We can get further latency improvements, reductions in peak memory usage, and access to an integer only hardware accelerators by making sure all model math is quantized. Who “Makes” The Rules? Advanced Machine Learning and Optimization Theories and Algorithms for Heterogeneous Data Analytics Machine learning has been successfully applied to many data analytical tasks, which usually formulate the learning tasks as linear, quadratic or semi-definite mathematical programming problems. you can enforce full integer quantization for all ops and use integer input and output by adding the following lines before you convert. The particular requirements of data analysis problems are driving new research in optimization | much of it being done by machine learning researchers. An Introduction to Supervised Learning. As one of the fundamental prescriptive analysis method, linear programming (LP) is used in all types of organizations, often on a daily basis, to solve a wide variety of problems such as advertising, distribution, investment, production, refinery operations, and transportation analysis. As the name implies its post-training technique, this is after your model is trained. Instead of setting a specific target value for a variable, the goal is to find the optimum value for one or more target variables, under certain constraints. This company used decision optimization and predictive analytics solutions with open-source Python libraries to develop a sophisticated demand forecasting model to predict incoming orders and pickup locations. There are optimization techniques and one of the optimization techniques is Quantization. Kalkitech's data analytics and optimization services helps enable relevant data analysis and obtain actionable insights. /Filter /FlateDecode Descriptive analytics – the use of basic statistics, exploratory data analysis, and data visualization – takes the collected data of a business and summarizes, "slices and dices" that data to gain insights about what has happened. << Now you know exactly quantization, let us, deep dive: Quantization dramatically reduces both the memory requirement and computational cost of using neural networks. We can reduce the size of a floating-point model by quantizing the weights to float16. Deep Learning Techniques and Optimization Strategies in Big Data Analytics is a collection of innovative research on the methods and applications of deep learning strategies in the fields of computer science and information systems. G To overcome post-training quantization technique drawbacks we have quantization aware model training. In this technique Tensorflow created flow, wherein the process of constructing the graph you can insert fake nodes in each layer, to simulate the effect of quantization in the forward and backward passes and to learn ranges in the training process, for each layer separately. Research topics: Stochastic algorithms for optimization, numerical linear algebra, quasi-Newton methods and automatic differentiation (backpropagation).
