### Can someone explain the difference between MCP neurons and Perceptrons?

I am getting confused with the literature. Is a perceptron simply a network of MCP neurons? From what I understand, in 1957 Rosenblatt developed the perceptron based on relaxed constraints from the ...

### Is it possible to detect cats from dogs in image with single layer perceptron?

I want to make a simple application that input is an image and output must be 0 if image is dog and 1 if image is cat. Is it possible to detect cats from dogs in image with single layer perceptron?

### Learning a perceptron from stream data

I want to train a Perceptron using stochastic gradient rulefrom the stream data. I have very limited amount of memory and i can store only $N$ examples. Suppose my population consist of point as ...

### Single Layer Perceptron vs Multi Layer Perceptron

Why the single layer perceptron has a linear activation function while the Multi Layer Perceptron has a non-linear activation function ? What is the potential of the Multi Layer Perceptron respect of ...

### Proof of perceptron convergence theorem for ZERO threshold?

The generalized perceptron convergence theorem is for a defined threshold T. When you do the maths it all comes to an upper bound and a lower bound. The lower bound looks like this! Therefore ...

### Perceptrons: Functions not learnable without bias

I am trying to determine which functions are not learnable without a bias when building a perceptron. The set of functions I need to evaluate is {NOT, OR, AND}. Could someone help interpret these ...

### (Percision & recall) Vs (Accuracy)? which one do I have to consider?

I am running several machine learning classifiers to predict something from my data. If I visualized the precision and recall tables as a result, is it enough to get clear idea about the proposed mdel?...

### Multiple Weighted Hyerplanes to Classify XOR

I learned in class that perceptrons cannot simulate the XOR operation. My professor told me that one fix was to left the points onto a higher dimensional space. That is pretty obvious, you just use ...

### Why do people insist to use the term “multilayer perceptron” instead of “multilayer perceptron network”?

The perceptron model describes a linear classifier. Often people use the term "multilayer perceptron" to describe a feedforward neural network that uses perceptrons. This terminology simply sounds ...

### Are Perceptrons the neural network equivalence of Linear and Logistic Regression?

am I right in the assumption that both linear and logistic regression algorithms can be represented as the simplest form of neural networks,a perceptron, which consists of a two layers, an Input and ...

### Square or circle neural network detection

I am trying to use a simple perceptron to recognize if there is a square or a circle on an image. The images I generated are 300x300 px and I am having issues training the network since the images are ...

### Confusion regarding terminology surrounding perceptron learning

I am having trouble understanding the terminology with perceptron learning. Is my current understanding correct? Let's say I have some data that classifies what type of flower a particular flower is. ...

### Z-score relations to perceptrons

I am learning about preceptrons and my professor noted that z-scores are a commmon pre-processing step to normalizing input variables. Following this, I am having trouble understanding why z-scores ...

### Question about simple perceptron code

I'm reading through Sebastian Raschka's Python Machine Learning, and I see something confusing that is not explained in the text. In the code on this page: https://github.com/rasbt/python-machine-...

### what is difference between multilayer perceptron and multilayer neural network?

When do we say that a artificial neural network is a multilayer Perceptron? And when do we say that a artificial neural network is a multilayer? Is the term perceptron related to learning rule to ...

### What is a homogenous half-space?

I can't think of any definition for half-space that would involve some sort of quantity not being homogenous. This term is used in the paper Robust Concepts and Random Projection in the following ...

### How do I prove that the Perceptron bound for mistakes is tight?

How do I prove that the Perceptron bound for mistakes is tight? I need to prove that for any amount of given data points, the total amount of updates (mistakes) that the algorithm will make is \$\frac{...
