor. Additionally, we utilized CappedIGW [2], ensuring our algorithm can handle a large action-space effectively. A standout feature is the regressor-agnostic nature of this method which allows the incorporation of powerful transformer models that excel in extracting semantic information from text. While we explored various techniques like bert and sentence transformers, progressive example fine-tuning (PEFT) emerged as the most promising approach.<\/p>\n\n\n\n In light of our preliminary findings, there’s clear promise in improving in-context learning via interaction. By decoupling prompt learning from the LLM, we pave the way for tailored personalization as well as striking a balance between computational expense and performance.<\/p>\n\n\n\n [1] Dylan J.

FlatBuffers is an efficient cross-platform serialization library for languages including C++, C#, C, Go, and Java. Improving flatbuffer parser support in VowpalWabbit will provide a new high-performance alternative to existing input data formats. This project focuses on improving the serialized size of the current flatbuffer format and measuring performance.<\/p>\n\n\n\n Ivoline is a 2nd-year Ph.D. student in Computer Science at the University of Vermont and a research scientist at OpenMined. Her research interests broadly revolve around all aspects of machine learning; theory, algorithms, and applications. Currently, she focuses on provable fairness and privacy-preserving machine learning including differential privacy, federated learning, and secure multiparty computation. She can usually be found in the kitchen whipping up a savory meal or getting lost in the plot of a good book when she\u2019s not working. <\/p>\n\n\n\n Demo: Compiler Optimizations using Reinforcement Learning (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Expert-picked sequences are used in compilers to optimize performance for the conversion of human-written programs into executable binaries. These heuristics are developed by experts who spend hours tweaking compiler knobs resulting in smaller and faster binaries. By replacing these complex heuristics with reinforcement learning(RL) policies, we aim to enable compilers to automatically optimize code without using prefixed parameters or predefined ordering. Specifically, we try to tackle the phase-ordering problem, performing code size and runtime reduction in the LLVM compiler using RL environments, intermediate representations, and datasets provided by CompilerGym. Integrating the gym environment with Vowpal Wabbit RL agents like contextual bandits, we are able to obtain code size reductions. Furthermore, benchmarking the performance of different deep learning-based RL agents, as well as experiments in different observation spaces, shows promising results. Future work can focus on improving datasets and observation features to make them more representative as well as developing better reinforcement learning agents.<\/p>\n\n\n\n Shaokun Zhang is a first-year Ph.D. student in the College of Information Sciences and Technology at Pennsylvania State University. His primary research interests are automatic machine learning. Currently, his research has a special focus on AutoML in the data stream setting. He has contributed to several open-source projects such as AutoML library FLAML at Microsoft Research. Shaokun is passionate about doing research and coding.

Outside of work, he loves traveling, reading, and running. <\/p>\n\n\n\n Demo: Automl Extensions (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n In machine learning, AutoML is the process of applying machine learning (ML) models to real-world problems using automation. It automates the selection, composition, and parameterization of machine learning models. It aims to allow non-experts to make use of machine learning models and free people from repeated work of model development. As for VW, the target of AutoML reduction is to provide users with a hands-off method to get an optimal learning configuration without prior experience using VW or an in-depth understanding of their dataset. A “configuration” is the basic element of AutoML and a general term that can be extended to any aspect of VW. We defined it as a set of namespace interactions in a contextual bandit problem. However, VW only supports quadratics interaction in AutoML reduction, which greatly limited the application scope and feature richness. We rewrite the data structures of configuration in VW. In this way, it will support storing interactions of arbitrary size and provide a more flexible interface for future development. We also design a mechanism that extends AutoML to add and drop cubic interactions. It will greatly enlarge the search space and expands the application scope of the AutoML algorithm.<\/p>\n\n\n\n Songlin Jiang is from China and recently (2022 Summer) completed his bachelor’s degree in specialized class for fundamentals and theories of Computer Science and Technology (Hons) at Lanzhou University.

