  • [Project] Open Source Stock/Crypto Monitoring Dashboard With Twitter/Reddit Sentiment Analysis
    by /u/GabrielMusat (Machine Learning) on May 26, 2022 at 5:17 pm

    The need for information regarding the economy and the current state of the stock market has been my main motivation in the development of this project. https://preview.redd.it/8atsbe6ssu191.png?width=3442&format=png&auto=webp&s=a91abce216f409988b81a143d56cdfdafd923e58 Right now it's able to retrieve useful market data in real time from the yahoo finance API, most recent market related tweets from Twitter API, and recent posts from Reddit using the Reddit API. It uses VADER sentiment analysis on tweets and Reddit posts in order to extract and display sentiment evolution across time. https://github.com/GabrielMusat/market-monitor The project is conceived to be extended with new metric collection plugins, which is something very easy to accomplish as there is no frontend development involved (that UI is not even mine, it's from InfluxDB, a great open source time-series database with built-in dashboard creation tools) This decision comes from the fact that I am not an expert in either AI or stock/crypto trading, but people that are can contribute with their knowledge without the pain of managing a time-series database or developing a UI. I am thinking of something like: AI powered technical analysis NLP applied to market news RL based buy/hold/sell suggestions For those of you who are trying to stay informed about the state of the market, I hope this tool can be useful to you as it has been to me.

  • [D] How can we approach this problem ?
    by /u/corporatededmeat (Machine Learning) on May 26, 2022 at 12:34 pm

    You have a combined dataset consisting of 10 component datasets collected from 10 different sources. Independent models trained separately on each component dataset perform well on hold-out examples from that dataset. However, the aggregated model trained by combining the examples from all component datasets behaves weirdly. On hold-out examples from some component datasets, the aggregated model performs better than the independent models. On others, it performs worse than the independent models. During deployment, you expect to see input examples from these 10 component sources but also from many other sources which the model has not been trained on. What approach will you take to develop a model that will generalize well to examples from the seen and also the yet-unseen sources? submitted by /u/corporatededmeat [link] [comments]

  • [R] New datasets for StyleGAN
    by /u/RonMokady (Machine Learning) on May 26, 2022 at 12:06 pm

    Hi all, The Author is here. TL;DR: We show how StyleGAN can be adapted to raw unaligned images collected from the Internet. New datasets and models are available. ​ How can we adapt StyleGAN to more complicated datasets? We have witnessed that a data-centric approach is the most effective. Raw image collections downloaded from the internet contain many outlier images and are characterized by a multi-modal distribution. Therefore, we perform automatic self-supervised filtering of the training data to remove the outliers. Our key idea is to use the generator itself for the filtering. In the second step, we employ a multi-modal variant of the StyleGAN truncation trick. This allows high quality generation while preserving the remarkable editing capabilities of StyleGAN. For more details and cool gifs, check our Project Page:https://self-distilled-stylegan.github.io/ Datasets and models: https://github.com/self-distilled-stylegan/self-distilled-internet-photos The datasets also can be directly downloaded: https://github.com/rmokady/SDIP_utils Demo for image generation: https://huggingface.co/spaces/hysts/Self-Distilled-StyleGAN ​ Feel free to ask anything that comes to your mind ​ Generated Dog Generated Elephant submitted by /u/RonMokady [link] [comments]

    Hey, it's Merve from Hugging Face 👋 I wanted to share some big news that I hope you find useful. The 🤗 Hub now has pull requests (PR) and discussions in repositories to improve collaboration in machine learning 🥳✨ What does PR really mean here? Let’s assume you have a big PyTorch model and someone else ported it to TensorFlow, that person can contribute that to your model repository. Someone else can open a PR to improve your model, fix your machine learning demo in a Space or change anything in the dataset. This applies for model/Space/dataset (any repo) repositories on the hub. You might say this sounds familiar to GitHub. For code, GitHub works super well and we don’t want to (and it would be very inefficient to) recreate the feature set of GitHub. What we want to focus on is creating the collaboration toolset that’s optimized for ML. You can learn more about these new features here: https://huggingface.co/blog/community-update. Looking forward to your feedback and suggestions! ✨ Hope this is useful 🙂 submitted by /u/unofficialmerve [link] [comments]

  • [D] PyTorch processes taking up tons of GPU memory - any way to reduce this?
    by /u/tmuxed (Machine Learning) on May 25, 2022 at 4:41 pm

