InftyReader is optical character recognition (OCR) software that recognizes standard text, but also scientific figures and mathematics symbols. After scanning a document, it can output the content in a variety of digital formats, including LaTeX, MathML, XHTML, HRTeX, IML and Microsoft Word. Assistive technology can then be used to provide speech, Braille, or enlarged text access.
For more information on creating accessible mathematics and science, consult the following Knowledge Base articles: How can math assessments be made accessible?, Are there commercial products designed to make math accessible to students with disabilities?, How can I create math and science documents that are accessible to students with visual impairments?, and How do I create online math content that is accessible to students who are blind?
InftyReader recognizes scanned images of printed scientific documents including Math formulae, an outputs the recognition results in various formats: XML format for InftyEditor, LaTeX, MathML, Human-Readable TeX for the blinds, etc.
Trial use of InftyReader is available with page number limit of 5 pages per day.

I am looking forward to converting equation images to tex/mathml. All the equations are computer printed. So, not so worried about the clarity. We have around 100K images and hence looking for some solution with API access or an on-premise/offline option.
Is $$ \sum_n=0^\infty x^n \over \sqrtn! > 0 $$ for all real $x$?(I think it is.) If so, how would one prove this? (To confirm: This is the powerseries for $e^x$, except with the denominator replaced by $\sqrtn!$.)
GH gave a perfectly valid answer already but the cheapest way to prove positivity is to write $\int_0^1(1-t^n)\log(\frac 1t)^-3/2\,\fracdtt=c\sqrt n$ with some positive $c$ (just note that the integral converges and the integrand is positive, and make the change of variable $t^n\to t$). Hence $\int_0^1 (f(x)-f(xt))\log(\frac 1t)^-3/2\,\fracdtt=cxf(x)$. If $x$ is the largest zero of $f$ (which must be negative), then plugging it in, we get $0$ on the right and a negative number on the left, which is a clear contradiction. Thus, crossing the $x$-axis is impossible. Of course, there is nothing sacred about $1/2$. Any power between $0$ and $1$ works just as well.
Here is another non-answer. In "Asymptotic Methods in Analysis", chapter 6, de Bruijn proves that$$S(s,n)=\frac2\pi\Gamma(s)(2ns\log 2n)^-s\left(\sin(\pi s)+O\left((\log n)^-1\right)\right)$$where$$S(s,n)= \sum_k=0^2n (-1)^k \binom2nk^s$$for all $0\le s\le\frac32$. So at least this explains things asymptotically.
Additional data for Liviu's plots. I used Pari/GP with 1200 digits dec prec, documenting also the required number of terms after which the absolute values of the summands of the series decrease below 1e-100. There seems to be no local minimum...
This comment serves to record a partial attempt, which didn't get very far but might be useful to others. Following a suggestion of Mark Wildon and Arthur B, define$$f_n(\alpha) := \sum (-1)^r \binomnr^\alpha.$$This is zero for $n$ odd, so we will assume $n$ is even from now on.
Explanation for a beginner:
This table represents the truth values of a statement A and its negation (A). The variable A can take on two truth values: True (T) or False (F). The table shows all possible combinations of truth values for A and its negation A. When A is True, A is False, and vice versa.
While smaller examples of TeX can be passed in a single prompt, there will be TeX that is larger than the token limit and so can not be passed in. Possible solutions would be to use existing code that parses TeX and maybe even runs part of the TeX to establish the state at the time, or to train an LLM so that it can infer reasonable values without seeing all of the TeX.
As for trying to extract technical expressions from PDFs that use PostScript, that too is not a good solution as the PostScript is more about giving positions of where to place graphics, all of the metadata from a source such as LaTeX is lost which makes the task much harder. I will note that I did try InftyProject and for a PDF that uses PostScript it is the best I have seen of the few things mentioned.
Years ago I was dissuaded by the fact that everywhere one looked at the problem, everything noted and all apps for sale were based on PDFs that used PostScript. After working with that for a while realized while possible there has to be something with much higher accuracy. Now that many PDFs can be downloaded with the original LaTeX, as noted in the example earlier this is much more productive as not only is the technical expression there in a linear format but the metadata helps the LLMs expand on the result and is much quicker. There are still some dots that need connecting but nothing that appears as a show stopper.
This research introduces PDF2LaTeX, a unique OCR system designed to extract mathematical content and text from PDFs and convert them into LaTeX markup. They use a Conditional Random Field (CRF) to distinguish between regular text and mathematical expressions, they then use two separate models based on a combination of CNN and LSTM (Long Short-Term Memory) neural network architectures, To translate image blocks of both math expressions and plain text into LaTeX.
What would be interesting to know is for the images that generated LaTeX that were not accurate how correct is the expression? What is the confidence level that the expression is correct? In other words it is at times easier for a human to check simple facts that are a hallucination than it is to check an expression that is a hallucination or partial hallucination.
Neural network models enjoy success on language tasks related to Web documents, including news and Wikipedia articles. However, the characteristics of scientific publications pose specific challenges that have yet to be satisfactorily addressed: the...
I am interested in developing a personal chatbot using the latest Langchain framework. The chatbot will be designed to read and analyze academic papers. Although I found several online tutorials on creating chatbots with Langchain, none of them mentioned the limitation of LLM in interpreting technical expressions such as math and other type rules. It seems that the common Python package used for interpreting PDF files in these projects is Pypdf2.
By the way, I have noticed that there are some AI platforms available which can assist you in reading scientific papers, but unfortunately they are not open source. Some platforms, such as Scite and SCISPACE appear to have the function of extracting technical expressions. However, I am not inclined to trust them as they are not open-sourced. I would like to hear your thoughts on them, too.
