WHAT IS NEURAL NETWORK?
The method calculation is based on the interaction of plurality of processing elements inspired by biological nervous system called neurons.
It is a powerful technique to solve real world problem.
A neural network is composed of a number of nodes, or units[1], connected by links. Each linkhas a numeric weight[2]associated with it. .
Weights are the primary means of long-term storage in neural networks, and learning usually takes place by updating the weights.
Artificial neurons are the constitutive units in an artificial neural network.
WHY USE NEURAL NETWORKS?
It has ability to Learn from experience.
It can deal with incomplete information.
It can produce result on the basis of input, has not been taught to deal with.
It is used to extract useful pattern from given data i.e. pattern Recognition etc.
Biological Neurons
Four parts of a typical nerve cell :• DENDRITES: Accepts the inputs• SOMA : Process the inputs• AXON : Turns the processed inputs into outputs.• SYNAPSES : The electrochemical contactbetween the neurons.
ARTIFICIAL NEURONS MODEL
Inputs to the network arerepresented by the x1mathematical symbol, xn
Each of these inputs are multiplied by a connection weight , wn
sum = w1 x1 + ……+ wnxn
These products are simplysummed, fed through the transfer function, f( ) to generate a result and then output.
NEURON MODEL
Neuron Consist of:
Inputs (Synapses): inputsignal.Weights (Dendrites):determines the importance ofincoming value.Output (Axon): output toother neuron or of NN .
An Artificial Neural Network (ANN) is a computational model inspired by the structure and functioning of the human brain's neural networks. It consists of interconnected nodes, often referred to as neurons or units, organized in layers. These layers typically include an input layer, one or more hidden layers, and an output layer.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neural Networks
• A NN is a machine learning approach inspired by the
way in which the brain performs a particular learning
task:
– Knowledge about the learning task is given in the form of
examples.
– Inter neuron connection strengths (weights) are used to
store the acquired information (the training examples).
– During the learning process the weights are modified in
order to model the particular learning task correctly on the
training examples.
4. 4
• Supervised Learning
– Recognizing hand-written digits, pattern recognition,
regression.
– Labeled examples
(input , desired output)
– Neural Network models: perceptron, feed-forward, radial
basis function, support vector machine.
• Unsupervised Learning
– Find similar groups of documents in the web, content
addressable memory, clustering.
– Unlabeled examples
(different realizations of the input alone)
– Neural Network models: self organizing maps, Hopfield
networks.

Real Neural Learning
• Synapses change size and strength
with experience.
• Hebbian learning: When two connected
neurons are firing at the same time, the
strength of the synapse between them
increases.
• “Neurons that fire together, wire
together.”
12. Neural Networks NN 1 12
The Artificial Neuron
• The neuron is the basic information processing unit of
a NN. It consists of:
1 A set of synapses or connecting links, each link
characterized by a weight:
W1, W2, …, Wm
2 An adder function (linear combiner) which
computes the weighted sum of
the inputs:
3 Activation function (squashing function) for
limiting the amplitude of the
output of the neuron.

Dimensions of a Neural
Network
• Various types of neurons
• Various network architectures
• Various learning algorithms
• Various applications
17. Backpropagation Training
Algorithm
17
•Create the 3-layer network with H hidden units with full
connectivity between layers. Set weights to small random real
values.
•Until all training examples produce the correct value (within ε),
or mean squared error ceases to decrease, or other termination
criteria:
Begin epoch
For each training example, d, do:
Calculate network output for d’s input values
Compute error between current output and correct output for d
Update weights by backpropagating error and using learning rule
End epoch
18. 18
Comments on Training Algorithm
• Not guaranteed to converge to zero training error,
may converge to local optima or oscillate indefinitely.
• However, in practice, does converge to low error for
many large networks on real data.
• Many epochs (thousands) may be required, hours or
days of training for large networks.
• To avoid local-minima problems, run several trials
starting with different random weights (random
restarts).
– Take results of trial with lowest training set error.
– Build a committee of results from multiple trials (possibly
weighting votes by training set accuracy).
19. 19
Over-Training Prevention
• Running too many epochs can result in over-fitting.
• Keep a hold-out validation set and test accuracy on it after
every epoch. Stop training when additional epochs actually
increase validation error.
• To avoid losing training data for validation:
– Use internal 10-fold CV on the training set to compute the average
number of epochs that maximizes generalization accuracy.
– Train final network on complete training set for this many epochs.

Determining the Best
Number of Hidden Units
• Too few hidden units prevents the network from
adequately fitting the data.
• Too many hidden units can result in over-fitting.
• Use internal cross-validation to empirically determine
an optimal number of hidden units.
