Ensure that numberic values are between 0 and 1

Hello,

To use Brain.js, I need to convert numeric values to 0 and 1. But I haven’t found a good solution to convert numeric values from large files. For example, I struggle with this dataset:

"Channel": 2,
"Region": 3
"Fresh": 12669,
"Milk": 9656,
"Grocery": 7561,
"Frozen": 214,
"DetergentsPaper": 2674,
 "Delicassen": 1338

Sometimes, I read that people divide values by 10, 100 or 1000, but I doubt it’s a relevant solution. Do you have ideas ?

Thank you,

I think what Robert was suggesting was to find the largest value for each thing beforehand. Snippet:

let maxChannel = 0;
// ... and all the other properties
customers.forEach(customer => {
    if (customer.Channel > maxChannel) {
        maxChannel = customer.Channel;
    }
    // ... and all the other properties
});

const customersData = customers.map(customer => {
    return {
        input: {
            ch: customers[i].Channel / maxChannel,
            ...
        }
    }
})

That will ensure that each value is between 0 and 1, and that the largest value for each property is exactly 1.
