It is called Adaptive Boosting as the weights are re-assigned to each instance, with higher weights assigned to incorrectly classified instances. What this algorithm does is that it builds a model and gives equal …PandasAI is a Python library that extends the functionality of Pandas by incorporating generative AI capabilities. Its purpose is to supplement rather than replace the widely used data analysis and manipulation tool. With PandasAI, users can interact with Pandas data frames more humanistically, enabling them to summarize the data effectively.These methods are usually computationally very expensive. Some common examples of wrapper methods are forward feature selection, backward feature elimination, recursive feature elimination, etc. Forward Selection: Forward selection is an iterative method in which we start with having no feature in the model.Step 1: Calculate the probability for each observation. Step 2: Rank these probabilities in decreasing order. Step 3: Build deciles with each group having almost 10% of the observations. Step 4: Calculate the response rate at each decile for Good (Responders), Bad (Non-responders), and total.

Nov 17, 2023 · A sequential chain merges various chains by using the output of one chain as the input for the next. It operates by executing a series of chains consecutively. This approach is valuable when you need to utilize the result of one operation as the starting point for the next one, creating a seamless flow of processes. To give a gentle introduction, LSTMs are nothing but a stack of neural networks composed of linear layers composed of weights and biases, just like any other standard neural network. The weights are constantly updated by backpropagation. Now, before going in-depth, let me introduce a few crucial LSTM specific terms to you-.Gradient descent is a first-order optimization algorithm. In linear regression, this algorithm is used to optimize the cost function to find the values of the βs (estimators) corresponding to the optimized value of the cost function.The working of Gradient descent is similar to a ball that rolls down a graph (ignoring the inertia).I am Deepanshi Dhingra currently working as a Data Science Researcher, and possess knowledge of Analytics, Exploratory Data Analysis, Machine Learning, and Deep Learning.
