DIGITAL TRANSFORMATION – CHALLENGES IN MACHINE LEARNING
Machine learning is not just a hot technology trend. It is having a large impact in the digital transformation of businesses.
Machine learning enables digital transformation and increases RoI by greatly improving operational efficiencies and customer experiences in your business. It can analyze much more data than is physically possible, and provide more, faster and better conclusions, which can help digitize and streamline business processes for rapid decision making and execution without human intervention.
Some applications of machine learning include:
- Failure prevention for a wide variety of devices, and systems by predicting failure possibilities early
- Anomaly detection in streaming data from devices, or other data sources like document digitization systems for quality control
- Quick and accurate analysis based on images, and historical data
- Fraud detection in financial transactions, especially credit cards, to quickly detect frauds and take actions, or even proactively prevent them
- Sentiment analysis on social media posts, news feeds, and other forms of text feeds
If you have implemented big data for your products and services as part of your digital transformation initiative, then you could consider machine learning to accelerate your digital transformation and RoI. Big data can potentially be used to train, test and retrain machine learning models.
While machine learning is promising, there are complexities and challenges that you need to consider:
Not only is machine learning data hungry, it also requires organized and prepared data. It is likely that such good data is not available in your business, and needs to be sourced from industry data, which may be expensive or not easily accessible.
Machine learning is compute intensive and requires significant computing infrastructure for experimentation and testing. This may not be available internally and require significant budgets.
Machine learning is new technology. Skilled resources are in short supply and can be quite expensive to hire.
Machine learning technology is still young and evolving. You need to understand the limits of contemporary machine learning technology, be realistic and allow time for achieving satisfactory results. As the machine learning model learns and executes, it increasingly becomes a black box – it may not be possible for us to understand the rationale behind certain actions.
ou need to carefully select the problems you’re looking to automate. Simple processes that are executed frequently and manually with limited outcomes are easier to automate than complicated ones which require careful thought. Also, not all processes that can be automated require machine learning.
Not withstanding these challenges, machine learning is become more accessible with increased computing power of GPUs, CPUs and FPGA processors, enhanced and optimized algorithms and tools to leverage the increased compute power, and the easy, cost-effective availability of cloud-based high performance computing infrastructure. More problems are being solved, and outsourced services providers are bridging the availability of skilled resources in a cost-effective manner.
DIGITAL TRANSFORMATION – TRENDS FOR MACHINE LEARNING
Digital transformation is driving changes in machine learning. Some of the trends in machine learning include:
A wide range of machine leaning tools from leading vendors and open source are now available that let your data scientists focus more on their competences. Tools like MLflow™, Amazon SageMaker® and Azure® Machine Learning Service track different experiment iterations, libraries like Keras, TensorFlow™, Microsoft® Cognitive Toolkit (CNTK) on Azure and Chainer build state of the art models, developer environments like Amazon SageMaker and Azure Machine Learning Studio/WorkBench manage the computing infrastructure, and automated deployment tools like Amazon SageMaker and Azure Machine Learning Ops help in deploying machine learning models.
Automated Machine Learning
The availability of new, advanced automated machine learning tools like Google’s Cloud AutoML is expected to fundamentally change machine learning and increase adoption across industries. They could empower your business analysts to evolve machine learning models that can address complex scenarios, without getting lost in processes, workflows and training models.
Neural Networks Interoperability
Once a model is trained and evaluated in a specific tool framework, it is difficult to port the trained model to another framework. To address this challenge, AWS®, Facebook™ and Microsoft® have collaborated to build Open Neural Network Exchange (ONNX) for neural networks Interoperability, which makes it possible to reuse trained neural network models across multiple frameworks.
New, high performance chips and specialized hardware optimized for specific use cases and scenarios will accelerate machine learning. They will speed up the execution of training machine learning models and complex mathematical computations required for computer vision, natural language processing, speech recognition, etc.
Edge Machine Learning
With the increase in connected devices, more and more machine learning models trained in the cloud will be optimized and deployed at the edge. Edge machine learning enables inference at the edge, which takes less computing power and can be done in real-time when new data is available, with very low latency and rapid response to local events.
