| body | "Although people who live close to the sea can enjoy beautiful beaches everyday, swim or ride whenever they want and drink coctails while having wild parties in night clubs, there are a few bad things about it. Wildfires are one of them. I'd like to point out that wildfires are not just problem of people who live close to the sea, because they can happen anytime and anywhere.

Even though they can be caused accidently, many researches have shown that most fildwires was caused on purpose. Being a pyromaniac is a kind of mental illness.

Considering that in my area (Dalmacija, Croatia) you can see wildfires everyday, watch canadairs flying around and read in news that many homes have been destroyed by fire, the only thing I'd like to say is: STOP WILDFIRES IN CROATIA!

| body | "# Autoencoders
---
##### Sorry I haven't posted in a long time, but I've been working on a model for the zillow kaggle competition. (Kaggle is a website which hosts datasets and competitions with prizes!) Autoencoders are basically feed forward neural networks which is trained on the identity and which has small hidden layers...Here's a post explaining what I know and asking a question for brownie points!
---
<h5>
So anyway...look at this picture of an autoencoder!
https://upload.wikimedia.org/wikipedia/commons/2/28/Autoencoder_structure.png
Autoencoders are simply feedforward neural networks as I've described in <a href="https://steemit.com/mathematics/@jackeown/introduction-to-machine-learning-training-neural-networks">previous posts.</a>.
HOWEVER this one is trained on data where the output is the same as the input...in other words, you are training a neural network to predict the identity on a set of data!
This sounds stupid and counter-intuitive at first glance...but it can help you do feature detection and/or dimensionality reduction. Here's how...
It's remarkably simple...you just make the middle layer of the network have very few neurons. In order to learn how to reproduce the input on the other side, it has to learn a compressed representation in that small hidden layer! This is the key insight!
</h5>
---
### Let me know if you have any questions about how this works!
### Meanwhile...I have a question for anyone willing to answer: Is it common practice to pass the hidden representation layer through a nonlinearity like sigmoid as you would any other hidden layer? Or is it more common to have the hidden representation layer be linear?" |
