So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!

Easy to use, but sometimes doesn't show exactly what I need with form being listed under another name or title (e.g. a search for DA 31 gave me the AR 600-1 132 page doc but not the Leave and Pass Form).

Very professional and good customer support
I forgot to cancel the auto renewed subscription after my free trial and they got back to me within a day and were also very responsive. I got refunded immediately even though it was my fault for not cancelling.

Should I normalize or standardize?
In the business world, “normalization” typically means that the range of values are “normalized to be from 0.0 to 1.0”. “Standardization” typically means that the range of values are “standardized” to measure how many standard deviations the value is from its mean. However, not everyone would agree with that.
Is standardization the same as normalization?
The terms normalization and standardization are sometimes used interchangeably, but they usually refer to different things. Normalization usually means to scale a variable to have a value between 0 and 1, while standardization transforms data to have a mean of zero and a standard deviation of 1.
Why do we standardize or normalize data?
Standardization: Standardizing the features around the center and 0 with a standard deviation of 1 is important when we compare measurements that have different units. Variables that are measured at different scales do not contribute equally to the analysis and might end up creating a basis.
What is normalization and standardization in machine learning?
In statistics, Standardization is the subtraction of the mean and then dividing by its standard deviation. In Algebra, Normalization is the process of dividing of a vector by its length, and it transforms your data into a range between 0 and 1. Originally published at https://www.safacreations.net.
What is standardization in ML?
Data standardization is the process of rescaling one or more attributes so that they have a mean value of 0 and a standard deviation of 1. Standardization assumes that your data has a Gaussian (bell curve) distribution.
What is the difference between normalization and scaling?
The difference is that, in scaling, you're changing the range of your data while in normalization you're changing the shape of the distribution of your data.
Should you normalize audio?
When to Normalize Normalization can be a great tool for quickly boosting the level of a sample or recording without worrying about clipping. Your audio should come out sounding the same as it went in! The ideal stage to apply normalization is just after you have applied some processing and exported the result.
What happens when you normalize audio?
To normalize audio is to change its overall volume by a fixed amount to reach a target level. It is different from compression that changes volume over time in varying amounts. It does not affect dynamics like compression, and ideally does not change the sound in any way other than purely changing its volume.
