To predict the behavior of a physical system governed by a complex mathematical model depends on un- derlying model parameters. For example, predicting the contaminant transport or oil production strongly influenced by subsurface properties, such as permeability, porosity and other spatial fields. These spatial fields are highly heterogeneous and vary over a rich hierarchy of scales, which makes the forward models

As the model is represented by continuous functions with specific outputs for a particular input, it is continuous and deterministic. The ability to extend the domain of the model to predict future populations shows that this type of model is an explanatory model.

Complexity Learning Theory describes how situations unfold unpredictably from the components that are in play around them.

Researchers in the field of neuroscience have long disputed the type of neural modelling that allows for the processing of visual stimuli in the brain. I believe that a hierarchical framework exists in which both distributed and localised modelling can occur at different stages. Distributed modelling occurs at lower hierarchal levels and localised modelling, characterised by grandmother cells, occurs at higher levels. Neurons in higher levels pool information passed on from lower levels to so that the representation of concepts becomes more complex and specialised. It is through this formation of grandmother cells that a visual stimulus can be represented in the brain in an invariant manner.

More accuracy can be achieved by refining our data and knowing the significance of different attributes in the data, or the role of training or transfer functions. The role of neural networks and its working is still a mystery and is gradually evolution

This is useful like why this thing is going. Then what next. This predictive ability us dependent on the goodness of fit of the statistical model.

Multilayer Perceptron (MLP) is an artificial neural network that learns nonlinear function mappings. An MLP can be viewed as a logistic regression classifier where the input is first transformed using a learned non-linear transformation. This transformation projects the input data into space where it becomes linearly separable. This intermediate layer is referred to as a hidden layer. A single hidden layer is sufficient to make MLPs a universal approximator.

This, in turn, indicates that the model has the most accurate relationship with the data given and can be used to extrapolate valid results for all values as the pattern repeats itself after a set period. For a scatterplot of data points, please refer to Task 2.

Analyzing seemingly random data or patterns in chaos will allow you to predict the future

First, we have encountered one major problem that is how to interpret a neural network given its black box characteristics. We really wanted to try ourselves, giving interpretation of our results so that we dug into the existing literature and found out a very interesting research paper written by Garson in 1991. In « Illuminating the black box: a randomization approach for understanding variable contributions in artificial neural networks », Olden and al. describes Garson’s algorithm very concisely so that we could create a user-defined function on Python that replicates the method. The interpretation of the method is provided below. The outputs of the different algorithms in the context of our study:

Tekin et. al. (2013) provided a context information based method for improving the big data classification so that the conceptual information will be derived. Author applied work on distributed large and heterogenous datset. The data is collected from multiple streams so that the function driven classifier is applied to cover the complexities of individual stream. The local perspective method method is deifned under learning method to reduce the cost and to include the benefits associated to the learner and provide the contextual results. The data characterization is also provided by the work with improved mining model[5].

Soft computing techniques uses simple rules to model the system dynamics without knowing the mathematical model of the complex nonlinear system. Fuzzy controller is an intelligent controller based on the model of fuzzy logic that uses simple if-then rules and adds human intelligence so that the fuzzy controller does not require accurate mathematical modelling of the system. Neural networks,

Artificial neural networks (ANNs) are computational algorithms loosely based on the human biological nervous system which work to model statistical data. An ANN “consists of processing elements known as neurons that are interconnected to each other and work in unison to answer a particular problem [, and] can be used in places where detecting trends and extracting patterns are too complex to be detected by either humans or other computer techniques.” Although recent in their explosion in popularity, the underlying logic behind ANNs have existed for “nearly a half-century”, however due to the pervasive and ubiquitous adoption of powerful computational tools in our contemporary society, ANNs have had a sort of renaissance, much to the avail of scientists, engineers, and consumers.

Convolutional neural systems (CNNs) are suitable for unraveling visual record that depend on hand writing recognition task and characterization [1, 3]. They have an adaptable design which do not need to have complex strategies, for instance, momentum, weight rot, structure dependent learning rates or even finely tuning the engineering[1]. CNNs have additionally accomplished the cutting edge comes about for character acknowledgment on the MNIST informational collection of manually written English digit pictures [2].