    I am running on Arch Linux 5.17.9-arch1-1 with an NVIDIA GeForce RTX 3090 GPU. I need to run multiple processes for a reinforcement learning task, where each subprocess runs the data collection (and inference) and all the samples from that are then retrieved via queues in the main process and optimized (e.g. think of PPO but distributed, like IMPALA). I am using torch.multiprocessing for this. Unfortunately, the multiple spawned subprocesses cause A LOT of overhead in terms of GPU memory being used. See below for my nvidia-smi output: | 0 N/A N/A 559025 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559026 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559027 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559028 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559029 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559030 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559031 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559032 C ...3/envs/ml/bin/python 1873MiB | | 0 N/A N/A 559033 C ...3/envs/ml/bin/python 1873MiB | So it seems like each subprocess loads the entirety of all of PyTorch into GPU memory, which seems incredibly inefficient. Is there a way to get the subprocesses to only load this once and then share it? How can I reduce the GPU footprint for each process? EDIT: Even using a basic example from the PyTorch repo I can see the same problem: Because it's not forking, it seems to be using up tons of GPU memory for each process. Can this not be fixed? submitted by /u/tmuxed [link] [comments]

  • [P] ZenML: Build vendor-agnostic, production-ready MLOps pipelines
    by /u/htahir1 (Machine Learning) on May 25, 2022 at 4:32 pm

    Hello r/MachineLearning! Some here might remember we open-sourced ZenML, a year or so ago, and started building it out in the open. Today, we're re-launching it to the world, with a brand-new look, and a sharper focus. We've spoken to hundreds of ML teams in the last year, and here is what we've found: 🐘 Getting ML into production reliably is still hard today. It takes too long, is too complicated, and not enough people know how to do it. 🦡 MLOps platforms are not the answer because they are opinionated, rigid, and slow to change. It's time for MLOps frameworks to shine, and bring structure to the ML ecosystem that is ripe for standardization. 🐼 Well-thought-out abstractions that make sense and are flexible are what the industry needs. Our launch blog post, "The Framework Way is the Best Way", goes into further detail on this. ZenML is a framework 🖼️, not a platform 🚉 , which standardizes your MLOps pipelines. With ZenML, we enable developers of all backgrounds by providing a vendor-agnostic, open-source MLOps solution that’s easy to plug into and just works. Here's how it works: Define Pipelines and Steps Define steps and pipelines in a simple SDK At the heart of ZenML, you will find our pipelines. These pipelines provide a simple interface for you to design your ML workflows in a portable and production-ready manner. Each pipeline consists of several steps, which ingest and generate artifacts. You can design these pipelines and steps using a simple Python SDK. Configure Infrastructure Via Stacks Define infrastructure configuration in a code-agnostic way via Stacks To execute these pipelines we need to use a ZenML Stack. A stack represents the configuration of your infrastructure and consists of several stand-alone components. Three components are essential to each stack. An artifact store, where you store the input and output artifacts of your steps, a metadata store, where your executions are tracked and an orchestrator, which conducts the execution of pipeline and steps. You can also add additional components to your stacks, such as experiment trackers, secret managers, model deployers, and more. One of the most important traits about the stack is that it is completely separated from your step and pipeline code. This means if you want to move from a local setup to a remote setup all you need to do is to go to our CLI, set up a different stack, and execute the same code. Maintain Extensibility and Modularity Use the built-in ones or define your own custom flavors! The good thing is, that ZenML already comes equipped with a wide variety of implementations for these components. For example, you can use Airflow or Kubeflow to orchestrate the pipelines, Seldon or MLFlow to deploy your models, and Weights and biases to track your experiments. And this list keeps growing every day. Furthermore, you can always use the simple base abstractions to create your own integrations. For example, you can write an Argo Workflows orchestrator by overriding a simple interface and registering it via the CLI. That's it for the short introduction. To see ZenML in action, go ahead, open your terminal, and type: ​ https://preview.redd.it/11b16l9r7n191.png?width=261&format=png&auto=webp&s=56073ddd06504611e17809ac47cdc11c222806b5 GitHub: https://github.com/zenml-io/zenml ZenML Website: https://zenml.io/home Docs: https://docs.zenml.io/ So, what do you think? Exactly what we need in MLOps or just another tool for you? Looking forward to your feedback in the comments below! submitted by /u/htahir1 [link] [comments]

