Presenting the AI directly on your screens

You may have used Artificial Intelligence in your daily life Job works, Schools/ Curricular works or even maybe in your daily life somehow.

But Here is something new and latest that You never have heard or even maybe never imagined . Yes, Here is Sana, the first AI news anchor made by India launched a few hour ago on India Today, News channel. 

"She is bright, gorgeous, ageless, tireless, speaks multiple languages and is completely under my control.

said India Today's Vice Chairperson, Kalli Purie

Sana : World's First AI news anchor

Kalli Purie, Vice-Chairperson of India Today, launched Aaj Tak's first AI anchor Sana during the 20th edition of India Today Conclave, which kicked off on Friday. Purie described Sana, "She is bright, gorgeous, ageless, tireless, speaks multiple languages and is completely under my control." The first AI anchor will be updating us with the daily news several times a day in multiple languages from this week onwards.

She said that Sana will present each relevant news and topic daily and do a show with a question and answer show for the audience to enhance the interaction.

Talking about the innovations she further added, "Sana does not take away from the brilliance of real-life anchors, who will be mentoring her. Sana will have a human surrogate editor and hopefully company soon"

Purie further stated that this partnership is anticipated to unveil innovative wonders, and it is not a contest between individuals and artificial intelligence. She remarked, "The future is intriguing and alarming, and it has arrived." Addressing the persistent criticism directed towards media for displaying partiality, Kalli Purie acknowledged the influence that external forces exert on media. Nevertheless, she emphasized that India Today has always maintained the integrity of their narratives, stating, "Our reliability holds significance for us."

Brad Smith, the President and Vice-Chairperson of Microsoft, along with other distinguished individuals, expressed their views on AI. According to Smith, AI has the potential to become as significant as the internet. He also anticipated the emergence of Generative AI in Indian government services and businesses, which would provide novel methods for citizens to obtain information. During his conversation with India Today and Rahul Kanwal, Director of Aaj Tak news channel, Smith delved into the advantages and disadvantages of Generative AI.

Linear Algebra in Data Smoothing

 

   What is Data Smoothing?

                        Smoothing data is a statistical method that eliminates disturbances and extracts fundamental patterns from a data set. Linear regression is one of the most widely used methods for data smoothing, which includes fitting a straight line or a curve to the data points. In this article, we will delve into the application of linear algebra in data smoothing.

            While before proceeding, let's learn about some other techniques and methods.

Linear Regression;

                            Linear regression is a technique that models the correlation between two variables by fitting a linear equation to the observed data. The purpose of linear regression is to identify the straight line or curve that best corresponds to the data points, enabling us to predict or estimate the value of the dependent variable for a given value of the independent variable.

Matrix Representation;

                             Linear regression can be represented as a matrix equation. This involves determining the coefficients of the linear equation that minimize the sum of the squared deviations between the projected and actual values. The matrix representation of linear regression involves representing the independent variable as a matrix, and the dependent variable as a vector. The coefficients of the linear equation are then calculated using matrix operations, such as matrix inversion or singular value decomposition.

Regularization;

                             Regularization is a data smoothing technique that prevents overfitting, a situation in which the model fits the noise in the data instead of the fundamental trend. Regularization involves adding a penalty term to the cost function that penalizes large coefficients and encourages simpler models. L1 and L2 regularization, also known as Lasso and Ridge regression, respectively, are the most popular types of regularization used in linear regression.

Applications of Linear Algebra in Data Smoothing; Linear algebra is used in several data smoothing applications, such as:

1. Time series analysis: The mathematical discipline of linear algebra is employed to represent the tendencies and configurations in chronological sequence information, like the values of stocks and meteorological data.
2. Image processing: The examination of numerical structures and methods, referred to as linear algebra, is implemented to analyze and enhance signals, encompassing but not restricted to sound signals and detector information.
3. Signal processing: The study of mathematical structures and techniques, known as linear algebra, is applied to scrutinize and refine signals, including but not limited to audio signals and sensor data.
4. Machine learning: Numerous machine learning algorithms, such as linear regression, support vector machines, and principal component analysis, utilize the principles of linear algebra.

Closing Remarks;

To sum up, linear algebra plays a crucial role as a mathematical instrument in the process of data smoothing. Approaches like linear regression, matrix representation, regularization, and other tactics of linear algebra are employed to eradicate unwanted signals and detect the fundamental patterns in datasets. By attaining mastery over linear algebra, data scientists can create effective data smoothing solutions and gain knowledge about intricate phenomena.
