   Composed of many “neurons” that co-operate to
    perform the desired function
   Models of the brain and nervous system
   Highly parallel
    ◦ Process information much more like the brain
      than a serial computer
   Learning
   Very simple principles
   Very complex behaviours
   Applications
    ◦ As powerful problem solvers
    ◦ As biological models
 An Artificial Neural Network is a network of many
 very simple processors, each possibly having a local
 memory.


 Theunits are connected by unidirectional
 communication channels, which carry numeric data.


 Theunits operate only on their local data and on the
 inputs they receive via the connections.
 Classification
     Pattern recognition, feature extraction, image matching
 Noise    Reduction
    Recognize patterns in the inputs and produce noiseless
    outputs
 Prediction
    Extrapolation based on historical data
 Ability to learn
   NN’s figure out how to perform their function on their
   own
   Determine their function based only upon sample inputs
 Ability to generalize
   i.e. produce reasonable outputs for inputs it has not been
   taught how to deal with
   A neuron: many-inputs / one-
    output unit
   Dendrites receive activation
    from other neurons
   Axons act as transmission
    lines to send activation to
    other neurons
   Synapses ,the junctions allow
    signal transmission between
    the axons and dendrites
   ANNs incorporate the two fundamental
    components of biological neural nets:


1. Neurones (nodes)
2. Synapses (weights)
 Neurone   vs. Node
 Synapse   vs. weight
   Neuron consists of three basic components.
      1 . Weights
      2 . Thresholds
      3 . Activation function
 Weighting Factors
     The values w1,w2,…wn are weights to determine the
strength of input vector x=[x1,x2,…xn]T
 Thresholds
    The node’s internal threshold is the magnitude offset
 Activation Function
     Performs a mathematical operation on the signal output
     Most common are linear,threshold,S shaped,tangent
hyperbolic function
     Choice of function depend on the problem solved by the
neural network
Neural Networks offer improved performance over
 conventional technologies in areas which includes:

   Machine Vision
   Robust Pattern Detection
   Signal Filtering
   Virtual Reality
   Artificial Life
   and more.
   Advantages
    ◦ Adapt to unknown situations
    ◦ Robustness: fault tolerance due to network
      redundancy
    ◦ Autonomous learning and generalization
   Disadvantages
    ◦ Not exact
    ◦ Large complexity of the network structure
   Learning the Distribution of Object Trajectories for
    Event Recognition
   Radiosity for Virtual Reality Systems
   Speechreading (Lipreading)
   Detection and Tracking of Moving Targets
   Real-time Target Identification for Security
    Applications
   Autonomous Walker & Swimming Eel
   Robocup: Robot
    World Cup Using



   HMM's (hidden
    Markov
    models) for
    Audio-to-Visual
    Conversion


   Artificial Life:
    Galapagos
   The moving target detection and track methods here are "track before detect"
    methods.
   They correlate sensor data versus time and location, based on the nature of
    actual tracks.
   The track statistics are "learned" based on artificial neural network (ANN)
    training with prior real or simulated data.
                                                                 (a) Raw input
                                                                 backgrounds
                                                                 with weak
                                                                 targets included,
                                                                 (b) Detected
                                                                 target sequence
                                                                 at the ANN
                                                                 processing
                                                                 output,
                                                                 post-detection
                                                                 tracking not
                                                                 included
   As part of the research program Neuroinformatik the IPVR
    develops a neural speechreading system as part of a user
    interface for a workstation.
   A neural classifier detects visibility of teeth edges and other
    attributes. At this stage of the approach the edge between the
    closed lips is automatically modeled if applicable, based on a
    neural network's decision.
   The system localises and tracks peoples' faces as they
    move through a scene. It integrates the following
    techniques:
     1. Motion detection
     2. Tracking people based upon motion
     3. Tracking faces using an appearance model
   Faces are tracked robustly by integrating motion and
    model-based tracking.
(A) Tracking in low resolution and poor   (B) Tracking two people
lighting conditions                       simultaneously: lock is maintained
                                          on the faces despite unreliable
                                          motion-based body tracking.

