Most retail/e-retail brands, plan their short-term inventory (2-4 weeks ahead) based on consumer purchase pattern. Also, certain sales and marketing strategies like Offer Personalization and personalized item recommendations are made leveraging results of consumer purchase predictions for the near future. Given that every demand planner works on a narrow segment of item portfolio, there is a high variability in choices that different planners recommend. Additionally, the demand planners might not get enough opportunities to discuss their views and insights over their recommendations. Hence, subtle effects like cannibalization [21], and item affinity remain unaccounted for. Such inefficiencies lead to a gap between consumer needs and item availability, resulting in the loss of business opportunities in terms of consumer churn, and out-of-stock and excess inventory

#ML-engineering #ML_in_Action #learning #machine #software-engineering
The aim of ML engineering is not to iterate through the lists of skills just mentioned and require that a data scientist (DS) master each of them. Instead, ML engineering collects certain aspects of those skills, carefully crafted to be relevant to data scientists, all with the goal of increasing the chances of getting an ML project into production and making sure that it’s not a solution that needs constant maintenance and intervention to keep running

#ML-engineering #ML_in_Action #learning #machine #software-engineering
Throughout this first part of the book, we’ll discuss how to identify the reasons so many projects fail, are abandoned, or take far longer than they should to reach production. We’ll also discuss the solutions to each of these common failures and cover the processes that can significantly lower the chances of these factors derailing your projects. Generally, these failures happen because the DS team is either inexperienced with solving a problem of the scale required (a technological or process-driven failure) or hasn’t fully understood the desired outcome from the business (a communication- driven failure). I’ve never seen this happen because of malicious intent. Rather, most ML projects are incredibly challenging, complex, and composed of algorithmic software tooling that is hard to explain to a layperson—hence the breakdowns in communication with business units that most projects endure

#ML-engineering #ML_in_Action #learning #machine #software-engineering
Project scoping for ML is incredibly challenging. Even for the most seasoned ML veterans, conjecturing how long a project will take, which approach is going to be most successful, and the amount of resources required is a futile and frustrating exercise. The risk associated with making erroneous claims is fairly high, but structuring proper scoping and solution research can help minimize the chances of being wildly off on estimation.

Most companies have a mix of the types of people in this hyperbolic scenario. Some are academics whose sole goal is to further the advancement of knowledge and research into algorithms, paving the way for future discoveries from within the industry. Others are “applications of ML” engineers who just want to use ML as a tool to solve a business problem. It’s important to embrace and balance both aspects of these philosophies toward ML work, strike a compromise during the research and scoping phase of a project, and know that the middle ground here is the best path to trod upon to ensure that a project actually makes it to production.

We will systematically go through the stack of systems that make a modern, effective infrastructure for data science. The principles covered in this book are not specific to any particular implementation, but we will use an open source framework, Metaflow, to show how the ideas can be put into practice. Alternatively, you can customize your own solution by using other off-the-shelf libraries. This book will help you to choose the right set of tools for the job

Deep Learning Has Reinvented Quality Control in Manufacturing—but It Hasn’t Gone Far Enough AI systems that make use of “lifelong learning” techniques are more flexible and faster to train
These so-called continual or lifelong learning systems, and in particular lifelong deep neural networks (L-DNN), were inspired by brain neurophysiology. These deep learning algorithms separate feature training and rule training and are able to add new rule information on the fly. While they still learn features slowly using a large and balanced data set, L-DDNs don't learn rules at this stage. And they don't need images of all known valve defects—the dataset can

By default, the samples within an epoch are shuffled. This is a good practice when working with Multilayer Perceptron neural networks. If you are trying to preserve state across samples, then the order of samples in the training dataset may be important and must be preserved.

As we have shown, it also accurately predicts periods of elevated transaction activity and captures other forms of purchase dynamics that can be leveraged in simulations of future sequences of customer transactions. We highlight our model’s flexibility and performance on two groups of valuable customers: those who keep making more and more transactions with the firm (denoted as ”opportunity” customers) and those who are at risk of defection. We demonstrate that the model also excels at automatically capturing seasonal trends in customer activity, such as the shopping period leading up to the December holidays. In Appendix Section F we provide a further characterization of scenarios where our model performs particularly well and where it does not do so relative to the used benchmark methods.
