Presentation Transcript

Artificial Neural Network Technology : 

Artificial Neural Network Technology Presented by:Joan Carter Jonathan MacArthurMartin Sand John WellsCharles Shaughnessy Phil Jones

The beginning : 

The beginning Started in the 1940’s Stunted in the 1960’s Here to stay in the 1980’s

What it does : 

What it does Uses non-linear statistical data modeling tools Current computer given step by step instructions Human analysis The computer can learn Optimal solution provided by computer Robot issues

Basic types of applications : 

Basic types of applications Recognition and identification Medical diagnosis Face recognition Assessment Data mining Monitoring and control E-mail spam filtering Process control Vehicle control Forecasting and prediction Financial applications

What is Neural Networks replacing? : 

What is Neural Networks replacing? The hype of the artificial intelligence technology had failed to deliver the expected computing ability for these reasons: The business community increased its collection of data, but the expectation for its usefulness in critical business assessment & decision making was not realized Failure to extract meaning from complex and imprecise data Need to replace the conventional approach to define algorithms to solve problem and make predictions when there are no known solution Sequential batch processing of data is inadequate for the speed at which information is needed

Neural in Business Applications : 

Neural in Business Applications In Medicine Biomedical Systems Instant Physician Electronic Nose

Business Forecasting & Predictions : 

Business Forecasting & Predictions Neural Networks in Marketing Neural Networks in Credit Evaluation Neural Networks in Forecasting Neural Networks in Data Mining

Other Uses of Neural Applications : 

Other Uses of Neural Applications Recognition of speakers in communications Diagnosis of hepatitis Recovery of telecommunication from faulty software Interpretation of multimeaning Chinese words Undersea mine detection Texture analysis Three dimensional object recognition Hand written word recognition

Benefits : 

Predictive ability allows for better control of equipment Example: Pegasus Combustion Optimization Technology Self learning system capable of devising new solutions for improved results Self tuning ensures maximum efficiencies are achieved Less energy used = money saved! Benefits

Cost : 

Pegasus system – NeuSIGHT costs 1/20th the amount to retrofit an existing plant with new hardware. Cost

Business Uses for Neural Networks : 

Business Uses for Neural Networks Recommended business applications for neural networks, based on our research. Preventing and detecting fraud Establishing credit worthiness Predicting default / bankruptcy Marketing applications

Business Uses for Neural Networks : 

Business Uses for Neural Networks Preventing and detecting fraud Neural networks can identify patterns of behavior that have led to fraudulent outcomes in the past. When a similar pattern is repeated, the neural network software flags the event for investigation. As more patterns are identified and additional fraud outcomes are confirmed, the neural network software will begin to learn these patterns and gain human like intuition.

Business Uses for Neural Networks : 

Business Uses for Neural Networks Establish credit worthiness Current credit ratings use a small number of predetermined factors to establish an individuals credit worthiness. Neural networks are able to look for hidden patterns of behavior that may not otherwise be evident to determine credit worthiness. Again, a neural network has the ability to learn and improve its ability to predict over time.

Business Uses for Neural Networks : 

Business Uses for Neural Networks Predicting default or bankruptcy Neural networks have the ability to sort through a large amount of data, including customer credit and payment transactions. Based on this data, the neural networks can look for patterns of behavior that have led to default or bankruptcy outcomes in the past. As the neural network software continues to scan customer behavior patterns, the neural network can flag a customers account when a concerning pattern of credit or payment behavior emerges, allowing the company to intervene before the customer defaults or files for bankruptcy.

Business Uses for Neural Networks : 

Business Uses for Neural Networks Marketing applications Neural networks can look at consumer purchase behavior over time to identify purchase patterns. Tracking customer purchases, the neural network software can predict what the consumer is likely to purchase next. This will allow marketers using neural networks to target customers who are likely to purchase their products next, giving them a competitive advantage.

Vendors : 

Vendors Microsoft (Excel) - NeuralTools NeuNet Pro Calsci - BrainMaker MATLAB - Neural network Toolbox

Product comparison : 

Product comparison NeuralTools – Easy applications, fast learning and good intergation as most companies already use Microsoft. MATLAB Neural nework Toolbox requires MATLAB. This is easy to learn and integrates with major operating systems, but it requires additional training. Calsci – BrainMaker is compatible with Mac and PC, a tailormade system allowing the user to make better and faster decisions.

Prices : 

Prices From free trial versions to $499 and up. Neural Network Toolbox requires MATLAB, more costly to implement if the company does not already use MATLAB. Calsci - BrainMaker

Reference Material - Wiki : 

Reference Material - Wiki Available at http://en.wikipedia.org/wiki/Artificial_neural_network Provides a broad overview of Neural Networks Numerous links to other reference materials for a better understanding of the various types of neural networks available today

Reference Material - YouTube : 

Reference Material - YouTube Presentation of Neural Networks by Google -http://www.youtube.com/watch?v=AyzOUbkUf3M -Future of Neural Networks -Warning: 1 hour long Lecture about Neural Networks http://www.youtube.com/watch?v=6ixqKw7uK6o Prof. Dasgupta, Indian Institue of Technology Warning: 1 Hour long

Reference – Useful Links : 

Reference – Useful Links Digital Signal Processing : By S. Smith -http://www.dspguide.com/ch26/2.htm -Provides a Mathmatical Understanding of Neural Network Structure

Possible future implications : 

For now, only large firms are able to reap the benefits of artificial neural nets In the future, personal computers may be integrated with artificial neural networks Could artificial neural networks make unpredictable situations a thing of the past? Possible future implications

Business Uses for Neural Networks : 

Business Uses for Neural Networks In conclusion: There are many possible business applications for neural networks. Any application that could benefit from tracking past behavior patterns, even hidden behavior patterns, and using them to predict future behavior is a candidate for a neural network. We only explored a handful of possible uses here today. Thank-you for taking the time to listen to our presentation and we hope you have learned just a little more about neural networks and their possible business applications.
