Key features:

Single Shot Detection: SSD is a single-shot object detection framework, meaning it performs object localization and classification in a single pass through the network. It eliminates the need for separate region proposal and object classification stages, resulting in faster inference times.
MultiBox Prior Generation: SSD uses a set of default bounding boxes called “priors” or “anchor boxes” at different scales and aspect ratios. These priors act as reference boxes and are used to predict the final bounding box coordinates and object classes during inference. The network learns to adjust the priors to better fit the objects in the image.
Feature Extraction Layers: SSD utilizes a base convolutional network, such as VGG or ResNet, to extract features from the input image. These features are then fed into multiple subsequent convolutional layers of different sizes to capture information at various scales. This enables the detection of objects of different sizes and aspect ratios.

Top 10 Intelligent Virtual Assistants

by rajeshkumarJune 6, 2023June 19, 2023UncategorizedLeave a Comment

Intelligent virtual assistants (IVAs), also known as virtual agents and digital employees, allow businesses’ customers or clients to engage with them in a conversational manner. Conversations conducted with these bots are human like and natural.

A key differentiator between IVAs and chatbot software is the nature of the conversation conducted. While chatbots are typically scripted and do not have the ability to understand multiple intents, IVAs understand a range of different intents from a singular utterance and can even understand responses they are not explicitly programmed to using natural language processing (NLP). With the use of machine learning and deep learning, IVAs can grow intelligently and understand a wider vocabulary and colloquial language, as well as provide more precise and correct responses to requests. In addition, IVAs are able to provide personalized answers based on segmentation or other information provided. They are often focused on a particular job role or use cases, such as marketing, customer service, and sales. This type of software has the ability to use human output as an input to update business systems such as CRM software.

Top 10 Expert Systems

by rajeshkumarJune 6, 2023June 19, 2023UncategorizedLeave a Comment

What is an expert system?

An expert system is a computer program that uses artificial intelligence (AI) technologies to simulate the judgment and behavior of a human or an organization that has expertise and experience in a particular field. Expert systems are usually intended to complement, not replace, human experts. The concept of expert systems was developed in the 1970s by computer scientist Edward Feigenbaum, a computer science professor at Stanford University and founder of Stanford’s Knowledge Systems Laboratory. The world was moving from data processing to “knowledge processing,” Feigenbaum said in a 1988 manuscript. That meant computers had the potential to do more than basic calculations and were capable of solving complex problems thanks to new processor technology and computer architectures, he explained.

Here is a list of 10 notable expert systems:

Logic Programming Paradigm: PROLOG follows the logic programming paradigm, where programs are written in terms of logical statements and rules. It allows programmers to focus on describing the problem domain and the relationships between entities rather than specifying the control flow or step-by-step execution.
Horn Clauses and Predicates: PROLOG programs are built using Horn clauses, which consist of a head and a body. The head represents a predicate, and the body contains logical conditions. Predicates define relationships between objects and can be used to query the knowledge base.
Rule-Based Inference: In PROLOG, the reasoning is based on a set of rules and facts. The system performs backward chaining, starting from the goal or query and attempting to find the rules that match the query, recursively traversing the rules until a solution is found.

10. Deep Blue

Deep Blue was a highly advanced chess-playing computer system developed by IBM. It is best known for its historic victory over world chess champion Garry Kasparov in a six-game match held in 1997. Deep Blue was a culmination of years of research and development by a team of computer scientists and chess experts. It employed a combination of powerful hardware and sophisticated algorithms to analyze chess positions and make decisions.

Key features:

Chess-Specific Algorithms: Deep Blue incorporated specialized chess algorithms and heuristics to evaluate and analyze positions. These algorithms included advanced search techniques, position evaluation functions, and move generation methods tailored for chess-specific characteristics.
Massive Parallel Processing: Deep Blue utilized a massively parallel processing architecture, consisting of hundreds of custom-designed chess chips working in parallel. This allowed it to perform extensive calculations and search large portions of the chess game tree to determine the best moves.
Search and Evaluation: Deep Blue employed a combination of search algorithms, including the alpha-beta pruning algorithm and selective search techniques. It explored different lines of play by analyzing potential moves and their subsequent positions, evaluating the strength and strategic value of each position.