He is a member of the openSUSE for his continuous contribution during and after Google Summer of Code 2021. Distributed machine learning and related security issues are Songlin’s research interests. As Moore’s Law is starting to fail, he believes that distributed systems will be the future infrastructure to support the growing need for computing power in machine learning. <\/p>\n\n\n\n Demo: Native CSV parsing (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Our project introduces a native CSV parser (opens in new tab)<\/span><\/a> making VW recognize the CSV format. The parser follows the RFC 4180 and MIME standards, with specifications of CSV header format adapting to VW training and prediction needs. Our project reaches 100% test and code coverage, and the parsing performance is comparable to the VW format parser. We also write a tutorial for using the CSV parser. Here are the design details: <\/p>\n\n\n\n Because alternative delimiter-separated files are often given a `.csv` extension despite using a non-comma field separator, the parser allows specifying the CSV field separator. In addition, we always need a CSV header to work correctly. If the header doesn’t exist or suit VW parsing needs, we can tell the parser the correct one with command line options. In this case, users do not need to edit the dataset after downloading it from the Internet. <\/p>\n\n\n\n For the format of the headers, we use `_label` and `_tag` to mark the label and tag column and `|` to separate the other column’s namespace and feature name. To ensure there will always be an equivalent CSV file for VW format files, we make the label data format the same as the VW labels’. The parser also supports scaling the namespace values by specifying the ratio in command line options. Since multi-line examples often mean different lines have different schemas, CSV is unsuitable for them. However, suppose all the cells in a line are empty, we will still mark it as a new line. In this case, users can still express multi-line examples in CSV files, although it is not listed as supported.<\/p>\n\n\n\n Muhammad Ammar Abid (opens in new tab)<\/span><\/a> is a senior year undergraduate at NUCES (FAST) Peshawar campus in Pakistan.

Ammar\u2019s future priority is to end up at a diverse and inclusive place where his collaboration can solve real world problems while empowering people in the process.<\/p>\n\n\n\n Demo: Tensorboard and Tensorwatch Integration (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Visualization is necessary for brain to process large information. Tensorboard provides visualization and tooling necessary which can be effectively used for machine learning experimentation. Integrated in the Vowpal Wabbit ecosystem, this could help the users to focus more on the problem and extract meaningful results with help of visualization. Currently, we have extended the Vowpal Wabbit Python bindings to support outputting progress updates and model details to Tensorboard.<\/p>\n\n\n\n Wilson Cheung recently completed his M.S. in Analytics from Georgia Institute of Technology. He previously worked as a data scientist at Booz Allen Hamilton where he developed many artificial intelligence and data engineering capabilities to address technological problems faced by government clients in healthcare and defense industries. He currently works as a data scientist at Amazon Web Services and is hoping to develop his professional career towards AI-based personalization using reinforcement learning and bandit-based methods learned in the participation of RLOS.<\/p>\n\n\n\n Demo: Extend FairLearn to include RL bias analysis using VW (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Analyzing outcomes of a learned policy in an online setting through contextual bandits poses many unforeseen consequences in the study of responsible AI. Particularly, given that the objective for many RL systems is to maximize accumulated rewards, any policy can potentially carry latent harms throughout the online evaluation process. By using logged contextual bandits data generated via Vowpal Wabbit under an assumed logged policy, we compute FairLearn-supported fairness metrics to identify these harms and use counterfactual analysis to assess the quality of evaluation policies. Lastly, we identify ways to mitigate the impacts of these harms under the reduced weighted multi-class classification setting.<\/p>\n\n\n\n M\u00f3nika Farsang is from Budapest, Hungary.

However, there are many safety-critical domains where this kind of behavior is undesirable. Consequently, our goal is to implement safe contextual bandits which focus specifically on the worst cases. To achieve this, we use conditional value at risk (CVaR), which means the expected return in the worst q% of the cases. By using this, we optimize the average of the tail instead of the average of the whole distribution to maintain safety and avoid choosing bad actions. CVaR has a dual representation mathematically, which results in off-policy learning with passing modified rewards to the contextual bandit. By leveraging this formulation, we optimize the cut-off value of the distribution online. To optimize the cut-off point, we use a no-regret algorithm called FreeGrad, which is practical because it does not contain any hyperparameter tuning. The results of our project demonstrate that better worst-case behavior can be achieved by optimizing the CVaR of the distribution compared to typical contextual bandit policies.<\/p>\n\n\n\n Nishant is currently pursuing his bachelor\u2019s in Electronics Engineering from the Indian Institute of Technology (BHU), Varanasi, India.

