</b><br>For each drilling site, there are thousands of different equipment operating simultaneously 24/7. For the oil & gas industry, the downtime can cost millions of dollars daily. As current standard practice, the majority of the equipment are on scheduled maintenance with standby units to reduce the downtime. Scheduled maintenance treats each equipment similarly with simple metrics, such as calendar time or operating time. Using machine learning models to predict equipment failure time accurately can help the business schedule the predictive maintenance accordingly to reduce the downtime and maintenance cost. We have huge sets of time series data and maintenance records in the system, but they are inconsistent with low quality. One particular challenge we have is that the data is not continuous and we need to go through the whole data set to find where the data are continuous over some specified window. Transforming the data for different time windows also presents a challenge: how can we quickly pick the optimized window size among the various choices available and perform transformation in parallel? Data transformations such as the Fourier transforms or wavelet transforms are time consuming and we have to parallelize the operation. We adopted Spark dataframes on Databricks for our computation. Here are the two major steps we took to carry out the efficient distributed computing for our data transformations: 1. Identify which segments have continuous data by scanning through a sub-sampled data set. 2. Pick different windows and transform data within the window. 3. Transform each window column into one cell as a list. 4. Preserve the order of the data in each cell by collecting the timestamp and the corresponding parameter as a list of dictionaries, and then reorder the list based on the timestamp element in the dictionaries.

| + | <b>Optimised Predictive Maintenance: a Dataiku x HPE Webinar | ||
| + | </b><br>The predictive maintenance market will reach $11 Billion by 2022, driven by Internet of Things (IoT) technology and new services. Predictive maintenance translates into profound business benefits: reduced costs (resources and parts), less downtime, optimized maintenance scheduling, accurate defect diagnosis, and much more. In this webinar, learn how to build an end-to-end predictive and prescriptive maintenance solution open framework based on machine learning and deep learning techniques with Dataiku and HPE. | ||
| + | The webinar will be broken down into three parts: - Introduction to predictive and prescriptive maintenance, answering questions like "What is predictive maintenance?" and "How can you move from a model where you know what can happen to a prescriptive model where you will know exactly what will happen along with the associated costs?" | ||
| + | - Step-by-step demo of a use case going from data acquisition to action activation through optimized prediction algorithms. We will explain how to implement an effective predictive solution using different data sources (PMU, ERP, Prot, network repository, etc.). | ||

| + | <b>Tech Talk | Predictive Maintenance (PdM) on IoT Data for Early Fault Detection w/ Delta Lake | ||
| + | </b><br>Join us for an online tech talk on Delta Lake. Tech talks include a technical presentation with slides and a demo, with time for Q&A at the end. Predictive Maintenance (PdM) is different from other routine or time-based maintenance approaches as it combines various sensor readings and sophisticated analytics on thousands of logged events in near real time and promises several fold improvements in cost savings because tasks are performed only when warranted. The top industries leading the IoT revolution include manufacturing, transportation, utilities, healthcare, consumer electronics & cars. The global market size for this is expected to grow at a CAGR of 28%. PdM plays a key role in Industry 4.0 to help corporations not only reduce unplanned downtimes, but also improve productivity and safety. The collaborative Data and Analytics platform from Databricks is a great technology fit to facilitate these use cases by providing a single unified platform to ingest the sensor data, perform the necessary transformations and exploration, run ML and generate valuable insights. | ||

| + | <b>HPE: Ultra-Reliable Low-Latency Solutions for Industry 4.0 Predictive Maintenance Use Cases | ||
| + | </b><br>The Fourth Generation of the Industrial (Iv4) revolution parallels the global launch of the Fifth Generation (5G) of wireless networks. Comprised of Cyber Physical Systems (CSP), Industrial Internet of Things (IIoT), Cloud Solutions & Decentralized Services, Extreme-Scale Big Data and Real-Time Streams Processing Frameworks, Artificial Intelligence is imbedded in Iv4. In order for these novel Iv4 solutions to leverage 5G's new Ultra-Reliable Low-Latency Communication (URLLC) service paradigm, comparable real-time, low-latency tools like Aerospike Enterprise Server are placed on the front lines to support these Iv4’s intelligent products, processes, and machine use cases. This intelligent automation and data exchange is showcased in the predictive maintenance use cases for wind turbines and railways. | ||

| + | <b>Rethinking Predictive Maintenance | Zaid Tashman | AI Conference London | ||
| + | </b><br>Traditional approaches to predictive maintenance fall short in today’s data-intensive and IoT-enabled assets. In this talk we introduce a novel machine learning based approach to predicting the time of occurrence of rare events using mixed membership hidden markov models. We show how we use these models to learn complex stochastic degradation patterns from data by introducing a terminal state that represents the failure state of the asset, whereas other states represent “health” states of the asset as it progresses towards failure. The probability distribution of these non-terminal states and the transition probabilities between states are learned from data. | ||
