What are image layers called?
Channels - these are layers of pixels that represent colors
What are filters in image processing
These are process that modify the pixels in an image. These filters are one or more arrays called Filter Kernals
What is classification
a ML technique to predict which category or class something belongs too.
with a custom vision model what information is returned
Bounding box
Class Name
Probability score
What are the types of resources for image classfication
Custom vision - you create a model via training on your data.
azure ai service - a general resource that uses Azur AI custom vision and other ai services.
what is Precision
the percernt of class predictions made that were correct
what is recall
percent of class predictions did the model correctly identify
What is AP or Average Precision
Overall metric that takes both Precision and Recall
What are Natural Language tokens
words broken into chunks. Short words is one token but larger ones can take more
What is Azure AI Search
a PAAS platform that extract s from various structured, unstructured and non-structed data sources
what are AI search features
any source that you idenfity
full text and analytics
ai powered search
multi lingual
geo-enabled (for location)
configurable user experience (auto complete, autosuggust, pagination,highlighting)
what are search skills
A skillset defines the operations that extract and enrich data to make it searchable
What are some search Skills
Built in skills include: Key phrase, text translation, Image analysis and optical character
what is a search index
A contrainer of searchable documents - a json table with each row being a document, and each field fields in a doc
what is the index schema
the structure of the data in the documents
What is azure AI language service
Azure AI Services provides direct access to both Azure AI Translator and Azure AI Speech services through a single endpoint and authentication key
What is Multiple linear regression
models a relationship between two or more features and a single label (2 drivers and 1 outcome)
What is linear regression
Predict a single feature
Logistic regression is
a type of classification model, which returns either a Boolean value or a categorical decision
Hierarchical clustering
groups data points that have similar characteristics.
What are embeddings
Embeddings is an Azure OpenAI model that converts text into numerical vectors for analysis. Embeddings can be used to search, classify, and compare sources of text for similarity.