However, VW\u2019s parsers can be a bottleneck for most operations, so an effective way to multithread the parsers is required to unleash their true potential. Last year, parallel parsing support for text input format was provided. This project builds upon that by providing a better and more efficient way to read and write cache, support for multiple passes, multiline examples, and JSON\/DsJSON input formats.<\/p>\n\n\n\n Milena Mathew is an undergraduate majoring in Electrical Engineering and Computer Science at UC Berkeley. She\u2019s broadly interested in the intersection of computer science and physics and has previously worked on applying machine learning techniques to problems in the natural sciences. After graduating, Milena hopes to work in industrial R&D. In her free time, you can typically find her tackling the latest crossword or baking a batch of cookies.<\/p>\n\n\n\n Demo: Safe Contextual Bandits (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Contextual bandit algorithms are typically designed to maximize the expected reward over time. However, in systems where there\u2019s a safety constraint, avoiding bad actions may be valued over purely maximizing reward. We aim to account for both of these goals by developing a chance-constrained policy optimizing learner. Chance constrained policy optimization takes advantage of additional observed feedback to determine the probability of a decision violating a constraint while still optimizing for reward. We implemented the learner in Coba- a contextual bandit algorithm benchmarking application- and added functionality to accommodate multiple observations. We aim to show the feasibility of this approach by comparing the amount of constraint-violating behavior in our learner versus traditional contextual bandit algorithms.<\/p>\n\n\n\n Krystal Maughan is from Trinidad and Tobago.

Computer Science and MSc. Economics from BITS Pilani. Her current research interests involve Artificial intelligence, Federated Learning, Algorithmic Game theory and Optimization. She has worked on projects at the intersection of Reinforcement Learning, NLP and Information retrieval.

The current prototype of the estimator library lacked a clear structure, which made it hard to install and consume. Moreover, for researchers to contribute by adding new estimators, it is imperative for them to know which interfaces to use according to their problem type(cb, ccb, slates, ca, etc). Therefore, as a part of this project, we added interfaces for each problem type, worked on CI improvements, added new estimators, added tests, structured the estimator library and finally released it to PyPI as vw-estimators. Our work will capacitate the estimator library to be consumed by AML pipeline and end-users.<\/p>\n\n\n\n Manav Singhal is a senior year undergraduate student at the National Institute of Technology Karnataka, India studying Electrical and Electronics Engineering. His current research interests lie in improving the deployment of reinforcement learning in real-world scenarios and increasing the interpretability of machine learning models.

After graduating, he wishes to pursue his graduate studies in Computer Science.<\/p>\n\n\n\n Demo: Empirical Analysis of Privacy Preserving Learning (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n In many real-world learning scenarios, due to privacy constraints (for example, General Data Protection Regulation), one cannot use the user feature mapping directly for personalization. In order to uphold the privacy of the user, we aim to study the effect of using aggregated data for learning. We explore the notion of \u201caggregation\u201d by saving only those features after training that have crossed a certain threshold of users. This project focuses on comparing the performance of the model without aggregation (public model) and the model with aggregation (private model), thus understanding how much this filtering helps in the learning process.<\/p>\n\n\n\n Varun Suryan grew up in northern India.

This is crucial in online learning services which can significantly benefit from online autoML style algorithms to automatically choose hyperparameters\/configs. Currently, most of the tuning is done manually. This problem has been studied before under the full information (supervised) setting where each configuration has access to the revealed feedback from the environment. However, bandits present unique challenges, and not every configuration gets to receive feedback from the environment. By using importance weight to update the loss bounds for a subset of configurations, ChaChaCB performs competitively with several baselines. Further, we plan to integrate ChaChaCB as a learner in Coba \u2013 a standardized framework to test contextual bandit learners.<\/p>\n\n\n\n Vishal Vinod (opens in new tab)<\/span><\/a> is a Computer Science master\u2019s student at University of California, San Diego.

Apart from research, he is involved in the open-source community and reads up on developmental economics.<\/p>\n\n\n\n Demo: VW feature transformation without redeploying the source (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Feature transformation are necessary to prototype, mutate or compare the performance of a trained model. Currently, creating a feature mutation in VW requires the implementation of a new C++ reduction for each mutation, making it harder to work on new ones. This project simplifies feature modifications by implementing a generic reduction such that example modification functions can be registered with the interface and used without having to implement a reduction for each transformation. This allows mutation functions such as deleting a feature, dropout, normalization, logarithmic mutation, feature binarization, etc. to be registered on the stack for the model in memory without redeploying the source. The generic reduction enables feature engineering pipelines using only callable functions to modify the example, and also allows comparing the performance of models with and without mutations in a single run for benchmarking and avoids the step of transforming the data by other means.<\/p>\n\n\n\n Milind Agarwal (opens in new tab)<\/span><\/a> is a combined undergraduate and master\u2019s student in Computer Science at Johns Hopkins University.

Visualizations not only allow you to kickstart your analysis by easily understanding the patterns in your data but also help you visually inspect your policies to understand their behaviour. We present cb_visualize, a python-based visualization library specialized for contextual bandits features and policy visualizations. This library offers robust visualizations for data exploration, training, feature importance, and action distributions and supports common contextual-bandit dataset formats used by Vowpal Wabbit like text, JSON, and DSJSON. We hope that this toolkit will be an asset for researchers and customers alike to better present and understand their data and analyses.<\/p>\n\n\n\n Sharad Chitlangia (opens in new tab)<\/span><\/a> is a senior year undergraduate student at BITS Pilani Goa, where I studied Electronics.