  • [P] Looking for advice how to apply clustering to learned embeddings of user-item interactions
    by /u/the_Wallie (Machine Learning) on May 25, 2022 at 3:31 pm

    hi, I'm working on a consumer segmentation job, where the goal is to understand if there are subgroups of consumers who behave in a similar way to each other, but different from the rest of the population. My dataset contains a user interacting with an item for a period of time, with a reasonable assumption that more time spent means a more favorable view of the item (so we can take the time spent as a proxy for the user's taste). So far, I've created an ML model to learn embeddings of size 64 to represent my approximately 950k users and their interactions with the ~10k items. My original plan was to apply k-means clustering to those 64-dimensional user embeddings. However, this approach isn't yielding the degree of separation I require (e.g. the top most popular items to interact with are all the same ones for each cluster). Trying different values for k, I also get a basically entirely flat elbow graph. How should I proceed from here? I've thought of 2 options: - retraining my embeddings with a smaller size and retrying with k-means - researching an alternative clustering algorithm is there anything I haven't considered yet, but should? If no, which of these 2 approaches would you explore first, and if you prefer the latter, which algorithm(s) would you test out first? Thanks for your help! submitted by /u/the_Wallie [link] [comments]

  • [D] Different input image size when using Visual Transformers
    by /u/alkibijad (Machine Learning) on May 25, 2022 at 3:14 pm

    I have an image classification problem, and have been using ResNet. The dense layers at the end are replaced with 1x1 convolutions, making the model fully convolutional. Classification is done on 128 x 128 patches, so if the input image is 128 x 128, I'll get output size 1x1. If image is 512 x 512, the output will be 4x4. Each output element will hold the prediction to which class the patch at that position belongs to. Now I'd like to try using transformer instead of ResNet. Can a similar thing be done with Vision Transformers? Are there any examples of that being done? submitted by /u/alkibijad [link] [comments]

I'm looking into building a SaaS feature that require speech to text. As an MVP, we've been using Google's speech to text API which is great - with a few problems - it's cost, and accuracy. While its accuracy is quite high, its cost, if I'm calculating correctly, relatively to our pricing, would be quite high. There are also benefits in terms of building accurate models for the specific industry we'd be using it.

  • [P] Introducing BlindAI, an Open-source, fast and privacy-friendly AI deployment solution. Benefit from state-of-the-art AI without ever revealing your data!
    by /u/Separate-Still3770 (Machine Learning) on May 24, 2022 at 4:07 pm

    Hello everyone, We are pleased to introduce BlindAI to the AI community. BlindAI is an AI deployment solution, leveraging secure enclaves, to make remotely hosted AI models privacy friendly. Please have a look at our GitHub (https://github.com/mithril-security/blindai) to find out more! Motivation Today, most AI tools offer no privacy by design mechanisms, so when data is sent to be analysed by third parties, the data is exposed to malicious usage or potential leakage. We illustrate it below with the use of AI for voice assistants. Audio recordings are often sent to the Cloud to be analysed, leaving conversations exposed to leaks and uncontrolled usage without users’ knowledge or consent. ​ Before and after BlindAI By using BlindAI, data remains always protected as it is only decrypted inside a Trusted Execution Environment, called an enclave, whose contents are protected by hardware. While data is in clear inside the enclave, it is inaccessible to the outside thanks to isolation and memory encryption. This way, data can be processed, enriched, and analysed by AI, without exposing it to external parties. What you can do We have been able to run several state of the art models with privacy guarantees, enabling us to tackle complex scenarios, from privacy-friendly voice assistant with Wav2vec2, to confidential chest X-Ray analysis with ResNet, through document analysis with BERT. All of these models have been tested and can run with end-to-end protection under a second on an Intel(R) Xeon(R) Platinum 8370C. Model name Example use case Inference time (ms) DistilBERT Sentiment analysis 28.435 Wav2vec2 Speech to text 617.04 Facenet Facial recognition 47.135 A more detailed list of models we can deploy with privacy, with their run time, can be found here.

  • [P] What we learned by making T5-large 2X faster than Pytorch (and any autoregressive transformer)
    by /u/pommedeterresautee (Machine Learning) on May 24, 2022 at 6:49 am

