    Ma'am clear nhi hua table for the first order context. Like u said h ke bad i kitni bar. I to do bar h par apne 1 kyu liya h ?

    Hlo ma'am , actually I want to know in first order array table why you take cumulative count 2 for the letter 's' otherwise you take the cumulative count 1 even if it comes two times....pls answer ma'am.......

    • @itechnica

      Hi! Actually for the letter "s" first order context is " i", which appears two times in already encoded sequence. That' why the count is 2, cum_count is also 2.

    Mam in first order context u have said that I comes only once after 'h' in the sequence but its coming twice. Am I understanding it wrong or u have made mistake?

    • @itechnica

      Hi! Jaya.
      Actually While preparing first order context table , we only consider the assumed sequence not the whole sequence that's why i comes only one time before h.

      itechnica in the assumed sequence also 'i' is coming two times in t h I s b I s

      Abhishek Sharma Hi! Yes u r right that i appears two times. So while preparing zero order context - the count for i is 2, but in first order context i appear after h is 1 .

    • @yugrawal5541
      @yugrawal5541 6 ปีที่แล้ว

      but still maam why we took i as 1 and s as 2 in first order sequence?

    • @yugrawal5541
      @yugrawal5541 6 ปีที่แล้ว

      Also maam why you say before the context while i think we are checking the symbol counter "after" context :-)

    In the last section of video the formula for Upper Limit will have -1 instead of +1....or not????.....conforming

      Hi! use -1 for calculation.

    Mam i couldn't understand how did you chose the already encoded sequence and why you left e in sequence??

    • @itechnica
      @itechnica  6 ปีที่แล้ว

      jyoti Singh Hi! It is up to you about the assumed sequence that how many symbols are assumed.
      We assumed first seven letters in which e does not encounter.

    Mam your videos are very helpful...
    Mam, can you upload videos on Tokenization, Stemming and Lemmatization, Skip pointers; these are part of boolean retrieval.
    It would be so helpful if you upload these video topics.

      Kindly refer to information retrieval playlist for all these topics.

    can u tell how -1,0,1,2 came why have u taken that ??????????/ and u have assume 7 letters is it compulsory to take 7 can we take 6 or 8 for assuming???????????

    • @itechnica
      @itechnica  6 ปีที่แล้ว +3

      kirti maheshwari Hi! It is not compulsory to take 7 letters. Actually we assumed letters in such a way that it covers maximum letters from the sequence at least once.
      For creating context order table , we always start from -1. It covers occurrence of each letters from the main sequence which help in decoding.
      Thanks

    How came -1,0,1,2

    • @itechnica
      @itechnica  6 ปีที่แล้ว

      Aanchal Srivastava Hi! We have to assume context order. In this question I assuming context order is 2 . So we have create table from -1 order to assumed order i.e 2 for encoding purpose.

    • @aanchalsrivastava8550
      @aanchalsrivastava8550 6 ปีที่แล้ว

      itechnica what does it mean context order -1 etc

    • @itechnica
      @itechnica  6 ปีที่แล้ว

      Actually for encoding procedure we have to check in longest order context table whether it encounters or not.if not, the reduce the context order. As I already discussed that in -1 order table we take each symbol one time which is exists in sequence. So the symbol which is to be encoded is present in -1 order itself.
