Binary Cross-Entropy

Binary Cross-Entropy

A loss function utilised in binary classification tasks is called binary crossentropy. These are assignments that offer a single, two-option response to a query (yes or no, A or B, 0 or 1, left or right). As in multi-label classification or binary image segmentation, multiple independent such problems can be addressed simultaneously.

According to formal definitions, this loss is equivalent to the mean of the categorical crossentropy loss on numerous two-category tasks.

Loss function introduction
Let's first learn the Loss function before moving on to Log Loss. Consider the following scenario: You believe your machine learning model has identified cats and dogs with success, but how do you know this is the optimal outcome?


Here, we're seeking for measurements or a function that can help us improve the performance of our model. The loss function indicates the accuracy of your model's predictions. Loss will be at its lowest if model projections are closest to the actual values, and at its highest if predictions are farthest from the original values.

Tanh Activation Function

Image
With a difference in output range of -1 to 1, the tanh activation function is remarkably similar to the sigmoid/logistic activation function, and even has the same S-shape. The larger the input (more positive), the closer the output to 1.0, and the smaller the input (more negative), the closer the output to -1.0. Mathematically it can be represented as: The following are some of the benefits of using this activation function: We can simply map the output values as strongly negative, neutral, or very positive because the tanh activation function's output is Zero centred. Because its values range from -1 to, it's commonly utilised in hidden layers of neural networks. As a result, the hidden layer's mean is 0 or extremely close to it. It aids in data centering and makes learning the next layer much simpler. To understand the tanh activation function's limits, look at its gradient. As you can see, it, like the sigmoid activation function, has the problem of vanishing gradi

Sigmoid Activation Function And Its Uses.

Image
The sigmoid activation function is a mathematical function commonly used in artificial neural networks and machine learning models. It maps the input values to a range between 0 and 1, providing smooth and continuous output. The sigmoid function is defined as: σ(x) = 1 / (1 + e^(-x)) Where: x is the input to the function e is the base of the natural logarithm (approximately 2.71828) The sigmoid function has an S-shaped curve that increases from 0 to 1 as the input value increases. It has the desirable property of being differentiable, which is a valuable for training neural networks using gradient-based optimization algorithms like backpropagation. One of the main applications of the sigmoid function is in binary classification problems, where the goal is to assign inputs to one of two classes. The sigmoid function is commonly used as the activation function in the output layer of a neural network for this purpose. The output value, between 0 and 1, can be interpreted as the pro