Artificial intelligence NEURAL NETWORKS

  • 1. Uploaded By : REHMAT ULLAH ARTIFICIAL INTELIGENCE,Bcs 6th KUST University,Kohat ,Pakistan 2/8/2012
  • 2. Composed of many “neurons” that co-operate to perform the desired function  Models of the brain and nervous system  Highly parallel ◦ Process information much more like the brain than a serial computer  Learning  Very simple principles  Very complex behaviours  Applications ◦ As powerful problem solvers ◦ As biological models
  • 3.  An Artificial Neural Network is a network of many very simple processors, each possibly having a local memory.  Theunits are connected by unidirectional communication channels, which carry numeric data.  Theunits operate only on their local data and on the inputs they receive via the connections.
  • 4.  Classification Pattern recognition, feature extraction, image matching  Noise Reduction Recognize patterns in the inputs and produce noiseless outputs  Prediction Extrapolation based on historical data
  • 5.  Ability to learn NN’s figure out how to perform their function on their own Determine their function based only upon sample inputs  Ability to generalize i.e. produce reasonable outputs for inputs it has not been taught how to deal with
  • 6. A neuron: many-inputs / one- output unit  Dendrites receive activation from other neurons  Axons act as transmission lines to send activation to other neurons  Synapses ,the junctions allow signal transmission between the axons and dendrites
  • 7. ANNs incorporate the two fundamental components of biological neural nets: 1. Neurones (nodes) 2. Synapses (weights)
  • 8.  Neurone vs. Node
  • 9.  Synapse vs. weight
  • 10. Neuron consists of three basic components. 1 . Weights 2 . Thresholds 3 . Activation function
  • 11.  Weighting Factors The values w1,w2,…wn are weights to determine the strength of input vector x=[x1,x2,…xn]T  Thresholds The node’s internal threshold is the magnitude offset  Activation Function Performs a mathematical operation on the signal output Most common are linear,threshold,S shaped,tangent hyperbolic function Choice of function depend on the problem solved by the neural network
  • 12. Neural Networks offer improved performance over conventional technologies in areas which includes:  Machine Vision  Robust Pattern Detection  Signal Filtering  Virtual Reality  Artificial Life  and more.
  • 13. Advantages ◦ Adapt to unknown situations ◦ Robustness: fault tolerance due to network redundancy ◦ Autonomous learning and generalization  Disadvantages ◦ Not exact ◦ Large complexity of the network structure
  • 14. Learning the Distribution of Object Trajectories for Event Recognition  Radiosity for Virtual Reality Systems  Speechreading (Lipreading)  Detection and Tracking of Moving Targets  Real-time Target Identification for Security Applications  Autonomous Walker & Swimming Eel
  • 15. Robocup: Robot World Cup Using  HMM's (hidden Markov models) for Audio-to-Visual Conversion  Artificial Life: Galapagos
  • 16. The moving target detection and track methods here are "track before detect" methods.  They correlate sensor data versus time and location, based on the nature of actual tracks.  The track statistics are "learned" based on artificial neural network (ANN) training with prior real or simulated data. (a) Raw input backgrounds with weak targets included, (b) Detected target sequence at the ANN processing output, post-detection tracking not included
  • 17. As part of the research program Neuroinformatik the IPVR develops a neural speechreading system as part of a user interface for a workstation.  A neural classifier detects visibility of teeth edges and other attributes. At this stage of the approach the edge between the closed lips is automatically modeled if applicable, based on a neural network's decision.
  • 18. The system localises and tracks peoples' faces as they move through a scene. It integrates the following techniques: 1. Motion detection 2. Tracking people based upon motion 3. Tracking faces using an appearance model  Faces are tracked robustly by integrating motion and model-based tracking.
  • 19. (A) Tracking in low resolution and poor (B) Tracking two people lighting conditions simultaneously: lock is maintained on the faces despite unreliable motion-based body tracking.
