7:40. The bottom right neuron is supposed to be inverted. 2 black on top and 2 white on the bottom. The negative weights should actually be positive weights.

Fourier series comes to mind. Basically, add a bunch of simple but different curves together to get one complicated but continuous curves.

1:20:40 Since this course is about learning algorithms this is important to classification. Vector: noun Mathematics. 1: a quantity possessing both magnitude and direction, represented by an arrow the direction of which indicates the direction of the quantity and the length of which is proportional to the magnitude. 2: such a quantity with the additional requirement that such quantities obey the parallelogram law of addition. 3: such a quantity with the additional requirement that such quantities are to transform in a particular way under changes of the coordinate system. Biology. 1: an insect or other organism that transmits a pathogenic fungus, virus, bacterium, etc. 2: any agent that acts as a carrier or transporter, as a virus or plasmid that conveys a genetically engineered DNA segment into a host cell. Computers. 1: an array of data ordered such that individual items can be located with a single index or subscript. verb (used with object) Aeronautics. 1: to guide (an aircraft) in flight by issuing appropriate headings. Aerospace. 1: to change the direction of (the thrust of a jet or rocket engine) in order to steer the craft. ... I am tempted to say Physics would include a unit Physics 1: a quantity possessing magnitude, direction and unit.

Seems like neural net teaching comes in two forms - math or python libraries. It'd be cool to see an intermediate form - some code that implements the math but isn't a library.

@3.56, the activation function shown is tanh (-1 to 1) not a sigmoid/logistic (0 to 1).
abcd efgh
abcd efgh Yıl önce
Essentially, the sigmoid function is equivalent to a tanh function just multiplied by some factor (as well as the argument)
Vishnuvasan Srinivasan
but the activation function can be anything right!!! It can be anything related to what the input is all about like: ReLU, Sigmoid, tanh, etc...

I want to ask that the weights in neural network so the linear relationship between input and output but then we apply non linear function to get a non linear output but if that then we didn't use non linear function directly on the sum of inputs why apply weights and here ,are weights showing the relation between input and non linear output or what.what is the effect of weights on the non linear output and why use weights and non linear function together.

First 30s wrong example but good video in general. Yes, you can simply detect what pixels are dark, what are lighter, there is function for that. Also 4 pixels is bad example because you could create like 8 if statements define tolerance (same tolerance as in Photoshop which is distance between colors) and it would outperform every model.

TheZyreick
TheZyreick Yıl önce
If you are needing data because you lack data, but you have very good base data for what you do have. You can always simulate data to use for training as long as you do research on what the realistic standard deviations are for that data type. Language is difficult to simulate this way though because variations can come out as complete jibberish very quickly
TheZyreick
TheZyreick Yıl önce
@Aiden Still or you can do the smart thing and use the free libraries available which a large company and hundreds of people spent millions of dollars and thousands of hours to create, so you don't need to spend millions of dollars and thousands upon thousands of hours yourself doing it
TheZyreick
TheZyreick Yıl önce
@Aiden Still what they actually mean is no, since the other replies aren't being helpful You will need to record every single word spoken for the language you're training it for, these will need to be perfectly grammatically accurate spoken recordings if they're your base case. Next you'll need a way to simulate these in subtle variations to compensate for different accents and pronunciation of those words unless you want to go record all that yourself as well in order to create the data to train your algorithm on All machine learning is using algorithms to analyze data and produce a desired result from that data If you do not have any data, you cannot train a machine learning algorithm

the graphs from 40:00 foward makes no sense to me, how can you have 2 values and not make a straight line? you have y output and x input and you get waves? that graphic makes no sense on what you are talking about... unless if you have a diferent value called repetition or time, but still the first ones without the multiple nodes will also make waves since you are adjusting the values right? I dont understand it...

0:40 if you tried making a rule you wouldn't be able to do it. Why? Isn't the rule pretty clear? If only the 2 top or 2 bot are black, it's horizontal. If only the 2 left or 2 right are black, it's vertical. Every other composition where 2 are black is diagonal. If 3 are black, it's L. This just seems programmable. What am I missing?