Through this project, we aim to take this ability, even further, by the introduction of Flatbuffers. Flatbuffers is an efficient cross-platform serialization library known for its memory access efficiency and speed. We develop Flatbuffer schemas, for input examples, to be able to store them as binary buffers and show a performance increase of 30%, or more compared to traditional formats.<\/p>\n\n\n\n Harish Kamath (opens in new tab)<\/span><\/a> is a Computer Science\/Math undergraduate at Georgia Tech.

It describes a model as a computational graph consisting of a set of standard operators from an operator set that is constantly evolving to accommodate new types of models and operations. Being able to describe a model in ONNX format is important, as it allows for (1) models to be optimized and run across different architectures using a single runtime, and (2) it allows models created in different frameworks to interact with each other. Although other leading frameworks such as Tensorflow and Pytorch have mature tools to convert into ONNX format, VowpalWabbit today does not yet have the capability baked into the framework. This project focuses on introducing this functionality to VowpalWabbit, so that we can combine the fast model training and inference speed of VW with the representational capacity of other frameworks. We introduce new sparse operators that are used to instantiate VW regression models efficiently in ONNX format, show that you can directly translate regression and contextual bandits models with these operators, and give an example of such models being run in RLClientLib to show that they can now be ported into any inference framework.<\/p>\n\n\n\n Cassandra Marcussen (opens in new tab)<\/span><\/a> is a junior at Columbia University studying Mathematics and Computer Science.

Currently, VW uses a single thread to read in and parse input, and a single thread to learn. The parse thread presents a bottleneck, slowing down VW as a whole. By extracting the input reading into a separate thread and extending the parser to support many threads, VW can better utilize resources, achieve better performance, and have an improved design by separating logical components into independent modules. This project focuses on improving performance and design for the text input format, and also ensures compatibility with the cache input format.<\/p>\n\n\n\n Newton Mwai Kinyanjui (opens in new tab)<\/span><\/a> is from Nairobi Kenya.

One common estimator is IPS, and others are DR and PseudoInverse. These estimators work better or worse in different settings.

We extend the estimators library and implement an interface to help researchers and data scientists test different estimators quickly and easily.<\/p>\n\n\n\n Mark Rucker (opens in new tab)<\/span><\/a> is currently a 2nd year PhD student at the University of Virginia with a previous 8-year career as an enterprise software engineer. Mark\u2019s PhD research explores how reinforcement learning models can be used to encourage health behavior change in individuals managing chronic health conditions. This research combines state of the art machine learning with web and mobile app development to support in-situ randomized control trials of behavior change interventions. After graduation Mark hopes to once again return to industry in order to develop high-quality products that deeply impact people\u2019s lives.<\/p>\n\n\n\n Demo: Challenge: COBA: A Modern Benchmarking Package for Reproducible Contextual Bandit Research (opens in new tab)<\/span><\/a><\/strong><\/p>\n\n\n\n Performance benchmarking on well-defined problems is a pillar of modern machine learning research. With clear problems and metrics, benchmarking has allowed the research community to maintain a high-level of independent effort while still making real and meaningful progress over time. The elegance of benchmarking \u2014 define, measure, repeat \u2014 however, belies real engineering challenges such as software maintenance, data distribution, statistical aggregation, and reproducibility to name a few. These challenges are especially salient in contextual bandit research where one not only needs a data set but also a harness to emulate interaction with the data. In an effort to reduce these burdens, while not losing any of benchmarking\u2019s benefits, we present COBA, an ultra light-weight Python package for benchmarking contextual bandit algorithms. COBA uses a small set of clean and consistent interfaces to satisfy four core use cases: (1) creating reproducible benchmarks, (2) sharing reproducible benchmarks, (3) evaluating custom algorithms, and (4) exploring evaluation results.<\/p>\n\n\n\n No. RL Open Source Fest is an activity that the student performs as an independent developer in collaboration with the real world reinforcement learning team at Microsoft Research, for which they are paid a stipend.<\/p>\n\n\n\n\n\n Yes.

What makes a successful project?<\/h2>\r\nSuccess looks different for every project. Challenging yourself and developing skills and knowledge are the most important part. Producing some sort of deliverable item is great, but not strictly required. We all know how development and experimentation goes, unforeseen\u00a0problems can come up and present new challenges and that's all part of the process. You'll have a mentor and support along the way.\r\n
