Vector Search in Mobile Apps has transformed the industry and taken user experience to the next level. But how does vector search achieve that? Rather, what exactly is this vector search?
In this article, we are going to talk about it all.
Since it’s the age of AI you’ll hear almost everyone talk about it around. One of the core algorithms of AI is Vector Search.
To navigate the data-rich terrain, Vector Search algorithms have emerged as indispensable tools, offering innovative solutions to institutions worldwide. With the consistent developments in the field of AI and Machine Learning, this whole science of Vector Search and Machine learning algorithms is only going to expand more.
What is Vector Search?
We are going to dive deeper into how vector search algorithms are a great help in enhancing the user experience for modern applications but first, we need to have a look at what exactly is vector search, and even before that let’s answer the question – What is a vector? Vector is a mathematical term meaning a representation of data in a multi-dimensional space. These vectors are used to represent various types of data, such as text, images, or any other structured or unstructured information. Vector Search is an algorithm that searches for information in a vector database by mapping each data item to a vector representation of itself. The key innovation behind vector search lies in these vectors capturing not just the raw data but also the relationships and similarities between data items.
Applications of Vector Search in Enhancing User Experience
Vector Search and all other relevant AI and ML algorithms make user experience tenfold better and this is how it is achieved.
App features that require searching for something can be made more precise, efficient, and less time-consuming by applying vector search as a searching algorithm. Vector search is able to capture the semantic context of certain search terms ultimately improving the accuracy and precision of the search.
No matter how amazing an application does among its users it can always be made thousands of times better when personalization and customization are added to that app for each user. Quite conveniently, vector search enables us to personalize mobile apps through its ability to look beyond the underlying trends and relationships in a dataset. User preferences and behaviors are mapped as vector representations and then these vectors are used to enable personalized content recommendations.
Efficient Information Retrieval
As the name suggests vector search makes the searching part easier and tenfold quicker. With the help of the vector search any kind and size of information can be retrieved within a fraction of a second. Vector search optimizes the search process which leads to faster and more efficient information retrieval that benefits the users in multiple ways.
The system can quickly match user queries with relevant content, reducing the time and effort users spend in finding the information they need within the app.
Vector Space Models?
A very obvious question when discussing vectors is how exactly are data items represented as vectors? “Vector Space Models” is the answer to this question. Vector Space Models are mathematical techniques that map data items to a vector representation where each dimension of the space corresponds to a unique term. The way these models work is by identifying underlying relationships between words, documents, or any other textual elements within a multi-dimensional space.
Vector Search involves finding similarities between data points represented as vectors in a high-dimensional space. This technique has gained prominence with the advent of vector databases, where vast datasets can be efficiently organized and queried based on vector similarity. Vector search’s ability to handle complex data types like images, text, and audio has revolutionized information retrieval, recommendation systems, and even bioinformatics, underscoring its pivotal role in shaping modern data-driven solutions.
When it comes to vector similarity, to establish how similar two vectors are various distance metrics are used. Calculation of the distance metric between two data points to account for similarity or dissimilarity between the points, We have numerous approaches and methodologies, and based on these methods we classify distance metrics into various types.
Vector Search v/s Traditional Search
We understand that you will not be willing to agree that Vector Search algorithms are better than Traditional Search algorithms without looking at facts and figures. So here’s a detailed analysis of the same just for you:
|Semantic understanding of context and meaning
|Keyword-based with exact matching
|Similarity matching between vectors
|String matching based on keywords
|High, understands context and intent
|Limited, relies on specific keywords
|Handles polysemy and word ambiguity
|Vulnerable to keyword ambiguity
|Versatile, works with various data types
|Primarily text-based search
|Efficient, suitable for large datasets
|May become less effective as data scales
|Content recommendation, image search
|Standard web search, database queries
Limitations of Vector Search
Now, of course, Vector Search algorithms too, just like any other algorithm have some limitations to it.
- High-Dimensional Space: Since the dimensional space used to map vectors is multi-dimensional, the data points become sparse which can impact the efficiency and accuracy of similarity calculations.
- Data Quality: The quality of data wholly depends on the quality of the vector representations. If a correct Vector Space Model is not chosen to represent data points as vectors, the quality of data retrieval will have to suffer.
- Lack of Historical Data: Recommender systems using vector search may struggle when dealing with new users or items because there is insufficient historical data to create meaningful vectors.
