On Making Videos

Here is what i use to make my videos:


1. CamStudio. This is a nice free and open-source desktop video capture program. Make sure to use their Lossless Codec, and go with these settings:

Set Keyframes Every 30 frames
Capture Frames Every = 50 milliseconds
Playback Rate = 20 frames per second
Video codec: CamStudio Lossless Codec
Quality: 70%


2. Handbrake Video Transcoder. This will help you to shrink videos before uploading them to Youtube. It is free and open source. You can cut the size of a video 10x and it will still look & sound good.


3. A Blue Microphones Snowball USB Mic. About $65

4. An Acer Aspire 5742 Laptop (Core i3, 8GB RAM). I like this laptop for the following reasons:

• got it at Wal*Mart for $369 (plus $70 for the extra RAM)
• built-in number pad
• built-in high-def web cam
• gesture mouse pad
• hdmi output
• decent battery time
• light

The only problem with it is the crappy built-in microphone, hence the Snowball.

Text Analytics with RapidMiner Part 6 of 6 - Applying the Model to New Documents

After my last series, I got a lot of questions about how to apply a model to new data, so here is the real final installment in the series.

I show how to save a wordlist and model to the repository. I use them later to read the wordlist and model and apply them to new documents that RapidMiner hasn't seen before. It correctly labels 11 of the 12 documents.
