An ESN is a recurrent neural network with many layers and fixed weights. There are several differences. An ESN has a cycle that means witin the network there are backwarded connections. Withn a FF NN there are only feedforwad connections. Within a FF NN all weights are trained. Within an ESN only output weights are trained. An ESN can produce an output without any input. A FF NN needs an input to produce an output.

ESN are different to FFNN in so far that they consist of a reservoir of hidden neurons, which may be connected recurrent, as opposed to having a feed forward architecture. Here, the inputs are connected to the recurrent dynamic reservoir, whereas the DR is connected to the linear output layer. The Output layer may be again connected to the DR, whereas during training only weights of the last layer are learned. Weights of the DR of the ESN are thus initialized and never learning, although since have been extended to minimal complexity architectures.

ESN are recurrent neural networls with a large reservoir (or echo chamber) with many nodes (recurrent). The weights are learnt only for the connection between this reservoir and the output layer. The weights are not learnt for the nodes inside the reservoir. The main idea is that during training, the input layer cuases the states inside the reservoir to behave in caertain way, and the weights in the output layer is adjusted to match this and the labelled output. FFNN are feed forward networks, i.e., they do not have any recurrent connections, which is the main difference with respect to ESN

ESNs are a special class of recurrent neural networks. In contrast to ff they also allow backward node connections and thus are able to memorize data. They are defined by: $xi$ input i, $yi$ output i, a dynamic resaviour, and weights connecting all the components. The dynamic resaviour is generated randomly and fixed. Its topology including weights is never changed. Only the weights between output layer and dynamic resaviour are changed during training. Because the dynamic resaviour allows all kinds of connections between its nodes it can contain memory that is able to remember data. It also has a spectral radius.

An ESN is a recurrent ANN with randome, sparse and fixed interneuron connections in the hidden layers. Just the output layer weights get trained, because the network itself is so complex, it can model very much. If the training was not successful we can just create a new randome ESN. Training an complete ESN would by very complex and would take very very very long. A FF NN is not recurrent (no feedback) and all its weights get trained and most of the time the interneuron connections are not sparsly.

A Echo State Network is a RNN, is has a dynamical reservoir of neurons which are connected with each other and itself. the DR typically consists of more that 100 neurons. The outputlayer consists of linear readouts of the DR. So a neuron in the output layer sums up the weighted behaviours of the DR neurons. The DR is randomly initialised and only the output layer is trained by supevised learning. The main Diffrence is that ESN is a RNN. In contrast to FFNN it can resemble any dynamical system. Usually it is used for time series prediction.

Echo State Networks are a type of recurrent neural networks, where the input layer is interconnected to a reservoir (a random initialized group of neurons with also random interconnections), and this reservoir is connected to the output. The reservoir will not be adjusted, but the output weights. The output weights can also have recurrent connections with the reservoir. The states on the reservoir neurons will be calculated, and with these states and the output weights, the output will be extracted. The main difference with the Feed Forward Neural Networks (FF NN) is that in the FF-NNs there's no recurrency, so the input values will be passed to the next layer.

- In the ESN we have a huge recurrent network which is called "Dynamic Reservoir(DR)" and we have an output layer connected to this DR and we will train the network by adapting and manipulating the connection weights just to the output layer - Unlike a feedforward network in a ESN because of the DR we have at least one loops that returns the output of a neuron with some time delay therefore we have memory in our network but in FF NNs we don't have any memory

ESNs are a form of recurrent neural networks with a least one recurrent input. The ESNs are reservior computers which have memory and can be activated without the inputs.

The basic idea of ESNs is to use a large, random, fixed recurrent NN (referred to as dynamical reservoir) and to train only connections from the reservoir to the output. The main difference to FF NN lies in the recurrent part of the network, where back passes are built in, giving feedback previous layers. It is not possible to maintain the reservoir beforhand so it suits the given problem. There is a lack of investigation of reservoir construction.

Echo state network provides structure and supervised learning for recurrent neural networks. It mainly 1) Directs the fixed, large reccurent neural netorks by providing an input stimuli and also fix a response signals to the neurons which are present inside the reservoir(Pool of neurons) 2) It can be directed to get the desired response by the trainable linear combiner of the response signals. Unlike FF NNs, ESN's have memory. They can be also activated without an input stimuli, whereas in case of FF NN, they require a external stimuli so that they are activated. Also the neurons needs to connected in one full cycle.

ESN are another implementation of RNNs where training method is completely different. They comprise of a dynamic reservoir with fixed hidden to hidden connections which makes up an RNN with sparse connetivity. Only the output weights which connect the dynamic units and the output of the reservoir are trained using error, unlike RNNs, where the hidden weights are also trained. ESNs are less compuationaly expensive since they can be easiliy trained with experimentation .However, RNNs use much less hidden units compared to ESN for a similar task.

CNN learn on grid data (images, 3d volumes) using filters instead of matrix multiplication. Here, the filters are convoluted with the input in the Convolution layer per neuron, where we slide the filter (defined by fiter size $S\times S$) over the input with a stride (step size), and optional zero padding. Strictly speaking, since for RGB images we are working have three color channels, we work with volumes of filters (For example for RGB images of size $32\times 32\times 3$, a filter of window size $S=5$ has the dimensions $5\times5\times3$). Instead of learning a volume of weights for each convolution step, we share weights, considering that one feature detected in one part of the image may be of interest in another part. Then, we apply a nonlinearity, commonly the ReLu activation, as to introduce nonlinearity into our model. To reduce spatial size of our input, we can either use higher strided convolutional layers or pooling layers, for example the popular max pooling layer, where the maximum value over a subvolume is picked. These layers are then stacked, while in the last layers fully connected neurons are typically used to reduce data to for example a classification vector.

A convolutional neural network consits of convolutional layers. A convolutional layer applies one or multiple kernels (matrix) to an input vector/matrix (typically image) instead of connecting all single inputs of the input vector to the next layer with seperate weights. Instead in training only the kernel is updated. After a convolutional layer there is typicall a pooling layer. Given a window size it reduce the dimensional size of the output of the convolutional layer by using e.g. max or avg pooling. Afterwards the activation layer applies an activation function to the output of the pooling layer.

CNN comprises of multile layers of neurons which perform specific tasks. The initia layer is the convolution layer which performs convolution of the input with the elements of a given kernel. Simpler tasks such as edge detectoíon are performed. Detector layer forms a seconf layer here the output of convolution layer if fed through an activation function such as ReLU. Further, the data is pooled in the pooling layers where downsamping is done to reduce dimensionaity. These layers are repeated to perform more complex feature extraction operations.

A CNN is a neural network that replaces matrix multiplication with a mathematical operation called convolution in one or more layers. The main idea behind the structure of a CNN is to replace the activation of neuron with a flipped filter (Convolution layer) and then apply another function called pooling to adust the output further.
