What is the need of cross validation in machine learning modeling? Cross validation is used to better utilize the input data to ensure the model performance. The input data will be divided into many subsets and train the machine learning model on all the subset except one among them. One subset will be kept as …
People from Science, Technology, Engineering and Medicine (STEM) fields often have to deal with scientific charts and graphs. They might use it to communicate their findings as well as learn the latest findings from their peers. Creating quality scientific plots is an important skill for the researchers in STEM fields. The most frequent scientific plots …
Technical definition Bias is a systematic error that happens during the machine learning model due to the incorrect assumptions taken during the training process of the machine learning model.

Differentiate between local optimization and global optimization Optimization is a process of assigning a set of inputs to an objective function that can extract the best possible output from the objective function. Local optimization tries to find extrema points, i.e., maxima or minima of the objective function in some specific or predefined region of the …
The author started to think about this topic when she as a teacher of 7th grade noticed why all her students cannot perform well in basic mathematical topics in 7th grade. She started to research by observing who performs best in some situations and why? She studied different situations such as which person survives a …

Explain label encoding and one hot encoding, Explain how the dimensionality of a dataset is affected with these methods in machine learning Machine learning algorithms can understand only numbers. Often, the dataset consists of categorical and numerical features. We need to convert the categorical features to numerical features for the machines to understand. This process …
Like many of you, I too used to write/set resolutions, mostly around my birthday or New year and used to get disappointed in consequent days with the broken resolutions. The realisation that I am not yet the person I actually want to be or the feelings that my life is still floating because of something …
