Awesome App
I love how easy it is to use. I'm not a tech savvy guy and this has given me absolutely no problems.
Honestly it does what i need it to do. NO complaints

Very easy to use
That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same
That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.

I like that I don not have to decide how big the text box needs to be, it does it automatically. I use it for work to fill out my time sheets or edit PDF files and it works like a charm.

I needed to print out the forms for a passport. PDFiller was where I was sent to do this. Perfect! I am an 83 year old senior and using a filler is not going to be a part of my life. I need to cancel my 30 day free trial. Please help me to do this. It appears that you have a very successful business, with good reason. Thank you for your service and helping me in canceling my account.Constance Heidt

So far, I like it.
If this app does as it looks so far, I can cancel 2 subscriptions for a pdf editor and digital signature app. This will consolidate our work into 1 location. I'm still learning the app but so far, I like it.

What is feature transformation?
Feature transformation (FT) refers to family of algorithms that create new features using the existing features. These new features may not have the same interpretation as the original features, but they may have more discriminatory power in a different space than the original space.
What is feature creation?
Feature engineering, also known as feature creation, is the process of constructing new features from existing data to train a machine learning model. Typically, feature engineering is a drawn-out manual process, relying on domain knowledge, intuition, and data manipulation.
What is feature generation?
Feature generation is the process of creating new features from one or multiple existing features, potentially for using in statistical analysis. This process adds new information to be accessible during the model construction and therefore hopefully result in more accurate model.
How do you become a feature engineer?
