Neural Networks Practical


I was working on my Neural Networks practical today,trying to create a neural network that would correctly identify an image of a handwritten digit. One part of the practical asked me to construct some features of an image and train a neural network on these features. Creating these features is somewhat of an artform and usually requires lots of domain knowledge,experience en creativity. But the lecture notes also contained a few slides about something called an autoencoder,which is apparently able to discover features by itself. There is an article from Science magazine online where somebody has used such an autoencoder to compress a 28×28 image to a feature of only thirty numbers.

The basic idea is shown in the figure on the right. An image is given to a neural network with 2000 hidden nodes and 1000 output nodes. The output of these nodes is then given to a neural network wit only 500 output nodes,etc.,etc. At the end of encoding,we end up with 50 values. These 50 values can be decoded by putting it into a mirrored (in terms of architecture) version of the encoder. If all goes well,the decoder ends up with something equal (or very similar) to the input image.

Brokerage Account

Yes, you do need to open a brokerage account and fund it. If you didn't, you wouldn't be trading anything.
You can start a standard account with a $2,000 minimum. You can start a mini account with $300 minimum.
Forex trading is great, and in my opinion, much safer and easier than trading stocks or commodities.
I highly recommend purchasing a course, and learning before you go into it. You are much more prepared, and really know what you are doing when you start trading with real money.
There are a few different companies out there that teach you how to do it. It is important to get a good education. I checked them all out, and actually, the most expensive are not the best.
is the one that I used.

I would be happy to, but someone asked me that before, and when I answered, it was flagged. I am not sure, but I think that stock traders don't like Forex trading.
I am not sure why that is. The Forex market is much bigger, and it is recession proof. There will always be banks and businesses trading money. Chrysler, last year, made more money trading Forex than they did selling vehicles. This market is also less risky, with enormous liquidity, and no slippage. Forex has low transaction costs, much higher leverage, and low account minimums.
I just think you need to know what you are doing, and for most of us, it takes education. I didn't go and work in a hospital until I went to nursing school, and prepared myself. I wouldn't risk my money until I learned how to trade it....

I am trading Forex, from the computer at my home. I am making several thousand a week, but I am only trading one lot. Several friends who have more money than I are trading more lots, and are making way more money than I.
It is good for me, and I am building my account, and when I have more money, I will trade more lots.
It is not something you can just go and do, you have to learn about it, or you will waste your time and your money.
I studied for about six weeks, and during that time, I practiced on a demo account.
I took live classes online, and they were great. You can take them as many times as you like. I paid $2000 for the beginners and advanced classes, but you can start with $995 for the beginners class. I figured it is less than I would spend for a...

Look i will give you the truth about trading but you must realize that day trading the Stock market is a huge risk and so that is why I have switched (three years ago) to the Forex or foriegn Currency Exchange,I am by no means a professional but I consider myself seasoned. I tried like crazy to make money when I first started....I spent over Five Grand on educational classes and seminars teaching this very interesting business and finally began to earn a living and finally some real money. there is a huge learning curve, but if you want I will give you my secret weapon which has saved many of my friends and family countless hours and most often a lot of money and head so if you want to see how and what I do now, let me know.

Jack, thanks for introducing yourself!

Hi Jack,
I am one of those rare people who LOVE lawyers (I was a legal assistant for YEARS in my 20s and also worked in word-processing when I was putting myself through design school).
You're right about the stress, though. Lawyers work lots of hours and (especially in a firm) are expected to pretty much give up their lives for several years.
Sounds like you have a LOT of other projects, though.
That's awesome.
I love sea kayaking. Used to go once in awhile in Seattle. And skiing (although I switched to snowboarding when I moved to Montana and don't think I'll go back to 2 sticks again!).
Day trading (I do Day Surfing) is fun. Do you trade Forex? I'm learning that right now.
Have a GREAT winter.
