A Feature Store is a data management layer for machine learning features. ML features are measurable properties of phenomena under observation, like raw words, pixels, sensor values, rows of data in a data store, fields in a CSV file, aggregates (min, max, sum, mean), or derived representations (embedding or cluster).
The Feature Store for machine learning is a feature computation and storage service that enables features to be registered, discovered, and used both as part of ML pipelines as well as by online applications for model inferencing.

Classification Losses 1. Binary Cross-Entropy Loss / Log Loss This is the most common Loss function used in Classification problems. The cross-entropy loss decreases as the predicted probability converges to the actual label. It measures the performance of a classification model whose predicted output is a probability value between 0 and 1.
Data Size. Both Machine Learning and Deep Learning are able to handle massive dataset sizes, however, machine learning methods make much more sense with small datasets. For example, if you only have 100 data points, decision trees, k-nearest neighbors, and other machine learning models will be much more valuable to you than fitting a deep neural ...

Online learning is a paradigm shift because it allows to change the way we think about machine learning deployment. In addition to making predictions for new data, an online model is also able to learn from it. Indeed, the predictions and learning phases of an online can be interleaved into what is sometimes called the kappa architecture.
