Often while working with Artificial Neural Networks or other variations like Convolution Neural Networks or Recurrent Neural Networks, we want to visualize and create a diagrammatic representation of our compiled model. There are a few packages readily available in python that can create a visual representation of our Neural Network Models. The first three packages can be used even before a model is trained (the model needs to be defined and compiled only); however, Tensor Boards requires the user to train the model on accurate data before the architecture can be visualized. We don't need to install the "Tensor Board" and "Keras Model Plot" separately. This will come with the initial installation of Tensorflow & Keras.

MLOps is composed by Continuous Integration (CI -- code, unit testing, remerge code), Continuous Delivery (CD -- build, test, release) and Continuous Training (CT -- train, monitor, measure, retrain, serve). Consider the following situation: you develop a solution where you will offer product search for users. There are new users every minute and new products every day. In this situation we will have an index of embeddings containing all the products, and users query will be submitted as numerical vectors to this index, to check for the best results. This index is deployed in a container inside Vertex AI endpoints.

A computational graph in a deep neural network (DNN) denotes a specific data flow diagram (DFD) composed of many tensors and operators. Existing toolkits for visualizing computational graphs are not applicable when the structure is highly complicated and large-scale (e.g., BERT [1]). To address this problem, we propose leveraging a suite of visual simplification techniques, including a cycle-removing method, a module-based edge-pruning algorithm, and an isomorphic subgraph stacking strategy. We design and implement an interactive visualization system that is suitable for computational graphs with up to 10 thousand elements. Experimental results and usage scenarios demonstrate that our tool reduces 60% elements on average and hence enhances the performance for recognizing and diagnosing DNN models. Our contributions are integrated into an open-source DNN visualization toolkit, namely, MindInsight [2].

MLPerf training times represent the state of the art in machine learning performance, in which AI industry leaders publish their best training times for a set of common machine learning models. But optimizing for training speed means these models are often complex, and difficult to move to practical applications. Last year, we published SageMakerCV, a collection of computer vision models based on MLPerf, but with added flexibility and optimization for use on Amazon SageMaker. The recently published MLPerf 2.0 adds a series of new optimizations. In this blog, discuss those optimizations, and how we can use PyTorch Lightning and the SageMaker Debugger to further improve training performance and flexibility.

Model hyperparameters, performance measurements, run logs, model artifacts, data artifacts, etc., are all included in this. There are numerous approaches to implementing experiment logging. Spreadsheets are one option (no one uses them anymore!), or you can use GitHub to keep track of tests. Tracking machine learning experiments has always been a crucial step in ML development, but it used to be a labor-intensive, slow, and error-prone procedure. The market for contemporary experiment management and tracking solutions for machine learning has developed and increased over the past few years.

NEVIS'22 is a benchmark for measuring the performance of algorithms in the field of continual learning. Please see the accompanying paper for more details. NEVIS'22 is composed of 106 tasks chronologically sorted and extracted from publications randomly sampled from online proceedings of major computer vision conferences over the past three decades. Each task is a supervised classification task, which is the most well understood setting in machine learning. The challenge is how to automatically transfer knowledge across related tasks in order to achieve a higher performance or be more efficient on the next task.

T5X is a modular, composable, research-friendly framework for high-performance, configurable, self-service training, evaluation, and inference of sequence models (starting with language) at many scales. It is essentially a new and improved implementation of the T5 codebase (based on Mesh TensorFlow) in JAX and Flax. Below is a quick start guide for training models with TPUs on Google Cloud. For additional tutorials and background, see the complete documentation. Vertex AI is a platform for training that creates TPU instances and runs code on the TPUs.

Experiment tracking has been one of the most popular topics in the context of machine learning projects. It is difficult to imagine a new project being developed without tracking each experiment's run history, parameters, and metrics. While some projects may use more "primitive" solutions like storing all the experiment metadata in spreadsheets, it is definitely not a good practice. It will become really tedious as soon as the team grows and schedules more and more experiments. Many mature and actively developed tools can help your team track machine learning experiments. In this article, I will introduce and describe some of these tools, including TensorBoard, MLFlow, and Neptune.ai,

A word embedding is any method which converts words into numbers, and it is the primary task of any Machine Learning (ML) workflow involving text data. Independently from the problem being faced (classification, clustering, …), leveraging an effective numeric representation of the input text is paramount to the success of the ML model. But what is an effective numeric representation of text? Basically, we want to embed a word in a number or a vector able to convey information about the meaning of a word. One way to intuitively appreciate this concept is provided by word analogies¹, i.e. relationships of the form: "word₁ is to word₂ as word₃ is to word₄".
