optimization for big data

Big Data collected to optimize supply chain management often holds key insights about consumer needs and wants. That’s why you need to carefully think through the execution process. This methodology has gained popularity in the transport and logistics industry. The advantage of taking s > 1 is that it can be parallelized so that different computers can handle different samples, making it more efficient. Dynamic pricing can also be used to maximize revenue during times of increased market demand and/or supply shortages. Performance tuning and optimization for specific big data platforms or applications (e.g., No-SQL databases, graph processing systems, stream systems, SQL-on-Hadoop databases) Performance tuning and optimization for specific data sets (e.g., scientific data, spatial data, temporal data, text data, images, videos, mixed datasets) Evolutionary algorithms' superior exploration skills should make them promising candidates for handling optimization problems involving big data. Obiettivi. Some concrete examples where this formulation is used to find optimal weights are for a linear regression. Optimization for Speculative Execution in Big Data Processing Clusters ABSTRACT: A big parallel processing job can be delayed substantially as long as one of its many tasks is being assigned to an unreliable or congested machine. Big Data for Process Optimization – Technology Requirements. Preprocessing the data is a very important, time-consuming and complicated task where the noise is filtered out from huge volumes of unstructured and structured data continuously and the data is compressed by understanding and capturing the context into which data has been generated. For example, a smart device can be built to send messages to the manufacturer when they are broken, which can generate production on a replacement part or full device, before its owner calls customer service. For example, a corporate fleet might count as KPIs on-time deliveries, cost per delivery measured in fuel, wear and tear, and other measures, delivery times, positive customer feedback, lack of negative customer feedback, and other similar indicators. Stochastic methods use a random subset S of size s of the n observations, or a random subset T of size t of the d variable (s < < n, t < < d), instead of calculating the descent direction with all the available data at once. Firms can use consumer data, from both internal and external sources, to develop pricing models that maximize profit margins, and use predictive analytics tools to forecast demand for a particular product at different price points. Cloud computing itself has driven Big Data’s growth significantly, as its inherent digitization of a firm’s operational data demands new methods to leverage it. Firms can then test these price points with soft launches, and incorporate consumer behavior and feedback – both quantitative and qualitative – into their pricing strategies. Firms that demonstrate such value to consumers can increase repeat purchase behavior, deepen consumer brand loyalty, and derive more value (purchases and referrals) from the customer over his or her lifetime. Several optimization algorithms for big data including convergent parallel algorithms, limited memory bundle algorithm, diagonal bundle method, convergent parallel algorithms, network analytics, and many more have been explored in this book. is a random estimate of the Gradient, rather than using the full dataset to compute, As it can be seen, in the long run, updating, with various samples will have the same effect as updating.

As time passes, those firms who have integrated Big Data into their supply chains, and both scale and refine that infrastructure will likely have a decisive competitive advantage over those that do not. with n observations and d variables, a target variable.
