I am more interested in Learning Neural Network. But because of difficulty in understanding, I really could not make use of its in my application. If we want to learn new technology, I think the good way is to start with some interesting application in which it is used. instead of starting basics and theories.
I knew that neural network is used in Classification application. This topic is interesting to me. So I am going to learn the simple classification example in Neural Network.
In matlab I tried to classification example
In a command window type nnstart
Choose pattern Recognition and classification tool or type nprtool in command window
You may use help. for trying out this example. getting started with neural network –> examples –> pattern recognition and classification
Search Crab Classification example in help file. can be tried out first to understanding the practical application pattern recognition neural network

The AVW1 is available as a replacement part or as needed for continuity or compatibility, but we recommend the AVW200-series interfaces for all new applications.
The AVW200 interfaces are much more accurate and feature a high degree of noise immunity for your vibrating-wire measurements.
The AVW1 provides amplification and signal conditioning for the frequency signal of one vibrating-wire or vibrating-strip transducer. Compatible sensors include pressure, load, strain, or even vibrating wire temperature sensors. The recommended frequency range is 1000 to 9900 Hz (up to 5000 Hz in the CR5000).
- Interfaces one vibrating-wire sensor to the datalogger
- Interfaces both temperature and frequency measurements from vibrating-wire sensors
- Supports a frequency sweep range of 1000 to 9900 Hz
- Can be used in conjunction with an AM16/32B or AM416 multiplexer
