Deep Learning 4.1 Concept of Deep Learning 4.2 Introduction to Neural Networks 4.3, Types of Deep Learning models 4.4 Deep leaning applications Deep learning is a subset of machine learning that involves the use of artificial neural networks with multiple layers (hence “deep”) to model and understand complex patterns in large amounts of data. Tt enables machines to learn from vast datasets by automatically extracting features and representations, which makes it particularly effective for tasks such as image recognition, natural language processing, and speech recognition. Deep learning models are designed to learn hierarchies of features, where each layer of the network captures increasingly abstract representations of the input data. This capability allows deep learning to achieve high levels of accuracy in tasks that require the understanding of intricate relationships and structures within the data. The simple machine learning algorithms described in this chapter work very well on a wide variety of important problems. However, they have not succeeded in solving the central problems in AI, such as recognizing speech or recognizing objects. The development of deep learning was motivated in part by the failure of traditional algorithms to generalize well on such AI tasks. ‘4.1 Concept of Deep Learning : The definition of Deep learning is that it is the branch of machine learning that is based on artificial neural network architecture. An artificial neural network or ANN uses layers of interconnected nodes called neurons that work together to process and learn from the input data, Deep learning is an emerging field that has been in steady use since its inception in the field in 2010. It is based on an artificial neural network which is nothing but a mimic of the working of the human brain, Just like the ML model, the DL model requires a large amount of data to leam and make an informed decision and is therefore also considered a subset of ML. This is one of the reasons for the misconception that ML and DL are the same. However, the DL model is based on artificial neural networks which have the capability of solving tasks which ML is unable to solve. The future is driven by DL models Without DL, Alexa, Siri, Google Voice Assistant, Google Translation, Self-driving cars are not possible,peep Learning 3 Machine Learning Deep BETO: Artificial Intelligence Here’s a concise, comparison between machine learning and deep learning: .

Each layer processes data and passes it to the next layer, helping the system learn complex patterns. Layers: - Input Layer: Where data enters the network, - Hidden Layers: These layers perform calculations and transformations. Deep learning typically uses many hidden layers. - Output Layer: Produces the final results or predictions. Activation Functions: These functions decide whether a neuron should be Pr 2 4.2 activated or not, introducing non-linearity into the model. Common examples include ReLU (Rectified Linear Unit) and sigmoid. How It Works To train a deep learning model, you typically follow these steps: Collect Data: Gather a large dataset relevant to the problem you want to solve (e.g., images, text). Train the Model: The model learns from the data by adjusting its internal Parameters through a process called backpropagation, where it minimizes errors in its predictions. Evaluate Performance: After training, the model’s accuracy is tested on new, unseen data to see how well it performs.

Each node in this layer corresponds to a feature or attribute of the data. Hidden Layers : These layers are between the input and output layers. They perform computations and transformations ‘on the input data. A network can have one or more hidden layers, which is what defines “deep learning” when multiple layers are present. Output Layer : The final layer that produces the output. The number of neurons in this layer depends on the type of task (e.g., classification, regression). Neurons Each neuron performs the following igence, cnabling computers to recognize Activation Output “g=g(w-x+b) functions: Weighted Sum: The neuron calculates a weighted sum of its inputs. Each input is multiplied by a weight, which signifies its importance. Activation Function: The weighted sum is passed through an activation function, which determines the neuron’s output. Common activation functions include: - Sigmoid: Produces an output between 0 and 1. - ReLU (Rectified Linear Unit): Outputs the input directly if it is positive; otherwise, it outputs zero. = Tanh: Produces an output between -1 and 1. What is Neural Net ? - A neural net is an artificial representation of the human brain that tries to simulate its learning process. An artificial neural network (ANN) is often called a “Neural Network” or76 Fundamental of Aq simply Neural Net (NN). Traditionally, the word neural network is referred to a network of biological neurons in the nervous system that process and transmit information, Artificial neural network is an interconnected group of artificial neurons that uses a mathematical model or computational model for information processing based on a connectionist approach to computation. ‘The artificial neural networks are made of interconnecting artificial neurons which may share some properties of biological neural networks. + Artificial Neural network is a network of simple processing elements (neurons) which can exhibit complex global behaviour, determined by the connections between the processing elements and element parameters, Here’s a comparison of artificial neural networks (ANNs) and the human brain, focusing on terminology: The structure of artificial neural networks is inspired by biological neurons.

Output Synaptic Weights The McCulloch-Pitts neuron consists of several key components: Inputs : The model accepts multiple binary inputs (0 or 1), which represent signals from other neurons or sensory inputs. Weights : Each input is associated with a weight, although in the original model, these weights are implicitly considered as being equal (typically binary: either present or absent). Summation : The inputs are summed together, resulting in a total activation value. Threshold : A threshold value is defined. If the summed inputs exceed this threshold, the neuron “fires” and Produces an output of 1; otherwise, the output is 0, Functionality The McCulloch-Pitts neuron operates based on the following logic: Activation Function: The output y is determined by the equation: Fe { if D(w, x)= eee 0 otherwise Activation Function Yk Here, wyepresents the weights, xthe input values, and the sum is taken over all inputs. ~ Binary Nature: The model operates in y binary fashion, meaning it can only produce outputs of 0 or I. This characteristic aligns with the idea of simple decision-making processes. 3. Logic Gates The McCulloch-Pitts neuron can be used to model basic logical functions. By configuring the inputs and thresholds, it can represent various logic gates: - AND Gate: Requires all inputs to be 1 to produce an output of 1. = OR Gate: Requires at least one input to be 1 to produce an output of 1. - NOT Gate: Inverts the input; if the input is 0, the output is 1, and vice versa. 4, SIGNIFICANCE - Foundation of Neural Networks = ‘The McCulloch-Pitts model was pivotal in establishing the concept of netione as computational units, influencing a developments in artificial neut networks,80 Fundamental of 4 |" - Theoretical Framework : It provided a simple framework to understand how networks of neurons could be used to perform complex computations. Limitations While the McCulloch-Pitts neuron was ground-breaking, it has several limitations: - Binary Inputs and Outputs : The binary nature restricts its ability to model more complex, continuous-valued functions. Static Weights : The original model does not incorporate learning or weight adjustment mechanisms. - Lack of Complexity : It cannot represent more complex functions requiring non-linear combinations of inputs. 1, Feedforward Neural Networks (FNN) : Conclusion : The McCulloch-Pitts neuron is a funda. mental concept in the history of artificia, intelligence and neural networks, By simulating basic logical operations ang introducing the idea of neurons as computational units, it paved the way for more advanced models and techniques jn the field.