    TL;DR We made autoregressive transformer based models like T5-large 2X faster than 🤗 Hugging Face Pytorch with 3 simple tricks: storing 2 computation graphs in a single Onnx file 👯: this let us have both cache and no cache support without having any duplicated weights. When cache is used, attention switch from quadratic to linear complexity (less GPU computation) and Onnx Runtime brings us kernel fusion (less memory bound ops); zero copy 💥 to retrieve output from Onnx Runtime: we leverage Cupy API to access Onnx Runtime internal CUDA arrays and expose them through Dlpack to Pytorch. It may sound a bit complex, but it let us avoid output tensors copy which limit our memory footprint and make us much faster (check notebook for other benefits of this approach); a generic tool to convert any model (whatever the architecture) to FP16: it injects random inputs in the model to detect nodes that need to be kept in FP32 because "mixed precision" is more complicated on large generative models (usual patterns don't work at large scale). notebook: https://github.com/ELS-RD/transformer-deploy/blob/main/demo/generative-model/t5.ipynb (Onnx Runtime only) project: https://github.com/ELS-RD/transformer-deploy/ For TensorRT we have our own implementation of our approach described above which helps to provide similar latency to Onnx Runtime. It's in a dedicated Python script in the same folder as the notebook. We had to work around a documented limitation. Because of that the code is slightly more complex and we wanted to keep this notebook easy to read. https://github.com/ELS-RD/transformer-deploy/blob/main/demo/generative-model/t5_tensorrt.py text generation in 2 different setups: no cache == no long seq len The challenge We plan to use large autoregressive models like T5 mainly for few shots learning but they tend to be slow. We needed something faster (including long sequences, large models, etc.), easy to deploy (no exotic/custom framework/hardware/kernel) and generic (works on most generative transformer models, NLP related or not, compatible with Onnx Runtime and TensorRT that we are using for other stuff). In most situations, performing inference with Onnx Runtime or TensorRT usually brought large improvement over Pytorch/Hugging Face implementation. In the very specific case of autoregressive languages, things are a bit more complicated. As you know (if not, check the notebook above for a longer explanation), you can accelerate an autoregressive model by caching Key/Value representations. By using a cache, for each generated token, you are switching from a quadratic complexity to a linear one in the self/cross attention modules. Only the first generated token is done without cache. Hugging Face is using this mechanism. When you export your model to Onnx using tracing, any control flow instruction is lost (including the If instruction to enable or not a cache). All the T5 inference solutions we found seem to suffer from it (a list of existing solutions and their issues is provided in the notebook). Performance analysis and next steps With our simple approach, we have made the inference latency mostly linear to the sequence length.Profiling the GPU with Nvidia Nsight shows that GPU computation capacities are mostly unused. It likely means that we are memory bounded, it would make sense as for each step, we just perform computations for a single token. Left side, no cache, GPU is very busy, right side, GPU is waiting memory bound operations (timings are wrong because of the profiler overhead). Going deeper in the analysis, Onnx Runtime profiler confirms that we are memory bounded and spend lots of time on casting to FP16/FP32. A strategy to increase performances would be to reduce the number of casting nodes (by a second pass on the graph to remove unnecessary casting nodes). Casting nodes should be easy to reduce. Second point, MatMul (the only operation where GPU computation capacities are fully used) represent a little part of the latency because now attention is computed for only one token (excepted the first one). It means that after these transformations of the computation graph, kernel fusions to reduce the number of memory bounded operations should pay off in a much bigger way than it did in the past. Hopefully such kernel fusions will land in both TensorRT and Onnx Runtime soon. Nvidia Triton server deployment will be released when Onnx Runtime 1.12 will be supported (ORT 1.12 should be released in June, and Triton... soon after ?). ​ If you are interested in these things, you can follow me on twitter: https://twitter.com/pommedeterre33 submitted by /u/pommedeterresautee [link] [comments]

AWS Developer Certification Exam Prep App Content:

The App covers the following topics:

  • Use AWS Cheatsheets – I also found the cheatsheets provided by Tutorials Dojo very helpful. In my opinion, it is better than Jayendrapatil Patil’s blog since it contains more updated information that complements your review notes.
    #AWS Cheat Sheet
  • Do not rush into completing the videos. Take your time and hone the basics. Focus and spend a lot of time for the back bone of AWS infrastructure – Compute/EC2 section, Storage (S3/EBS/EFS), Networking (Route 53/Load Balancers), RDS, VPC, Route 3. These sections are vast, with lot of concepts to go over and have loads to learn. Trust me you will need to thoroughly understand each one of them to ensure you pass the certification comfortably.

  • Make sure you go through resources section and also AWS documentation for each components. Go over FAQs. If you have a question, please post it in the community. Trust me, each answer here helps you understand more about AWS.
    #AWS Faqs
  • Like any other product/service, each AWS offering has a different flavor. I will take an example of EC2 (Spot/Reserved/Dedicated/On Demand etc.). Make sure you understand what they are, what are the pros/cons of each of these flavors. Applies for all other offerings too.
