Until now, neural net software has been designed for specialists with advanced knowledge
of neural net technology. They had to learn both an esoteric technology and a new user
interface. Braincel takes a radically new approach:
- It's the first neural-net program embedded in a spreadsheet. The Braincel program is
written in C and implemented transparently in the spreadsheet environment and Microsoft
Windows. It takes advantage of Windows' intuitive, easy-to-use interface and it can be
used by any Excel user.
- It eliminates the need for you to have in-depth technical knowledge of neural nets. To
solve real-world problems, other programs require you to constantly adjust such parameters
as "learning rate," "momentum," and number of "hidden
nodes." Or else you're limited to undemanding "toy" problems.
- To handle this problem, Braincel features a best-net search feature to try out several
nets with different parameters until the best set of parameters is found.
- Other programs use less-accurate integer (whole number) arithmetic. Braincel uses more
precise floating-point arithmetic, which results in more accurate learning and a lower
probability of being trapped in "local minima."
- Braincel uses an advanced algorithm called BackPercolation ("BackPerc").
BackPerc learns up to 100 times faster than the standard Backpropagation algorithm in some
problems, allowing for high-speed, real-time modeling.
- Other neural net software can only accept numbers. Braincel can also accept text values
and blank cells - no reformatting required. For example, a Braincel neural net loan
advisor might use such text values as "excellent loan risk," instead of
requiring the user to convert this into a number.
