  Data Science - Complete Track • Step 1 - Identify the business problem/value addition/question – ( Data Insights ) this has to be the starting point. • Step 2 - Data availability ( Data Governance ) - Have the structure of your data set defined – The real challenge starts here-                o Do we have the data?                o Do we have access to the required data? • Step 3 -Getting Data ( Data Mining / Data Pipeline ) – How to collect the data from different sources in the system • Step 4 - Data preparation (ETL / ELT) – Once you have data there will be lot of cleaning and preparation required, reduce/increase/combine/split the predictors, determine and eliminate outliers, populate missing values convert few categorical variables into numerical etc. • Step 5 –Exploratory Data Analysis (EDA) – In this step we do descriptive and diagnostic analysis of the existing data. We build multiple graphs that give us direction towards the next steps of predictive analytics. We migh

    Mixing COVID Vaccine Brands Appears Safer, in some cases is Likely to Cause Side Effects.
      But not Severe. Using two different vaccines will provide greater effectiveness because they work in differently.

      Covid 19 Rapid Antigen Test Kit

      Image
        Antibody tests are useful to help track the spread of a contagious disease , disease that is readily spread. It can be very useful to identify those who should be vaccinated urgently, and to select the donors for convalescent plasma therapy. Antigens are molecules capable of stimulating or encouraging an immune system response. Each antigen has distinct surface features or structures called epitopes, generating specific responses. What are Antibody and Antigen ? An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and remove foreign objects such as pathogenic bacteria and viruses.  These antibodies are produced by B cells of the immune system due to exposure to antigens. Each antibody contains a paratope which recognizes a specific 'epitope' on an antigen, acting like a lock and key binding mechanism. This binding makes possible to eliminate antigens from the body, either by direct neutralization or by ‘tag

      Portable Pulse Oximeter

      Image
        Portable Pulse Oximeter Portable Pulse Oximeter is a noninvasive and painless device to measures oxygen saturation level, or the oxygen levels in blood. It can rapidly detect even small changes in how efficiently oxygen is being carried  to all of its cells, tissues, and organs. Portable Pulse Oximeter can be used to measure oxygen saturation levels along with heart rate. Portable Pulse oximeter can be used to monitor the health of a person with any type of condition that can affect blood oxygen levels. These conditions include: 1 . chronic obstructive pulmonary disease 2 . asthma 3 . pneumonia 4 . lung cancer 5 . anemia 6 . heart attack or heart failure 7 . congenital heart defects How Portable Oximeter Works To measure oxygen level, a probe that looks like a bag clip is placed onto fingertip, toe, or earlobe. Light beams pass through the blood, measuring the amount of oxygen gas. It does this by measuring changes of light absorption in oxygenated blood containing high oxygen l

        Nvidia turns up the AI heat with 1,200W Blackwell GPUs AI's power and thermal demands hit home Nvidia doubles up on GPU compute with second-gen Superchips According to Nvidia its DGX B200 chassis with eight B200 GPUs will consume roughly 14.3kW – something that's going to require roughly 60kW of rack power and thermal headroom to handle. Blackwell's full potential will require switching over to liquid cooling. In a liquid-cooled configuration, Nvidia says the chip can output 1,200W of thermal energy when pumping out the full 20 petaFLOPS of FP4. While Nvidia may dominate the AI infrastructure market, it's hardly the only name out there. Heavy hitters like Intel and AMD are rolling out Gaudi and Instinct accelerators. The B200 "Blackwell" is the largest chip physically possible using existing foundry tech, according to its makers. The chip is an astonishing 208 billion transistors , and is made up of two chiplets, which by themselves are the largest

      KEY PERFORMANCE METRICS FOR BANKS

      Image
      Leadership starts with access to the right information to make intelligent decisions and drive a  data culture . The average bank spends an excessive number of hours per month assembling financial performance reports, then updating, distributing, and  interpreting data . Bank should consider a  performance management tool  designed to automate the entire process, empowering to do less administrative work compiling data and reports, and more time making  data-driven decisions  that impact bottom-line success. Impactful strategic decisions  then start with understanding current performance strengths and areas of improvement by tracking the right mix of key performance metrics for banks metrics and bank KPIs. METRICS: 1. LDR Loans/Deposits Ratio (LDR) – Expressed as a percentage, LDR is used to assess a bank's liquidity by comparing a bank's total loans to its total deposits for the same period. If the ratio is too high, it means that the bank may not have enough liquidity to
