Versioning

How to manage model and data versions
Raj Ramesh Managing data versions and model versions is critical in deploying machine learning models. This is because if you want to re-create the models or go back to fix them, you will need both the data that went into training the model and as well as the model hyperparameters itself. In this video I explained that concept. Here's what I can do to help you. I speak on the topics of architecture and AI, help you integrate AI into your organization, educate your team on what AI can or cannot do, and make things simple enough that you can take action from your new knowledge. I work with your organization to understand the nuances and challenges that you face, and together we can understand, frame, analyze, and address challenges in a systematic way so you see improvement in your overall business, is aligned with your strategy, and most importantly, you and your organization can incrementally change to transform and thrive in the future. If any of this sounds like something you might need, please reach out to me at dr.raj.ramesh@topsigma.com, and we'll get back in touch within a day.

Hyperparameter

YouTube search... ...Google search

In machine learning, a hyperparameter is a parameter whose value is set before the learning process begins. By contrast, the values of other parameters are derived via training. Different model training algorithms require different hyperparameters, some simple algorithms (such as ordinary least squares regression) require none. Given these hyperparameters, the training algorithm learns the parameters from the data. Hyperparameter (machine learning) | Wikipedia

Machine learning algorithms train on data to find the best set of weights for each independent variable that affects the predicted value or class. The algorithms themselves have variables, called hyperparameters. They’re called hyperparameters, as opposed to parameters, because they control the operation of the algorithm rather than the weights being determined. The most important hyperparameter is often the learning rate, which determines the step size used when finding the next set of weights to try when optimizing. If the learning rate is too high, the gradient descent may quickly converge on a plateau or suboptimal point. If the learning rate is too low, the gradient descent may stall and never completely converge. Many other common hyperparameters depend on the algorithms used. Most algorithms have stopping parameters, such as the maximum number of epochs, or the maximum time to run, or the minimum improvement from epoch to epoch. Specific algorithms have hyperparameters that control the shape of their search. For example, a Random Forest (or) Random Decision Forest Classifier has hyperparameters for minimum samples per leaf, max depth, minimum samples at a split, minimum weight fraction for a leaf, and about 8 more.

Hyperparameter Tuning

Hyperparameters are the variables that govern the training process. Your model parameters are optimized (you could say "tuned") by the training process: you run data through the operations of the model, compare the resulting prediction with the actual value for each data instance, evaluate the accuracy, and adjust until you find the best combination to handle the problem.

These algorithms automatically adjust (learn) their internal parameters based on data. However, there is a subset of parameters that is not learned and that have to be configured by an expert. Such parameters are often referred to as “hyperparameters” — and they have a big impact ...For example, the tree depth in a decision tree model and the number of layers in an artificial neural network are typical hyperparameters. The performance of a model can drastically depend on the choice of its hyperparameters. Machine learning algorithms and the art of hyperparameter selection - A review of four optimization strategies | Mischa Lisovyi and Rosaria Silipo - TNW

There are four commonly used optimization strategies for hyperparameters:

  1. Bayesian optimization
  2. Grid search
  3. Random search
  4. Hill climbing

Bayesian optimization tends to be the most efficient. You would think that tuning as many hyperparameters as possible would give you the best answer. However, unless you are running on your own personal hardware, that could be very expensive. There are diminishing returns, in any case. With experience, you’ll discover which hyperparameters matter the most for your data and choice of algorithms. Machine learning algorithms explained | Martin Heller - InfoWorld

Hyperparameter Optimization libraries:

Tuning:

  • Optimizer type
  • Learning rate (fixed or not)
  • Epochs
  • Regularization rate (or not)
  • Type of Regularization - L1, L2, ElasticNet
  • Search type for local minima
    • Gradient descent
    • Simulated
    • Annealing
    • Evolutionary
  • Decay rate (or not)
  • Momentum (fixed or not)
  • Nesterov Accelerated Gradient momentum (or not)
  • Batch size
  • Fitness measurement type
  • Stop criteria

Automatic Hyperparameter Tuning

Several production machine-learning platforms now offer automatic hyperparameter tuning. Essentially, you tell the system what hyperparameters you want to vary, and possibly what metric you want to optimize, and the system sweeps those hyperparameters across as many runs as you allow. (Google Cloud hyperparameter tuning extracts the appropriate metric from the TensorFlow model, so you don’t have to specify it.)

AIOps / MLOps

Youtube search... ...Google search

Machine learning capabilities give IT operations teams contextual, actionable insights to make better decisions on the job. More importantly, AIOps is an approach that transforms how systems are automated, detecting important signals from vast amounts of data and relieving the operator from the headaches of managing according to tired, outdated runbooks or policies. In the AIOps future, the environment is continually improving. The administrator can get out of the impossible business of refactoring rules and policies that are immediately outdated in today’s modern IT environment. Now that we have AI and machine learning technologies embedded into IT operations systems, the game changes drastically. AI and machine learning-enhanced automation will bridge the gap between DevOps and IT Ops teams: helping the latter solve issues faster and more accurately to keep pace with business goals and user needs.

Building an MLOps Toolchain The Fundamentals
Artificial intelligence and machine learning are the latest “must-have” technologies in helping organizations realize better business outcomes. However, most organizations don’t have a structured process for rolling out AI-infused applications. Data scientists create AI models in isolation from IT, which then needs to insert those models into applications—and ensure their security—to deliver any business value. In this ebook/webinar, we examine the best way to set up an MLOps process to ensure successful delivery of AI-infused applications.

Shawn Scully: Production and Beyond: Deploying and Managing Machine Learning Models
PyData NYC 2015 Machine learning has become the key component in building intelligence-infused applications. However, as companies increase the number of such deployments, the number of machine learning models that need to be created, maintained, monitored, tracked, and improved grow at a tremendous pace. This growth has lead to a huge (and well-documented) accumulation of technical debt. Developing a machine learning application is an iterative process that involves building multiple models over a dataset. The dataset itself evolves over time as new features and new data points are collected. Furthermore, once deployed, the models require updates over time. Changes in models and datasets become difficult to track over time, and one can quickly lose track of which version of the model used which data and why it was subsequently replaced. In this talk, we outline some of the key challenges in large-scale deployments of many interacting machine learning models. We then describe a methodology for management, monitoring, and optimization of such models in production, which helps mitigate the technical debt. In particular, we demonstrate how to: Track models and versions, and visualize their quality over time Track the provenance of models and datasets, and quantify how changes in data impact the models being served Optimize model ensembles in real time, based on changing data, and provide alerts when such ensembles no longer provide the desired accuracy.
